Decided to put a diopter sight on my .177 HW50S. I got a sight in a trade that I've seen sold under many names. It's identical to the sight that came with my Daisy/Avanti 753S. Well made, tight and positive clicks. But no matter how tight I torqued the clamp, it would creep backward with every shot. I machined a steel stop pin to match the size of the holes in the top of the Weihrauch receiver, and pressed it into a corresponding blind hole I drilled into the underside of the sight body. Problem solved.
I didn't like the empty holes on the breechblock where the original rear sight was, so I took an R/C aircraft product called Monokote Trim in gloss black, scuffed it with scotchbrite, cut a piece to size, and stuck it on top of the breechblock. It's super thin, durable, solvent resistant, but can be peeled off with a bit of effort and a thumbnail. Non-permanent, blends perfectly with the polished blue, and makes the holes disappear.
I verified the sight isn't creeping, and managed to dial it in at 25 yards with some cheapie 7gr RWS Hobby pellets, when once again the wind and rain cut my session short. Plinked a couple cans real quick at about 35 yards and I think I'm going to like this setup. I used the front sight insert with the skinny post and ball on top. Perfect! And wow, the rifle is so light and handy without a scope.
Just waiting for some clear weather...
