Description
Rise Armament built its name on this trigger, and it's easy to see why. The RA-535 Advanced Performance Trigger delivers a smooth, single-stage 3.5 lb pull with a super-crisp break and a reset so short you'll feel the difference on your very first string. Rise leans on aerospace-grade machining here, CNC-cutting the internals from heat-treated tool steel and aluminum, then wrapping everything in that signature red 8625 hardcoat anodized housing that looks as good as it shoots.
What Sets the RA-535 APT Apart
The magic is in the details. There's essentially no take-up before the sear engages, so the pull starts right where you want it. Over-travel is nearly nonexistent, meaning the trigger stops almost the instant the round breaks, and that quick reset lets you get back on target in a hurry. Rise coats the internal parts with Nickel Teflon, which actually gets smoother the more rounds you send through it. The trigger blade itself blends the feel of a straight face with the comfort of a curve, giving your finger a natural, repeatable resting spot shot after shot.
Drop-In Simple, Built to Last
This is a self-contained unit, so there's no fine-tuning or fiddling with individual springs and pins. Punch out your old trigger, drop this one in, secure it with the included anti-rotation pins, and you're done. Those pins are a nice touch too, since they keep everything locked in place during long strings of fire where standard pins can work loose. It fits into most mil-spec AR lowers and plays nice across common calibers like .223/5.56, .300 BLK, .308, and 6.5 Creedmoor, so it's just as at home in an AR-10 build as it is an AR-15.
Who's Reaching for the RA-535
Competition folks were early adopters of this one, and it's earned a loyal following among precision and 3-gun crowd for good reason. Repeat buyers are common, with plenty of people running two or three of these across different builds. If you're upgrading a factory trigger and want a genuine performance jump without the headache of a tuned custom setup, the RA-535 APT is a proven pick.

Frequently Asked Questions
What rifles does the RA-535 APT fit?
The RA-535 drops into most mil-spec AR lowers and fits both AR-15 and AR-10 platforms. It works across common calibers including .223/5.56, .300 BLK, .308, and 6.5 Creedmoor. Keep in mind it's designed for mil-spec receivers, so non-mil-spec lowers may not accept it correctly.
Is the Rise Armament RA-535 hard to install?
Not at all. It's a self-contained drop-in unit, so you punch out your factory trigger, set the RA-535 in place, and secure it with the included anti-rotation pins. There's no spring fiddling or fine-tuning required, and most folks have it done in a few minutes.
What makes the RA-535 pull feel different from a standard trigger?
It's a single-stage 3.5 lb pull with virtually no take-up before the sear engages, so the trigger starts moving right where you want it. The break is crisp, over-travel is nearly gone, and the reset is very short. The internal Nickel Teflon coating also smooths out further the more you shoot it.
Does the RA-535 work with a 45-degree safety selector?
Yes, Rise Armament triggers are compatible with a 45-degree ambidextrous or short-throw safety selector. That makes it a solid match for competition and tactical builds running upgraded controls.
