The AR MAGLOCK KingPin is designed for Gen 2 and Gen 4 AR MAGLOCK systems on AR-15 .223/5.56 platforms, allowing for fast and compliant magazine changes with minimal action disassembly. With a simple thumb push, the KingPin AR MAGLOCK opens the action for mag swaps and automatically re-locks when the receivers are closed, keeping the upper secure and preventing it from flying open. Built for reliability and ease of use, the AR MAGLOCK KingPin Gen 4 delivers seamless function and enhanced control, making it the ultimate upgrade for AR-15 shooters in regulated states.
The KingPin benefits:
Keeping your critically important bolt catch
Seamless double feed clearing
Bolt hold back on last round
Fast magazine changes (as fast as OEM mag release button)
Clear access to your safety selector
Easy removal from the receiver to fully open the action
