Battle Arms Development BAD-ASS-PRO Full Auto Ambidextrous Safety Selector 90 Deg Black Phosphate 8620 Steel - AR-15/M16/M4

Upgrade your AR-platform rifle with the Battle Arms Development BAD-ASS-PRO Full Auto ambidextrous safety selector, a professional-grade, duty-rated selector built specifically for AR-15, M16, and M4 lower receivers. This Full Auto variant uses the standard 90-degree throw configuration and is purpose-built as a direct replacement or upgrade for Mil-Spec-pattern lower receivers, including select-fire and machine-gun-pattern lowers that require the longer throw.

At the heart of the selector is a Swiss CNC-machined bar-stock steel core that has been through-hardened for long-term durability under hard use. The ambidextrous levers are investment-cast 8620 steel finished in a corrosion-resistant Black Phosphate coating, with an ergonomic profile shaped for positive purchase with or without gloves. The levers attach to the core via a dovetail interface engineered for a tight, no-slop fit that holds up to repeated manipulation.

Fully ambidextrous, the BAD-ASS-PRO allows safe and fire control from either side of the rifle, and is 100% compatible with all known Mil-Spec AR variant lower receivers and aftermarket triggers designed for Mil-Spec-pattern AR-15 lowers. Designed and made in the USA by Battle Arms Development, the BAD-ASS-PRO Full Auto is a clean drop-in upgrade for any AR-platform build that demands confident, repeatable selector control.
