Fightlite Mcr060S Mcr Dual Feed Upper 1913 12.5

Overview

The Fightlite MCR060S is a groundbreaking, dual-feed belt-fed upper receiver assembly designed to interchange with standard AR/M4 type uppers, fitting any MIL-Spec lower receiver without permanent modification. Compatible with AR-15 and M16 models dating back to 1963, the system is chambered in 5.56x45mm NATO (.223 Remington) and utilizes a short-stroke gas piston operation for extreme reliability in adverse conditions. The upper features a 12.5-inch quick-change barrel system with a 1:7 right-hand twist and 1/2-28 TPI, a quick-change barrel handle, and a MIL-STD 1913 co-planar rail-interface handguard. The dual-feed system accepts standard box-type AR-15/M16 magazines as well as M27 linked ammunition. Constructed with a precision-machined 7075-T6 billet upper receiver, feed cover, charging handle, and billet steel feed tray, the assembly is finished with a combination of manganese phosphate and Type III Class 2 hardcoat anodizing in black. It includes a full-auto bolt carrier, an adjustable sight set, main action spring, bolt catch, carbine stock spacer, 100 M27 links, and an operator's manual. Made in the USA.
