SureFire Introduces .30 Caliber Suppressor, Claims It Is “Quietest On The Market”

SureFire has announced a new .30 caliber quick-detach suppressor, which they are advertising as “the quietest suppressor ever built” for the caliber. From the press release:

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 Blackout (subsonic and supersonic), .308 and 300 Win Mag. This versatile suppressor is also very effective in suppressing the 5.56 mm 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.

The suppressor market and the .300 Blackout caliber are two mutually-reinforcing entities, it seems. The more popular one gets, the more interest is generated for the other. Where this train will stop is difficult to predict, but it doesn’t seem like it’s going to slow down anytime soon.

    Makes product in state that has banned the sale and ownership of same product from civilians.

      To me that should be a huge reminder to vote with your wallet properly…

      • Patriot Gunner

        That’s true, but I wouldn’t hold it against SureFire just because they are behind enemy lines in CA. Granted I would love to see them leave and go to a gun friendly state, but that’s easy for me to say. For companies in the firearm industry a proven track record of pro 2A support is a must before they get my money.

        • echelon

          I love how this line of thinking has pervaded the “gun culture”. As if SureFire or other companies are held in place against their will…

          Sure it’s easy for us to say they should move – it should be painful for them, that’s the point. Standing up for principles and values is never easy, nor should it be. I’m sure it hasn’t been cheap or easy for Magpul to relocate, for instance.

          And states like Texas are practically throwing money at firearms related businesses to relocate there so it’s not as if there aren’t options.

          But instead, like most of our country, they seem to be fat, happy and lazy and so they’ll just continue to dutifully send tax revenue to a state that abhors them and their customers will continue to make excuses and keep buying their products…

          • Patriot Gunner

            If you mean that the “gun culture” recognizes that companies are free to chose where to produce their products in a free market economy (what remains) then yes that has “pervaded the gun culture.” On the flip side, we are free to choose where we spend our hard earned money and l wholeheartedly agree with you that we should vote with our wallets.

            I was in private equity for 6 years and I can tell you that the only businesses who pay state taxes are the ones who can’t afford lawyers to take advantage of the loop hole ridden tax code. I can
            bet you that SureFire pays little to no tax to the state of cali and does so 100% LEGALLY. However, I do agree that the state of CA cringes at the idea that the common citizenry can own suppressors. Keep in mind that SureFire started in CA back in ’71, things were a lot different back then.

            Also, comparing Magpul to SureFire is not an apples to apples comparison. I think Magpul makes some GREAT products,
            but their bread and butter is in polymer mold injection with very little military contract business. On the other hand, SureFire’s business is primarily in military contracts and makes products which are more complicated, labor and machine intensive from a manufacturing standpoint and set to a more stringent military standard.

            The thing that we should BOTH be upset about is not that SureFire remains in CA, but the fact that they are not a outspoken staunch supporter of the 2nd Amendment. SureFire is a private business under obligation by NO ONE to move to a gun friendly location and demanding such a thing makes us no different than the anti-liberty, freedom haters who demand that guns should be banned.

          • echelon

            I never “demanded” such a thing. I was merely stating that I think it’s regrettable that companies put up with what they do…it just strikes me as a bit hypocritical to stay in these places – but you and I are in absolute agreement that they can and should if they would like to. And we are also in agreement that the consumers can and should buy or not buy a product from a company based on their own personal subjective measures.

            So I was just stating that it’s ridiculous to likewise further the notion that they are somehow in need of special support or should be favored above other companies because they are “trapped behind enemy lines” or other such kinds of nonsense. But hey, if that’s what people believe, then so be it.

            If people believe in their product and don’t care about their location/stance, then they are and should be free to vote with their wallets as they see fit. The same could be said of a company in China, Russia or anywhere else.

            And you and I are free to voice our concerns and opinions openly in a collegial fashion. But you can’t tell me out one side of your mouth that I’m somehow not honoring a free market economy by exclaiming that I shouldn’t proffer the notion that customers should influence companies to move to more 2A friendly jurisdictions and then out the other side demand that both of us should be concerned that they are not staunch supporters of the 2A…it’s no different. They are not under any obligation to be supporters of any amendment, they can just produce products and make a profit. Right? Doesn’t it work both ways?

            Since I’m not privy to SureFire’s actual tax payment history, I’ll refrain from commenting on any speculation thereof.

  • iksnilol

    Uh, wouldn’t it be a good idea to include a db reading if your main selling point is how quiet it is?

    • BattleshipGrey

      For the prices SF wants for their products, it better be the best, but yes, they should not be above proving it.

      • BuzzKillington

        SF’s suppressors are great because of their mounting and low POI shift. AAC is typically a quieter can. Though, for .30cal that’s now tentative with this new claim. However, we all know that db reduction is a large variable that changes from location to ammo. I’ll sacrifice a db or two in reduction for longevity, solid mounting and minimal shift.

    • BuzzKillington

      A listing of decibel reduction is pointless. It’s only ever a range, because there’s no way to give a guaranteed reduction level for all environments with all ammo. It don’t ever base my suppressor buying decisions on the listed db reduction. User feedback, tone, and mount integrity is most important.

      • iksnilol

        Well excuse me for wanting to know cirka how quiet a suppressor is before buying it.

  • wetcorps

    Isn’t this claim pretty much mandatry when releasing a suppressor?

    • iksnilol

      I saw a suppressor (Sonic 45, probably not available in the US) that is marketed as the “allround suppressor” and “best value for money”. It’s pretty cheap and seems to work well while being very flexible (telescopic plus modular design helps).

      They didn’t mention anything about being quieter than the competition.

  • Theo Braunohler

    Good luck ever being able to buy one. As far as I can tell, they manufacture about 11 silencers per year. Almost everything they make is perpetually sold out, everywhere.

  • micmac80

    WTF 1+K $ suppressor

    • Don

      Where have you been, there are tons of $1k + cans out there. As more states start to allow them and more people start to buy them the prices will go down. And like everything in life, you get what you pay for…

      • iksnilol

        Doesn’t have to be. I can find a better suppressor for less money… then again I am in a country which has no control on suppressors

        EDIT: It’s naive to think that Surefire isn’t taking advantage of their name and reputation to jack up prices.

        • micmac80

          True that

          • iksnilol

            “Problem” is we don’t do the whole QD thing. We just keep them on our guns and remove them for cleaning/storage. And usually we have one suppressor per gun.

            That’s where American suppressors have an advantage IMO. But for me American supppressors are way to long so I don’t find thema that attractive.

      • micmac80

        Finland that is arguably the home of the modern suppresor things are still built at max half that cost and you would be hard pressed to get much of an upgrade with a surefire socom ,over a comparable Ase ultra.

        • BuzzKillington

          There are cheap suppressors available in the US for less than half of what SF’s cost. But when we’re required to pay a $200 tax, register, and are essentially stuck with the suppressor for life because nobody is buying used suppressors these days, it’s foolish to buy a cheap bargain suppressor. I can’t even recall how many forum threads I’ve read from cheap guys who bought suppressors from no-name companies because they were only a few hundred dollars, and wound up with baffle strikes, exploding suppressors, POI shifts worse than shooting spitballs, and nonexistent customer service from the company that sold the junk. SF is definitely an overpriced company, but nobody has ever argued whether they make quality products. It’s important for us in the US to buy quality NFA items because they will be sticking with us for a long time.

          • micmac80

            ASE Ultra are very high quality and at less than half price ,reflex are a bit less sophisticated but 1/3 the price no low quality stuff many are full auto rated and company has some 3+ decades of suppresor experience, you are plainly being ripped off if you pay 1k$ for Suppresor but that is US of A land of dreams where you can sell anything with a bit of hype

          • G

            The Finnish suppressor manufacturer is called Ase Utra. (Utra is spelled without an L)

      • Dan

        I don’t think prices will go down, firearms industry has a habit of raising prices

  • Random FFL

    Hello beautiful. Prepare to be mine.

  • JoeSchmoe

    Ok sooooo….claims to be the quietest on the market, yet fails to present a single detail,statistic or even subjective anecdote regarding its performance or the conditions under which it was tested. Silencer companies really grind my gears, folks. Its like buying a car at some shady third hand dealership because a commercial told you its the DEAL OF THE CENTURY, not actionable in court for false advertising because it cant be substantiated due to the subjectivity of the claim, yet absoulte hogwash by any practical measure. F’ing snake oil sales tactics, and they’re almost all guilty of it.

  • desert

    I notice there is no video to prove how quiet they are!!

  • Leonard Bayard

    Good grief, was this article written by a muppet? Purely copy and paste, couldn’t even take the time to correctly put in the surefire link. Click on Surefire in the article and instead of going to the product page, you’re sent to a website selling cheap holders for surefire flashlights.

    Seriously guys, at least spend 30 minutes waking up and grab a cup of coffee before getting on the keyboard, embarrassing….

  • Sounds promising, but the QD collar w/ locking tab makes it a non-starter for me. I’d want to run it under the handguard (e.g. 8.5″ bbl .300 BLK with 15″ handguard) for that “integrally suppressed” look and feel, and it wouldn’t be possible with this can.

  • BuzzKillington

    Really like what SF is doing with their new SOCOM cans, but it totally bums me out that the only flash hider mounting options are the prong-typed. Couldn’t stand the *ping* of the Smith Vortex FH and ditched it after one range trip. Wish SF retained their 212-A flash hider as a mount for the new SOCOM line.
