MCK Micro Conversion Kits

Expand Your Platform with Micro Conversion Kit Accessories
Micro Conversion Kits, also known as MCKs, are compatible with a wide range of firearms, including Smith & Wesson, Glock, Taurus, Springfield Armory, and Sig Sauer handguns, allowing you to simply drop the pistol in and transform it into a much more expandable platform with superior handling. In addition to offering stability, much like a sporting rifle, Micro Conversion Kits and Micro Roni Conversion Kits offer the value of greater expandability. They offer extra rail space and mounting points for a wide range of Micro Conversion Kit accessories that can vastly improve your shooting experience.

This is our full collection of top MCK and CAA (Command Arms) Accessories, including:

● Thumb rests
● Polymer grips
● Slings & sling mounts
● Laser sights
● Additional Picatinny rails
● MCK glass breakers
● Weapon lights
● Red dot sights & optics
● And more

Compatible with a wide range of platforms including but not limited to Glock 17 and S&W M&P pistols, these accessories can improve stability, improve accuracy and shrink groups, enhance handling, provide extra visibility and boost your confidence. Check out our Top MCK Accessories blog for recommendations!
