The GRS Rear Bag is made to fit the rear Picatinny Rail on our Bifrost, Warg, Ragnarok and Bolthorn rifle stock models. Made in anodized aluminium it is very durable and easy to install. Take the locking screw out of the GRS bag rider. Slide it on to the rear Picatinny rail. Line up the screw hole with the slot in the Picatinny rail. Insert the screw, tighten the screw, it does not need much torque to fasten. 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 shows on the target! Made from 60 Mfg: Grs Riflestocks
