Je Machine Tech Buffer Tube Kit Features The Je Machine Tech Buffer Tube Kit is built around a mil-spec buffer tube machined from 6061 aluminum the same aerospace grade material trusted across the AR platform for its strength to weight ratio. An anodized black finish protects the tube from corrosion and wear while matching the rest of a standard black builds hardware. At 7.15 inches long and only 3 ounces the tube adds minimal weight to the rear of the rifle while providing a solid mounting surface for a mil-spec stock. This combo kit is compatible with DPMS pattern AR platforms making it a straightforward upgrade or repair part for builders working on that system. Rounding out the five piece kit are the matching buffer spring black buffer castle nut and a standard receiver end plate so there is no need to source each part separately. Having every component arrive together saves builders time and ensures proper fitment between the tube spring and buffer weight. The standard end plate also provides a mounting point for a single point sling attachment. Manufactured in the USA this kit is a practical affordable way to finish out a stock assembly on a DPMS platform rifle build.
