Needless to say, I will not make that mistake twice. Anybody want to buy a Bushmaster carbine upper? haha
Ask your buddy if the key broke from the front or if the rear of the key hit the lower receiver. It seems there are some short buffers that allow the key to contact the lower receiver.
If the bumper is made too short or gets pounded into the buffer body
the rear of the key can strike the lower.
