Rise Armament RA-434 Flat Trigger Single Stage AR-15 Platform

The Rise Armament RA-434 delivers precision trigger control with its single-stage flat design, engineered for AR-platform rifles. This high-performance trigger system reduces reset distance and provides consistent pull weight for improved accuracy and faster follow-up shots.

What Makes This Different

The RA-434 features a precision-machined flat trigger face that promotes consistent finger placement and straight-back trigger pull. Unlike traditional curved triggers, the flat profile distributes pressure evenly across the finger pad, reducing side-to-side movement that can affect shot placement. The single-stage design eliminates the two-stage travel found in mil-spec triggers, providing immediate engagement with minimal overtravel.

Key Features

• Single-stage flat trigger with 3.5-4.5 lb pull weight range
• Precision-machined from aircraft-grade aluminum and tool steel
• Anti-walk pins included to prevent trigger movement in receiver
• Compatible with standard AR-15/AR-10 lower receivers
• Nickel boron coating on internal components for corrosion resistance
• Adjustable overtravel screw for customized trigger stop
• Drop-in installation requires no gunsmithing or permanent modifications

The RA-434 maintains consistent performance across temperature extremes and high round counts. Competition shooters benefit from the reduced reset distance and crisp break, while tactical applications gain reliability through the robust construction and corrosion-resistant finish. The trigger's design minimizes lock time between trigger pull and firing pin release, contributing to improved accuracy potential.
