Atrius Development Group ADG-FRS-S-MS Compatible w/ Mil-Spec AR15 223/5.56/300 BLK AR-15 Black Steel

The Mil-Spec Forced Reset Selector is machined from heat-treated 4140 steel with a corrosion-resistant 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 Full-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, the Atrius FRS's mechanically leveraged design reduces wear on the rifle's fire control group for improved longevity across high round-count use.The mil-spec style selector switch features traditional ergonomic ridges and a pointer that provide instant tactile thumb reference for position awareness under stress, eliminating fumbling and hesitation in fast-paced shooting scenarios.

Drop-in installation swaps out the factory safety in minutes with seamless integration into standard mil-spec full-profile AR-15 fire control groups requiring no modifications, while the single-side traditional design makes it a natural fit for retro builds and shooters who prefer a clean, classic lever profile.Aggressive texturing, chamfered edges, and purpose-built ergonomics give the thumb an immediate, sure purchase on the selector even under the most demanding conditions.

Atrius engineered the Mil-Spec Forced Reset Selector as a drop-in performance upgrade that combines the familiar look and feel of a traditional mil-spec safety 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 BLK ensures broad platform support without additional gunsmithing or parts replacement.

For AR-15 shooters who want a robust, USA-made forced reset selector with traditional mil-spec aesthetics and drop-in installation, the Mil-Spec Forced Reset Selector is a compelling upgrade.
