SureFire Introduces The Quietest .30 Caliber Suppressor On The Market


Fountain Valley, CA — SureFire, LLC, manufacturer of high-performance illumination tools, suppressors, and tactical products, has begun accepting orders for the latest model in its high-performance line of SOCOM Fast-Attach® sound suppressors. The new SOCOM300-SPS is the quietest suppressor ever built for 300 Black Out (subsonic and supersonic), .308 and 300 Win Mag. This versatile suppressor is also very effective in suppressing the 5.56mm cartridge.


The SOCOM300-SPS owes its sound-suppressing prowess to highly specialized baffles creating a longer dwell time within the suppressor and achieving unprecedented levels of sound attenuation. The suppressor is constructed of Inconel, an advanced high-temperature alloy, and stainless steel, and it typically adds only 6 inches to the length of a weapon. Computer-controlled welding enhances the suppressor’s overall durability, as does a corrosion-resistant coating of Ionbond DLC and Cerakote™ ceramic finish. In fact, the SOCOM300 SPS, like all SureFire SOCOM Series suppressors, is durable enough for full time use and designed to typically outlast the weapon barrel to which it attaches.


A precision indexing system ensures that the suppressor mounts to a compatible SureFire SOCOM series adapter—which also serves as a high-performance muzzle brake or flash hider when the weapon is unsuppressed—securely and with perfect alignment every time. This patented no-tools Fast-Attach system also makes the suppressor easy to remove after extended firing because the index tab is located in a low-carbon-buildup area. Like all SureFire SOCOM suppressors, the SOCOM300-SPS produces minimal and consistent point-of-impact shift compared with the unsuppressed weapon, regardless of the number of times the suppressor is attached and detached to and from the weapon.


The SOCOM300-SPS suppressor is available in two colors—Black and Dark Earth—and has an MSRP of $1075. It is available for purchase in states that allow suppressor ownership through authorized SureFire suppressor dealers. For complete product information visit:

    Any update on when the warcomps might be released?

    Quietest ever — but we won’t post the actual sound reduction stats.

      Or weight. Two very important metrics for suppressor selection.

      • Mike says:

        20.3 ounces on the website.
        120 DB with .300 BLK Subsonic

        • Mike D says:

          I’m curious as to what information they are using to deem this the “Quietest .30 Caliber Suppressor On The Market”. I don’t see any decibel ratings listed on their page, so I’m not sure where the 120 came from. If that is true, the Omega lists an average dB rating of 119.5 for 300 BLK. Whose is quieter?

            An industry professional posted the following numbers on M4C
            5.56 16″ mk262 134dB
            300 10″ 208gr 120dB
            .308 24″ 175gr SMK 129 dB
            300WM 16″ mk248 137dB

              And Silencerco Omega pushes the 556 out at 130.1 dB and weighs 14 ounces.

              Its worth noting that the SF can does beat the Omega in the 308 category by about 4db but at 6 extra ounces of weight..not sure its really worth it.

              Does anyone have data on the 300WM on the Omega to compare against the SF?
