Crosman P13XX rear sight for steel breech

thingiverse

Look no further, this is only Crosman P13XX rear sight for the steel breech you need to try. I just works. I tried many other designs on Thingiverse and none worked well or up to my standards. So I designed a new one from scratch and I share it with you! Left to right adjustment is locked using a M3 screw. I used a 4.5mm because that's what I had on hand, but I had to be careful not to screw it all the way down. A 4mm long M3 screw would probably work better here. DO NOT overtighten the M3 screw or you will break the dovetail base. Stop screwing as soon as you see the dovetail base lifting a tiny bit from the breech. The M3 screw is there for security, but the part is snug and won't slide left to right once installed if no excessive pressure is applied.
