CMMG 55AFF97 Mil-Spec AR-15 Trigger Kit Single Stage Curved

The CMMG 55AFF97 Mil-Spec Trigger Kit delivers consistent single-stage performance for AR-15 platform rifles. This drop-in replacement upgrade maintains military specification compatibility while providing improved trigger characteristics over standard GI triggers.

What Makes This Different

Unlike basic military triggers that often exhibit creep and inconsistent break points, this CMMG trigger assembly features precision-machined components with tighter tolerances. The single-stage design eliminates the traditional two-stage military feel, providing a more direct trigger pull. Factory testing ensures each trigger breaks cleanly between 4.5-8.5 pounds, meeting mil-spec requirements while delivering enhanced shootability.

Key Features

• Single-stage curved trigger face for consistent finger placement and pull angle
• Mil-spec dimensions ensure compatibility with all standard AR-15 lower receivers
• Heat-treated steel construction with anti-corrosion coating for extended service life
• Complete kit includes trigger, hammer, disconnector, and all necessary springs and pins
• 4140 steel hammer provides reliable primer strikes across various ammunition types
• Precision-ground sear surfaces reduce friction and improve trigger break consistency
• Drop-in installation requires no gunsmithing or permanent modifications

Field testing demonstrates reliable function across temperature extremes and high round counts. The trigger maintains consistent performance in competitive shooting environments, tactical applications, and hunting scenarios. Shooters report improved accuracy potential due to the predictable break and minimal overtravel. The mil-spec trigger pull weight range accommodates both precision shooting and rapid-fire applications.
