Rise Armament RA-535 Advanced Performance Single Stage AR Rifle Trigger 3.5 lb Curved Black$269.99
Availability: In Stock
The Rise Armament RA-100 two-stage trigger is built for shooters who want more control and reliability than a standard milspec trigger without paying premium prices. This AR-15/AR-10 trigger combines a lighter, crisper pull with a forceful hammer spring designed to reliably ignite primers even with steel-cased ammunition—a real advantage if you shoot budget loads at the range or rely on surplus ammo in the field. The two-stage design breaks down into a smooth 1.5-lb. first stage that transitions into a clean 3-lb. second stage, totaling approximately 4.5 lbs. of pull weight. That translates to faster, more confident follow-up shots without the mushy, unpredictable feel of a worn milspec trigger.
What sets the RA-100 apart is how straightforward it is to install. Unlike some aftermarket triggers that demand fussy alignment or oddball disconnector assemblies, this one uses a simplified component layout with standard milspec small-pin dimensions. You get the included hammer and trigger pins, and installation is a matter of minutes for anyone comfortable working on an AR. The trigger itself is precision-machined from S7 tool steel, heat-treated for strength, and finished in black nitride to resist corrosion—no cast components here, which means it'll hold up through years of hard use at the range or in the field.
Whether you're tuning a precision rifle, upgrading a duty gun, or just tired of a gritty factory trigger, the RA-100 delivers genuinely improved control and reset feel. The reset is strong, tactile, and fast—you'll feel and hear it clearly, which helps you stay on target during rapid-fire strings. Rise backs the trigger with a lifetime warranty, so you can install it and forget about it.
