View Full Version : XTR-12 SBS

February 23, 2017, 00:17
Hello fellers,

I have what may be a dumb ass question, but here it goes. I have a UTAS XTR-12 and I want to Form 1 it into a SBS. The shotgun has a DPMS style lower receiver and accepts DPMS AR-10 uppers in any caliber (you just have to change out the buffer and buffer spring).

My question is......If I Form 1 it as a 12 GA SBS, could I swap between lets say a !2.5" 308 upper on it and still be legal? The lower receiver is marked "12 Gauge" as the caliber.

Here is a link to a video of it so everyone has an idea of what I'm talking about:
