The LBE Unlimited ARBUFF-H3 is a heavy carbine-length buffer designed to fine-tune the cycling of AR-15/M16 platforms. It is particularly effective for rifles that are "over-gassed," suppressed, or have short-barrel configurations (SBRs). These buffer are also very useful for weapons that are using FRTs or Super Safeties.

Why Use an H3 Buffer?
The H3 is the heaviest standard carbine buffer. By increasing the mass of the reciprocating assembly, it provides several performance benefits:
- Reduced Recoil: The extra weight slows down the bolt carrier group (BCG) and absorbs more energy, leading to a softer "felt" recoil.
- Slower Cyclic Rate: Essential for full-auto or fast-firing scenarios to prevent malfunctions and "bolt bounce."
- Improved Extraction: By delaying the opening of the bolt, the casing has a millisecond longer to contract, making extraction smoother and more reliable in high-pressure setups.
- Suppression: If you run a suppressor, the backpressure increases gas port pressure; an H3 buffer helps counteract this "over-gassed" condition.
