Magpul HK Roller Lock Firearms ESK

The Magpul ESK (Enhanced Selector Kit) offers a variety of selector levers for the Magpul SL Grip Module & HK Polymer Trigger Housings. Keeping with the Magpul blueprint of innovation, the Magpul ESK results in a modular, ambidextrous selector with enhanced ergonomics. 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.

The Magpul ESK is compatible with SEF/SAFE-SEMI trigger packs and is NOT compatible with Ambi/Navy/FBI or CETME trigger packs. If your firearm is equipped with an Ambi/Navy/FBI trigger pack it must be exchanged for a SEF/SAFE-SEMI trigger pack in order to function with the Magpul ESK.
