ABSTRACT:
Apparatus for a modular fire control assembly for a firearm. The modular fire control assembly integrates a hammer, a sear, a disconnector, and sear and disconnector springs in a single housing. The force applied by the sear spring is adjustable by a set screw, which enables the sear spring force to be dialed in. The sear spring and set screw are contained in a block in the housing. The sear spring engages a detent that applies spring force to the sear. The sear spring moves in a smooth bore that has a ledge that allows the spring to maintain a minimum force even when the set screw is removed. A self-contained disconnector spring ensures constant spring force on the disconnector regardless of adjustments to the sear spring force. The modular assembly is configured to be received in a lock cavity of the firearm and secured using conventional pins.
