JE Machine Tech PS-BTP4 Buffer Tube Features The Je Machine Tech PS-BTP4 is machined from 6061 aluminum a lightweight alloy that keeps the tube s weight down without compromising the strength needed for reliable buffer cycling. Fourteen individual pass through cuts run the length of the tube removing material precisely where it is not structurally needed. A full length fluted underchannel further reduces mass while maintaining a smooth surface for the buffer spring assembly to operate against. The Type II hard anodized finish protects the aluminum from corrosion and wear during regular use and handling. At only 3.20 ounces the PS-BTP4 is built for shooters who measure every gram in their AR pistol build shaving weight from a component that is often overlooked. Its 7.19 inch length with a 1 inch inner and 1.24 inch outer diameter matches standard AR pistol buffer tube dimensions simplifying compatibility with common buffer springs and braces. The black finish keeps the tube s appearance consistent with most factory AR-15 finishes. This buffer tube is a solid choice for anyone building a lightweight AR pistol focused on minimizing overall weight.
