- Product Code: RA-535-RED-ARP
Rise Armament RA-535 AP-Trigger is a single-stage, cassette-type drop-in trigger mechanism designed for AR-15 and AR-10 platforms, aimed at improving accuracy and facilitating control over rapid follow-up shots; the manufacturer describes the model as Advanced Performance Trigger level and even with the phrase The Ferrari of Triggers. The description boils down to the shooter staying on target more easily and follow-up shots happening faster, which is based on the extremely fast reset, virtually non-existent pre-travel, and clear, crisp break.
The cassette-style unit is structurally easy to install without permanent modifications to the receiver, and it is compatible with small-pin AR receivers. The trigger pull weight is typically around 1.6 kg (3.5 lb), providing a stable feel and repeatable trigger pull. The short travel and fast reset minimize the time between shots and the next pull, while the creep is practically non-existent, ensuring a clean and predictable break.
The cassette housing is machined from aluminum and anodized for a durable finish, and the internal components are made from hardened tool steel. The contact surfaces are precisely finished to ensure low friction and to provide the cleanest possible trigger feel. The unit is delivered as a drop-in solution, and it is typically used with anti-walk pins to ensure a secure installation. The manufacturer's Why You’ll Love It points emphasize Lightning-Fast Reset, Virtually Zero Creep, and Flawlessly Crisp Break, which describe the product's performance neutrally yet concisely.
