SureFire Says New Model is Quietest 30-Caliber Suppressor

By Woody published on in News

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.

    Can this can be used on a 9mm smg and can it be disassembled for cleaning and maintenance?

      No. 9mm is too large (.355) for a can designed for 7.62 (.30) projectiles

    CTD,
    If I purchased ammunition from cheaper than dirt and pay the shipping, will you send it to me direct or do I have to go through a retail Store?

      JIMO, seriously, call their 800 number instead of using a topic forum. This has got to be a prank, right? I haven’t seen anyone ask random customer service questions on topic forums in the 2+ years I’ve been on here.

    Sweet can. I’m having a hard time thinking of a reason why I would want or need to put one on a .300 Win. Mag.

      Sound displacement. A canned .300 WinMag sounds much further away than it is. This helps in taking all sorts of game, especially the kind that shoot back.

    I’d like to buy one for my DPMS AR-10 if it’s as quiet as the one on the video. But I’m concerned that a subsonic blackout round may be quite a bit different than a normal .308 round?? Does anyone know from experience? I’ve never bought a suppressor, never shot with one, but this video is getting me excited.

      ss1. I have used a can on .223/5.56, 300 BLK and .308/7.62×51. You will not get the same results from these calibers. All in all, and especially if you reload, the 300 Blackout provides the average Joe like me a very reliable semi-auto suppressed .30 cal platform. I lie to fire my Rem 700 in .308 suppressed, along with my SCAR 17S. They are very different but very fun to shoot steel with a can. My suggestion is to consider the multi-cal cans such as an AAC 762-SDN-6 or comparable. You can own three cans. One for .22 rimfire, preferably stainless steel and user serviceable. That one will cover ,22LR, .22 Short, 22WMR, .22WinMag, 5.7, and I think that’s it. Then get a can that covers from 9mm to .45ACP. Then a rifle can that covers .223/5.56 up thru .308/7.62×51. Three cans and you can cover many different weapons. Have fun!

      Does Cheaper than dirt sell these suppressors? Ones for 9mm to 45 ACP’s

      @Rich:

      Thanks for explaining from your perspective. It sounds like suppressors are a big part of your gun hobby.

      Basically I was impressed by the video, but that’s some serious money for a suppressor, and if my AR-10 would be louder then I’m probably not interested. But I may call the SureFire company just to get their take on it.

    Thank you for the information on AR 15 gear suppressors.

    If it can shoot 7.62×51 it can surely shoot 7.62X39 right?

      @ Sean.

      Only if the threading is a 5/8×24-inch…

      Hey Sean: I’ll contact SureFire and send them the link to the story. Perhaps I can persuade them to monitor comments.

      But, yes, the 30-cal suppressor should also suppress 7.62×39. As Secundius notes, the issue will be whether your AK-style rifle (I’m guessing) muzzle has the right thread pattern, and if your existing flash suppressor is fixed or removable. It might require an adapter for the suppressor. That’s why I’ll urge SureFire to come on and answer FAQs with more authority, since CTD doesn’t sell suppressors.

      Regards, Woody

      That would be great Woody, or even if they made adapters for the normal 14x1LH for many small diameter barrel AK’s and 24×1.5 RH threading for AK 74 type threading like what is on my SGL 21.
