Q: I'm interested in your 308 carbine piston kit if you have one? I'm considering shorting my 12.5 ba barrel to 10.5 for a tighter entry weapon that will be suppressed.
dwell time will be shorter but I dont see this being a problem with a 308.
A: Hi Mike, we do not offer a piston conversion for the .308/AR-10/7.62x51 rifles. Our upper receivers for this caliber get additional machining specifically for our .308 piston system; therefore, other manufacturer's uppers are not compatible.
