Just bought a 20" AR .308 rifle length barrel to replace a 16" intermediate length I had on. This gas tube doesn't go half way like the intermediate tube did. Is this still acceptable? This is the rifle length gas tube
Not and expert but just from that one picture it looks good, should engage the gas key about right. Should be 15.5 inches long if it a "rifle length" gas system. Though there are some slight variances...Joe
Doing the right thing is not always the easiest thing. It still needs doing..
