Atrius Development Group Ambidextrous Forced Reset Selector Mil Spec Ambi - SKU: ADG-FRS-AMBI-MS - UPC: 850079014091
Product Description
The Atrius Development Group Ambidextrous Forced Reset Selector (ADG-FRS-AMBI-MS) is an engineered safety selector mechanism designed specifically for AR-15 pattern lower receivers running forced reset triggers (FRT) and active mechanical reset trigger systems. Developed by Atrius Development Group, this selector provides dual-sided lever control while maintaining positive mode detent feedback and smooth rotation stroke.
Precision CNC-machined from high-strength steel alloy and treated with a corrosion-resistant black nitride/phosphate protective coating, the ADG-FRS-AMBI-MS incorporates custom cam geometry engineered to clear modified trigger tail profiles. Ambidextrous levers allow both right-handed and left-handed operators to manipulate fire control state quickly and intuitively under dynamic shooting conditions.
Built to fit standard mil-spec receiver safety selector journals, the assembly includes deep-cut textured selector levers, locking screws, detent spring interface grooves, and all necessary hardware for direct installation into custom AR-15 lower receiver builds.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits standard mil-spec AR-15 lower receivers utilizing forced reset or specialized mechanical reset triggers. (Ensure trigger tail geometry matches selector drum clearance prior to final staging).
- Verify host lower receiver is completely clear, magazine removed, and chamber visually and physically confirmed empty.
- Ensure the hammer is cocked back into the locked position before removing or installing safety selectors.
- Slide the main selector shaft into the lower receiver safety pin hole from the left side until seated.
- Install the right-side ambidextrous lever onto the selector drum keyway and apply threadlocker to the retaining screw before torquing down.
- Perform complete safety function checks (Safe, Semi, and Reset mechanical cycle checks) prior to live firing.
Key Features
- Ambidextrous Dual-Lever Control: Provides rapid, intuitive safety manipulation from either side of the lower receiver.
- Optimized Forced Reset Cam Geometry: Engineered specifically to interface cleanly with forced reset trigger tails without binding.
- Precision Steel Construction: CNC-machined alloy steel absorbs high cycle speeds and mechanical impact schedules.
- Durable Protective Finish: Black anti-corrosion coating resists carbon build-up, heat, and surface wear.
- Mil-Spec Journal Dimensions: Drops into standard AR-15 lower receiver safety selector mounting holes.
- Textured Grip Levers: Deep serrations ensure positive thumb purchase with wet hands or gloved operation.
