Load your AR magazines in seconds with the Caldwell® Mag Charger™ Tac 30. Designed to accept 20 rounds of .223, 5.56 or .204 from any common 20-round ammo manufacturer box, three 10-round stripper clips or using the included stripper rail. Simply align bullet tips and dump ammo into the Mag Charger, which is automatically arranged without touching a round. Once filled, insert any AR magazine into the Mag Charger as you would into a rifle. Stroke the plunger back and forth, loading 10 rounds per stroke as the spring-loaded ammo carrier advances to the next 10 rounds until the magazine is fully loaded. The entire process of filling the Mag Charger and loading all 20 rounds into a magazine takes less than 10 seconds. Durable polycarbonate construction for long-lasting performance. Compatible with all AR-platform magazines, both mil-spec and molded plastic. Accepts 30 rounds of .223, 5.56 or .204.
