The RISE Rev 535 Slide-and-Snap AR Trigger represents a next-generation approach to AR trigger upgrades-one that not only saves you time but also reduces hassle while still delivering the performance you expect from RISE. To begin with, on compatible mil-spec lowers, the Rev 535 simply slides into place and installs in under 60 seconds, often without removing the grip or safety selector. Moreover, built-in pins for rapid installation eliminate loose hardware, tools, set screws, and threadlocker, all while still providing reliable anti-walk and anti-rotation security. As a result, you spend less time installing and more time shooting.
