The FN SCAR Non-Reciprocating Charging Handle Conversion (brand part no. 20-100505) is an upgrade assembly for the FN SCAR 17S and 20S that swaps the factory reciprocating charging handle system for a non-reciprocating design. The kit includes a new NRCH bolt carrier, a charging handle sled, and two ambidextrous, reversible charging handles that lock forward when the bolt closes and stay static during firing, so the handle no longer moves back and forth with every shot. That static handle gives shooters more consistent forward-assist-style manipulation and lets them run the rifle from either side without switching which hand operates the charging handle. FN designed the NRCH system to improve the handling characteristics of a platform that, in military configuration, has already served elite units for more than a decade.
