Neat, but after having a new BCA bolt basically dissolve on me after about 50 rounds, I wouldn’t use anything but their barrels or lowers for spare parts. (Be sure to keep a bunch of random pin sizes in stock as it might take a bit to find one that fits properly.)

Their flash suppressors are ugly and their grips are solid plastic, but they did get rid of their cheap and noisy buffers, so that’s a plus.

Novel idea, though. Pointless, but still novel.
