Primary Weapons Systems Ar-15 Enhanced Buffer Steel Body Carbine H2 Black

The Primary Weapons Systems AR-15 Enhanced Buffer Steel Body Carbine H2 is a purpose-built AR buffer designed to fine-tune your rifle's cycling reliability and longevity. The H2 weight (4.4 oz) strikes a practical middle ground for standard-velocity ammunition and most shooting applications, making it a solid choice for hunters, competition shooters, and range builders who want to dial in their AR without going to heavier weights. PWS engineered these buffers with a fluted steel body and a minimum-contact design that lets carbon and debris shed away during operation—a smart move for guns that see heavy use or suppressed fire.

What sets the PWS Enhanced Buffer apart is the FNC LIFE HD treatment, a chemical bonding process that locks lubrication into the steel itself. That means smoother, more consistent cycling and less maintenance headache over time. You get reliability that doesn't fade as your rifle works harder, whether you're running it suppressed, unsuppressed, or pushing it through a training course. The H2 sits at the lighter end of PWS's weight range, so it'll pair well with standard buffer springs and typical carbine-length systems without over-dampening recoil or creating sluggish bolt movement.

Installation is straightforward for anyone familiar with AR disassembly—this is a direct swap into your existing receiver extension tube. If you're building a rifle from the ground up or refreshing a tired system, the H2 gives you a tuning lever that actually makes a difference in how your gun runs.

Frequently Asked Questions

What's the difference between H2, H3, and H4 buffers?

PWS offers three weights in their Enhanced Buffer line. The H2 weighs 4.4 oz and works well for standard rifle use. The H3 weighs 5.1 oz, and the H4 weighs 6.8 oz and is optimized for suppressed shooting, where the added weight helps manage the slower cyclic rate that comes with a can.

Will this buffer work with my AR-15?

Yes, if your rifle has a standard carbine-length receiver extension (buffer tube). This is a drop-in replacement; simply remove your old buffer and spring assembly and install the H2 buffer and your existing spring.

What does the FNC LIFE HD treatment do?

FNC LIFE HD chemically bonds lubrication into the steel, reducing wear and maintaining smooth cycling over extended use. It cuts down on the maintenance burden and helps your buffer stay reliable even under heavy shooting.
