Rise Armament Combo Kit – RA-434 Trigger w/ 6423 Black Ambi Safety Selector
The Rise Armament Combo Kit pairs the RA-434 High-Performance Trigger with the 6423 Black Ambidextrous Safety Selector for a straightforward AR upgrade focused on cleaner trigger feel and faster control input. The RA-434 is built as a self-contained drop-in unit with a crisp single-stage break, quick reset, and friction-reducing nickel-boron-coated internals, while the 6423 selector adds ambidextrous handling with a fast 69-degree throw. Together, they create a practical lower upgrade for shooters who want smoother trigger performance, positive selector engagement, and easier installation in one package.
