Primary Weapons PWS Enhanced Steel Body Buffer H2 4.1oz - 5PWSCB30-1F

The Primary Weapons Systems Enhanced Steel Body Buffer H2 is a purpose-built AR-10 buffer designed for shooters running .308 platforms who want smoother, more reliable cycling. This 4.1oz buffer works with standard buffer tubes on AR-10 builds and comes equipped on PWS MK2 series complete lowers and rifles as original equipment. The H2 weight sits in a sweet spot for .308 applications—heavier than H1 but lighter than H3—making it a solid choice if you're tuning your AR-10 for consistent performance across different ammunition types and loads.

What sets the PWS Enhanced Buffer apart is its engineering. The fluted steel body design minimizes contact points inside the tube, which means dirt, carbon, and debris can clear away instead of building up and gumming up your action. That's real-world reliability thinking. The body itself gets a chemically bonded lubrication coating that reduces friction during the bolt carrier cycle, translating to smoother function and easier cleanup between range sessions.

Built from 4140 steel and finished to PWS standards, this buffer is made to handle the demands of precision .308 shooting, whether you're zeroing loads at the range, hunting at distance, or running drills. Drop it into your AR-10 upper and lower assembly, and you've got a proven component that ships as standard on PWS rifles for good reason.

Frequently Asked Questions

Will this buffer work with my AR-10 build?

Yes, the PWS Enhanced Steel Body Buffer H2 is designed for AR-10 platforms and works with standard buffer tubes. It's the factory buffer on PWS MK2 series complete lowers and rifles.

What makes the H2 weight different from other buffers?

The 4.1oz H2 weight is engineered for .308 AR-10 applications. It's heavier than an H1 but lighter than an H3, providing a balanced cycling profile across various .308 loads and ammunition types.

How does the fluted design help with reliability?

The fluted steel body minimizes contact points inside the buffer tube, allowing dirt, carbon, and debris to clear away rather than accumulate. Combined with the chemically bonded lubrication coating, this means smoother operation and easier maintenance.
