Rise Armament RA-100 Two-Stage Trigger

Rise Armament RA-100 Two-Stage Trigger

The Rise Armament RA-100 Two-Stage Trigger is built for shooters who demand precision and reliability from their rifle’s fire control group. Designed for both AR-15 and AR-10 platforms, the RA-100 combines the crisp feel of a single-stage break with the added control of a two-stage system. With a 1.5-lb. first stage and a clean 3-lb. second stage, this 4.5-lb. total pull weight offers ideal balance for competition, hunting, or tactical applications.

This trigger is precision-machined from S7 tool steel and treated with a black nitride finish for maximum strength and corrosion resistance. The simplified internal architecture of the RA-100 eliminates the need for a disconnector and tiny springs, which not only reduces potential failure points but also makes installation easier and more straightforward. It installs using standard mil-spec pins and fits seamlessly into small-pin .154″ lower receivers.

Whether you’re running .223, 5.56, or .308, the RA-100 delivers positive hammer strikes with its heavy-duty hammer spring. This added force helps ensure reliable ignition with even the toughest primers and surplus or steel-cased ammunition. If you’re running a duty-grade rifle or a competition-ready platform, the Rise Armament RA-100 Two-Stage Trigger is a high-performance upgrade that won’t compromise under pressure.

The RA-100 is proudly made in the USA and backed by Rise Armament’s lifetime warranty. It’s engineered with fewer moving parts than most two-stage triggers, making it one of the most durable and consistent options available in its class. Whether you’re precision shooting or working through drills at the range, this trigger delivers every time.

If you are new to building AR-15 or AR-10 rifles and have any questions about the Rise Armament RA-100 Two-Stage Trigger, we are always here to help!
