1. Just a warning to not swap that brace out with a stock, and to make sure the lower was transferred to you as a pistol or “firearm”, not as a rifle.

2. Get a lower called a firearm in case you ever want to change the barrel. If by an nfa item they mean it needs to go to an FFL then find another dealer

4. It’s a CYA that they warn you not to buy this and make something illegal out of it.

5. While on this subject… can I take a “pistol” AR lower and change the buffer tube for a rifle’s and add a stock on it, to use with an 16″ barrel upper or is that another murky ATF don’t-do-that?
   Had plans to build a 9mm AR pistol with a SBR upper, but changed my mind years back and never bought the 9mm SBR upper to finish the pistol. Now I’d like to reclaim that lower to use for a regular AR rifle.

   Thoughts?

6. NO!!!! Dont make an AR pistol lower a rifle!!! If its stamp PISTOL it remains a pistol. And dont put regular stock on it that makes it an S R. Yes its stupid but thats the rules.

7. You can put a 16″+barrel and a stock on a pistol and then remove them to put your pistol length barrel and arm brace back on it.

   This was decided in 1992 by SCOUTS in “United States v. Thompson-Center Arms Company”.

   There’s even an ATF ruling 2011-4 on this.

8. That’s exactly what it means. Don’t play around and put this 7.5″ upper on that 16″ ar you bought last year.

   I was at a gun show one time and watched a customer walk up to a booth and take the upper off a pistol, put it on a rifle lower, and then ask the guy behind the table how much it would be for the package.

   To his credit, he said “about 20 years” and then took it back apart. He calmly explained why he couldn’t do that and the customer left in a huff.

   We tend to forget that the NFA just isn’t going to be something that most people are aware of. A little bit ago I was at someone’s house and they brought out an AR pistol to show off to the guys. It had a vert grip on it. I got some very nasty looks when I told them that wabads

9. Thanks for the info, gents.

   I don’t recall seeing a “pistol” stamp on the lower. It’s a PSA lower like this one:

   Have to dig out the lower from the stash to confirm but it appears that it is a regular AR lower with just the buffer tube being “pistol” specific.
   Worse case scenario, I’ll just sell the darn think and get a nakid PSA lower and build it from scratch. Got plenty of spare parts around.

10. A 7″ bbl 5.56 will be rather… um, concussive. Additionally, might the gentleman perhaps prefer a more ballistically advantageous 10.5″ or 11″ barrel?

    1. I think I am gonna go 9mm carbine eventually.

11. As to a short barrel(10.5) AR being “concussive”…uum yup it is, but its LARGE fun. You can hear my m16 8 miles away…sure makes the hippies round here jumpy. Heh heh. Guys, please dont mess around with AR barrel length, it is a completly different animal than a Thompson Contender.

    1. More specifically, 5.56’s primary ‘tool’ is velocity. 10.5/11″ is loud too but it’s pretty much the minimum to maintain some type of (short range) performance. 10.5/11″ is also the minimum length to avoid damaging many suppressors (RTFM). 7.5″ is roughly a 1/3 of the original fielded barrel length and IMHO designates the firearm as ‘excessively loud range toy’. For extra loudness, use a muzzle brake; it’ll remind you why suppressed shooting is polite shooting.
