grapotThe 10.75″ Knight's Armament Company Free Float RAS 5 handguard was developed for use on the Secret Service (USSS) SR-16 platforms and is specifically optimized for modern KAC upper receivers featuring a notched receiver configuration with an 11.5″ barrel. The enhanced barrel nut interface, combined with robust construction, keeps deflection to a minimum. The host receiver must have a corresponding notch on the top rail. Works with CQB 2.1 and KS3 upper receivers. New, never mounted. No trades. Dog is not for sale, but is easily bribed with double doubles or caniac combos.
