BUFFER WEIGHT

PWS H2, H3, H4 Carbine Buffer Weights

When reliability and hard-use durability matter, Primary Weapons Systems (PWS) H2, H3, and H4 carbine buffer weights are our top choice. These buffers are engineered for shooters who run their rifles in real-world conditions — not just at the bench.

Each buffer weight features precision-machined cuts that help shed dirt and debris, keeping your system cleaner and running smoother, even in harsh environments.

Available Buffer Weights:

• H2: 4.4 oz

• H3: 5.1 oz

• H4: 6.8 oz

Why We Recommend PWS Buffers:

• Superior Performance: Smooths out recoil impulse for more controllable follow-up shots and enhanced reliability.

• Debris-Shedding Design: Machined cuts prevent grit and fouling from compromising function.

• Hard-Use Durability: Built to withstand serious use and harsh conditions without skipping a beat.

Choosing the Right Buffer for Your Build:
For 6.5 Grendel, 6 ARC, or .22 ARC builds, we strongly recommend keeping multiple buffer weights on hand. This makes fine-tuning your rifle easy and lets you quickly adjust cycling without tools — especially helpful when running suppressors or testing different ammo loads.

• Non-suppressed or flow-through suppressors: Start with H2 or H3.

• Traditional baffled suppressors: H3 or H4 are often the best starting point.

Remember: tuning recoil impulse isn’t just about feel — it affects bolt life and overall reliability. A properly weighted buffer helps control cycling forces and reduces bolt stress, extending the life of your rifle.

Upgrade your AR’s recoil system and run it with confidence using the PWS H2, H3, and H4 buffer weights.

A5 H2

A5H2 Weight: 5.33 oz. The A5 buffer system is on of the most beneficial upgrades to the AR platform. When used in conjuction with an A5 length buffer tube, the A5 buffer increased reliability, accuracy, and performance of AR style firearms... especially in short barrel rifle and "pistol" configurations.

Important: A5 buffers are only compatible with other A5 buffer system components. The buffers themselves are longer than traditional carbine buffers, and they cannot be used in standard carbine receiver extensions.

The LBE Unlimited H3 Buffer Weight is a heavy-duty buffer designed to improve reliability and smooth recoil in AR-15 rifles, particularly in suppressed, over-gassed, or short-barrel configurations.

This buffer is built for carbine-length buffer systems and features an H3 weight configuration totaling approximately 5.4 oz, helping slow bolt speed, improve extraction and ejection consistency, and reduce overall wear on internal components.

Specifications & Compatibility:

• Buffer Type: H3

• Weight: Approximately 5.4 oz

• Buffer System: AR-15 carbine-length buffer systems

• Recommended Spring Pairing: Strike Industries Flat Wire Buffer Spring

• Intended Use: Suppressed rifles, over-gassed setups, short barrels

• Country of Origin: Made in the USA

By increasing reciprocating mass, the LBE Unlimited H3 Buffer Weight delivers smoother cycling and more consistent performance without unnecessary complexity. It’s a straightforward, effective upgrade for rifles that benefit from additional buffer weight.

The BCM MK2 MOD 1 T1 Buffer Weight is part of Bravo Company’s MK2 Recoil Mitigation System, designed to improve reliability, reduce felt recoil, and enhance overall cycling characteristics in AR-platform rifles.

This buffer uses a T1 weight configuration (approximately 4.6 oz) and is intended for use with A5-length / BCM MK2 receiver extensions, offering a smoother recoil impulse compared to standard carbine buffer systems. The added mass and extended system length help slow bolt velocity, improve extraction timing, and increase reliability—especially in hard-use or duty-oriented rifles.

Specifications & Compatibility:

• Buffer Type: T1

• Weight: Approximately 4.6 oz

• Buffer System Compatibility: A5-length / BCM MK2 receiver extension systems

• Recommended Spring Pairing: BCM MK2 action spring or Sprinco Green

• Function Benefits:

  • Smoother recoil impulse

  • Improved bolt speed control

  • Enhanced extraction and ejection consistency

• Country of Origin: Made in the USA

The BCM MK2 MOD 1 T1 Buffer Weight is an excellent choice for shooters looking to step up from standard carbine systems to a more refined, reliable recoil system without unnecessary complexity. It’s a proven solution for rifles that prioritize smooth operation and long-term durability.
