SureFire, LLC claims its new SOCOM300-SPS is the quietest suppressor ever built for .300 Blackout (subsonic and supersonic), .308 Winchester and .300 Win. Mag. MSRP is $1075.
Thomas Carlson, director of public relations for SureFire, said sound data averages for various rounds were: .300 Blackout subsonic, 120dB; 7.62×51, 129dB; .300 WM, 137dB; and 5.56 NATO, 134dB.
For the 120dB .300 AAC Blackout subsonic results in the accompanying video, the rifle’s barrel length was 9 inches, and the round was Hornady’s 208-grain .300 Blackout subsonic load.
“We use the B&K Pulse system” to collect the average DB levels, Carlson said. “We have the most advanced sound-metering system in the industry. We follow mil-spec standards, but do three 10-round samples” to collect data for the averages, he added.
The SOCOM300-SPS is the latest model in the SureFire line of SOCOM Fast-Attach sound suppressors. The body is made of Inconel, a high-temperature alloy, and stainless steel, and it typically adds only 6 inches to the length of a rifle.
An indexing system ensures that the suppressor mounts to a compatible SureFire SOCOM series adapter that also serves as a muzzle brake or flash hider when the weapon is unsuppressed. The no-tools Fast-Attach system makes the suppressor easy to remove and install.
The SOCOM300-SPS suppressor is available in Black and Dark Earth colors and is available for purchase in states that allow suppressor ownership. Cheaper Than Dirt! does not sell Class 3 firearms or accessories, but check our list of affiliated FFLs to find an NFA-qualified retailer near you.
