AR pistol aficionados will dig this new non-buttstock grip enhancement. The SIGTac SB15 Stabilizing Brace slips over an AR buffer tube. It combats muzzle rise by bracing the buffer tube against the top of the shooter's forearm with a channel and strap arrangement.
At first glance, the SB15 looks a lot like a buttstock that would get you in trouble with the ATF. But, watching the video made a few things clear that keep it in the realm of the up-and-up. For one, there's no real butt pad surface and it's soft-ish. The flexible material doesn't look like it will do anything to control recoil if shouldered. It also doesn't really install, so much as slip on.
Given all of that, Sig states explicitly that it has ATF approval. Well, yeah. I'd still print out and carry Sig's ATF letter with this device. It looks enough like a buttstock at a glance to raise eyebrows on the range.
No word on price, yet. But Sig is releasing the SB15 at the NRA Annual Meeting this week.
