RISE LE145 Tactical AR-15 Trigger - Single-Stage, 4.5 lb Pull

The RISE LE145 Tactical AR-15 Trigger is a single-stage upgrade designed for shooters who demand a crisp, predictable break when it matters. Built to Rise Armament's aerospace-grade manufacturing standards, this 4.5 lb pull trigger combines reliability with genuine shootability—whether you're running drills at the range, hunting, or training for duty applications. Drop-in installation and a self-contained design mean you skip the gunsmithing and get behind steel faster.

Rise machines the LE145 from high-grade heat-treated tool steel and aluminum, then hard-coats the cassette to military specs. The result is a trigger group that handles repeat firing without the creep or mushiness you'll find in factory mil-spec parts. The rounded trigger shoe fits naturally, and the balanced break rewards good trigger control with audible and tactile feedback. A drop safety keeps the hammer secured during handling and carry, so you get security along with performance.

Fit matters: the LE145 is engineered for most .308 and .223 AR-pattern rifles. Because it's fully self-contained, there's no staking, polishing, or spring manipulation needed—drop it in, pin it down (Rise recommends KNS pins for best results), and go. At 2.6 oz, it adds negligible weight to your upper assembly. This is the trigger for AR owners who refuse to compromise between precision and reliability.
