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:
Äâ‚¬â€œ Keeping your critically important bolt catch
Äâ‚¬â€œ Seamless double feed clearing
Äâ‚¬â€œ Bolt hold back on last round
Äâ‚¬â€œ Fast magazine changes (as fast as OEM mag release button)
Äâ‚¬â€œ Clear access to your safety selector
Äâ‚¬â€œ Easy removal from the receiver to fully open the action
