Although many users build ARs without giving much thought to the buffer tube assembly, it deserves just as much attention as any other part.

For those who require the very best buffer tube assembly on the market, there's the HexOne AR Pistol Buffer Tube Kit from Phase 5 Tactical. Machined with the utmost precision from 7075 T7 aluminum, the buffer tube's strength is without equal. You certainly don't have to be concerned about this buffer tube denting or breaking under heavy use! The hexagonal shape of the tube sets your AR pistol apart from the rest. It is finished off with a surface tumbling procedure to give the entire piece a smooth feel.
