Magpul

The Magpul ESK (Enhanced Selector Kit) - AR is a modular, ambidextrous selector kit designed for AR pattern firearms that provides user-configurable selectors with modern ergonomics at an accessible price. The ESK AR includes three levers: full, short, and hybrid, a selector pin, and a reversible, corrosion-resistant steel selector axle with 60 and 90-degree options. The selector pin comes in either black or red and secures the lever to the axle while acting as a selector position indicator. Installing the levers is easy and can be done without any tools. When its time to remove a lever, all thats required is a punch. With smart design and ergonomic angles in the right spots, this kit allows multiple selector variations and easier firing hand selector manipulation to allow a modern manual of arms to be employed. Designed for Mil-Spec AR-pattern lower receivers. Not compatible with select fire receivers. Made in the USA.
