Primary Weapons Systems Ar 308 Enhanced Buffer Steel Body Carbine H2 Black

The Primary Weapons Systems AR .308 Enhanced Buffer is a purpose-built recoil management component for AR-10 platforms and .308 short-action rifle builds. This H2-weight steel buffer weighs 4.4 oz and ships standard on PWS MK2 series complete lowers and rifles, making it a proven choice for shooters who want factory-tuned performance in their modern sporting rifles or custom builds.

PWS engineered this buffer with a fluted steel body design that minimizes contact points inside the tube—a smart detail that lets fouling and debris pass through instead of accumulating in critical areas. The 4140 steel construction receives a chemically bonded lubrication coating that reduces friction and promotes smoother, more reliable cycling across a wide range of ammunition. The shortened profile fits standard AR-10 buffer tubes, so it integrates cleanly into existing setups without requiring proprietary hardware.

Whether you're assembling a precision .308 AR, running a duty rifle, or dialing in a long-range platform, this enhanced buffer absorbs recoil impulse while keeping your action running clean. The H2 weight suits heavier-recoiling loads and provides the cushioning needed for sustained accuracy and shooter control.

Frequently Asked Questions

Will this buffer work on my AR-10 build?

Yes. The PWS Enhanced Buffer is designed for AR-10 platforms using standard buffer tubes. Its shortened profile fits without modification.

What's the difference between this buffer and lighter options?

This is an H2-weight buffer at 4.4 oz, which provides more recoil cushioning and is suited for heavier-recoiling .308 loads. Lighter buffers cycle faster but may not manage recoil as effectively in hard-kicking calibers.

Does this buffer come standard on PWS rifles?

Yes. This enhanced buffer ships standard with PWS MK2 series complete lowers and finished rifles, so you can trust it's a purpose-matched component for those platforms.

What does the fluted design do?

The fluted body reduces contact points inside the buffer tube, allowing powder debris and fouling to pass through more easily rather than accumulating and creating binding points. Combined with the lubrication coating, this promotes reliable, smooth cycling.
