Je Machine Tech Buffer Tube Features The Je Machine Tech Buffer Tube is machined with ten recessed channels along its body a design that reduces both the tube s overall weight and the friction between the tube and the stock sliding across it. This smoother action means even Mil-Spec stocks with tight tolerances glide easily through all eight positions avoiding the grittiness some aftermarket tubes introduce. At just 3.2 ounces the tube adds minimal weight to a build while still meeting Mil-Spec dimensional standards for broad stock compatibility. The 8 position design gives shooters a wide range of length of pull adjustment to fit different body types and shooting styles. Three drain holes machined into the tube allow water to escape rather than pool inside a detail that matters for shooters operating in marine environments or wet weather conditions where moisture intrusion can affect internal buffer and spring components. A Type 3 hard anodized finish over aircraft grade aluminum gives the tube strong resistance to corrosion and wear from repeated use and environmental exposure. Built to fit both AR-15 and AR-10 platforms the buffer tube offers broad compatibility across common rifle calibers and builds. A durable well-engineered upgrade for any serious AR build the Je Machine Tech Buffer Tube is ready to install for sale at GrabAGun.
