The design of the Colt Fire Control Repair Kit SPK99795 integrates an OEM single-stage trigger and hammer assembly for standard small-pin AR-15 platforms. This replacement configuration includes all corresponding mil-spec springs, the disconnector, and two hardened receiver pins required for a complete lower receiver overhaul. The construction utilizes high-strength, heat-treated carbon steel finished in a corrosion-resistant matte coating to ensure long-term mechanical longevity under high round counts. Operating strictly within factory specifications, this drop-in kit restores a clean, predictable trigger break and a rapid reset to worn lower receivers. This model serves as a necessary maintenance collection for competitive shooters, tactical instructors, and field armorers seeking to maintain combat-grade weapon performance.
