ATRIUS AMBI FORCED RESET SELECTOR

The Atrius Ambidextrous Forced Reset Selector (FRS) is a premium upgrade for AR-15 platforms, delivering enhanced control, durability, and ambidextrous functionality in a robust three-position design. Featuring SAFE, SEMI, and FULL-SEMI positions, this selector provides advanced performance while maintaining intuitive operation.

Designed for seamless compatibility with mil-spec/full-profile AR-15 fire control groups chambered in .223/5.56 and .300 Blackout, the Atrius FRS installs as a drop-in replacement for your factory safety selector with no permanent modifications required.

Machined from heat-treated 4140 steel and finished with a corrosion-resistant coating, this selector is built to withstand harsh environments and heavy use. Its mechanically leveraged design helps reduce wear on internal components compared to traditional forced reset trigger systems, promoting long-term reliability.

The ambidextrous configuration allows for fast and efficient manipulation from either side of the rifle, while the 90-degree throw ensures crisp, positive engagement in every position. Aggressive texturing and ergonomic shaping provide confident control under stress, making it a strong choice for performance-driven builds.
