Colt M4 AR-15 Field Repair Kit 19 Piece

Colt's field repair kit gathers the small parts that wear out or go missing on an AR-15 or M4: 19 pieces in all, from the same maker that built the original rifles for the military.

The kit covers springs, pins and detents such as the trigger and hammer springs, bolt catch parts, takedown pin detents, the selector detent, the buffer retainer and its spring, and the firing pin with its retaining pin. Toss it in a range bag or a go bag for repairs away from the bench.
