Silent operation. Adjustable spring tension. H2 weight for forced reset trigger and Super Safety compatibility. Lifetime warranty. 100% USA made — all for $59.99. This is the perfect blend of engineering and value for any AR-15 build running a forced reset trigger, Super Safety, or drop-in FRT system. You get the heavy buffer weight your FRT demands, silent captured spring operation that eliminates buffer tube rattle and spring noise, and full adjustability — in one drop-in unit that costs the same as a standard buffer. $59.99 · H2 Heavy Weight · Silent Captured System · Lifetime Warranty · 100% USA Made FRT & Super Safety Compatible: The SMB Gen3 H2 meets the H2 minimum weight threshold (4.7 oz equivalent) required for reliable operation with forced reset triggers and Super Safeties on AR-15 platforms. Works with the Partisan Disruptor FRT, AS Designs ARC-Fire V2, Hoffman Tactical Super Safety, and any other drop-in forced reset system on a standard AR-15 platform.

On a normal AR-15 running a standard mil-spec trigger, that noise is just background — annoying but inconsequential. On a forced reset trigger or Super Safety build where you're cycling at significantly higher rates of fire, that rattle compounds with every cycle, the tube heats up faster, and spring fatigue comes earlier. The SMB Gen3 eliminates that entirely. The polymer guide rod keeps the spring centered and off the tube wall throughout the entire cycling stroke — forward and rearward. Quieter operation, less heat transfer to the tube, and a spring that maintains consistent tension longer because it's not being abraded against a steel tube on every cycle. You get all of that plus the H2 heavy weight your forced reset trigger or Super Safety requires — at the price of a standard buffer. There is no better value in an AR-15 FRT buffer at $59.99. Running a suppressed build or a carbine under 16"? Consider stepping up to the SMB Gen3 H3 — the additional weight helps manage the increased gas volume and faster cycling that suppressed or short-gas builds generate with a forced reset trigger. Installation Insert polymer base with guide rod into the buffer tube Insert the spring onto the guide rod Insert the buffer over the spring No tools required. Drop-in replacement for any standard AR-15 carbine buffer tube setup.
