Rise Armament Advanced Performance AR-15 Single Stage Drop-In Trigger Group with Anti-Walk Pins

The Rise Armament RA-535 Advanced Performance Trigger is a single-stage drop-in trigger group engineered for shooters who demand a lighter, crisper pull and lightning-fast reset between shots. This AR-15 trigger fits most .223 and .308 AR-style platforms and arrives ready to install—no gunsmithing, fitting, or fine-tuning required. The self-contained design and included anti-rotation pins make it a straightforward swap that can noticeably sharpen your accuracy and speed at the range or in the field.

Built to aerospace-grade standards (AS9100—more stringent than standard firearms manufacturing specs), the RA-535 is precision CNC machined from high-grade heat-treated tool steel and aluminum, then housed in Rise Armament's signature bright red 8625 hardcoat anodized aluminum body. Every trigger is inspected with high-tech equipment capable of five-decimal-place accuracy, ensuring consistency well beyond what the human eye can verify. The result is a smooth, predictable release that helps you stay on target and cycle rounds faster.

The trigger combines a straight blade design with curved ergonomics, balancing control and comfort in your trigger finger. At 3.5 pounds of pull weight, it splits the difference between match-grade precision and practical field use. Whether you're running a precision rifle build, a duty carbine, or a hunting setup, the RA-535 offers a measurable improvement in trigger performance without the complexity of adjustable triggers or the cost of a full lower receiver swap.

Frequently Asked Questions

Will the RA-535 fit my AR-15 or AR-10?

The Rise Armament RA-535 is compatible with most .223 and .308 AR-style platforms. If you're unsure whether your rifle falls within that range, verify your caliber and platform before purchasing.

Does this trigger require gunsmithing to install?

No. The RA-535 is a self-contained drop-in trigger group designed for easy installation with no fitting or fine-tuning required. The anti-rotation pins are included to keep everything in place.

What's the pull weight, and is it adjustable?

The trigger has a 3.5-pound pull weight and is not adjustable. The pull is fixed at the factory and cannot be modified; any attempt to alter it will void the warranty.

What's included in the box?

The RA-535 comes with the trigger assembly and anti-rotation pins. You'll need standard AR-15 trigger pins (not included) to complete installation, though the anti-walk pins supplied will prevent pin walk once the trigger is in the lower.
