I have a 20" Monster barrel with a Superlative Arms gas block. Is it normal for a little gas to leak by where the gas tube comes out? It's not a large amount, a thin line at about 2 o'clock from the rear POV, and maybe a 1/4" long.
My only experience is with 300BLK pistols and I don't think they generate anywhere near the pressure this does (even with the supers) so it's not really a fair comparison. That and the barrels and gas blocks are both black but even rubbing a finger on them doesn't catch any gas residue. I had some gas issues after I first built the 6ARC and double checked alignment and pin, all seems to be centered and lined up right. Is this a normal thing to have some leakage? I have been running unsuppressed in restricted mode rather than blowby/bypass mode. Would bypassing help with the leakage at the gas tube-gas block interface?
