The X01 (Exo One) Exoskeleton is a drop-in PDW upgrade for the Sig Sauer® P320® and P250® series of firearms that provides enhanced capabilities such as the ability to attach an SB Tactical™ arm brace or buttstock, such as those compatible with the SIG® MCX series.

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 M-Lok® slots, two of which come standard with specially designed handstops that integrate with the grip module’s contours.
