Atrius Development 3 Position Super Selector G-LEVER Ambidextrous Safety - ADG-FRS-AMBI-G

Our most robust Forced Reset solution on the market that enables the user to have 3 positions; SAFE, SEMI (Traditional) and SUPER-SEMI — is now compatible with Geissele Triggers!

The G-LEVER is an Ambidextrous FRS that comes with a Lever Blocker designed to keep your cam lever from over-rotating beneath the trigger group’s hammer. The Lever Blocker is made of aluminum and is black nitrided to combat wear or corrosion.

Atrius Development Group’s G-LEVER is compatible with Geissele SSA, SSA-E, and G2S triggers. (Please Note: The Geissele “X Series” are currently not compatible)

Atrius Forced Reset Selectors (FRS) are compatible with mil-spec/full-profile AR15 (chambered in .223/5.56/.300 BLK) fire control groups with no modifications required.

PRODUCT FEATURES

• Drop-In Installation – Swap out your factory safety in minutes and experience the next level of firearm manipulation (some fitment may be required).
• Runs with Mil-Spec Fire Control Groups – Seamlessly integrates with standard AR fire control groups, ensuring flawless function and longevity without modification.
• Hardcore Durability – Crafted from heat-treated, 4140 steel and coated in a corrosion-resistant finish, the Atrius FRS laughs in the face of wear and tear. Rain, mud, sweat—it eats it all for breakfast.
• Mechanically Leveraged Design – Our Forced Reset Selector (FRS) reduces wear on your rifle, preserving your weapon’s longevity — unlike forced-reset triggers (FRTs) that accelerate internal component degradation.
