The KRISS Vector SBR Gen 3 10mm in Two-Tone is a short-barreled rifle built around a 5.5-inch barrel, an adjustable folding stock and a Two-Tone finish (KRISS part no. KV10-3S2T00). At its core is the Super V Recoil Mitigation System, a closed-bolt, delayed blowback design whose low-mass slider drives blowback energy downward to counter muzzle rise. For Gen 3, KRISS updated the upper to take aftermarket pistol grips and reshaped the lower housing for better hand support. With full-size Glock magazine compatibility and a 33-round magazine included, it suits home defense, close-quarters training and fast range work.

Frequently Asked Questions

What is the Two-Tone finish? Two-Tone is one of the factory colors KRISS offers on the Vector SBR Gen 3, a two-color scheme applied at the factory rather than an aftermarket paint job.
