An Extension Designed to Increase Capacity in Your Five-Seven Magazines

One of the benefits of the FN FiveSeven and its unique 5.7x28mm cartridge is increased capacity, and CMMG offers an opportunity for owners of this handgun to enhance magazine capacity even more. The CMMG FiveSeven Pistol Magazine Extension Kit adds an extra 10 rounds to the existing capacity of your FiveSeven handgun mag. However, this kit is not compatible with the newest magazines out from FN.
