The FN SCAR Heavy NRCH Conversion Kit is a factory upgrade designed to convert compatible FN SCAR 17S and SCAR 20S rifles to the advanced Non-Reciprocating Charging Handle (NRCH) system. This drop-in assembly enhances the rifle’s modularity and shooter ergonomics with dual ambidextrous charging handles that remain static during fire and lock forward on bolt-close.

The NRCH system gives SCAR owners a more adaptable platform that better supports modern optic setups, alternate grip styles, and varied shooting positions. By eliminating the reciprocating charging handle movement during firing, the rifle becomes more comfortable and intuitive to run in a wider range of configurations.

This factory FN kit includes a new NRCH bolt carrier, charging handle sled, and two ambidextrous charging handles. It is an excellent upgrade for shooters who want the latest FN SCAR operating configuration while maintaining OEM quality and compatibility.

Compatibility Note: This Heavy kit is designed for the FN SCAR 17S and SCAR 20S. FN notes that upgrading a SCAR 17S requires the assistance of a qualified gunsmith to remove the front plate without damaging the rifle.
