The Rise Armament RA-100 is a two-stage AR trigger designed to deliver reliable performance without the premium price tag. Built from S7 tool steel and finished in black nitride, this curved-lever trigger gives you the smooth, consistent pull of an upgrade trigger while maintaining the robust durability you need for duty use, competition, or high-round-count range sessions. Whether you're running an AR-15 or AR-10 with standard milspec small-pin dimensions, the RA-100 is engineered to handle steel-cased ammo, tough conditions, and shot-after-shot reliability.
The two-stage design breaks down into a light 1.5-lb. first stage and a crisp 3-lb. second stage, totaling approximately 4.5 lbs. of pull weight. That's noticeably smoother and easier to control than milspec, but the forceful hammer spring doesn't compromise on primer ignition—especially valuable if you're working with harder-to-fire ammunition. The reset is strong and tactile, giving you immediate feedback for faster follow-ups. Installation is straightforward: fewer moving parts than other component triggers mean no fussy disconnector assembly or tiny springs to lose. The included milspec hammer and trigger pins get you running with minimal fuss.
Heat-treated S7 tool steel with black nitride finish means the RA-100 stands up to heavy use and the elements without sacrificing durability for a lower price. This is a no-nonsense trigger for shooters who want better control and consistency without the duty-gun compromises—or the cost.
