The MCK TAC micro conversion kit from CAA is compatible with more than 120 handguns in 17 different MCK chassis and is available in a wide variety colors and patterns. It ships with a special bungee sling, sling swivel and a pair of thumb rests for added stability. The combination of the shooter’s arm at full extension and the resistance from the bungee-style sling create a steady platform for added accuracy and control when shooting the MCK TAC. CAA811 installation of the upgrade kit is a simple user-friendly process and a TAC rear compartment provides storage for an additional CR123 battery for a weapon light or optic, up to four 9mm rounds or even hearing protection. MSRP: From $249. Contact: www.caagearup.com
