The Atrius Forced Reset Selector (FRS) is revolutionizing the AR-15 experience, offering shooters a seamless blend of safety, speed, and precision. Compatible with mil-spec AR-15s chambered in .223, 5.56, or .300 BLK, this innovative three-position selector—SAFE, SEMI, and SUPER-SEMI—delivers unmatched control and performance. The Atrius FRS is a must-have for firearm enthusiasts.  This is the FIRST of its kind!

What is the Atrius Forced Reset Selector?

The Atrius FRS is a drop-in safety selector designed to enhance the AR-15’s firing capabilities without modifying the fire control group. Unlike forced reset triggers (FRTs), which can accelerate wear on internal components, the FRS offers a mechanically leveraged design that preserves your rifle’s longevity. Priced at $199, it’s a cost-effective alternative to pricier FRTs, providing a faster trigger reset for rapid, controlled shooting while remaining semi-automatic and legally compliant.

Key Features of the Atrius FRS

  • Ultra-Smooth Engagement: Enjoy crisp, tactile clicks with a 90-degree throw for precise mode switching.

  • Mil-Spec Compatibility: Works seamlessly with standard AR-15 fire control groups, including some aftermarket triggers like Rise Armament RA434 and Jacob Grey Signature Series.

  • Positive Positioning: Engineered to prevent slippage, ensuring reliable control under stress.

  • Hardcore Durability: Made from heat-treated 4140 steel with a corrosion-resistant finish, built to withstand harsh conditions.

  • Aggressive Ergonomics: Textured and chamfered for quick, instinctive operation.

  • Drop-In Installation: Swap out your factory selector in minutes, though some fitment may be required.

Why Choose the Atrius FRS?

The Atrius FRS stands out for its balance of performance and reliability. Unlike other super safeties that require extensive trigger modifications, the FRS is a selector-only solution, making it easier to install and tune. YouTube reviewers, such as VP Nation Tim and BattleHawk Armory, praise its ability to increase the rate of fire while maintaining accuracy, with one test achieving a 30-round mag dump in just 2.21 seconds. Its robust construction and compatibility with various ammo types (e.g., 55gr and 115gr) make it ideal for both recreational shooting and practical applications like pest control.

Real-World Applications

The FRS shines in scenarios requiring rapid, controlled fire:

  • Range Fun: Enthusiasts love the “giggle factor” of faster follow-up shots, as noted by Carolina EDC Reviews.

  • Pest Control: A customer cited by BattleHawk Armory used the FRS to manage hog clusters effectively, leveraging its enhanced rate of fire.

  • Tactical Use: The FRS’s reliability and ergonomics make it suitable for high-stress situations where quick mode transitions are critical.

Installation and Compatibility

Installing the Atrius FRS is straightforward but requires attention to detail:

  1. Remove the Grip: Unscrew the grip, carefully retaining the spring and detent.

  2. Remove Existing Selector: Push out the current selector, possibly loosening the trigger pin halfway.

  3. Install FRS: Slide the FRS’s smooth side in from the right, attach the J-arm, and screw in the paddle, ensuring it aligns with the hammer.

  4. Function Check: Test all three positions (SAFE, SEMI, SUPER-SEMI) to confirm proper operation.

Compatibility Requirements

  • Trigger: Must be mil-spec without a relief cut (solid back trigger shoe). Some aftermarket triggers, like the Rise Armament RA434, are compatible.

  • Lower Receiver: Requires an FA pocket or low shelf.

  • Bolt Carrier Group: Must be full-auto (FA) compatible.

  • Buffer Weight: H2 or H3 recommended for optimal cycling, especially with suppressors.

Tuning Tips

  • Ammo Selection: The FRS performs best with 55gr or 115gr ammo for 5.56 and 9mm setups, respectively. Heavier grains (e.g., 124gr) may cause bolt bounce in some configurations, as noted by VP Nation Tim.

  • Gas System: Adjust gas blocks for reliable cycling, especially with suppressors. Avoid over-tuning for specific ammo, as it may limit versatility.

  • Maintenance: Regularly check for wear on the lever to prevent breakage, particularly with high-cycle rates.
