The KRISS USA Vector CRB Gen 3 in 45 ACP is a semi-automatic pistol caliber carbine built for shooters who want accurate, controllable fire in recreational and competition settings. With a 16-inch barrel, the Vector CRB stays compliant in most states while delivering the handling and ergonomics that make this platform a favorite in PCC (pistol caliber carbine) divisions. The Gen 3 redesign brings a more versatile platform: updated upper and lower housings, refined controls, and modern modularity that reward both casual shooters and serious competitors.
Fed by full-size Glock magazines, the Vector CRB eliminates the need for proprietary ammo storage and lets you use gear you likely already own. The refreshed barrel shroud includes M-LOK slots for mounting lights, lasers, or rail sections without guesswork. You get an ambidextrous adjustable folding stock, ambi mag release, and ambi safety lever—features that make the platform equally comfortable for right and left-handed shooters. The skeletonized trigger with minimal pre-travel and the closed-bolt delayed blowback action combine to deliver clean, predictable shots downrange.
Built from 4140 chrome-moly steel with black nitride finish, the barrel is threaded .578x28 for suppressor compatibility if you want to take the next step. A full-length Picatinny rail on top gives you unlimited optic choices, and the short charging handle with brass check keeps your support hand in the fight. At 7.7 pounds, the Vector CRB is lightweight enough for all-day range sessions or competition stages, yet sturdy enough to handle hard use. The package ships with a 30-round magazine, cleaning kit, cable lock, and manual—everything you need to get running.
