Magpul ESK Enhanced Selector Kit for HK MP5/SP5/SP89/HK94 - Black Polymer

The Magpul ESK (Enhanced Selector Kit) transforms the ergonomics and usability of your HK MP5, SP5, SP89, or HK94 platform rifle. This ambidextrous selector upgrade replaces the stock safety lever with user-configurable components that let you operate the selector from your firing hand—eliminating the need to shift your grip or take your hand off the controls. Whether you're running Magpul's modular SL Grip Module or working with factory HK polymer trigger housings, the ESK drops in without gunsmithing and works with both three-position S-E-F and traditional Safe-Semi trigger packs.

Built from Magpul's proven high-strength polymer paired with corrosion-resistant steel internals, the ESK delivers the reliability you'd expect from the brand while adding genuine tactical advantage. The larger, easier-to-access lever geometry means faster transitions between safe and fire, and the ambidextrous design means lefties and righties alike get the same natural controls. If you're running a serious MP5 clone for home defense, competition, or range work, this is a straightforward upgrade that meaningfully improves weapon handling.

Installation is straightforward—no special tools required—and the modular design means you can configure the selector setup to match your preferences and shooting style. Drop it in, zero the controls, and get more out of your platform.
