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 (Single) 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 

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.

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.
