Don’t lose precious seconds in competition or combat fumbling for a spare magazine during a reload. This rugged speed loading system clamps directly to the lower receiver of any AR-15/M16 rifle or carbine and securely holds a second, fully loaded magazine alongside the mag well for super-fast mag changes. More reliable and easier to use than improvised methods, like taping two magazines together, that can cause malfunctions at critical moments. Closed-top design protects the spare mag from rain, dirt, dust, and debris and prevents the top round from jumping forward under recoil. Independent release system lets you drop the spare mag and the mag in the weapon separately to allow tactical reloads and greater flexibility in clearing malfunctions. Bolt Catch Extension (BCE) mounts directly to the factory bolt catch and lets you release the bolt, with or without the Redi-Mag attached to the gun, simply by slapping the BCE with an open palm. Installation requires no permanent alterations to receiver or mag well. Designed for mil-spec receivers; may not fit custom billet receivers. Machined Aluminum model offers lighter weight and a hinged mounting bracket for easier attachment to your rifle; does not have BCE.
