AR MAGLOCK KingPin .308 for Gen 4 AR MAGLOCK systems on AR-10 / .308 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 Retain 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
