ATRIUS AMBI FORCED RESET SELECTOR G-LEVER (GEISSELE)

The Atrius Development Group G-LEVER Ambidextrous Forced Reset Selector (FRS) is a next-generation fire control upgrade engineered for enhanced control, durability, and performance on AR-15 platforms. Designed with a unique three-position configuration—SAFE, SEMI, and SUPER-SEMI—the G-LEVER delivers advanced functionality while maintaining familiar operation.

Built for compatibility with Geissele triggers including SSA, SSA-E, and G2S (excluding X Series), the G-LEVER also integrates seamlessly with mil-spec AR-15 fire control groups chambered in .223/5.56 and .300 Blackout without modification.

Constructed from heat-treated 4140 steel and finished with a corrosion-resistant coating, this selector is built to withstand hard use in demanding conditions. The included aluminum Lever Blocker, finished in black nitride, prevents over-rotation and ensures consistent, reliable function.

Unlike traditional forced reset triggers, the G-LEVER uses a mechanically leveraged design that helps reduce internal wear while maintaining smooth, consistent engagement. The 90-degree throw provides crisp, positive selector positions, while aggressive texturing and ergonomic shaping allow fast, confident manipulation under stress.

Designed for quick installation, the G-LEVER replaces your factory safety selector with minimal effort, delivering a robust and refined upgrade for serious shooters.
