Experience Superior Firearm Control with Atrius Ambi Selector FRS Kit

Artius Development Group introduces the Atrius Ambi Upgrade Kit for Forced Reset Selectors, enabling users to convert single-side selectors into ambidextrous versions. The upgrade promises quick installation, robust durability, and enhanced firearm control. It features a smooth engagement mechanism and is compatible with mil-spec AR15 fire control groups, available for a limited time.

Artius Development Group states “Introducing the Atrius Ambi Upgrade Kit, a steal of a deal, it’s our way of thanking the community for adopting our product at an early stage. For those that already have our (single-side) Forced Reset Selectors, you can use this Upgrade Kit to turn it into an ambidextrous safety.

It comes with virtually every part you need other than the trip lever and it won’t be here long. This product will only be offered for a limited time but we also have the full Ambidextrous FRS version for those that haven’t purchased the original single-side selector yet or those that just want the full ambi version straightaway.

This is the most robust solution on the market that enables the user to have 3 positions; SAFE, SEMI (Traditional) and FULL-SEMI. This Ambi Forced Reset Selector (FRS) is compatible with mil-spec AR15 (chambered in .223/5.56/.300 BLK) fire control groups and no modifications required. The Atrius AMBIDEXTROUS FORCED RESET SELECTOR isn’t just a safety, it’s an advantage.”

FEATURES:

• Ultra-Smooth Engagement – Crisp, tactile clicks with no mushy nonsense. Designed for 90-degree throw engagement.
• Runs with Mil-Spec Fire Control Groups – Seamlessly integrates with standard AR fire control groups, ensuring flawless function and longevity without modification.
• Positive Positioning Without Slippage – Engineered for rock-solid engagement, eliminating the risk of unintentional movement mid-fire, keeping you in full control at all times.
• 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.
• Aggressive Ergonomics – Textured, chamfered, and purpose-built for speed. Your thumb finds the selector instantly, even under stress, with no fumbling, no hesitation—just pure control.
• Drop-In Installation – Swap out your factory safety in minutes and experience the next level of firearm manipulation (some fitment may be required).
• MADE IN THE USA – Proudly manufactured by Americans for Americans.
