redneckmedic Posted January 31, 2011 Report Posted January 31, 2011 Everything I have found seems to say that a standard .223 gas block and gas tube will work for a .308, Does anyone have any information to back that up or bust it?
TacBlade Posted January 31, 2011 Report Posted January 31, 2011 They will work. The gas system works the same on the .223 and .308.
98Z5V Posted February 1, 2011 Report Posted February 1, 2011 Some Armalite .308s have unique gas tube lengths, though. Otherwise, if you have a .308 barrel with a rifle length gas system, it'll use the AR-15 rifle length gas tube. Barrel makers usually state what gas system their specific barrels use. Pay attention to that on the AR-10-compatible barrels.
survivalshop Posted February 1, 2011 Report Posted February 1, 2011 Just be mindfull of gas block diameters or gas block to barrel diameters, .750", .836 " ,.936 " and so forth.
