Too cumbersome to fire with one hand? I fired a Serbu super-shorty one handed. And I'm not a Schwarzenegger by any means.Who the hell knows for certain. That's the problem. It might not be if it's' over a certain weight and barrel length with an RDS type sight that could be used on a rifle and it's too cumbersome to fire it with one hand it might not be classified as a pistol even without a brace.
Well..... Suppose you have an upper with a 10" barrel. No law against that. And if you have a different upper, one for every rifle lower in your possession, one could presume that you're "good to go", esp. if you have paperwork in for a SBR. You can convincingly make the case that you are assembling a SBR, but waiting to do so for your stamp to be approved, as required. If you have a lower assembled and don't have an upper on it, though, "constructive possession" has reportedly been used as a charge.If I understand it correctly, the current issue is for a proposed change that happens a set time down the road. The MrGuns... video posted above outlines it.
Interesting question in case this goes bad for us though. If you separate your brace from your pistol, is everything good? How much separation?
And don't get me started on the "fuel filters" being sold online, presumably by ATF. As long as the buyer doesn't own a firearm, I suppose they're probably OK.
The person of whom I'm thinking, however, has an AR with a short barrel, which has to my knowledge, never had a stock on it. Never a brace, a stock, or anything else but the recoil assembly. I know *I* fired that Serbu at NFA Day, one handed, and really had no trouble with it at all. it would seem to me that the AR in question would be at least as easy to fire as that.
