KRISS Vector SBR Gen 3 9mm 5.5" Barrel 40rd Glock Mag Compatible Black Short Barrel Rifle

The KRISS Vector Gen 3 SBR delivers the most compact rifle-format performance in the Vector series, combining a 5.5-inch barrel with adjustable stock for fast handling and smooth transitions across multiple targets. The revolutionary Super V Recoil Mitigation System redirects recoil forces downward rather than backward, dramatically reducing muzzle rise and enabling rapid follow-up shots with unprecedented control. Combined with the world's lowest bore axis—positioned in line with the shooter's second knuckle—the Vector SBR provides mechanical advantage over recoil forces that conventional firearms cannot match.

The updated Gen 3 upper supports aftermarket pistol grips while the refreshed lower housing enhances ergonomics and hand support for improved shooting comfort. Compatible with full-size Glock magazines, the Gen 3 SBR ensures reliable feeding and flexibility with high-capacity options. Ships with one 40-round magazine, cleaning kit, cable lock, user manual, and warranty card.

Patented Super V Recoil Mitigation System

The KRISS Vector's revolutionary Super V System is a delayed blowback operating system featuring a small bolt carrier group connected to a low-mass slider guided by channels in the frame that run perpendicular to the barrel. As the bolt cycles, the system redirects recoil energy downward rather than straight back into the shooter's shoulder. This downward-directed energy becomes a counterweight to the barrel's natural tendency to rise when fired, dramatically reducing muzzle climb and enabling the shooter to stay on target through rapid strings of fire.

World's Lowest Bore Axis

The Vector features the lowest bore axis of any firearm in the world. The barrel is situated below the fire control group, positioned in line with the second knuckle of the dominant hand rather than high above it as with conventional designs. This placement gives the operator mechanical advantage over recoil forces, as the recoil impulse pushes straight back through the hand rather than creating a lever arm that rotates the muzzle upward. The result is flat shooting characteristics that keep sights on target even during rapid fire.

Compact SBR Configuration

The 5.5-inch barrel provides maximum compactness for close-quarters maneuvering while the adjustable stock enables proper length of pull for different shooters and shooting positions. This combination delivers rifle stability and control in a package barely larger than a handgun, making the Vector SBR ideal for vehicle deployment, home defense, and confined-space applications.

Gen 3 Improvements

The Gen 3 upper supports aftermarket pistol grips, providing customization options to match shooter preferences and hand size. The refreshed lower housing enhances ergonomics with improved hand support positioning and refined grip angles. These updates improve shooting comfort during extended sessions while maintaining the Vector's distinctive appearance and handling characteristics.

Glock Magazine Compatibility

The Vector SBR accepts full-size Glock 9mm magazines, ensuring reliable feeding with proven magazine designs available worldwide. This compatibility provides flexibility with capacity options and eliminates proprietary magazine concerns. Ships with one 40-round magazine for extended shooting sessions without reloads.

Fast Handling and Target Transitions

The compact dimensions, low bore axis, and effective recoil mitigation combine to deliver exceptional handling characteristics. The Vector SBR transitions between targets with minimal effort, as reduced muzzle rise eliminates the need for aggressive recoil compensation. This enables faster engagement of multiple targets and quicker follow-up shots compared to conventional pistol-caliber carbines.

Ambidextrous Controls

The fire control layout accommodates both right and left-handed shooters with accessible controls that don't require awkward hand positions or manipulation. The ergonomic design ensures all shooters can operate the Vector SBR efficiently regardless of dominant hand.

NFA Compliance Notice

This firearm is a Short Barrel Rifle (SBR) regulated under the National Firearms Act. Purchase requires ATF Form 4 approval, $200 tax stamp, and compliance with all federal, state, and local NFA regulations. Transfer must occur through an NFA-qualified FFL/SOT dealer.

The KRISS Vector SBR Gen 3 redefines what's possible in a compact 9mm platform—revolutionary recoil control meets rifle format precision.
