This might be a bit of a stupid question but I'm building a Stag 10 in 6.5cm and some of the finer detailed information is hard to get definitive answers on with Google. I have my barrel and gas block ready to roll but I'm not sure on the gas tube. The barrel (24" ballistic advantage premium heavy barrel" says in the specs it's a rifle length gas system, but I've seen a lot of people talking about extended gas systems on 6.5cm barrels. My measurement from the very rear of the barrel to the gas port in inches is exactly 13 9/16. Does that sound in line with using a 15.125" rifle length gas tube? Thanks.
