The latest in speed-loading technology, the M12 Sidewinder is very easy to use and super fast at loading your M4 mid cap magazines. To operate the speed loader, simply fill the reservoir with BBs, attach your mag, then wind the handle. Each rotation of the handle loads 12 BBs into the mag. For most mags, this means you need to turn the handle about 12 times for a complete fill. This loader is super easy to use and will drastically cut down the amount of time you spend loading your mid caps.
Comes with a 1-year manufacturer's warranty.
