Primary Weapons Systems
The Primary Weapons Systems Enhanced Steel Body Buffer H3 is a precision-engineered buffer designed to fine-tune your AR-pattern rifle's recoil impulse and cycling characteristics. At 5.5 ounces, the H3 weight sits in the middle of PWS's buffer lineup, making it a versatile choice for shooters running standard-pressure loads who want smoother operation without over-dampening. Whether you're building a reliable duty rifle, a competition platform, or an all-around hunting AR, the right buffer weight matters—and PWS has engineered this one with real thought.
What sets the Enhanced Steel Body Buffer apart is its fluted design and construction philosophy. The unique fluting pattern minimizes contact points inside your buffer tube, which means dirt, fouling, and debris can migrate through rather than accumulating and gumming up your action. That's especially valuable if you're shooting suppressed, running heavy round counts at the range, or operating in less-than-ideal field conditions. The steel body is treated with PWS's FNC LIFE HD coating—a chemical bond process that locks in lubrication rather than relying on surface oils that wash away or dry up. The result is faster, more consistent cycling with less maintenance burden.
The H3 weight is the baseline choice for standard ammunition and typical barrel lengths. If you're running a suppressor or heavier loads and want maximum dampening, PWS offers the H4; if you prefer lighter recoil impulse, the H2 is available. This is a drop-in replacement for any AR-15 or AR-pattern rifle using a standard receiver extension (buffer tube).
| Brand | Primary Weapons Systems |
| Model | Enhanced Steel Body Buffer H3 |
| Weight | 5.5 oz |
| Material | 4140 Steel with FNC LIFE HD coating |
| Compatibility | AR-15 and AR-pattern rifles with standard receiver extension |
| Part Number | 5PWCBH3-1F |
PWS offers three weights in the Enhanced Steel Body line. The H2 is the lightest at 4.4oz and reduces recoil impulse for faster splits and softer shooting impulse. The H3 at 5.5oz is the middle ground, suited for standard loads and most AR builds. The H4 at 6.8oz is the heaviest and is intended for suppressed rifles, where it provides additional dampening to manage the slower bolt velocity that suppressors induce.
Yes, the H3 is a drop-in replacement for any AR-15 or AR-pattern rifle that uses a standard receiver extension (buffer tube). Simply remove your existing buffer and spring, slide in the new H3, and reassemble. No modifications or special tools required.
FNC LIFE HD is a chemical treatment that bonds lubrication directly to the steel surface. This keeps your buffer cycling smoothly longer, reduces the need for frequent re-oiling, and provides better performance in dirty or suppressed environments where standard surface lubrication tends to dry up or wash away quickly.
The H3 will function with a suppressor, but PWS specifically recommends the heavier H4 for suppressed use. Suppressors slow bolt velocity, and the H4's additional weight helps manage that slower cycling for optimal reliability and control.
