AR Maglock AR-15 (.223/5.56) Kingpin
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.
- 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
