Rise Armament RA-535 Advanced Performance Single Stage AR Rifle Trigger 3.5 lb Curved Red

The Rise Armament RA-535 Advanced Performance single-stage AR trigger is built for shooters who demand a crisp, predictable break without the learning curve of a heavy pull. At 3.5 pounds, this curved-blade trigger delivers the no-take-up, ultra-fast reset that makes follow-up shots snap back on target—whether you're running drills at the range, competing, or hunting. The RA-535 uses premium NiB-coated S7 tool steel internals and a precision-machined 6061 aerospace aluminum housing, so you get smooth operation and durability that holds up to serious use.

What sets the RA-535 apart is how it goes into your lower. This trigger slides and secures using built-in pins—no loose hardware, no threadlocker, no fussing with set screws. Installation takes under 60 seconds on mil-spec lowers and often doesn't require removing your grip or safety selector. The interchangeable blade faces (flat and curved included) attach via TorLok technology, which combines mechanical engagement with magnetic retention, so you can swap feels without tools and without disassembly. Even run it blade-base-only if you want; it stays fully functional.

Performance hinges on what RISE calls the no-take-up principle: trigger movement starts at the sear, not before. Combined with the Quik-Klik tactile reset and a LiteMite hammer design that maintains consistent strike energy despite reduced mass, you get tight groups and reliable ignition. The Heavy-Hit hardening on S7 internals ensures that primer strikes stay consistent shot after shot, and the NiB coating keeps friction low and wear resistance high—important if you're logging serious rounds.

The RA-535 comes backed by a Lifetime Manufacturing Warranty and RISE's Performance Guarantee. If it doesn't deliver a clean break, zero take-up, and a fast reset, they'll buy it back.

Frequently Asked Questions

What AR lowers is the RA-535 compatible with?

The RA-535 is designed to work with mil-spec AR lowers and installs via the Slide-and-Snap mechanism, which secures using built-in pins.

How long does installation take?

Installation takes under 60 seconds on compatible mil-spec lowers. In most cases, you won't need to remove your grip or safety selector, and there are no loose parts, set screws, or threadlocker required.

Can I swap between the curved and flat blade faces?

Yes. Both a curved (red) and flat blade face are included. They attach using TorLok technology—mechanical and magnetic retention—so you can change them in seconds without tools or disassembly. The trigger also functions fully on the blade base alone if you prefer.

What makes the reset so fast on the RA-535?

The RA-535 features the Quik-Klik trigger reset system, which is short, audible, and tactile. Combined with the LiteMite hammer design (reduced mass with full strike energy) and the no-take-up break, the result is a lightning-fast return to target for rapid follow-up shots.
