CMC Triggers AR-15 Lower Parts Replacement Kit Features The CMC Triggers kit bundles the exact small parts that most often launch across the shop floor during an AR-15 lower build. Included are one buffer retainer with two springs four takedown and pivot pin detents with six springs two selector detents with two springs two disconnector springs and two bolt catch springs with one detent. Because the kit carries extras of nearly every part a builder who loses a detent or two does not need to stop and order a single replacement piece. Keeping this kit on the bench means a lower build can continue the same day a small part gets away. Every piece in the kit is built to the same fit and function as the originals it replaces so there is no compatibility guesswork when reassembling an AR-15 lower receiver. The finish is black to match the small parts it is designed to replace and the full assortment covers the buffer takedown selector disconnector and bolt catch systems in one package. For an armorer servicing multiple rifles or a builder assembling several lowers this kit removes the need to stock each spring and detent separately. It is a simple practical addition to any AR-15 builder s bench that pays for itself the first time a detent goes missing.
