The FR-1 Fire Control Mount (FCM) is fire control and laser range finders to be mounted directly to the FR-1 Optics Mounting System. It attaches to the FR-1 Mount with a three-point steel dowel system anchored in place by a single screw at a 45° angle. This gives the FCM excellent strength and rigidity as well as laser zero retention. This design also allows laser systems to remain attached to the rail during take down with a single screw for fast accessory change in the field without the need for extra tools. The FCM features a stowaway compartment for the Cant Detection Level. Constructed from 6061 T6 aluminum with Mil-Spec type III hard coat Teflon finish.
