So I just finished putting together an 18" rifle. It has a mill spec fire control group, full auto bolt and H2 buffer from PSA. I got a full metal Kabuto mini kit. I made sure to clearance the Kabuto lever and leg so that it would cycle in regular semi and FRT. It function tested fine and was resetting. I took it to the range and ran about half a mag of regular semi and opened it up to find the lever had snapped. Aside from some carnage glitter there doesn't appear to be any damage to any other parts. The only thing I can think of is I shaved the lever too thin, but I tried not to shave it any thinner than it needed to not lock the bolt. I have a metal super safety on the way and would like to not snap it's lever.
