I’ve written in the past about devices and/or gimmicks such as the Halix NSN chin brace that will allow you to use an AR-15 pistol as a PDW or personal defense weapon. The general consensus at the time was that it had marginal utility and that the ATF would probably decide it was a stock.
Now comes word that Sig Sauer’s SIGTac line is coming out with the SB-15 stabilizing brace. As you can see in the video below, it is a method of strapping the recoil tube to your forearm. According to SIGTac, it is ATF approved. They plan on rolling this out at the NRA Annual Meeting so I’ll be interested in seeing the approval letter.
It does appear effective in stabilizing the AR pistol. No word yet on the price.
UPDATE: The ATF approval letter can be found here. Also, according to a comment on this post, the MSRP for the SB-15 will be $139.
