Like it's counterparts, this hopper-fed, loose-ammo loader eliminates hand fatigue and reduces magazine loading time and effort by more than 50 percent. Simply load your ammo in the 50-round capacity hopper and let the MagPump do the rest. The machined aluminum components self-sort ammunition in either direction. While the aluminum handle increases the loader efficiency and enhance its operation, loading 30 rounds in less than 30 seconds.
