Rise Armament RA-100F Two-Stage Flat Trigger – RA-100F

Designed for durability, reliability, and value, the RISE RA-100 Flat is a workhorse two-stage AR trigger that elevates performance above mil-spec expectations. Precision-machined from S7 tool steel and finished in black nitride, this trigger delivers consistent, long-term durability and a smooth, crisp break ideal for duty, competition, and serious range use.

The RA-100 Flat uses a flat trigger blade and a two-stage pull for predictable control. The first stage measures 1.5 pounds and transitions to a clean three-pound second stage, producing a tactile, audible, and repeatable reset for faster follow-up shots. A robust hammer spring ensures strong primer strikes, including reliable ignition with steel-cased ammunition, and the overall design is profiled to withstand heavy use.

Installation is straightforward. The trigger employs a simplified parts set with no fiddly disconnector assembly or tiny springs to lose, and includes mil-spec hammer and trigger pins for secure fitment. With fewer components than many competitive units, the RA-100 Flat reduces installation complexity while maintaining a rock-solid interface with the fire control group.

Built for hard use and harsh environments, this trigger combines refined ergonomics, dependable function, and durable materials to deliver a professional-grade trigger package at a practical price point.
