Description
SUREFIRE’S QUIETEST RIFLE SUPPRESSOR
The SureFire SOCOM300-SPS delivers the lowest muzzle decibel readings of any SureFire suppressor. Built specifically for .300 Blackout subsonic and supersonic ammunition, the 300-SPS reduces .300 BLK subs to 120 dB at the muzzle. It handles calibers from 5.56 up to .300 Winchester Magnum.
SureFire engineered the 300-SPS with V-shaped baffles optimized for subsonic rounds. This design eliminates first-round flash and reduces dust signatures. The oversized bore diameter decreases baffle strike probability from unstable projectiles, making it well-suited for short-barreled .300 BLK hosts with 10″ or shorter barrels.
Inconel alloy baffles and a stainless steel outer tube provide full-auto durability. CNC laser-welded construction ensures consistent performance. The patented Fast-Attach mounting system allows tool-free installation and removal on any SOCOM-compatible SureFire muzzle device.
DECIBEL REDUCTION
- 120 dB – .300 Blackout subsonic
- 129 dB – 7.62×51 NATO
- 134 dB – 5.56 NATO
- 137 dB – .300 Win Mag
CAPITOL ARMORY’S OPINION
The SOCOM300-SPS represents a shift in SureFire’s design philosophy. Most SureFire rifle suppressors prioritize ultra-low backpressure and flash suppression for military applications. The 300-SPS puts muzzle-side sound reduction first while maintaining flash suppression. If you want a SureFire suppressor that prioritizes quiet at the muzzle over low backpressure, this is it.
Note: The 300-SPS generates higher backpressure than the SOCOM762-RC2. This tradeoff enables the improved sound suppression performance. Plan accordingly if you’re running suppressed on a gas gun with an adjustable gas block.
