The GRS Bag Rider is made to fit the rear Picatinny Rail of the Ragnarok, Bifrost, Warg, and Bolthorn GRS stocks. The GRS Bag rider gives you a much better "less friction" surface towards using your GRS Rear Bag, and it helps to give the rifle a more even recoil transfer into your shoulder. This bag rider is made of anodized aluminum and is very durable and easy to install.
