Atrius Development 3 Position Super Selector Safety with Rise Armament RA-434 Drop-In Trigger

This AR-15 upgrade bundle combines the Atrius Development 3 Position Super Selector Safety with the Rise Armament RA-434 High-Performance Drop-In Trigger for shooters who want faster control input and a cleaner trigger press in one package. The selector brings three distinct modes with a positive 90-degree throw, textured levers, and solid tactile engagement, while the RA-434 adds a smooth single-stage break, quick reset, and light 3.5-pound pull weight for improved speed and consistency.

Together, these parts create a straightforward upgrade for compatible Mil-Spec AR-15 platforms in .223, 5.56, and .300 Blackout, with the trigger also fitting most .308 and .223 AR-style builds. Both components are designed for easy installation, durable hard use, and dependable performance, making this a practical bundle for builders looking to improve handling, responsiveness, and overall shooting feel.
