It takes a lot longer to load a full 30-round AR-15 magazine than it does to send those rounds downrange. As such, anything that helps speed up loading time is a major benefit.
The Caldwell Mag Charger is designed to accept 50 loaded rounds directly from any common 50-round manufacturer box or aftermarket 50-round plastic storage box. Simply align bullet tips and dump ammo into the Mag Charger, ammo is automatically aligned without touching a single round.
Once filled with ammo, insert any AR magazine (mil-spec or polymer) into the Mag Charger just as you would into a rifle and run the plunger back and forth loading five rounds per stroke as the spring-loaded ammo carrier automatically aligns and advances the next five rounds until magazine is fully loaded. An Ammo Transfer Tray is included to invert ammo that is positioned in ammo boxes with the bullet tips oriented down or to stage bulk ammo for dumping into Mag Charger. MSRP for the Mag Charger is $89.99.
