  • Very happy with this trigger

    This is my first "good" trigger and it is very nice. Good pull and a nice positive reset. I will buy more as money allows.

  • Easy installation

    I am elderly with arthritic hands and nerve-damaged fingers. This RA-140 cassette style trigger is much easier to install for me than the two piece mil spec style trigger. Trigger action is light and crisp. No creep. Good reset, too.

  • Top Notch Quality Trigger, Affordable Price

    Posted by Cory Y on 13th Jun 2018

    This is the 3rd time I bought this trigger. I have it on all of my AR 15 and AR 10 platform rifles. Have not had any issues with this trigger whatsoever. Such a light and crisp break of the trigger and a really nice reset. And for the price of this trigger, definitely one of the best. Will continue to use this exact trigger

  • One of the best triggers on the market, hands down.

    The Rise Armament RA-140 Black Fallout Super Sporting Trigger is one of the best triggers on the market, hands down. You must note, however, that the set screws MUST be lowered into the lower receiver, or the trigger will rock ever so slightly, and you will get multiple ignitions from each pull of the trigger. Bad ju-ju. But, if you set the trigger up properly, it will serve you like it has served me, and be your favorite, like mine.
