Raider X P320


NOT A FIREARM! The Raider X is a micro PDW, intended as an option between a handgun and a rifle. With the speed, maneuverability and concealability of a handgun combined with the capacity and stability of a carbine, it offers greater capability when a rifle is too large to have with you.

  • COMPATIBILITY LIST: Sig M17/18, Sig P320™ Family of pistols – all of them will function, but check below for part incompatibility. WARNING! To use the P320™ carry, compact, and subcompact, you must use a comp, threaded barrel, or suppressor – serious injury could occur due to the location of the muzzle.
  • NOT COMPATIBLE: Will not work with suppressor height iron sights, nor will it work with 15 rd magazines. Will not work with M17/18 manual safety, but the manual safety can easily be removed from the FCU and replaced with an inexpensive OEM SIG pin. We do not accept returns of Raiders that have been modified. Safety mechanism does NOT work with all aftermarket triggers (Agency Arms) or forward set trigger kits! The Raider safety will NOT work with most adjustable triggers.
