Can't beat inconel! - V Seven Extreme Environment Gas Tube

I've tried just about every gas tube available. The fitment for a standard tube vs this aftermarket aren't completely universal depending on your gas block. Out of the 8 different gas blocks I tried, all were a great fit. The only downside to this gas tube is the gas tube is designed to fail first in an overheating situation to prevent a gas block fatal failure. This gas tube will outlast most barrels and gas blocks. It is lighter, beefier than a standard tube. It isn't necessary but definitely adds to your lightweight or shtf build. I wanted the most durable materials for my build. With this, I have it. Good luck finding a better gas tube.
