Product Details

The Magpul ESK (Enhanced Selector Kit) offers a variety of selector levers for the Magpul SL Grip Module & HK Polymer Trigger Housings.

It provides a modern rendition of the classic MP5 SSL with updated aesthetics.

With easier access to the user-configurable levers, the Magpul ESK allows quick firing hand activation and deactivation of the safety and provides for ambidextrous use. Constructed of our high-strength polymer and corrosion-resistant steel, these components are built with the proven reliability Magpul is known for.
