X-Ring give their take on the B&T BWC9, a folding gun chassis design, at the range. The BWC9 is a folding chassis for SIG P320 pistols that unfolds from a compact, briefcase-like form into a rifle with a flick of the wrist.  It utilizes your existing P320 FCU and slide (subcompact to X-Five lengths) and includes an Aimpoint sight, but not suppressor-height sights.
