At some unknown time when I was doing some modifications to my 10/22, I lost one of my receiver pins. I crawled around on the floor with a flashlight but I can't find it. (small rant) Damn loose things.... Anyway... I have some 3/16 brass bar stock and I'm wondering if it would cause problems if I replaced one or both of the pins with new pins I made from this? I'm a little worried that the softer metal might warp or bend in the receiver and be a pain to remove. Though I don't really know if they have much stress on them as mainly all they do is hold the trigger group in place.
