If you're out to build the perfect AR pistol, why settle for a sub-par buffer tube? Phase 5 Tactical makes one of the finest on the market. Precision machined out of aluminum, this tube is tough enough to handle the recoil of your AR pistol. The tube is also put through a Mil-Spec hard coat anodizing process to protect it from scuffs, scratches, wear, and corrosion.

A lower slot machined into the tube ensures that all Mil-Spec end plates and sling mounts will fit perfectly. The included castle nut holds this tube securely in place; it won't come loose on you no matter how frequently or rapidly you fire your AR pistol!
