XTS Buffer Tube Complete Assembly Features The XTS Buffer Tube Complete Assembly brings every component needed for a buffer system installation into a single kit including the mil spec buffer tube buffer buffer spring castle nut and end plate. That completeness means a builder does not need to track down individual parts from multiple sources to finish a lower receiver build. Robust construction throughout the kit is built to handle the repeated impact and cycling that a buffer system experiences during normal rifle operation. Because the kit follows mil spec dimensions it is compatible with the wide range of stocks and lower parts kits built to that same standard. This assembly simplifies what can otherwise be a frustrating step in an AR-15 build since sourcing a matched buffer spring tube castle nut and end plate separately often leads to fitment issues. Finished entirely in black the assembly blends seamlessly with nearly any AR-15 build regardless of other component colors. Whether assembling a rifle from scratch or replacing a worn or damaged buffer system this kit provides everything needed for a smooth reliable installation. For builders who want a dependable complete solution in one box the XTS Buffer Tube Complete Assembly is a practical choice.
