Everybody machines their BCG with an integral impact shoulder now. Dare I say...its standardized for the most part?
Can you mix and match piston parts from different manufacturers? Hey I said I have a piston LWRC, bought to see the hoopla, I didnt see any. If I want a piston again in 223/556 it will be a SCAR or ACR or XCR.
