For existing MCK owners that own a one-point sling, a push-button sling swivel, and thumb rests

The TAC will feature the TAC compartment as well as a special rear housing that has been designed with additional storage in mind. The MCKTAC adds storage for an additional CR123 battery for your MCK Flashlight or optic, four 9mm rounds, OR even hearing protection!

The combination of the shooter’s arm at full extension and the resistance from the bungee style sling creates a steady platform for added accuracy and control when shooting the MCK TAC.

Installation of the upgrade kit is a simple user-friendly process that anyone can do in just seconds.

Fits ALL MCKs past, present, and future!
