B&T 320 USW Chassis Upgrade for SIG P320
This video showcases the B&T 320 USW chassis, a conversion kit that transforms a SIG P320 pistol into a Short Barreled Rifle (SBR). The process involves dropping the P320's fire control unit (FCU) into the B&T chassis and attaching the SIG slide and barrel. The key feature is a compact folding stock that allows the firearm to be used like a pistol with the stock folded or deployed like a carbine. The video emphasizes compliance with NFA regulations.
