Magpul ESK — SL Grip Selector Kit for HK MP5 — Ambidextrous Safety/Selector

Improved controls for a classic platform

The Magpul ESK (Enhanced Selector Kit) SL Grip selector is a modular solution designed for SL Grip modules and MP5-style trigger housings from Heckler & Koch. It replaces or upgrades the factory selector levers to provide better ergonomics and faster, more positive selector manipulation.

Magpul innovation and problem solving

Magpul’s ESK line addresses a common user complaint with the MP5 family: stiff or awkwardly shaped selector levers. The SL Grip selector offers redesigned lever profiles and geometry to reduce lever stiffness and make mode changes (Safe / Semi / Auto) quicker and more intuitive.

Modular, ambidextrous design

The ESK SL Grip selector is fully modular and supports ambidextrous operation. Multiple lever sizes and shapes are available within the system, allowing users to configure selector throw and purchase according to personal preference or mission requirements.

Customisable ergonomics

Choose the lever profile and length that best fits your hand and shooting style. The modular approach speeds activation and deactivation of the selector with either hand, improving transitions and overall handling in dynamic scenarios.

Durable modern materials

Components are manufactured from high-strength polymer with corrosion-resistant steel inserts where load-bearing strength is required. The result is a lightweight, rugged selector assembly built for long service life and reliable operation.

Compatibility note

This selector kit is intended for MP5-style trigger housings that use SEF (Safe / Semi / Full) markings or equivalent selector indexing. It is not compatible with all newer housings that use pictogram-style markings or different internal geometries. If your MP5 variant uses pictograms or non-standard trigger housings, please verify compatibility before purchase.
