Rise Armament Combo Kit – RA-535 Black Trigger w/6423 Black Ambi Safety Selector
The Rise Armament Combo Kit pairs the RA-535 Black Trigger with the 6423 Black Ambidextrous Safety Selector for shooters who want a smoother trigger press and faster control input in one upgrade package. The RA-535 uses a self-contained single-stage design with a crisp 3.5-pound pull, a fast Quik-Klik reset, and a clean break to help improve speed and consistency. Paired with the 6423 ambi safety, this kit gives AR builders a simple way to upgrade both trigger feel and selector handling at the same time.
Built from quality materials for hard use, the trigger uses heat-treated tool steel and aluminum with a durable anodized housing, while the selector adds ambidextrous control for easier manipulation from either side of the rifle. This combo is a strong fit for shooters upgrading a mil-spec style lower across a wide range of AR-platform calibers.
