The KNS Precision Discarder Adjustable Gas System for FN SCAR (brand part no. DISCARDER-FN Scar) solves the over-gassed feel that’s common on the FN SCAR platform, giving you an adjustable gas system that tunes down excess gas instead of just living with it. An over-gassed SCAR runs harder than it needs to, which means more felt recoil, faster wear on internal parts, and more violent ejection than necessary for reliable cycling. KNS Precision’s Discarder lets you dial the system back to what the rifle actually needs with 14 toolless adjustment positions. It covers the SCAR platform broadly, with the exception of the SCAR 15P and Gen 3 SCAR.
