View Full Version : Gamo Shadow Sport

Hello all!
Just purchased a Gamo Shadow Sport for general use, mainly at home. This is my first review on this forum, so I hope this is of some use to you all.
Gamo Shadow Sport .177", 50 Gamo Pellets & BSA 3-9 x 40 scope kit. £149.95 from DAI in Brierley Hill. (Asked to throw in some pellets & I got a tin of 500).
Having seen this rifle on the B.A.R site & the Gamo Shadowmatic, I tried to see if I could get one of them locally. I searched the web & came up with a Shadowmatic for £99.99 at DAI. Next day I took a trip over, only to find that they didn't have any Shadowmatics & were not likely to have any more.
They had several Shadow Sport rifles in stock, with one on display, so after bartering a bit, I purchased one.
The rifle is light & well balanced. Obviously, the lack of weight is due to the synthetic/plastic stock. The stock & grip is comfortable to hold.
The barrel is covered by a plastic/flutted shroud. This is very comfortable to grip & the rifle is easy to cock.
A manual safety catch is positioned just infront of the trigger & is simple to use. Flick forward to release catch & flick back to enable.
Having got the rifle out of the box & after a quick skim through the handbook, I cocked the rifle & loaded one of the pellets. I was perhaps a little too eager to try the rifle & in my haste, didn't check the tightness of the bolts holding the mount to the rifle, with the effect that the scope came off & to my surprise, didn't fly very well!
No harm done to the scope & a valuable lesson was learnt! However, I had some difficulty re-fitting the mount & eventually I found that at the security pin end of the mount, one side was a shade thicker than the other, which meant the scope would not sit in both grooves at that end of the rifle. I shaved off a very small amount of metal using a small modelling drill & mini sanding disc & the problem was solved.
I spent a bit of time setting the scope up at my home, but it will require setting up more accurately at the club next week when I have more room than I have at home.
The rifle is quite loud when it is fired, most of which is from the spring & can be discribed as quite clangy. I feel that this could be reduced some what if the spring was given a bit of decent grease, however, I feel it would still be louder than an equivalent rifle with a wooden stock.
The scope is ok & seems a little better made than my Hawke scope, but the problem I had with the mount was a bit irritating.
In my opinion it is a good buy for a full power rifle for plinking and target practise & with it's synthetic stock it is very easy to look after & keep in good condition.
I hope to fit a Webley Pro System silencer to the rifle if it is at all possible
Out of 3 grins, I'd give it :D:D.

Hello again people!
Have been to the club and have, with the help of Clive, set up the scope on the Gamo Shadow Sport more accurately.
Thanks to Alan & his chrono', the rifle is circulating around the 11.5 ft/lb with Air Arms Field pellets.
It has been reccomended by my mate Clive that the spring could do with a bit of grease.

nice little review of a not so common gun,at that price it would be good for people wanting to try the sport or on a budget , lets us know what u think after u have shot a few targets at say 30 yards :)
cinstone

Hello there!:)
The longest distance I have tried it is about 25 metres give or take.
Yesterday I was shooting at this distance at paper targets, standing up, holding the rifle without any support from a bipod or other rest.
Doesen't the thing move around a bit!:D
I managed to get a "group", for want of a better fraise, of about half a dozen pellets within about 2-2.5 inches. I was using Air Arms 4.52 Fields.
I'm sure a more "springer experienced" shooter would have done better. More practice needed by my self I think!

i have a gamo vipermax
i have the clangy sound as well. you reckon that a grease up would get rid of the sound?
i find it is very accurate up to about 20-25 yards where it starts to drop (at rufley 30yards it was dropping an inch and a half)
the gun is well balanced but when standing and not resting on anything i find that the gun does wobble a bit.

I doubt if a bit of grease would get shut of the twang of the spring, but it would help a bit. The chap from the shop I bought it from said that they had quite a bit of recoil.
For a rifle that you can just take out, have a play, then put it away, with just the occational lube & clean, I think it is a good buy. Light too. Good for kids if they want to try the sport.
As for the gun wobbling a bit, I'm affraid it's me, not the gun!;)

To reduce or even get rid of the twang, check out:-
http://airecomprimido.net/portal/modules.php?name=Content&pa=showpage&pid=22
It's in Spanish but should be self explanatory with the photos.
To improve the trigger, get a trigger insert from:-
http://home.comcast.net/~peterdragin/index.html/default.htm
Only $8. Works like a dream and gives a real two stage trigger. Transforms the gun.

I've had a look at that Spanish website & have seen the photo's.
Adding what looks like heavy duty sponge around part of the spring should work, but I doubt if it would do for long. Mind you, I may not have interpreted the photo's correctly.
derekm

Hi Cinstone,
You may well be right that the sponge won't last long; I was just repeating what I found. Having said that, there is space around the spring and with good grease, it may last a while. I've done it to my Baikal pistol and it's holding out after a few hundred shots so far.
I've just posted a review of the CFX and in it there are details of another mod. that definitely works and will stay the course. Take a look.

Morning all!
I've managed to get the spring out of the Gamo so I can clean & re-grease it & hopefully reduce some of the "twang". This was the first time I've taken an air rifle apart, so it was a little bit of an adventure.
The only trouble I had was finding out how to get the collar out of the cylinder that holds the spring in. Thanks to a link to a Spanish website in a posting by derekm, I managed to work it out.
Here's what I did;-
1, Remove the two bolts out of the front of the stock, near the breech. There is one on each side.
2, Remove the rear bolt from the trigger guard. Be careful you don't lose the small washer underneath. Fortunately, mine fell into the stock, so I was able to "rescue" it.
3, Lift the action of the stock & remove the plastic end cap from the rear of the cylinder.
4, Pull off the plastic guide grommet & its washer from the side of the cocking lever. Also remove the small "U" shaped plastic clip that clips onto the cocking lever. When fitted, this prevents the lever touching & marking the cylinder.
5, Disconnect the sping on the link between cocking lever & the trigger unit.
6, Disconnect the circlip holding this link to the trigger unit.
7, Remove the metal guide from the rear of the trigger unit. This slots into the stock when the action is fixed into the stock.
8, Remove the plastic clip/spacer from the rear of the trigger unit.
9, Using a 10mm open ended spanner, undo & remove the trigger bracket bolt & the bracket.
10, Using a hammer & suitable "punch", gently start to tap out the pin retaining the collar that holds the spring in. OBVIOUSLY BE VERY CAREFUL DOING THIS AS THE SPRING IS STILL UNDER SOME TENSION. Some sort of clamp would have be the best way to do it, but not having one I had to improvise.
11, Once collar is out, just pull out the spring with it's rear spacer & rod.
12, After this, remove the trigger unit by sliding it back & moving the unit slightly to one side or the other, allowing you to remove it from the cylinder.
13, Slide out the piston & it's slider.
I'm at the stage now where I have cleaned up the parts & all I have to do is grease the spring & slider, lube some of the parts & put it all back together.
I'm yet to decide what grease to use on the spring yet. Ideally I could do with something quite thick to help cut down the "twang".
I appologise for some of my terms & names for parts. The Gamo handbook is more or less useless & there are no diagrams or lists of parts for refrence.
derekm

You see, it wasn't difficult was it? Before you re-grease it, I suggest you clean all the surfaces and remove all burrs and sharp edges, wherever you find them, then re-grease and assemble.
For the spring, I checked what the Americans call spring tar, to reduce twang and I quote Rich from Mich:-
"Spring tar is black and real sticky it's made by Lubriplate and it's
called Gear Shield extra heavy, this is what I and also Maccarri sells
as spring tar."
Myself, I used CV joint grease, a lithium based moly grease, which is also very gloopy. Used neat on the spring and diluted with airgun oil for other sliding/pivoting parts. Available from motor factors for around £2.5 a large pot.
I've also just received a can of spray moly from Paddy SP (search on this forum). This leaves a dry coat of moly on the surface sprayed. It will be used after the next strip, whenever that is.
Now you're not a stripdown virgin, when are you going to order Rich's tuning kit and trigger mod?
cinstone
08-02-2007, 02:57 PM
I may have dismantled it, but I've got to get it back together!:eek:
As the piston is some form of plastic, would you put anything on the skirt? If so, what?
I thought about using copper ease on the spring.
Inside, everything is quite good. Not too much in the way of burs etc.
Thanks for the tips. Most useful. As for the tuning kit, I will attempt to put it back together first, then see what it is like.
The next one I'm going to mess with is my dad's old Relum. It works at the moment, but I am going to put in a new spring for starters.
By the way, any tips for putting the spring back in, on my own, without a press?
Cheers!

08-02-2007, 03:41 PM
Chris,
I wouldn't use copper grease inside the gun. The particles of copper may be quite large and may not mix too well with the seal. I suggest the CV joint grease; enough for 50 strips for £2 odd and is more gloopy than coppercote.
While the spring is out, try to round off the cut ends, so they cannot cut into the spring guide or the underside of the piston crown as the spring turns under compression/decompression.
Are you sure the piston is plastic? Mine is hardened steel, with a synthetic (plastic) seal. Same moly grease, diluted somewhat, on piston skirt where it makes contact with cylinder and a little on rear of seal lip. Wipe a thin film of grease inside the cylinder, before inserting piston and take care to ease the seal over the sear slot and cocking slot, with a small implement. On the CFX, if you look closely, the steel piston is waisted, so it only touches the bore immediately behind the seal and at the rear, by the sear engagement. I would be surprised if the Shadow is any different.
See my CFX review post 3, re. spring compressor. If the Shadow is similar to CFX, it should be possible to use your weight to compress the spring and have an assistant to replace the pin. Wear a leather glove in case you slip. My wooden blocks worked a treat single handed, if you can understand the explanation!
When dismantling or reassembling, tie back the sear on the trigger assy. with a rubber band or similar so it doesn't tangle with the spring coils.
Good luck!

Morning.
Good point about the copper ease grease.
I may get some grease this afternoon & see if I can get it all back together.
I think I will list a competion post...."Guess how many parts I have leftover"!:D
The piston is steel with a plastic seal.
Thanks for your help!:)
Chris I.
cinstone
12-02-2007, 06:55 PM
Evening!:)
Well it's all back together & I have not one part leftover!:D
Managed to get the spring back in by myself, holding the spring back with my left hand whilst putting the retaining pin in just enough to hold, before tapping it fully home.
I was surprised how easy it was to get the spring back in.
What I can tell you all is that using the grease & tips provided by derekm on this forum, the "twang" of the spring has totally gone!:D
However, not all is o.k.
Not that long after I bought it, it was chrono'd at around 11.5lb.ft. On one occation it was putting out 9.6lb.ft.
Before I took it apart I chrono'd the rifle & after 20 shots the average reading came to 736.05 = 10.10lb.ft.
At this stage the rifle was due a bit of T.L.C., i.e. the barrel was due a clean & a bit of lube here & there.
After putting it back together I shot 20 pellets. As already said, the "twang" had gone & the rifle now had a healthy "thwock". There has be no sign of "dieseling". I then cleaned the barrel, which was quite grubby.
I then shot another 100 pellets & was thinking...."This is great, I'm more accurate with it, it sounds a lot better, a lot less vibration. Why did they not put some decent grease in it in the first place?"
I then shot 25 pellets & took readings using my chrono';- 639/660/658/653/653/655/662/651/648/642/661/654/648/654/643/666/659/662/661/646/645/643/663 & 661. Average f.p.s. of 654.2 = 7.98lb.ft.:(
So, thinking it may need running in a bit, last night I put 100 pellets through it. The last 5 shots I chrono'd & got 644/660/650/646/642 = 7.84lb.ft.:mad:
I then shot a further 100 pellets & chrono'd the last 5 & got readings of 650/631/638/635/647 = 7.64lb.:mad:
Before taking it apart again, I am at a loss as to why the power has dropped off so much.:confused:
Obviously I've checked the breech seal & it looks o.k. Of course, when I put the piston back in I could have damadged the seal, but I didn't notice that I had.
At the moment I suspect the spring. I put a spring clip on the spring when I took it out so that I could remember which end went in first, so it ought to be in the right way. But what sticks in my mind is the fact that the spring went back in quite easily, without too much effort & it make me think the spring is a duffer.
I've tried the odd shot with it tonight & got 656/657 & 657f.p.s.
Any thoughts?
Tar in advance.
cinstone
22-02-2007, 11:25 PM
Well it seems that I have damaged the spring.
I've e-mailed B.S.A. & they say that a new spring is 11" long. Mine is 9 1/4"!:eek:
It being this this short makes me think it might have been the wrong spring in the first place.
New spring, piston/seal & slider to be ordered tomorrow direct from B.S.A. for £12 + £2.50 P & P.
derekm
23-02-2007, 10:17 AM
To drop from 11" to 9 1/4" and losing power at the same time sounds like a bad spring, wrongly tempered during manufacture. If it was a good quality but wrong dimension (short) spring fitted from new, you would expect power to be low, but consistent.
How old is the gun? Any chance of gently pushing them for a warranty/goodwill replacement? I know youv'e stripped the gun yourself, but a new spring would cost them less than the carriage on a warranty repair and they have no labour involved. 11" to 9 1/4" would seem to be cut and dried; something is wrong and it cannot be your fault! Stress that you are a responsible adult and not a pimply chav! It may work. I lost a trigger spring from the CX (my fault) and they sent me a couple with compliments.
Just re-read your post and noticed you emailed them. Try phoning and chatting with someone out of the repair dept.. 0121 772 8543
cinstone
23-02-2007, 11:50 AM
Morning!
I will be ringing B.S.A. later today. They gave me the phone number to ring & who to ask for.
I doubt they will give me a free spring as I have taken the rifle apart myself, but it has been interesting to take it apart.
I'm going to order a new slide, piston/seal assembly as well, just incase I've b******d them up too!:D
Cheap bits though, £12 for spring & piston/seal/slide assembly.
By the way, your "C.V." grease is lovely stuff to mess with. Nice & thick, mind you I couldn't get it for less than £4.20 around here. Lets hope with the new spring it is still "twang" free.
I'll keep you posted.
derekm
23-02-2007, 12:38 PM
Sounds like you paid Halfords price for the grease. Not to worry, it will probably last you for years.
I always go direct to the motor factors who supply the garage trade. There are always two or three in any town.
At a tangent, for DIY, my last call is B & Q. I go straight to the builder's merchants for half the price (or less). Don't worry that these are "trade" suppliers. Anyones money is good and with cash, they get paid, with accounts, sometimes they don't!
Don't forget to publish the figures of the Shadow with the new spring.
cinstone
23-02-2007, 05:20 PM
Afternoon.
I went driving around trying to find the right grease. The ones I did find were £5.50 a tin.
I got a tin of Comma C.V. Grease from a small motor factors a few miles away in the end. Hadn't been in there for years & now they seem a little more pricey.
I generally try Wilkinsons first for anything like D.I.Y. stuff. Very cheap, but they don't always have what you want.
I phoned B.S.A. this afternoon & spoke to John in spares. Decent chap. Told him the problem & he said that in the Shadow Sport it's a 10" spring with 34 coils. I checked the amount of coils in mine & it came to 34. He went to check the length of one of the springs & rang me back. It does seem that it's my fault, but he is sending me a new spring & a new piston seal F.O.C. They should be here tomorrow morning.
He did say that I should have taken it over to them as I'm only "down the road", but I told him that all I wanted to do was grease the spring as it was so "twangy", and that sometimes it's nice to have a play!:D You've got to start learning somewhere.
Forgot to mention. He told me that they had had 144 of the Gamo Shadow Sport kits in just before Xmas & they have all gone.
Next update to follow. Maybe not today. Maybe not tomorrow, but soon...........

It costs nothing to ask and sometimes it pays off! Why was it your fault though, as you only stripped and greased the gun?
cinstone
23-02-2007, 08:13 PM
It's just my own opinion that it was my fault. Anyway, I now know how to take it apart. I'm just wondering if I can remember how to put it back together!
I reckon it dieseled a bit & after reading a book down the library which reckoned if the spring had been damaged in this way, it would have some coils closer together at one end, with the trigger end being the more likely the end where this would occure. This has happened & it's at the trigger end.
With the info' given in the first place of a new spring being 11", I wasn't so sure.
Anyway, new parts on the way. I was willing to pay, but John said that he would send them F.O.C.
I'll let you know what happens.

Afternoon all!:)
The new spring & piston seal arrived this morning in the post from B.S.A. F.O.C. Only phoned them yesterday afternoon. Can't get much better service than that!
I didn't have much time to play today, but I did manage to do a bit.
I took out the piston slide, cleaned it off & checked the piston seal. There was slight ware on the seal, so, with the aid of a small screwdriver I managed to get the seal off.
Putting the new seal on was not going to be quite so easy. To try & help, I put the slide in the fridge for an hour or so & just before trying to fit the new seal, I put the seal in a cup of hot water for 5 min's. On the third attempt I managed to get it on. The easiest way to describe how I did this is to imagine you are putting on a bike chain after it has come off. On a bike you would turn the chainwheel slowly to get the chain on. With the seal a small screwdriver replaces the chainwheel, but you move it around in much the same way.
Hopefully I shall get round to getting it all back together on Monday.

24-02-2007, 02:35 PM
Just a thought, but if by Shadow Sport kits you mean spring/seal kits and BSA/Gamo got through 144 since just before Christmas, they must have had a bad batch and hence their willingness to replace FOC. At least they seem to have owned up to it.

25-02-2007, 10:41 AM
The Viper Skeet uses a mini mini shot cartridge, or with a breech adaptor, can fire .22 pellets. Do a search on Utube and the US Forums. There's also a video clip on the Gamo website; looks fairly impressive there, but it is advertising! The US general opinion of it is not particularly high.

26-02-2007, 06:38 PM
Evening everyone.
I managed to get it all back together this afternoon. It was more difficult to get the new spring in than the old one, but I managed to get it in by myself.
After putting it all back together I tried 10 shots. It diesled for the first 4 shots, but was clear after this.
I then chrono'd the rifle using Air Arms Field 4.52s weighing 8.4 grains.
26 readings taken as follows;- 753/753/760/759/755/763/760/742/751/756/758/766/760/769/766/785/752, (it then dieseled again for 3 shots, these were ignored), 766/750/769/764/748/772/772/761/771.
Average F.P.S. over the above 26 shots = 760.8 = 10.79lb.ft.
I have shot another 163 pellets & when I've shot 500 I will chrono' it again. Ideally I would like it nearer 11.5lb.ft. If it is close to this when I next chrono' it I will leave it aloan, but if not, I may try to get it closer to 11.5lb.ft.
As for the "twang", it is still there. It's not as bad as it was before I took it apart the first time, but it's twangier than it was when it had the old but damaged spring in it. The stock is hollow, so I have filled this with bubble wrap to see if it deadens the twang. So far it may have reduced it by a fraction, but something more robust is needed.
The rifle is smoother to cock now though, but I would like to fit some new plastic protectors to the cocking arm that protects the cylinder from damage. I'd like to make my own, but I'll have to have a think of what sort of plastic is best to use.
Next & hopefully the last update to follow in a few days time.

Hi,
Take a look at the edit in my CFX review. With 7gr Hobby, I'm now running 11.52fpe, but with 8.3gr RWS Superdome, it drops to 11.03fpe. Your 10.79 isn't too far behind and with a heavier pellet.
I asked the question on here about a week ago re. pellet weight and power output. With a springer, the heavier pellet gives less power, with a PCP, more power. Try some Hobbys or similar weight to see what you get. The 12fpe is supposed to be with any pellet, so if you got 11.5 with AA Field you would probably be over the limit with say Hobby.
Cocking arm protectors are $5 from Rich and you could get the trigger mod at the same time!
cinstone
27-02-2007, 01:18 AM
Hello derekm!:)
Surely it would be simple to make some cocking arm protectors ourselves. Just need to find some suitable plastic. Mind you, the Shadow Sport is cocking at its smoothest since i've had it at the moment.
I clocked up the shots to 251 this evening with AA Field 4.51s that I use in my pistols & for messing about & testing etc. Will do some more over the next few days with 4.52s. I'll see what it is like in a few days time & then decide what i'm going to do. I have some RWS Superdomes that I haven't used. Any idea of the weight of these? Not at home at present so can't check.
I'm happy with the trigger at the moment, but I wasn't this afternoon. I managed to get the spring in at the third attempt. Got pin in just enough to hold, then tapped it home. Then I looked for what was next to do. Yes I thought, secure the trigger. Yes the trigger I thought. Trouble was I hadn't put it in before securing the spring!:o
Interesting stuff though.
Although only slightly, packing the hollow stock with bubble wrap has helped a bit with reducing vibration. Not that it is that bad, but as a certain advert says "every little helps". I was thinking of trying expanding foam. Do you know if this stuff goes off hard, or is it a bit soft after it has been used & allowed to set?
derekm
27-02-2007, 10:07 AM
Hi
I just didn't think it worth the effort making cocking slide protectors to save $5.
I was wondering myself about foam for your stock. IMO it would have to be polyurethane foam as used for surfboard cores. This sets hard and can be "worked". I'm sure it's available in spray cans.
If you want to increase the weight/change the balance of the gun, you could try plasticine or electrical insulating putty. A few of the Yanks have used this with sound damping success.
Superdomes are 0.54gram, 8.3grain.
cinstone
27-02-2007, 01:35 PM
Afternoon.
I would have though that whatever you put in the hollow stock, it would have a better chance of sound deadening if it remained slightly soft when it had gone off. Still, it's got me thinking.
Cheers!:)

I have a Shadow 1000 and I have filled the stock with expanding foam.
It all got a bit messy as it expanded but when dry it just came straight off the stock no problem.
I use JSB Exacts 4.52 but you will find the AA's the same but the exacts seem to be the most accurate etc.
I have the trigger mods and a full tune kit with maccari spring etc and the cocking slides. The grease etc that comes with the kit is superb at stopping the twang completely and is well worth the effort.

Hello Lardy1.
Did the foam make much difference to the noise/vibration?

Was about to tweek my B.S.A. Spitfire tonight, but I haven't got the right size allen key, so I spent the time trying a few more shots with the Shadow Sport & doing a chrono' test.
First I shot 10 A.A. Field 4.51 pellets.
I then attached the chrono' & shot 10 with A.A. Field 4.52s.
Readings as follows;-
769/770/760/769/757/769/755/773/772/774 = 766.8 f.p.s. average = 10.96lb.ft.
A small increase on the test from last night.

Your AA Fields are a touch heavier than my Superdomes, so your figure of 10.96 would appear to compare with my 11.03. A 7 gr should give you about 11.5 so it's round about where it wants to be. If it comes up a little more it's a bonus, but it will be close to the limit with a light pellet.

Evening everyone:).
After trying the Gamo Shadow Sport down the range yesterday & not being able to get much in the way of good groups, I decided to have a play with the rifle at home. Anyway, it was me, not the rifle.
Anyway, I did some more chrono' tests.
The first 10 shots read as follows;-
769/766/757/764/761/761/766/763/757/772 = 763.6 average f.p.s. = 10.87lb.ft., 0.09lb.ft down on the previous test with a maximum difference from highest to lowest f.p.s. of 15.
I tried another 20 shots & these were;-
763/752/779/757/771/767/760/772/757/757/769/767/769/755/766/772/772/765/775/759 = 765.2 average f.p.s. = 10.92lb.ft. Maximum difference between highest & lowest f.p.s being 27.
While I was at it I calculated the lb.ft from all of the 65 test shots so far & this = 763.43077 average f.p.s. = 10.87363lb.ft.
So far I have put 430 pellets through it since putting in the new spring & piston seal. I doubt if there will be much more of an increase in the power & it seems to be settling down to around 10.9lb.ft, however, I will continue up to 500 shots & then take a final chrono' reading of about 25 shots.

Afternoon everyone.
I've just clocked up 500 shots with the Shadow Sport & have chrono'd it for 25 shots. Readings as follows;-
773/775/763/769/775/777/771/763/753/772/768/766/766/772/775/764/763/762/774/772/763/763/760/778/769 = 768.24 average f.p.s. = 11.011058lb.ft.
Highest reading = 778 f.p.s.
Lowest reading = 753 f.p.s.
Difference = 25 f.p.s. (A couple less than the previous test).
It seems to be settling down now. I'll keep an eye on it over time & let you all know if things change with it.
Cheers all :)!

Hello White_Eagle.
You may find that your rifle may need a regrease.
There are fairly cheap mod's for the trigger & spring available from a chap in the U.S.
For Info' on these check out derekm's review on his CFX Royal.
Forgot to mention about the pellets. I use Air Arms Field 4.52s mostly, but sometimes I use 4.51s.

Hello White_Eagle.
Yes I would agree with that generally.
Put around 500 pellets through it & see how you get on with it. It may not be as "twangy" as mine was.
All the info' about taking mine apart is in the above review & it's updates & you may find some more info' in derekm's CFX Royal review.
If you've taken springers apart in the past you won't have much trouble with the Gamo.
Mine was the first one I had taken apart & it wasn't too bad at all.
For grease on the spring I use C.V. joint grease that you can get from motor factors for between £3.50-£5.00 & it will last you for years.
For the full story, see my review.
Any problems just ask me, or if I don't know, which I probably won't :D, i'm sure derekm has all the answers.

Hi guys, just arrived from the airgun seller and ive decided to put a bi-pod on it as the Shadow is quite long barrel what do u guys suggest?

Hello again.
None of my air rifles have a bi-pod. If I need to rest a rifle in that way I use a small cushion that I rest under my left forearm. Only thing i've used a bi-pod on is a .22" rimfire. They are very convenient, but on a springer it may restict you in allowing the rifle to move freely when you shoot it.
I suppose a cheap way to try it would be to buy one of the cheap plastic clip on types of bi-pod that fit on the barrel. I think you can get them for under £10.
Let us know how you get on.

So you are pleased with it then?!
My Shadow Sport has been on loan to my brother in law for a couple of months. I did get to use it last week whilst I was at his place & it is still fine.
