Description
The PWS Enhanced Steel Body Buffer H2 is built with a smarter design that actually performs. Unlike basic buffers, the fluted steel construction creates minimum contact points inside the tube, which means less friction slowing you down and debris clearing naturally instead of getting trapped. That's important if you're running hard or running dirty.
The FNC LIFE HD surface treatment is worth mentioning because it chemically bonds a protective layer onto the steel. You get corrosion resistance and cleaner cycling without needing constant maintenance. It handles carbon buildup way better than standard buffers, so your gun stays reliable over time.
What Makes This Buffer Different
At 4.4 ounces, the H2 weight is the real workhorse for modern AR builds. It slows the bolt carrier group just enough to smooth out recoil without bogging the system down. This weight pairs well with carbine-length and mid-length gas systems, and it's especially popular for suppressed rifles where extra mass helps control that increased backpressure. If you're running a shorter barrel or an over-gassed setup, the H2 takes the violence out of the cycling while still maintaining reliability.
Standard, Reliable Performance
This buffer ships on all PWS MK1 complete lowers and rifles for a reason. It's their baseline choice because it works. PWS machined this on CNC equipment and finished it with precision. The fit and finish are noticeably better than budget alternatives, and the construction quality justifies itself over time.
Compatible with any mil-spec carbine buffer tube, 3.25 inches long, designed for standard AR-15 platforms. Drop it in and it cycles smoother than what most people expect from a buffer.

Frequently Asked Questions
What does the H2 weight do compared to a standard carbine buffer?
The H2 weighs 4.4 ounces versus the standard 3 ounces, giving you more mass to slow down the bolt carrier group. This reduces felt recoil, improves cycling control, and helps with suppressed rifles or over-gassed systems where things move too fast. The heavier weight keeps your gun running smoother without sacrificing reliability.
Is this buffer compatible with my AR-15?
Yes, as long as you have a standard mil-spec carbine buffer tube, this PWS buffer drops right in. It works with any direct impingement AR-15 using carbine-length receiver extensions. If you're unsure about your tube, check that it's mil-spec diameter and length.
What does the FNC LIFE HD treatment do?
It's a chemical bonding process that builds a protective layer into the steel surface. This means better corrosion resistance, less carbon buildup sticking to the buffer, and cleaner cycling over time. You get longer-lasting performance without needing to baby the maintenance.
Why is the fluted design better than a smooth buffer?
The flutes reduce contact points between the buffer and tube, which cuts friction and helps debris clear naturally instead of getting stuck. This keeps cycling smoother and the buffer working more freely, especially if you're running hard or in dusty conditions.
