Description From Manufacturer Website

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

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.
