While set up at a gun show this weekend, I had my first urge to build an AR pistol. I've always seen them as kind of goofy and didn't really know if they had a point. I imagined them to be awkward to fire and not being very accurate.
All that changed when I caught my first glimpse of the Sig arm brace. I know these have been out for a while, but I guess I didn't see the "secondary" purpose of the brace. Me being naive that I am, I only considered the original purpose and thought that it was even more goofy and pointless. But after seeing one in purpose, the "secondary" purpose hit me like a ton of bricks. Now I think I just HAVE to have one. It's an SBR without the negatives of an SBR. No dedicated lower that has be engraved and has limited resale options, no special fee to pay to the ATF, and no 13 month wait for approval.
I'm really, seriously consider this for my next build. Slap a Sig brace on and it can be sold as a pistol without any problems of trying to resell a SBR. I'm still leaning towards a 5.45x39 for my next build. Is there any problems associated with doing a 5.45x39 in a pistol? I'm think 8.5" to 10" barrel. Looking to heari thoughts on this idea.
