AR MAGLOCK KingPin for Gen 2 & Gen 4 AR MAGLOCK systems on AR-15 .223 / 5.56 platforms. The KingPin allows for minimal separation (action disassembly) of the upper and lower receivers. The new KingPin holds the upper receiver from flying open when disassembling the action. Just a simple push on the pin with your thumb opens the action for mag changes, then automatically re-locks when you push the receivers together.
The KingPin benefits:
â€“ Keeping your critically important bolt catch
â€“ Seamless double feed clearing
â€“ Bolt hold back on last round
â€“ Fast magazine changes (as fast as OEM mag release button)
â€“ Clear access to your safety selector
â€“ Easy removal from the receiver to fully open the action
