The CMMG Enhanced Field Repair Kit (brand part number 55AFF62) packs the small parts most likely to break or walk off on an AR-15 into one Mil-Spec kit. CMMG includes three trigger springs, two trigger pins, a firing pin, firing pin retaining pin, extractor springs, an extractor, and two detent springs, covering the fire-control and bolt parts that fail first after heavy use. Every part is built to Mil-Spec tolerances, so it drops straight into a standard AR-15 without fitting. It’s a smart addition to a range bag or armorer’s kit for anyone who doesn’t want a broken spring to end a shooting day.
