More Brace Options From SB Tactical

SB Tactical has changed the world of pistols. Infamously known as the “Sig Brace”, the SB15 opened up many options for pistols. Regardless of the ATF letters, it is a product that has significantly altered the firearm industry. I only knew of their two versions offered by Sig Sauer. The SB15 and the SBX.

Well they have four other models. Two of them are for HK style pistols. HK93 MP5 style weapons.

SB-MP5K-Side-On-Weapon-600x338 SB-MP5-Side-On-Weapon

SB tactical also has an AK variant sold exclusively through Century Arms.




The PSG brace is the most interesting.  It looks just like a KRISS Vector Stock.



Here is a mockup I photoshopped to show how it would look.



Here is a KRISS Vector SMG for comparison.



If you want to know more or buy one of these new braces, go to SB Tactical’s website.

    Did they jack the price up on the HK models because HK owners are used to paying more, or did they just think the shark fin look was worth the extra $100?

    • FWIW

      I’d imagine it’s a little from column A, and a little form column B.

      • Nate

        Danger Zone!

    • Nicholas Chen

      Actually if you look at the website, the extra $100 is for the buffer tube and adapter to mount it to your MP5 pistol.

      HK Parts makes the adapter. They charge $300 for the same setup.

  • Wingbert

    Yay.. more sig useless brace!

    • Nicholas Chen

      How is it useless? It works as designed. And they have sold something like 300k units. If it was useless they woudn’t be selling any. And yet they have contracts with IWI, Sig and other comanies.

      • Kivaari

        That is a good amount of product they are moving. I am thinking of buying one of the SIG pistols and doing a Form 1 SBR paperwork. The pistol has the features I want on the SBR. It seems like one of the best ways to get a high quality product.

    • Ethan

      Extremely useless.
      So useless in fact, they are generating HUGE amounts of sales and a dozen major manufacturers have created product lines specifically for use with it.

      When was the last time you created something that “useless”?

  • Phil Hsueh

    So, has anyone wrote to the ATF to see if it’s legal to shoulder these arm braces yet?

    • ARluv

      Hope you’re joking…

      • Phil Hsueh

        You mean you couldn’t tell that I was serious? J/k. Yeah, I was joking but I wouldn’t be surprised if the ATF still ends up getting letters from people thinking that maybe their previous ruling only applied to Sig braces and this would be different since it’s not a Sig.

  • USMC03Vet

    So much room for activities. Don’t touch the shoulder, Bro!

  • Kelly Jackson

    We’re not even pretending that this isn’t a stock anymore right?

    • Cymond

      You’ve got that backwards. Using it as a stock makes a pistol into a SBR … somehow. Don’t ask me to justify ATF’s logic.

      If we’re “pretending” anything, it’s that these are never shouldered by anyone ever.

      Personally, I’m not messing with one on a defensive gun because I know I would probably shoulder it in the heat of the moment. On a fun-gun? I don’t intend to shoot one-handed, and I’m not willing to risk misusing one.

      • David

        With any luck the guy you shoot is now dead, so the only story that matters with be yours anyway, and you never shouldered it….right? Riiiiiiiigggghhhttt

      • Bill

        I still think it’s legal to shoulder it, but illegal to install it with the intent to shoulder it.

  • Cymond

    The website explains the PSG pretty well.
    “The SB® PSG Stabilizing Brace™ was developed for the Patriot Ordnance Factory’s (POF-USA) Patriot Sub Gun (PSG). This brace also fits the KRISS Vector pistol with an additional KRISS Vector M4 Adapter available through other retailers.”
    I think that’s interesting since the POF PSG doesn’t use a buffer tube but this brace appears to include one.

    (Insert middle finger to atf here)

  • MadMonkey

    I don’t shoot shirtless so none of these braces have ever touched my shoulder.

  • john huscio

    I prefer the shockwave blade
