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

The Rise Armament RA-535 Advanced Performance Single Stage AR Rifle Trigger is a 3.5 lb curved-blade option built for shooters who demand a crisp, predictable break without the guesswork of take-up. This is a single-stage trigger purpose-built for AR platforms—designed for hunters, competition shooters, and range enthusiasts who want to tighten groups and speed up follow-up shots. The curved blade face suits many hand sizes and shooting styles, making it a versatile choice for general-duty accuracy work.

What sets the RA-535 apart is the engineering inside. The internals use S7 tool steel components with Nickel Boron coating for smooth operation and long-term reliability. The hammer is lighter than standard mil-spec designs but engineered to deliver full strike energy for consistent primer ignition. The housing is machined from 6061 aerospace-grade aluminum billet—precision-made for strength and consistency. You get a no-take-up break (trigger movement starts at the sear, with no slack), a tactile reset you can feel and hear, and the mechanical advantage of a single-stage pull.

Installation is straightforward on compatible mil-spec AR lowers. The design allows for quick setup without requiring extensive tool work or lengthy gunsmithing. Once installed, the RA-535 is at home on a hunting rifle, a 3-gun competitor's AR, or a precision rifle used for load development and accuracy testing.
