The Kinetic Research Group folding stock assembly is a robust and ergonomic upgrade for KRG X-Ray, Bravo, 180-Xray and CZ455 chassis systems, as well as Sako TRG-22 and TRG-42 rifles, replacing the back half of the current TRG-22 and TRG-42 stock. It is fully tool-less adjustable for length-of-pull, cheek height, recoil pad vertical position and cant. The latch mechanism features a proven spring loaded tapered detent design to provide a tight lockup throughout the life of the stock and ambi QD sling points are included.
