The Primary Weapons Systems Enhanced Steel Body Buffer is a .308 short buffer purpose-built for AR-10 platforms running standard buffer tubes. PWS designed this H2-weight carbine buffer with a fluted 4140 steel body that minimizes contact points throughout the cycling stroke — the benefit is twofold: debris sheds away instead of collecting in the buffer, and a chemically bonded lubrication coating keeps things moving smooth cycle after cycle. At 4.4 oz, it's the drop-in solution for shooters wanting cleaner function and easier maintenance on their .308 semi-auto rifle.
If you're running an AR-10 with a standard buffer tube and feeding it .308 Winchester ammunition, this buffer replaces the full-length carbine equivalent without requiring adapter tubes or lower receiver modifications. The shortened profile is the key: it plays nice with AR-10 geometry where a standard AR-15 buffer would be too long. This is the same buffer that ships with PWS MK2 series complete lower receivers and rifles, so it's proven in factory builds.
The fluted design and chemically treated finish aren't cosmetic touches — they directly improve reliability and reduce maintenance intervals. Debris that would otherwise foul a traditional solid buffer gets pushed out with each shot, and the enhanced lubrication coating means less wear on the buffer itself and smoother interaction with the bolt carrier group. For long range, precision, or high-volume shooting days, that translates to fewer stoppages and easier cleaning afterward.
| Weight | 4.4 oz |
| Material | 4140 Steel |
| Caliber | .308 Winchester |
| Buffer Class | H2 Carbine |
| Platform Compatibility | AR-10 with standard buffer tube |
| Finish | Chemically bonded lubrication coating |
Yes — it's designed for AR-10 platforms using standard buffer tubes. The shortened profile is essential for proper AR-10 geometry. Do not use this on an AR-15; the H2 weight and length are specific to .308 rifles.
The fluted geometry and minimum contact points allow carbon and debris to escape during operation instead of accumulating inside the buffer. This reduces fouling and makes cleaning easier between shooting sessions.
This buffer is designed to work with AR-10 lowers using standard buffer tubes. It ships on PWS MK2 series complete lowers and rifles, so if your lower accepts a standard carbine buffer tube, this will fit.
The H2 weight (4.4 oz) is optimized for .308 Winchester cycling. Buffer weight affects bolt carrier group velocity and recoil impulse; this weight class ensures reliable function with .308 loads and standard AR-10 springs. Lighter or heavier buffers may cause unreliable feeding or ejection.
