Rise Armament RA-434 Single Stage Flat Trigger 3.5lb AR-15

The Rise Armament RA-434 delivers precision trigger control with a crisp 3.5-pound pull weight designed for competitive shooting and tactical applications. This single-stage flat trigger eliminates the mushy feel of mil-spec triggers while maintaining reliability standards required for duty use.

What Makes This Different

Unlike standard mil-spec triggers that stack weight and exhibit creep, the RA-434 breaks cleanly at 3.5 pounds with minimal overtravel. The flat trigger face provides consistent finger placement across different hand sizes and shooting positions. Rise Armament machines each component from tool steel with precise tolerances that eliminate trigger slap and reduce lock time by 40% compared to factory triggers.

Key Features

• Single-stage flat trigger with consistent 3.5-pound pull weight
• Tool steel construction with black nitride and silver finish combination
• Anti-walk pins included to prevent trigger movement in receiver
• Compatible with all AR-15 and AR-10 lower receivers
• Reduced overtravel and reset distance for faster follow-up shots
• Drop-in installation requires no gunsmith modifications
• Mil-spec dimensions maintain reliability with standard bolt carriers

Competitive shooters report improved split times due to the shortened reset and consistent break point. The flat trigger face distributes pressure evenly across the finger pad, reducing the tendency to push shots left or right under stress. Law enforcement agencies have adopted this trigger for precision rifle platforms where accuracy demands exceed mil-spec capabilities. The nitride finish resists corrosion in humid environments while maintaining smooth operation through temperature extremes.
