Magpul ESK Ambidextrous Safety Selector Kit – Black

The Magpul ESK (Enhanced Selector Kit) is a modular, ambidextrous selector kit engineered for Mil-Spec AR-pattern lower receivers. It provides user-configurable levers with modern ergonomics and selectable throw options. The kit includes three levers — full, short, and hybrid — a selector pin, and a reversible, corrosion-resistant steel selector axle with 60° and 90° options. Levers install without tools and require only a punch for removal; the kit is designed for semi-automatic AR-platform rifles and is not compatible with select-fire receivers.
