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.

Designed for mil-spec AR-15 fire control groups in .223/5.56/.300 BLK, this selector installs as a drop-in replacement for most builds, though minor fitment may be required depending on receiver tolerances.
