AR MAGLOCK Gen 4 + KINGPIN + KINGPIN PAL (New)

The KingPin PAL is an add-on lever system designed to work with AR Maglock Gen 2 or Gen 4 and a KingPin. It improves ergonomics and allows faster, more natural magazine changes making a fixed-mag rifle function closer to a standard mag release while staying compliant. It also helps with easier malfunction clearing and overall usability. 

AR Maglock Gen 2 / Gen 4 (with KingPin)

The AR Maglock system is a fixed magazine locking device that keeps your rifle compliant by preventing magazine release unless the action is slightly opened. When paired with the KingPin, it allows quick separation of the upper and lower receiver for faster reloads.

• Gen 2: Basic fixed-mag solution with a more fixed, less adjustable setup
• Gen 4: Updated version with improved adjustability to fit a wider range of receivers and allow finer tuning for function and compatibility

Simple way to think about it:

             Maglock + KingPin = compliance system

             PAL = performance upgrade (makes it faster & easier to use)
