CMC Triggers 91505 Drop-In Single Stage Curved AR-15 Trigger 3.5lb

The CMC Triggers 91505 delivers consistent 3.5-pound pull weight with zero creep, transforming standard AR-15 performance through precision-machined components. This drop-in trigger assembly eliminates the guesswork of individual part installation while maintaining reliability across thousands of rounds.

What Makes This Different

Unlike mil-spec triggers with their gritty 6-8 pound pull weights, the 91505 features a self-contained design with pre-set sear engagement. The single-stage operation provides immediate break without the two-stage delay, while the curved trigger face maintains familiar ergonomics. Factory testing ensures each unit meets the 3.0-3.5 pound specification before shipping.

Key Features

• Drop-in installation requires no gunsmithing or individual component timing
• Single-stage design with crisp break and minimal overtravel
• 3.0-3.5 pound pull weight with consistent reset
• Heat-treated 8620 steel construction with black nitride finish
• Self-contained trigger, hammer, and disconnector assembly
• Compatible with standard AR-15 lower receivers and .154" trigger pins
• Curved trigger face matches mil-spec ergonomics

Range testing demonstrates reliable function across various ammunition weights and powder charges. The consistent break point improves accuracy for precision shooting applications, while the reduced pull weight decreases fatigue during extended training sessions. The nitride finish resists corrosion and wear under adverse conditions, maintaining smooth operation through temperature extremes and high round counts.
