View Full Version : Charity Appeal - Help the Trminally Stupid

I've just rebuilt and restored an old springer and was trying it out today (albeit with a cheap crappy scope).

Couldn't hit the proverbial 'coo on the ar$e with a banjo' so took the scope off and aimed down the barrel and got reasonable groups. Pinned a MASSIVE sheet of paper to the wall and fired another bunch of shots with the scope back on. It's firing about a foot low over 20 ft and can't adjust it out with the scope. I'm probably missing the bleedin' obvious, but with fixed mounts, all I could do would be to shim the back mount (???) (I think). But this would possibly deform the tube, would it not ? Only other thing I could think of was buying adjustable mounts.

Just realised today, I've owned guns for almost 25 years and never mounted a scope before !!!!!!

Any advice greatly appreciated.

Sounds like a case of barrel droop!

Peter That's what you get for lubricating the piston with Special Brew :D.

Barrel droop ? It must be under stress at work or something.

Did a search for Molybdenum Viagra on the net but couldn't find any. A gap in the market I reckon.

Anyone got a serious answer ??? :p :p :p

Foot_loose was being serious. Theres a mount made to compensate for a drooping barrel.

You can also pack the rear mount with 35mm film negative. But be very careful when you tighten it up because, as you say, you can crush the tube.

Now we have to enter the main issue again but it is fine with me anyway. No problemo !

Yes, you may crush or bend your scope if you donīt mount it correctly. In others words, you need ring alignment then you mount the scope. This can be done in 3 different ways - you deside what way you like it.

1.) After you have mounted the lower rings/mounts at the right eye relief position and tighted the mounts firmly. You can lap your lower halfs of the rings with a lap bar to ensure ring alignment. This is the easy way of doing things.
Just remember if you remove the mounts again or they move because of any recoil, you will need to lap again.

2.) You can use the epoxy method to ensure ring alignment. But it is a little harder way to go.

3.) You can get special scope mounts to take care of the ring alignment problem like Sakoīs Optilock rings.

I hope this can help you some. The ring alignment problem should be taken very serious then you mount a scope.

Please can you enlighten us as to the 'epoxy' method of aligning scope mounts.

I know this is a pretty obvious thing to say and I wouldn't be saying it if it hadn't happened to me! When I received my 50mm nite-eye scope I tried to fit it to my MFR. I hadn't realised that I would require some mounts to raise the scope higher to stop it fouling on the barrel! (Doh!):eek:
I only realised my mistake when I was shooting about a foot low!
Luckily I hadn't over-tightened the scope and didn't bend the tube. I have since aquired the correct mounts and am now happy with the setp.

Hi Tony,

It is actually simpel. You mount again the scope mounts and tight them firmly like you do with the lap bar method. But instead of lapping you make an almost precise shape of the scope down into the epoxy glue (which is put on the lower ring halfs) by pressing the scope down and hold it there until the glue begins to harden.
The area where the scope contacts the epoxy need to be covered with either a very thin layer of tape or best you could use some sort of vaseline to protect the scope from the glue.

Actually this method is very good because you make an exact copy of the scope body and some people reports that the glue holds the scope better under recoil !

I hope this helped in understandig the epoxy glue method. Else try a search on Google for this ring alignment problem.

Springer and scope?

Haven't I read somewhere that 'break-barrelled' rifles tend to point downward and scope mounts are available to accommodate this?

:confused: :confused:
