The RISE Rev 535 is a second-generation drop-in AR trigger built on the proven RA-535 APT platform, adding a completely redesigned installation system and interchangeable blade faces to an already class-leading performance package. On compatible mil-spec lowers, the Rev 535 slides into place and locks in under 60 seconds - no tools, no loose hardware, no set screws. Built-in integrated pins provide anti-walk and anti-rotation security without the headaches of traditional component installs. This configuration ships with a silver blade base and two red blade faces - one flat, one curved - giving you the option to dial in trigger feel without any additional purchases. Blade faces swap in seconds via TorLok technology, a combination of mechanical engagement and magnetic retention that holds the face securely without tools. Under the housing, heat-treated S7 tool steel internals with a Nickel Boron coating deliver smooth, low-friction operation and long-term wear resistance, while a precision-machined 6061 aerospace aluminum housing keeps tolerances consistent. The single-stage pull breaks cleanly with zero take-up from the NoWay system, and the Quik-Klik reset is short, audible, and tactile. Backed by RISE's Lifetime Manufacturing Warranty and the More-Bang-for-Your-Buck Performance Guarantee - if it doesn't deliver, RISE buys it back.
