Rise Armament RA-100 Two-Stage AR Trigger, Curved, Black

Rise Armament RA-100 Two-Stage Trigger

The RA-100 is a purpose-built AR trigger that bridges the gap between standard milspec performance and premium aftermarket options. Designed for shooters who demand reliability without paying for unnecessary frills, this trigger delivers measurable improvements in control, consistency, and ease of use.

Performance You Can Feel

The two-stage design breaks down into a smooth 1.5-pound first stage and a crisp 3-pound second stage, totaling a 4.5-pound pull. This geometry improves trigger control and helps newer shooters develop better fundamentals while giving experienced marksmen the predictability they expect. The reset is strong, fast, and distinctly tactile—you'll feel and hear it, which translates to faster, more confident follow-up shots.

Built for Real-World Conditions

Rise engineered the RA-100 with a forceful hammer spring that delivers hard, reliable primer strikes even with steel-cased ammunition. The precision-machined S7 tool steel construction is heat-treated and finished with black nitride for maximum durability and corrosion resistance. This is a trigger that handles tough conditions shot after shot without compromise.

Simple Installation

Unlike complex component triggers with intricate disconnector assemblies and tiny springs, the RA-100 installs straightforwardly. Fewer parts mean fewer things to go wrong. Secure it with the included milspec hammer and trigger pins, and you're ready to shoot.
