AR 15 H3 Carbine Buffer

The AR 15 H3 Carbine Buffer is the heaviest of the common carbine-tube buffers, designed for shooters who need maximum dwell time and the softest possible recoil impulse. Installing an ar 15 h3 carbine buffer adds the most internal weight in the standard buffer lineup, slowing the bolt carrier to settle heavily over-gassed, suppressed, and short-barreled rifles. You will find it among the rest of our AR-15 buffers and trigger parts.

A buffer is an ordinary rifle part. Always follow your state and local laws, and you must be of legal age and eligible to purchase.

Specifications and fitment

Maximum dwell for hard-running rifles

An H3 carries more weight than a standard or H2 buffer, so the action cycles slower and the rifle stays flatter shot to shot. That extra mass is especially useful when a suppressor or a generous gas port is pushing the bolt carrier harder than the system was tuned for. The slower carrier speed also reduces stress on the bolt carrier group and other internal components over time, the kind of durability focus that runs through the whole forced reset trigger range.

Frequently asked questions

When should I choose an H3 over an H2? Reach for an H3 when an H2 still leaves the rifle feeling violent or ejecting brass far forward, common on suppressed or short-barreled setups. If the action begins to short-stroke, step back down to a lighter buffer. Want a lighter option? Compare the H2 carbine buffer.

Does it fit a standard carbine tube? Yes. It is sized for carbine-length AR-15 buffer tubes. Confirm you are running a carbine tube before ordering.
