Phase 5 Hex-2 Pistol Buffer Tube

The Phase 5 Hex-2™ is our newest AR type Buffer Tube. This tube has been specifically designed to utilize the Sig Sauer™ SB15 Pistol Stabilizing Brace. The Hex-2™ is a heavy duty USA certified 7075 T7 billet aluminum buffer tube with the versatility to use the Phase 5 nitrile Foam Pad (included) or the SB15 Pistol Stabilizing brace (sold separately).

Working closely with Sig Sauer™ the Phase 5 Hex-2™ was a special project that involved a number of firearms instructors, law enforcement professionals and AR Pistol enthusiasts alike. While asking questions along the way and updating the design based on the recommendations given by all; the Hex-2™ has become the perfect component for any AR pistol build.

The Hex-2™ even in its most basic package includes a castle nut, end plate and foam pad.
