Officially licensed by KRISS, the Vector GBB runs on green gas and fires in semi, two-round burst or full auto.
The receiver is fiber-reinforced polymer, and the whole gun weighs 5.1 lbs. MIL-STD 1913 rails on the top and bottom give you room for an optic, a light or a grip. It comes with low-profile flip sights and the licensed KRISS folding stock.
The Vector GBB runs on a bolt assembly KRYTAC designed specifically for gas operation. It’s lightweight, which keeps the rate of fire up and gets more shots out of every fill. The trigger uses the Vector’s pivoting design, and the safety and fire selector are both ambidextrous.
The top-down hop-up adjusts in 23 clicks with the included 2.5mm hex key. You can hear and feel each one. Swapping the inner barrel for a different length doesn’t take a full teardown.
Each green gas magazine holds 60 BBs and is made from lightweight aluminum alloy.
In colder weather, use a gas rated for higher pressure or cold temperatures.
