Rise Armament Law Enforcement & Military AR-15 Single Stage Drop-In Trigger Group w/ Anti-Walk Pins - Black

The Rise Armament LE145 is a single-stage AR-15 drop-in trigger designed for shooters who demand reliability under pressure. Whether you're running a duty rifle, building a precision platform, or upgrading a hunting AR, this trigger delivers a crisp, predictable break without the fuss of a custom install. The fully self-contained design drops straight into your lower receiver—no gunsmithing, no special tools, no fine-tuning required.

Built around a 4.5-pound pull weight, the LE145 strikes a balance between control and responsiveness. The single-stage design means one clean break from takeup to reset, which translates to faster target reacquisition and more consistent shot placement. The rounded trigger shoe encourages a proper press while the hardened aluminum cassette stands up to the abuse of serious use. A drop safety adds an extra layer of security, and the inclusion of anti-walk pins means your trigger stays put without the need for additional hardware tweaks.

Rise Armament engineered this trigger for .223 and .308 AR platforms, so whether you're running a modern sporting rifle or a precision long-range build, compatibility isn't a question. At just 2.6 ounces, there's no weight penalty. The black 8625 hardcoat anodized finish resists corrosion and wear, holding up through countless rounds and rough handling. If you're not using KNS pins, simply follow the included installation instructions to secure the cassette properly—the process takes minutes.
