Ruger Mark I Air Pistol Rear Sight
I broke my fiber optic rear sight and decided to print a new one. This is a fixed rear sight. You can still adjust for elevation, but not windage. Regardless, it functions very well. For best results, print in a contrasting color (unlike I did)!
Print at 100% infil, 0 shells. Clean up holes a bit. See image for how assembly should look.
