Primary Weapons Systems MOD2 AR-15 H4 Buffer - Carbine

The Primary Weapons Systems MOD2 H4 Buffer brings a fluted 4140 steel body design to AR-15 carbines, giving shooters smoother cycling by letting debris clear away from minimal contact points. Built with PWS's FNC LIFE HD treatment, this AR-15 buffer chemically bonds in lubrication for consistent, reliable operation.

Features:

• H4 weight class
• 6.8 oz weight
• Carbine length
• 4140 steel body
• Fluted design for debris clearance
• FNC LIFE HD treatment, chemically bonded lubrication
• Corrosion-resistant finish

The fluted body design minimizes contact points inside the buffer tube, letting debris clear more easily for smoother, more consistent cycling than a traditional solid-body buffer. The FNC LIFE HD treatment chemically bonds lubrication to the buffer's surface rather than relying on it wearing off with use, and the H4 weight class is PWS's heaviest MOD2 option, suited to piston-driven or heavily suppressed builds that need the most recoil-taming mass available in this line.

Primary Weapons Systems builds long-stroke piston AR-platform rifles and components known for their reduced fouling and reliable operation, applying that same engineering focus to the MOD2 buffer line.
