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:
– 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
AR MAGLOCK products are 100% California legal and DOJ compliant, guaranteed.

Kingpin
Installation looked great appears as it came with the rifle no scratches or scuffs from installation very professional, highly recommend and will use again. It’s unfortunate that the service is even needed in idiotic gun control states however having the peace of mind knowing it’s done correctly and it won’t break it worth every penny. Extremely happy with WBT service
