Peep sights

[TonyL]

throwing another into the mix, I will probably get laughed at for this but SMK do a rear target sight which is available for £40

I have one I bought a while back, I am tempted to put it onto my HW80 with the CS600 Tyrolean stock.
I suspect it is for their QB78 target CO2 rifle so it would probably need drilling and tapping for a recoil pin (e.g. a short M4 or M3 screw, black).
It is adjustable for windage and elevation.

Sorry I got a little confused and posted this on an older thread, but I have just copied it across.

The thread on the SMK and Gamo units is very fine and in alloy.
It strips easily, especially the windage.
It can be repaired by epoxying an M4 fine nut on the body.

I too posted on the older thread. For completeness I have copied here.

I had sometimes looked at these target designs on-line and had always assumed (could be wrong) that they might not be sturdy enough?

Until very recently Protek were showing a Milbro item that looked like it might be okay (although you can't really tell until you try it?), but my usual dithering now sees them sold out.

Seen a scope ring modified to provide the aperture mount. Robust and readily available in different rail widths

Exactly my train of thought, sir.

That looks awesome, doesn't it? I had viewed them before as well as the Ghost Rings on the Brownell site. Must do more digging.

I've often thought about the HW77 block and rear sight and modding it. But would not want to alter a minty one. Now, if I stumbled across a very cheap used one.....

There’s the cheap copy that came on SMK DB4 underlevers as well..

It’s the leaf on the 77 that needs modding so this part can be swapped out if you want to return the sight to pristine.

when you re-pasted your reply it mashed up the link.. herewith: https://southlondonairguncentre.co.u...diopter-sight/

I have one of these - fine for recoiless guns, but not strong enough to clamp up on a springer dovetail IMHO.

It is a bit flimsy, and having two arms rather than a block (as I just discovered looking at mine) there is no way to put in a recoil pin.
I have clamped it to the dovetail on my HW80, I will see what happens when I shoot it.

I think I might know where one of those horrible DB4s might be lurking.

Thank you.

Perhaps searching the terms "Diopter sights" or "Biathlon sights" will get you more info than calling them "peep sights"

Well my experiment with the SMK diopter sight on my HW80 was a failure. The POI was very high, with not enough adjustment to bring the POI to the POA, at least at 10m, which is all that I can get in my back garden. I suppose this is because the foresight on the HW80 is too low for a diopter which sits much higher than the HW80 open sights (yes, I have the rifle, not the K). Also at 10m the full range of adjustment on the diopter gave me only 5cm top to bottom on the target.
Ideally then I should use a peep sight like the Williams but my stock is a CS600 Tyrolean, which puts your eye line perfectly in position for a 40mm scope, unlike the original HW80T. The diopter centre is also about that height. With this stock I can’t get get down far enough to use the normal rear open sight, so would have difficulty using a Williams peep sight.
So my options are at the moment to go back to a scope, but I have 4 underlever rifles that I use on targets so the HW80 would get sidelined, to raise the foresight but it would have to come up a lot, or to try something similar like a red dot. Of course I could go back to the sporter stock and use a lower peep sight or try it at the range with the diopter to see what it’s like at 35 yards.

Hello Eric what height rearsight do you need and I will see what I can find in the bits box.

I had a Gamo style dioptre a few years ago - I expect it is a similar design - and experienced the same. It lacked a recoil stud, and would slide back on the cylinder during a shooting session, too.

I am put off buying a Williams by conflicting reviews on forums; several people on various forums report finding the low sight line model too low to adjust for HWs, while others find the high model too high. I occasionally think of a second hand Anschütz, but they don't come up for sale very often. More common (at least here in the Czech Republic) are the Haenel sights; does anyone know what these are like, and what rail width they fit?

Hi Alistair
Because of the stock design, my eye line comes up perfectly to the diopter sight, so the rear sight height is fine. I need to raise the foresight if I am carrying on down this route. I will carry on with a few little experiments.
I just compared the SMK diopter with those on my Anschutz 250 and SuperAir 2001. Even with the SMK at the bottom of its adjustment it is still a lot higher than the Anschutz diopters, by about a centimetre, and they do have higher foresights. The Anschutz diopters, and the Walther ones on my LG55 and LGM-1 also have more range of adjustment in elevation.
I have found a NSRA coach called Stephen Batchelor who advertises 3D printed sight risers and ordered two for my HW80 foresight, 1 of 11mm and one of 15mm, only £6.50 each. I’ll see how I get on with them.
This is fun, it will be good to get this little issue sorted!

It would be interesting to see if you have anyone offering sight risers for the Williams in the Czech Republic, there are a few people around offering printed accessories around Europe - I bought a printed foresight and inserts from Poland a while back

Sounding good, Eric. Do let us know how it goes for you.

Yes. It will, cheers. Quite a few to be found (generally of the more pricey target ones) and I've made the odd note of one or two over the years.

Bargain solution!
