Product Info for OpticsPlanet Exclusive RISE Armament RA-240 Enhanced Rifle Trigger

If you're planning some AR modifications, the trigger is almost always the first change, so gear up with OpticsPlanet and RISE Armament with the exclusive RA-240 drop-in trigger. Working together, this single-stage trigger brings together Rise Armament's high quality designs and OP's unique style. The RA-240 is available in two colors and configurations. You'll find it in blue and black with a curved trigger shape, or silver and blue with a straight trigger shape.

These AR Triggers are designed with an extremely light 3.5-pound pull weight, crisp break, and fast reset. The RA-240 design was constructed from high-grade and heat treated tool steel and aluminum. For assembly, Rise Armament adheres to AS9100 aerospace requirements, which are much stricter than gun standards. Plus, the drop-in design is easy to install and requires no fine-tuning. It's also compatible with both .223- and .308-rifle designs. Upgrade with the Rise Armament RA-240 drop-in trigger, which you'll only find on OpticsPlanet!
