Introducing the Kriss Vector Gen 3 Fixed Stock. The Kriss G3 Fixed Stock is a durable, polymer buttstock designed for a customizable and secure fit. It features three fixed positions that can be easily adjusted by removing a screw and latch, sliding the stock forward or backward, and reinstalling the screw and latch into one of the three preset positions. The stock slides smoothly along an aluminum guide rod, which has three holes drilled to match the same fixed positions as the standard folding stock. The clamp/mount is made of aluminum and attaches securely to your firearm using two M5 screws. Features3 Fixed PositionAluminum Guide RodDurable Aluminum Clamp
