Primary Weapons Systems A5 Enhanced Buffer Tube Kit Features The Primary Weapons Systems A5 Enhanced Buffer Tube Kit is a complete A5 buffer system upgrade that includes the enhanced A5 buffer tube an A5H2 buffer at 5.33 oz and a compatible spring providing everything needed to convert a compatible AR-15 to the A5 buffer system in a single purchase. The impact extruded 7075 aluminum tube maintains a mil-spec tube diameter for broad component compatibility while incorporating an extended carrier support lip that smooths bolt carrier cycling and reduces carrier tilt through the buffer stroke. Lightening cuts shave approximately 1 oz compared to standard mil-spec buffer tubes and the fluted body design aids in debris clearing for added reliability in adverse field and range conditions. The MIL-A-8625 F Type III Class 2 anodized 7075 aluminum buffer tube is finished to military specification hard anodize standards delivering superior surface hardness and corrosion resistance that holds up to hard use and field exposure without degradation. Enlarged drain holes clear water and debris from the buffer tube interior quickly preventing the accumulation of fouling or moisture that can slow cycling or cause malfunctions in demanding conditions. The A5 buffer system s longer dwell time and increased buffer travel improve reliability and reduce felt recoil particularly in short barrel rifle and pistol-configuration AR builds where standard carbine buffer systems produce excessive bolt carrier velocity.
