AR-15 H3 Heavy Carbine Buffer – 5.5 oz

The AR-15 H3 Heavy Carbine Buffer is a 5.5 oz buffer designed for compatible carbine-length AR-15 recoil systems requiring additional buffer mass. Featuring reciprocating shifting weights, this H3 buffer helps control bolt carrier movement and reduce the potential for bolt bounce.

The durable black nitride steel body provides wear and corrosion resistance, while the orange neoprene bumper cushions rearward movement within the buffer tube. At 5.5 oz, the H3 configuration provides substantially more mass than a standard carbine buffer and may help moderate bolt carrier velocity and felt recoil in properly configured AR platforms.

Made in the USA, this H3 carbine buffer is a durable replacement or upgrade for compatible AR-15 buffer systems.

What is the difference between an H2 and H3 buffer?

An H3 buffer is heavier than an H2 buffer and provides additional reciprocating mass within an AR-15 carbine buffer system. This Moriarti H3 buffer weighs 5.5 oz. A heavier buffer can help slow bolt carrier velocity and reduce bolt bounce in certain configurations, but heavier is not automatically better. The appropriate buffer depends on the firearm's caliber, barrel length, gas system, BCG, ammunition, and buffer spring.
