SB Tactical Continues (Gun) World Domination Plan with SPBDW Brace

SB Tactical, known for giving the ATF a headache and us poor pistol owners a practical “brace”, is at it yet again with their plan to dominate the Modern Sporting Pistol market. This time, SB Tactical has teamed up with Maxim Defense to release an adjustable arm brace modeled on the Maxim Defense CQB Stock. 

The Maxim Defense CQB system is a two-rail, three-position MP5 style “stock” for the AR-15. The system features a very quick extension method, where the shooter can overhand cup the stock, depress the button, and yank to the rear for full extension in seconds. (On a personal note, it really is that easy – I have one). Fine adjustment to the two shorter settings can be accomplished by finer adjustment, but it is still quite simple.

The CQB does require a proprietary buffer system, which Maxim Defense covers in style with a custom JP Enterprises Silent Capture System featuring two buffer weights instead of the usual three, which covers the vast majority of shooters out there.

The SPBDW is shipped ready-to-install on any pistol lower receiver. Pricing is set at $299 retail for the black version (in stock) and $319 for the FDE (which is out of stock as of this writing). 

Like all SB Tactical’s arm braces, the SBPDW is fully ATF compliant when used in accordance with the law.

    Thanks for the heads-up! I was just wondering when it was going to be released.

  • Rick O’Shay

    That adjustment button looks like it’d dig into the wrist pretty good. Did it have to be so big? Or does it just look that way?

  • BetweenTheNipplesisOK

    Don’t shoulder it…but chesting it is ok. (between the nipples)

  • int19h

    Is that brace hard rubber, like on other SB products, or rigid polymer, like Tailhook?

  • Cymond

    $300 is pretty good, considering their PDW stock starts at $400. Are we sure that includes the buffer?

    • Sam

      not the same. Maxim and SBT collaborated on the design, but SBT’s product uses standard-length buffer tube and standard buffers and springs (and different QD mount location). Maxim’s is basically a brace version of their stock, including proprietary tube/buffers.

      • Cymond

        Thanks. I see that now, looking at the SBT website, but it was really unclear from the article. I’m not sure why the article talks about Maxim’s proprietary buffers.

    Nathan S. I have the SBPDW brace as well. It does not require a proprietary buffer system. I am using it in my 9mm AR build.

    Once(if) these things drop into the low $200 range, I’ll be on it like white on rice.
