PWS A5 Enhanced Buffer Tube
The PWS A5 Enhanced Buffer Tube is an A5-length receiver extension designed for AR-platform builds using compatible A5 buffer system components. Constructed from impact-extruded 7075 aluminum, it combines strength, reduced weight, and enhanced carrier support in a mil-spec-diameter receiver extension.
An extended carrier support lip helps support the bolt carrier as it travels into the receiver extension, while the fluted exterior design provides additional clearance for dirt and debris. Strategic lightening cuts reduce weight by approximately one ounce compared to standard mil-spec designs without compromising the tube’s structural integrity.
The tube is finished with a MIL-A-8625F Type III Class 2 hard-coat anodizing for increased surface durability and corrosion resistance. Enlarged drain holes also help provide an exit path for water and debris during demanding use.
