The PREFERRED Buffer we use in Forced Reset Device Applications!

M16 Full Auto H3 Heavy Carbine Recoil Buffer AR-15 3.25"

Using "Old School" time tested M16 Full Auto logic, the market has reinvented this buffer, specifically for Forced Reset Applications!

This is a Made in Kentucky, two-piece H3 sliding-weight carbine buffer for the AR-15 platform, measuring the standard 3.25″ in length.

It features a solid steel rear section that functions as a dead-blow hammer, striking the bolt carrier group to effectively reduce or eliminate bolt bounce. The buffer was specifically engineered for reliable performance in full-auto and Forced Reset setups.

For the dead-blow mechanism to work properly, a small gap of 1/16″ to 1/8″ must exist between the head piece and the body. This clearance is preset at the factory but can be fine-tuned if needed.

These buffers have been extensively tested across a wide range of AR-15 configurations, including builds with barrels as short as 7″. They deliver excellent results with Forced Reset Devices. By using durable 303 Stainless Steel instead of tungsten, manufacturing costs are significantly lower while maintaining comparable performance. The complete buffer assembly weighs approximately 5.40 oz and the force weight is 4.5oz.

This is for use in AR-15 Forced Reset Trigger Applications ONLY!

    Zero problems. The 303 stainless is harder hitting and runs like a supercharged sewing machine

    M16 Full Auto H3 Buffer

    Posted by Ray Byrd on Jun 2nd 2026

    The other “H3” buffers streamers recommended are absolutely garbage. One pop sallies with the normal dead blow H3’s. This buffer instantly changed the results for me and my buddies. I appreciate doing business with yall! If you contemplating buying one this is the end all be all.
