The Guntec AR15 Pistol Buffer Tube Kit provides everything you need for a complete AR pistol build or upgrade. This kit is engineered to deliver reliable performance in compact AR platforms.
This buffer tube kit cycles reliably across a wide range of AR15 pistol configurations. The matched components work together to provide consistent bolt carrier group movement and reliable feeding and extraction.
Installation is straightforward for those familiar with AR15 assembly. The tube threads directly onto your lower receiver, and the spring and buffer assemble inside the tube. Proper staking of the castle nut is recommended for security.
