The Phase 5 Pistol buffer tube is one of the best choices for your AR-15 pistol.  The receiver extension tube, itself, is machined from 7075-T6 aluminum.  This is a very high quality aluminum alloy that has excellent strength characteristics.  The tube is designed to be compatible with a mil-spec carbine buffer and buffer spring to ensure optimal reliability.

 

The Phase 5 buffer tube was specifically designed to be compatible with the Sig Stabilizing Brace (SB15).  The Phase 5 receiver extension tube has an integrated hexagonal design machined into it.  While this makes the buffer tube stand out and gives it a unique appearance, it also have another function.  The hexagonal design, when combined with the SB15 allows the stabilizing brace to have an increased standoff distance.  This can make shooting with the Sig brace easier and more ergonomic. 

 

The Phase 5 pistol buffer tube also has more advanced features.  The threading that goes into the lower receiver Is unique and different from standard buffer tube.  The threading has a slight extension and slot cut into it.  This allows the buffer tube to reach slightly further into your lower receiver.  This extension prevents carrier tilt issues by allowing the bolt carrier to be supported by the buffer tube at all times during travel.
