The Rise Armament Rev 535 Slide-and-Snap Single-Stage AR Trigger installs in under 60 seconds to provide a smooth 3.03.5 lb. pull with no take-up and lightning-fast reset. Compatible with standard mil-spec lowers, the Rev 535 simply slides in and snaps into place often without needing to remove the grip or safety selector. The built-in pins mean you don't have to deal with loose hardware, set screws, or threadlocker. It's a true drop-in design that couldn't be easier. But it's the performance and versatility where the Rev 535 Single-Stage AR Trigger really shines. In addition to the remarkably smooth pull, the trigger comes with multiple shoes that lock into place with TorLok technology, allowing you to change the feel in seconds. Based on the legendary RA-535, the Rev 535 delivers the same ultra-crisp, no-take-up pull and tactile reset you can feel and hear. That means improved accuracy, faster return to target, and more confident follow-up shots. The housing is precision-machined from 6061 aluminum and anodized for durability. Internal components are made from nickel boron-coated, heat-treated S7 tool steel. Backed by Mfrs. lifetime limited warranty.
