The Aero Precision AR15/M4E1 Field Repair Kit (brand part no. APRH101625) packs the small parts most likely to rattle loose or break on an AR-15 or M4E1-pattern rifle into one range-bag-ready kit. It covers 2 AR15 takedown pin detents and springs, 2 roll pins for the forward assist, 2 bolt catch springs with a bolt catch buffer and roll pins, a trigger and hammer pin, a safety selector spring and detent, a buffer retainer with springs, trigger guard roll pins, pistol grip hardware, trigger and hammer springs, a disconnector spring, specialty set screws, a threaded roll pin, and an M4E1 lower bolt catch pin. Aero Precision makes every part in the USA, so shooters can carry one small kit and have what they need to get a rifle running again in the field instead of packing a dozen loose spares.
