Rear Aperture Sight for a Beeman R1?

[Garandimal]

Rear Aperture Sight for a Beeman R1.

Need one. Can't use the OEM Patridge rear sight for squat any more, and have Apertures on all my iron sighted rifles.

...except the Beeman R1.

Currently have a scope on it... that a relative was nice enough to borrow and break.

So I figured it's a good time to go back to irons, as my boys are also getting big enough to cock and shoot it.

TIA.

Would the one made by Williams be of use ?

I just put a peep sight on my R7 and like it. I also got a 0.05” aperature too, that makes it easier for me to shoot tighter groups.

I forgot to mention that the sight comes with an Allen wrench, but you’ll also need a micro flat head screw driver. The directions that were with the sight are generic for multiple sights and could be better. Be sure to loosen the set screws when adjusting the sight. There are two for the elevation and one for the windage.

Thanks CR.

Looks pretty slick.

Noticed that they offer an FP-AG sans knobs.

As I plan to set it and leave it, that might be even better.

RE: the 0.050 Aperture.

Is that bigger or smaller than OEM?

EDIT: Just read that OEM is .093"

Looking for a < 2"@25 yards field rifle.

I was thinking about getting one too, since somebody else was asking about aperture sights here not long ago, but what about the front sight? I have a HW77 which doesn't have a dovetail under the front blade just a rectangular post. 
Does HW sell adapters or something similar?

I haven’t shot at 25 yards, but have shot at 21 yds. The R7 and sight at capable of close to MOA groups at that distance. I’ve gotten a few .25” groups but not often. The limiting factors are my eye sight and skill...

Well...

Received and mounted the FP-AG rear Aperture sight on the R1.

The instructions were poor.

You need to:
- Set the dovetail clamp lightly with the allen set screws.
- Then lightly set the top screw.
- Then torque the allen set screws.
- Then torque the top screw.

If you follow the instructions, the mount base will flex and bend, leaving a gap between the clamping jaw and the base.

Other than that, I set the base just ahead (~ 1/16") of the safety, so that the safety was centered b/t the sight base and the rear of the receiver.

Safety operation is unencumbered,

The stock aperture's optics work great, with plenty of field of view.

Have a minor issue with the rifle, however.

This R1 is a carbine, and has a few degrees of up angle on the Bbl/chamber block.

So, with the sight run all the way down, hard against the base (which is good), the rifle shoots ~ 2.25" high at 20 yds with the std. front sight, and the Benjamin CYL pellets I am currently shooting.

What this gives is a hold of just a hair over half way between the top of the post and the top (inside) of the ring.

I don't know if the alpha can be corrected, and it didn't seem to concern the Air-rifle Ferrari mechanic that overhauled it not too long ago.

The Benjamin CYL pellets are shooting ~ an inch at that range, but have a pile of JSB Diabolo Exact on the way.

Suffice to say, the rear Aperture sight is awesome. Should make the R1 a great field carbine again.
