Finished in black, the KRISS Vector SBR Gen 2 10mm in Black is a compact 10mm short-barreled rifle from the Gen 2 Vector line with a 5.5-inch threaded barrel (KRISS part no. KV10-SBL20). 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. Like every Vector, it feeds from full-size Glock magazines, which lets it share ammunition and magazines with a Glock sidearm. KRISS ships it with one 33-round magazine, a 2-stage quick-reset trigger and low-profile flip sights, so it is ready for the range, home defense or a suppressor.

Key Specifications

• The chambering is 10mm, a hard-hitting magnum pistol round.
• Barrel length is 5.5 inches, and the barrel is threaded for a muzzle device or suppressor.
• The twist rate is 1:10 right-hand, a rate KRISS uses across the Vector SBR calibers.
• Overall length is 24.00 inches collapsed and 27.25 inches extended, very short for a shoulder-fired rifle.
• Weight is 7.0 pounds, enough mass to help settle a short barrel.
• It ships with one 33-round magazine and accepts full-size Glock magazines.
• The finish is black, the standard Vector color.

Frequently Asked Questions

What does the Super V system do? It is a delayed blowback design that sends blowback energy downward, which reduces felt recoil and muzzle climb.

Do I need ATF approval to buy this? No. As of October 9, 2026, ATF no longer requires Form 4 approval, registration or a tax stamp for short-barreled rifles.
