The other day, everyone’s favorite deadbeat Dad (the ATF 😜) decided to change their mind and finally give all of us AR Pistol owners permission to shoulder our SB15 Sig Brace again …. as if any of use were asking for permission in the first place. This came after representatives for SB Tactical, the designers of the SB15 Brace, requested sent a letter to the BATFE asking for them to reconsider. You can read all about that specific change here. This change brought up a lot of confusion as to whether or not it also applied to the many other “Pistol Braces” on the market from other companies such as my personal favorite, the Shockwave Technologies Blade. I’m happy to say that the ATF says it does apply to other braces too. Read below!
Our friends at Shockwave contacted the ATF themselves to get clarification on whether or not the recent reversal also applied to their Blade Pistol Stabilizer and here is what they found out…
I just got off the phone with a very nice gentleman at ATF Tech Branch—who was fielding these calls today. (He was, understandably, very well versed on the subject—and very nice about it even though he’s been on the phone all day, repeating himself ad nauseam.) I identified myself and asked him specifically if the letter that’s making the rounds is limited to one company’s products–or if it applies to all pistol stabilizing braces. He said: “The letter covers all pistol stabilizing braces, including the Shockwave Blade.” So that settles that.
He then gave me a bit of further guidance for our customers:
- By “permanent affixing,” ATF considers that to be adding permanent Loctite to the large set screw that secures the Blade into the dimples in the KAK tube. As long as you don’t red Loctite the set screw in place, ATF considers it to be “temporarily placed” and “perfectly okay to shoulder.” (He didn’t beat around the bush on this topic.)
- “Length of pull”—for lack of a better word regarding pistol braces—begins to enter a “gray area” above 13.5″. Above 13.5″ begins “to enter shoulder stock area.” (His words. I believe this has to do with the “comfortableness” aspect.) On an AR-15, the “length of pull” for the Blade is approximately 13.13″, so no issues there. But if you use the Blade on a firearm that requires a large adapter of some sort, please make sure that you only use the dimples up to the point that you remain below the 13.5″ length. Stay below 13.5″ and according to ATF, it’s okay to shoulder a Shockwave Blade.
This information was posted on the Shockwave Technologies website. You can read it for yourself HERE. While this is just relaying information from one source based on a phone call they had with the ATF, I do know the source and trust that this information is correct. From what I’ve heard, the ATF will be issuing a letter clarifying that this covers all Pistol Braces and not just the SB-15.
If all this AR Pistol talk has got you itching to build another one, check out the KAK Industry SHOCKWAVE kits. They are pretty much exclusively what I use when building an AR Pistol and can’t speak highly enough of them.
