Atrius Development 3 Position Super Selector Safety The Atrius Development 3 Position Super Selector Safety is built for AR-15 owners who want a robust, fast-handling selector with three distinct modes for confident control. With a crisp 90-degree throw and positive detents, it delivers consistent engagement and quick transitions under stress. Precision-machined from heat-treated 4140 steel with a corrosion-resistant finish, it’s designed for hard use and long service life.

AR-15 Trigger & Selector Bundle – Rise RA-434 High Performance Trigger + Atrius Super Selector This bundle pairs two upgrades that noticeably improve how an AR-15 feels and runs at the controls: the Rise Armament RA-434 High-Performance Drop-In Trigger and the Atrius Development 3 Position Super Selector Safety. The RA-434 is a single-stage cassette trigger built for a smooth press and fast follow-up shots, featuring a 3.5 lb pull, quick reset, and nickel boron-coated internals for reduced friction. The straight trigger blade promotes consistent finger placement and a lighter-feeling pull.
