AR-15 4.6oz H2 Buffer - MAR044-H2

Optimize the cycling and recoil management of your AR-15 with the AR-15 4.6oz H2 Buffer. This heavy-duty carbine buffer delivers reliable performance by increasing mass in the buffer system, helping to smooth out bolt carrier group movement and reduce felt recoil during rapid fire.

Key Features

• 4.6 oz total weight – Heavier than standard carbine buffers (typically 3 oz), providing enhanced control without over-stressing components.
• Precision-machined steel body.
• Standard carbine length of 3.25 inches to fit most collapsible stock buffer tubes.
• Durable construction designed for repeated use in 5.56 NATO and .223 Remington platforms.

Specifications

• Weight: 4.6 oz
• Length: 3.25 in
• Compatible with carbine-length buffer tubes and standard AR-15 buffer springs

Benefits for Your Build

The increased mass of an H2 buffer helps slow bolt velocity, which can minimize bolt bounce and improve overall reliability—especially useful in over-gassed systems, shorter barrels, or when running suppressors. Shooters often notice smoother cycling, reduced muzzle rise, and more consistent ejection patterns compared to lighter buffers.

Why Choose This Product

Whether you’re building a new rifle or tuning an existing one, this H2 buffer offers a straightforward upgrade for better shootability. It serves as a popular middle ground between standard carbine buffers and heavier H3 options, making it versatile for a wide range of gas system lengths and ammunition types.

Common Applications

• Mid-length and carbine gas systems
• Short-barreled rifles and pistol builds
• Suppressed firearms requiring additional mass
• General reliability tuning for competition or duty use
