The CMMG 57AFD1E 5.7x28mm extension is a magazine capacity upgrade designed for shooters running FN Gen1 Five-seveN magazines. If you've got an early-generation Five-seveN and want to carry or store more rounds without swapping mags, this extension adds 10 rounds to your existing magazine tube. It's a straightforward way to boost capacity on compatible Gen1 magazines—just slide it on and you're done.
The 5.7x28mm cartridge has carved out a niche for shooters who value compact, low-recoil performance with decent velocity and magazine capacity. Whether you're running the Five-seveN for sport shooting, duty applications, or general range work, magazine real estate matters. This CMMG extension lets you get more rounds downrange between reloads.
One thing to lock in: this extension is built specifically for FN Gen1 Five-seveN magazines. The newer generation magazines are not compatible, so verify what you're working with before ordering. If you're running original-generation Five-seveN mags, this is a proven way to add capacity without hunting down harder-to-find magazine options.
No. This CMMG extension is designed exclusively for FN Gen1 Five-seveN magazines. It is not compatible with the newest generation magazines, so check your magazine to confirm it's a Gen1 before ordering.
The extension adds 10 rounds to your existing FN Gen1 magazine tube.
