  • The Phase 5 Hex Pistol Buffer Tube Kit comes with the following components…
    • Pistol buffer tube
    • Castle Nut
    • End Plate
    • Foam Pad


The Phase 5 buffer tube was specifically designed to be used in conjunction with the (sold separately) Sig SB15 Stabilizing Brace.  By way of the hexagonal projection on the buffer tube, the Phase 5 pistol buffer effectively increased the length of pull of the system.


The buffer tube is machined from high strength, premium 7075 T7 billet aluminum, which is strong than the 6061-aluminum used by other buffer tube manufacturers. 


This kit includes a foam pad that can be used to cover the end of the buffer tube.  This foam padding allows you to have a comfortable cheek weld position to more comfortably and accurate engage targets with your AR pistol.
