Hey guys, was wondering if any one would happen to know if a gas piston kit (i dont know which one if any) would fit on this new upper im thinking of getting. Its a colt Hbar 1:7 5.56 nato. I was only gonna get it if i could fit a gas piston kit on it but thought it might not since its a Hbar and the barrel is rather larger/thicker then standard barrels. Any info would be very appreciated.

From what I have seen , the current kits are only for the M4 carbines and you would have to Measure your barrel for the gas block...There is one kit for the .750 Barrel (3/4 inch) and one for the .875 (7/8 inch barrel) that is 100 bucks more !
Brownells carries them both.
