FTLT MCR Dual-Feed Upper – 5.56 NATO, 12.5-inch

Description

The FTLT MCR (Mission Configurable Rifle) dual-feed upper receiver is a drop-on assembly designed to interchange with standard MIL‑Spec AR/M4 type lowers without permanent modification. Engineered for modularity, the patented system allows user configuration in seconds and offers rearward compatibility with AR15/M16 platforms produced as early as 1963. Standard features include short-stroke gas-piston operation, a 12.5-inch quick-change barrel, and a MIL‑STD 1913 co-planar handguard for mounting optics and accessories.
