The A645 Side Mount is designed for Flat Top MSRs and other tactical style firearms. It provides a 45 degree accessory platform that attaches to a Picatinny style rail. The A645 Mount can also be mounted to the rail on the hand guard to allow your back-up sight to co-witness with the sight on your R.A.M.P. Mount.
