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 - 7.62x51 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.

SUREFIRE BLACKOUT SUPPRESSION

The SureFire SOCOM300-SPS was designed specifically to reduce 300 Blackout subsonic and supersonic ammo down to the quietest level possible from a precision-built suppressor.  The 300-SPS boasts the most (at the muzzle) decibel reduction of any SureFire suppressor to date.  In addition to Blackout, it's also rated up to 300 Winchester Magnum and can handle any centerfire cartridge below that.  The 300-SPS has the same features that have awarded SureFire many US Special Operations Command (SOCOM) victories and military contracts.  The specialized V-shaped baffle design promotes extreme decibel reduction and eliminates flash and dust signatures.  

Constructed of Inconel alloy and stainless steel, the SOCOM300-SPS still utilizes the patented Fast-Attach mounting system for easy installation and removal.  

Decibel Reduction

  • 120dB - .300 Blackout subsonic
  • 129dB - 7.62x51
  • 134dB - 5.56
  • 137dB - .300 WM

CAPITOL ARMORY'S OPINION

The SureFire SOCOM300-SPS is a bit of a deviation to SureFire's normal rifle-suppressor lineup.  For most of their cans, SureFire has really leaned toward ultra-low backpressure and flash suppression.  They build suppressors towards the needs of the military, not necessarily the desires of civilians.  The 300-SPS is their first rifle suppressor that meets the needs of civilians first, rather than military.  It still has excellent flash reduction, but is much quieter at the muzzle than some of their other cans.  If you've always liked SureFire but wished they had a bit more quiet at-the-muzzle suppressor, the SOCOM300-SPS is it.  


FEATURES
  • Optimized for 10" and shorter 300 Blackout barrels
  • The most quiet SureFire suppressor to date
  • Inconel and Stainless construction
  • Full-auto rated
  • Superior accuracy
  • Test fired to ensure sub 1-MOA group size and point-of-impact shift
  • Virtually no muzzle flash
