WMD Guns Mid-Length Gas Tube AR-15 AR-308 Nitromet Black 11.75"

The WMD Guns Mid-Length Gas Tube is a replacement gas tube for AR-15 and AR-308 mid-length gas systems. It directs gas from the gas port back to the bolt carrier to cycle the action, and it is sized at 11.75 inches for mid-length systems.

The tube is made from 304 stainless steel, which resists corrosion under repeated heat cycling. It is finished with the Nitromet salt bath nitrocarburizing process, which the input describes as producing a surface hardness of Rc 55 and a matte black finish that matches other Nitromet-treated AR components.

The tube is a direct fit for AR-15 and AR-308 platforms and ships with the roll pin needed for installation. It is intended for builders replacing a damaged or discolored factory tube or refreshing a mid-length upper.
