What the B.A.D. BAD-ASS PRO Full Selector Is and Who It Is For
This is a full-auto-ready ambidextrous safety selector from Battle Arms Development, engineered for duty rifles, agency armories, and high-round-count training guns. The steel core is designed for consistent engagement across every selector position.
It suits professionals and enthusiasts who run demanding rifles and want a control that keeps up. Anyone building a rifle around a full-auto or burst fire control group will value the crisp, repeatable throws.

Specifications and Build
The B.A.D. BAD-ASS PRO Full selector centers on a steel core that is nitride treated for added corrosion resistance and long-term wear protection. That treatment helps the selector survive high-round-count sessions, duty carry, and rough field conditions.
The polymer levers keep weight down while still providing a solid, textured contact surface. Because the lever setup is modular, you can tailor the control geometry to your grip and mission profile.
The combination gives you the durability of steel where it matters and the light, adjustable feel of polymer where you touch it.
Practical Use, Care, and Compatibility
Installation mirrors a standard ambidextrous selector swap, and the crisp detents make each position easy to confirm by feel. Set your preferred lever configuration, seat the detent and spring, and the control is ready for work.
Maintenance is minimal thanks to the nitride finish, which sheds fouling and resists rust. A wipe down during normal cleaning keeps it running smoothly for the long haul.

Duty-Grade Reliability
Full-auto and burst receivers put more demand on a selector than a semi-auto gun ever will. This unit is engineered for that stress with a hardened steel core that keeps engagement crisp under heavy use.
The modular levers let an armorer standardize control layouts across a rack of rifles. That kind of consistency matters in a training pipeline or a duty environment where every gun should feel the same.
Nitride treatment keeps corrosion at bay in humid armories and rough field conditions alike. It is the sort of part you install once and stop thinking about, which is exactly what a professional wants.
Getting the Most From It
During installation, set your lever configuration first, then seat the detent and spring for a clean, positive feel. Confirm each position before the rifle goes hot.
Because the core is steel and nitride treated, it thrives on high round counts and rough handling. Routine cleaning is all it needs to stay reliable.
This selector ships direct where state and local law allows, arriving ready for your fire control group.
It pairs well with an enhanced trigger and ambidextrous bolt catch for a fully outfitted professional rifle.
Set it up once to your preference, and it delivers the same crisp actuation session after session.
When your rifle has to run no matter what, the B.A.D. BAD-ASS PRO Full selector answers the call. Ships direct to your door, no FFL required.
