Description

Atrius Forced Reset Selector for AR-15 Rifles

The Atrius Forced Reset Selector (FRS) offers an alternative to traditional forced reset trigger systems by providing a three-position selector that installs in place of the factory AR-15 safety selector.

Designed for compatible AR-15 rifles chambered in .223 Remington, 5.56 NATO, and .300 Blackout, the Atrius FRS is a purpose-built upgrade for owners seeking a durable, reliable, and easy-to-install selector system. Unlike traditional forced reset trigger assemblies that require extensive component replacement, the Atrius FRS replaces the factory safety selector while maintaining compatibility with standard lower receiver components.

The mechanically leveraged design works with compatible fire control groups while reducing wear on critical internal components. The result is a streamlined solution engineered for long-term reliability and consistent performance.

Precision-machined from heat-treated 4140 steel and protected by a corrosion-resistant black nitride finish, the Atrius FRS is built to withstand demanding conditions. Rain, mud, dust, sweat, and hard use are no match for its rugged construction.

The aggressive textured selector profile provides positive engagement and rapid manipulation under stress, while the traditional left-side selector layout offers a familiar feel for shooters accustomed to standard mil-spec controls.
