AR15/M4 Carbine Recoil Buffer – H3 (5.5 oz.)

Description

The Revolution Flex AR15 H3 Recoil Buffer 5.5 oz is a heavyweight, mil-spec replacement carbine buffer designed to optimize the operating system of AR15 and M4 platform rifles. Engineered for over-gassed systems, suppressed rifles, and SBR builds, this H3 mass increases dwell time and reduces bolt carrier velocity for smoother cycling and less felt recoil.

Why Upgrade to H3 Weight?

Standard carbine buffers (3.0 oz) are often too light for modern carbine-length gas systems. The Revolution Flex AR15 H3 Recoil Buffer 5.5 oz configuration adds critical reciprocating mass to correct over-gassing, reduce bolt bounce, and improve extraction timing without changing your gas block.

Technical Specifications:

• Model: BFE H3 Carbine Recoil Buffer
• Total Weight: 5.5 oz / 156g
• Internal Configuration: 3x Tungsten Weights for consistent inertial mass
• Body Material: 6061-T6 Aluminum Body with Hardened Steel Face
• Finish: QPQ / Anodized Corrosion-Resistant Coating
• Overall Length: 3.25″ Standard Carbine Buffer Length
• Compatibility: Mil-Spec AR15 / M4 Carbine Receiver Extension & Carbine Spring

Key Performance Benefits:

• Recoil Mitigation & Muzzle Control: Increased mass reduces felt recoil impulse compared to a standard carbine buffer, keeping sights on target for faster follow-up shots.
• Optimized Cyclic Rate: Slows BCG velocity to bring rate of fire back into the optimal range for carbine systems.
• Suppressed & SBR Ready: Specifically recommended for 10.5″, 11.5″, 14.5″ barrels and for rifles running a suppressor to counteract increased back-pressure.
• Eliminates Bolt Bounce: The solid tungsten weight stack prevents bolt bounce, ensuring positive lockup and reliable feeding.
• Drop-In Installation: No gunsmithing required. Direct replacement for your standard carbine buffer.

Compatibility Note: For use in carbine buffer systems only. Not for use in A2 rifle-length systems. Verify your buffer tube is mil-spec carbine length before ordering.

Built For Demanding Setups. Ready When You Are.

When standard buffers can’t handle the gas, the Revolution Flex AR15 H3 Recoil Buffer 5.5 oz delivers. As the go-to heavy buffer for suppressed, SBR, and over-gassed carbine systems, it provides maximum mass for the smoothest cycling, softest recoil, and most reliable lockup.

If you run a suppressor, a short barrel, or a hard-use carbine, the H3 is the upgrade that brings your rifle back into spec.
