The Atrius Development Group Forced Reset Selector (FRS) is the most robust three-position safety selector on the market, purpose-built for mil-spec AR-15 platforms chambered in .223/5.56 and .300 BLK. Offering SAFE, SEMI (Traditional), and FULL-SEMI positions, this single-side selector delivers a forced-reset style function without requiring any internal trigger group modification on compatible lowers. Machined from heat-treated 4140 steel and finished with a corrosion-resistant coating, the ADG FRS is engineered for operators who demand absolute reliability and control. With a 90-degree throw, crisp tactile clicks, and aggressively textured ergonomics, this selector installs in minutes and transforms the way you interact with your rifle. Proudly made in the USA.
Product Highlights
- Drop-In Installation: Swaps out your factory safety in minutes with no internal modifications required for compatible mil-spec lowers (some fitment may be required).
- 3-Position Control: Provides SAFE, SEMI (Traditional), and FULL-SEMI positions, seamlessly integrating with standard mil-spec AR-15 fire control groups for .223/5.56/.300 BLK.
- Hardcore Durability: Crafted from heat-treated 4140 steel with a corrosion-resistant finish, built to withstand rain, mud, and heavy use without degrading performance.
- Mechanically Leveraged Design: Reduces wear on your rifle's internal components, preserving weapon longevity unlike forced-reset trigger (FRT) systems that accelerate internal degradation.
