Atrius Development 3 Position Mil-Spec Style Super Selector Safety
The Atrius Development 3 Position Mil-Spec Style Super Selector Safety is built for AR-15 owners who want a traditional mil-spec look with expanded three-position functionality. This single-side selector uses a familiar mil-spec style switch with ergonomic ridges and a position pointer, making it a strong fit for retro-inspired builds as well as shooters who prefer classic controls. Atrius lists the selector as offering SAFE, SEMI, and SUPER-SEMI positions in a drop-in package designed for mil-spec and full-profile AR-15 fire control groups chambered in .223 / 5.56 / .300 BLK, with no modifications required.
Precision-engineered from heat-treated 4140 steel and finished in corrosion-resistant black nitride, this selector is designed for hard use and long service life. Atrius also notes that it is manufactured in the USA and ships in a black Atrius bag.
