KRISS Vector G3 SBR 9mm | 5.5 in | 40rd | FDE

The KRISS Vector G3 SBR is the shortest rifle variant in the Vector family, built around a 5.5 inch threaded barrel for compact handling and accessory mounting. It uses a closed-bolt, delayed blowback operating system and ships with a 40-round magazine and folding telescopic stock. The Gen 3 upper and lower housings accept aftermarket pistol grips and provide improved hand support. A low-profile reflex sight such as the Holosun 507C X2 pairs well for fast target acquisition without exceeding typical optic budgets under $1000.

Applications: pistol-caliber carbine (PCC) competition and close-quarters range training are two common uses for this platform.
