The Phase 5 Pistol Buffer Tube Foam Pad (brand part no. PBT-FP) slips over a 1.25 in. AR-15 pistol buffer tube to add cushion and a more comfortable cheek or shoulder reference point. It’s built from Nitrile, a durable material with good abrasion resistance and high tensile strength, wrapped around NPVC foam that resists oils, fuels, ozone, and UV light instead of breaking down after a season of range use. Measuring 3.5 in., it’s sized to cover a meaningful section of a pistol buffer tube without interfering with brace or arm-strap hardware. It’s a simple, low-cost way to make a bare pistol tube more comfortable to shoulder or brace against.
