XTS 1913 Fixed Buffer Tube Adaptor Features The XTS 1913 Fixed Buffer Tube Adaptor bridges the gap between a rear 1913 Picatinny rail and a standard AR-pattern buffer tube giving platforms that use a rail instead of a factory buffer tube mount a path to add one. This is especially useful on PCCs and similar compatible platforms that ship with a Picatinny rail in place of a conventional buffer tube interface. Because it is a fixed non-folding design it provides a simple and reliable mounting point without the added complexity or failure points of a folding mechanism. Once installed it accepts any standard commercial or mil-spec buffer tube opening up compatibility with a wide range of braces and stocks. Constructed from 7075 aluminum the adaptor is built to handle the repeated stress of a mounted brace or stock without flexing or wearing prematurely. Its black finish matches the vast majority of PCC and AR-pattern builds keeping the overall look consistent once installed. Installation is straightforward clamping onto the existing 1913 Picatinny rail without requiring permanent modification to the host platform. For PCC owners who want the option to run a collapsible brace or stock the XTS 1913 Fixed Buffer Tube Adaptor is a direct and dependable way to get there.
