ATRIUS DEVELOPMENT GROUP ADG-FRS-S FORCED RESET SELECTOR

The Atrius Development Group Forced Reset Selector (ADG-FRS-S) is a drop-in AR-15 safety selector upgrade chambered for .223, 5.56, and .300 BLK that gives competitive shooters, tactical enthusiasts, and serious AR builders three distinct selector positions in a single hard-use component. This forced reset selector for AR-15 platforms delivers faster trigger reset and enhanced fire control without the wear and complexity of forced-reset trigger systems.

Key Features

• Part number: ADG-FRS-S
• Compatible calibers: .223 Rem, 5.56 NATO, .300 BLK
• Platform compatibility: Mil-spec AR-15 with full-profile trigger pocket lower receiver and full-profile BCG
• Selector positions: SAFE, SEMI, FULL-SEMI (three-position configuration)
• Throw angle: 90 degrees
• Material: Heat-treated 4140 steel
• Finish: Corrosion-resistant black coating
• Installation: Drop-in, single-side selector
• Ergonomics: Textured, chamfered lever with aggressive grip geometry
• Country of origin: USA
• Weight: 0.2 oz
• Selector screw: T10, 4/40 thread torqued to 15 in/lbs with blue Loctite

Special Features

• The FULL-SEMI position uses a mechanically leveraged cam design to force the trigger to reset faster after each shot, enabling quicker follow-up fire compared to a standard two-position selector
• Unlike forced-reset trigger systems that accelerate wear on internal components, the ADG-FRS-S operates through the selector rather than altering the trigger group itself, preserving fire control group longevity
• The 90-degree throw produces crisp, tactile detent clicks at each position, eliminating mushy engagement and providing a clear mechanical signal when the selector moves between SAFE, SEMI, and FULL-SEMI
• The textured, chamfered lever provides a positive grip surface for fast, deliberate selector manipulation under any conditions
• Constructed from heat-treated 4140 steel with a corrosion-resistant finish, the ADG-FRS-S holds up to mud, rain, and heavy field use without surface degradation
• Manufactured in the USA and designed to run directly with mil-spec fire control groups, requiring no trigger group modifications for most standard AR-15 lower receivers

Practical Benefits

• The drop-in design means you can swap your factory safety selector in minutes using minimal tools, making this a practical upgrade for existing builds without a full trigger job
• The FULL-SEMI position gives you faster engagement and follow-up shot capability on the range or in competitive shooting scenarios where trigger speed matters
• Works with mil-spec AR-15 platforms chambered in .223, 5.56, and .300 BLK, making it compatible with the most common AR builds in use today
• The three-position layout keeps traditional SEMI and SAFE modes fully intact, so you retain all standard functionality while adding the forced reset option when you need it
• Ideal for high-volume range sessions, practical shooting competitions, and tactical training builds where your AR needs to perform under sustained use
• Your AR-15 build gains a genuine mechanical upgrade that increases speed without sacrificing the durability or reliability you depend on

The Atrius Development Group Forced Reset Selector (ADG-FRS-S), chambered for .223, 5.56, and .300 BLK, is a proven platform upgrade and smart addition for the serious AR builder or competitive shooter who demands faster reset and lasting durability from every component on their rifle.
