H3 - M16 Full Auto Slide Dead Blow Buffer - 3.25" - 5.2oz
M16 Full Auto H3 Heavy Carbine Recoil Buffer AR-15 3.25"
This is a U.S.-made, 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 Triggers, where a total assembled weight of 5.1 – 5.2 oz appears to be the ideal “sweet spot” for smooth, reliable operation.
The sliding internal weight portion weighs 4.3 oz — the same as the combined sliding tungsten weights in a traditional H3 buffer. However, by using durable 8620 steel instead of tungsten, manufacturing costs are significantly lower while maintaining comparable performance. The complete buffer assembly weighs approximately 5.15 oz.

M16 Full Auto H3 Buffer
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.
