Fightlite Industries 15076 MCR Main Action Spring 223 Rem/5.56 NATO

The Fightlite Industries 15076 Main Action Spring is a factory replacement main action spring designed for the Mission Configurable Rifle (MCR) platform chambered in 223 Rem / 5.56 NATO. It drives the main action of MCR belt-fed and magazine-fed upper configurations, keeping the action cycling reliably with both feed systems.

Constructed from steel and built to factory specifications, the 15076 matches the original equipment spring, making it an ideal drop-in replacement for worn or lost springs. Whether you maintain an MCR for duty, training, or range use, this genuine Fightlite part helps keep the action running smoothly round after round.

Designed specifically for the MCR rifle family in 223 Rem / 5.56 NATO, the 15076 is a smart spare to keep on hand for field maintenance, gunsmithing, or emergency replacement.
