Pws Enhanced Steel Body Buffer Carbine H3$60.93
Availability: In Stock
The Primary Weapons Systems Enhanced Steel Body Buffer Carbine H4 is a heavy-duty AR-15 buffer designed specifically for suppressed rifle builds. If you're running a can on your carbine and noticing sluggish cycling or unreliable function, the H4's extra mass is engineered to slow bolt carrier velocity and optimize dwell time—critical when a suppressor adds back-pressure to your system. This is PWS's heaviest buffer offering, built for shooters who demand reliable performance under challenging conditions.
The H4 uses a fluted steel body with a unique design philosophy: minimum contact points mean less surface area for carbon and debris to accumulate. That translates to easier cleaning and more consistent performance run-to-run. The flutes also allow fouling to shed away naturally during the firing cycle, so your buffer stays cleaner longer without sacrificing reliability.
PWS applies their FNC LIFE HD treatment to the steel body, a chemically bonded lubrication that's already baked in. You don't need to oil this buffer before installation; the treatment handles it. That means smoother cycling right out of the box and reduced friction as you run suppressed ammunition through your rifle. For hunters and range shooters running a suppressed carbine, the H4 pairs well with heavier springs and longer dwell pipes to create the predictable, soft-shooting platform suppressed rifles are known for.
| Brand | Primary Weapons Systems |
| Product | Enhanced Steel Body Buffer Carbine H4 |
| Material | 4140 Steel |
| Weight | 6.8 oz |
| Intended Use | Suppressed AR-15 carbines |
| Surface Treatment | FNC LIFE HD (chemically bonded lubrication) |
Suppressors add back-pressure to the system, which speeds up the bolt carrier cycle and can cause reliability issues or harsh recoil. The H4's extra mass slows the bolt carrier to optimize dwell time, ensuring reliable function and a softer shooting experience on your suppressed carbine.
Yes. The FNC LIFE HD treatment is chemically bonded to the steel body, so lubrication is built in. You can install it without oiling it first, though you can treat it like any standard buffer if you prefer.
The fluted body has minimum contact points, which means less surface area for carbon and debris to stick to. This design allows fouling to shed naturally during firing, making the buffer easier to clean and more resistant to buildup than solid buffers.
The H4 is designed for carbine-length systems. It's intended for suppressed AR-15 carbines; check your rifle's buffer tube compatibility before purchasing.
