Capacity and size:
The M12 Sidewinder is a high-capacity speed loader that can hold up to 1600 BBs. It is also compact and lightweight, making it easy to carry in a standard double-stack M4/M16 magazine pouch.
Loading speed and features:
Each rotation of the crank loads 12 BBs, allowing you to fully load a mid-cap magazine in under 5 seconds. The speed loader also has an integrated winding clutch to prevent overfilling, a dot matrix for easy identification, and a pre-installed sound-dampening buffer.
The M12 Sidewinder is compatible with almost any M4 mid-cap magazine, but it requires a clutch adjustment when used with PTS EPM-1 magazines. See the instructions below for more information.
Note: If you do not adjust the clutch, the gears may break, and this will not be covered under warranty.
