Never Shot, the customer purchased it from our store and brought it back in the original case. Comes with 1 13-round Glock Magazine. The KRISS Vector CRB is the most widely accessible model, with a rifle-length barrel. The Vector CRB is 47-state compliant. The Vector CRB is the ideal choice for recreational use and competition in pistol caliber carbine divisions. Like all KRISS Vector firearms, the CRB is fed with full-size Glock magazines, allowing for a wide range of large capacity options. At the heart of the Vector CRB is the Super V System, a nonlinear, multilink, blowback system designed to redirect recoil energy down. The Super V System, in conjunction with the low bore axis, reduces felt recoil and muzzle climb.
