X01 with BRACE – FCU for P320


THIS COMES WITH THE BRACE!!!!The X01 (Exo One) Exoskeleton is a drop-in PDW upgrade for the Sig Sauer P320 series of firearms that provides enhanced capabilities such as the ability to attach an SB Tactical arm brace or buttstock compatible with the SIG® MCX series (optional add-on). The X01 enhances the original firearm’s manual of arms with its integrated charging handle, which provides an “HK-style” downward release when locked to the rear. The fore-end of the weapon features three M-Lok slots that integrate with the grip module’s contours.
