Atrius Development Ambidextrous Mil-Spec Forced Reset Selector Features The Ambidextrous Mil-Spec Forced Reset Selector is machined from heat-treated 4140 steel and coated in a corrosion-resistant black nitride finish delivering hardcore durability that withstands rain mud sweat and sustained range use without wear or degradation to the selector s engagement geometry. The 3-position forced reset selector provides Safe Semi and Super-Semi positions with crisp tactile 90-degree throw clicks and positive positioning that eliminates unintentional movement mid-fire for full control at all times. Unlike forced-reset triggers that accelerate internal component degradation this mechanically leveraged design reduces wear on the rifle s fire control group for improved longevity across high round-count use. The mil-spec style switch features traditional ergonomic ridges and a pointer on both sides providing instant tactile thumb reference for position awareness under stress whether operated from the right or left side of the rifle making it especially well suited for left-handed shooters. Drop-in installation swaps out the factory safety in minutes with seamless integration into standard mil-spec fire control groups without a relief cut as well as a wide variety of single-stage drop-in and cassette style triggers requiring no modifications or trigger cutting. For shooters who need dependable ambidextrous manipulation without gunsmithing this drop-in compatibility and mil-spec ergonomics deliver a natural familiar feel under stress. Atrius Development engineered the Ambidextrous Mil-Spec Forced Reset Selector as a drop-in performance upgrade that combines familiar mil-spec ergonomics with the mechanical advantages of a forced reset selector in a 4140 steel package proudly manufactured in the USA. Compatibility with standard mil-spec AR-15 fire control groups in .223/5.56/.300 Blackout ensures broad platform support without additional gunsmithing or parts replacement. For AR-15 shooters who want a robust USA-made ambidextrous forced reset selector with drop-in installation this selector is a compelling upgrade for both right and left-handed users.
