***Estimated to Ship at the End of September 2025***
The most robust solution on the market that enables the user to have 3 positions; SAFE, SEMI (Traditional) and FULL-SEMI. This 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 FORCED RESET SELECTOR isn’t just a safety, it’s an advantage.
 
HOW TO ENSURE RELIABLE OPERATION:
This product was designed for mil-spec triggers that do not have a relief cut (that means the rear of the bottom half of the trigger - not the hammer, must be completely squared off. No u-notch.)
Your AR-15 lower receiver must have an FA Pocket OR Low Shelf
You must use an FA bolt carrier group
It is strongly recommended to only use an H2 or H3 buffer weight 
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.

Upgrade your firepower. Own your control. Rule the game.
 
COMPATIBILITY NOTICE:
Certain platforms, such as AR9 variants, may require professional gunsmithing to ensure proper function of the selector lever.
Firearms modified to "Super Safety" specifications may not be compatible with components designed for our FRS system, as the Atrius Safety Device features a solid lever cam design.
The Super Safety system incorporates a 15-degree tolerance due to its dovetail construction, which may allow for limited over-travel before the cam surface disengages from the trigger bar.
Selector Screw and Torque Spec: T10 screw, 4/40 thread, McMaster-Carr spring (9657K619). We recommend 15 in/lbs with blue loctite only. 
 
Please Note: This Atrius FRS will not work with AR-10(LR308)/SR-25 platforms without significant gunsmithing. In the near future we will be coming out with a model specifically catered to these platforms. 
Important: All modifications should be performed by a qualified gunsmith. Improper installation or unauthorized modification may result in malfunction or unsafe operation. Use and modify at your own risk. The manufacturer assumes no liability for damages or injuries resulting from incorrect installation or use outside of intended specifications.
