Rise Armament RA-535 Trigger

Product Description

The Rise Armament RA-535 Trigger is a self-contained drop-in trigger assembly for AR-15 platform rifles. It replaces the factory trigger group to deliver a lighter, crisper trigger pull with minimal take-up and a clean break.

This trigger is built for shooters who need consistent, repeatable trigger control in precision rifle setups and competition builds. The self-contained cassette design simplifies installation and eliminates the need to fit individual springs and pins.

Whether you’re upgrading a precision AR or building a competition rifle from scratch, the RA-535 brings measurable improvements to trigger feel and reset characteristics.

How the RA-535 Compares to Mil-Spec Triggers

Mil-spec AR triggers typically have gritty, heavy pulls with noticeable creep and stacking. Drop-in trigger assemblies like the RA-535 eliminate those issues with precision-machined components and tuned springs installed inside a self-contained housing.

The result is a pull weight you can trust shot after shot, with minimal overtravel and a short, tactile reset. That consistency matters most when you’re shooting groups at distance or engaging multiple targets under time pressure.

Because the RA-535 is a cassette-style unit, you don’t need to install disconnectors, springs, or hammer pins individually. The entire assembly drops into the lower receiver as one piece.

Installing the RA-535 in an AR-15 Lower

The RA-535 is designed to fit standard AR-15 lower receivers without modification. You remove the factory trigger group, safety selector, and grip, then install the cassette trigger assembly in its place.

Anti-walk pins or anti-rotation pins are commonly used with drop-in triggers to prevent pin migration under recoil. The RA-535 uses a cassette design, so confirm pin compatibility and spacing before installation. If you’re unsure about fitment or want a professional install, our gunsmithing team at Western Sport can handle the swap.

Most AR builders with basic tools can complete the installation in under thirty minutes. If you’re assembling a complete lower or need lower parts for your build, we stock the components you need.

What to Know Before Buying the RA-535

The RA-535 is intended for use in semi-automatic AR-15 rifles. It is not recommended for full-auto or select-fire applications unless specifically approved by the manufacturer for that purpose.

Pull weight, reset distance, and compatibility details should be confirmed before purchase. Send us a message to verify specs and confirm this trigger will work in your specific lower receiver.

Like all aftermarket triggers, the RA-535 may require sight-in or zero confirmation after installation, especially if you’re switching from a significantly heavier factory trigger. Take time at the range to familiarize yourself with the new pull weight and reset before using the rifle in competition or defensive scenarios.

Q: What is the pull weight on the RA-535 trigger?

Drop-in AR triggers generally range from 3 to 4.5 pounds, but verify the exact specification for this model before purchasing.

Q: Can I install the RA-535 myself or do I need a gunsmith?

A: Most AR builders with basic tools and experience can install a drop-in trigger like the RA-535 at home. If you’re new to AR builds or prefer a professional installation, Western Sport offers gunsmithing services.

Q: How does the RA-535 compare to single-stage mil-spec triggers?

A: Mil-spec AR triggers are typically heavier and have more creep than aftermarket drop-in units. The RA-535 offers a lighter, cleaner break with less take-up and a shorter reset, which improves consistency for precision shooting and competitive use. The self-contained cassette design also simplifies installation compared to loose trigger parts.

Q: Is the RA-535 legal in Texas and other states?

A: The RA-535 is a standard semi-automatic trigger and is legal for civilian use in Texas and most other states. It is not a forced-reset trigger or binary trigger. Always verify compliance with local and state laws before purchasing any firearm part.
