KRISS Vector G3 Folding Stock

The KRISS Vector G3 Folding Stock is the factory buttstock for the Gen 3 Vector. It bolts to the 1913 Picatinny rear rail with two M5 screws, so it is a direct fit on any Vector that presents that rail without an adapter. The hinge is fully ambidextrous, letting you move the release button to the top or bottom and fold the stock to either side, which matters on a Vector because the tall sight line and rear-heavy balance reward folding to whichever side clears your optic and charging hand.

The stock runs three length-of-pull positions, so it adjusts for plate carriers and bare-shoulder shooting without tools. A 7075-aluminum folding hinge with a steel locking point carries the load while the polymer body keeps weight down on a platform that already carries its mass high and rearward.

This is the right stock for Gen 3, 1913-rail Vectors. Gen 2.1 (2017) Vectors use an integrated AR buffer-tube interface and take AR-pattern stocks directly, while Gen 1 and pre-2017 Gen 2 Vectors use a proprietary hinge mount and need an adapter such as the HB Industries folding stock adapter to run an AR stock.
