Magpul Industries ESK Safety Selector AR-Platform Ambi 60/90 Black

The Magpul ESK (Enhanced Selector Kit) is a modular, ambidextrous safety selector built specifically for AR-platform rifles. At its core is a chromoly steel selector drum with a corrosion-resistant Nitride finish, delivering smooth, positive engagement whether you prefer a standard 60-degree throw or a more relaxed 90-degree throw. The reversible steel selector axle lets you swap between the two throw options without any permanent modification.

The kit ships with three interchangeable polymer levers (full, short, and hybrid) so you can dial in the reach and lever feel that best matches your shooting style and hand size. Installation is drop-in and the included selector pin secures everything to a standard AR lower. All components are engineered by Magpul Industries to tight tolerances for years of hard service.
