M-16/AR-15 Magazine Connector
Now you can increase your fire power 100% with Choate's Magazine Magazine Connectors. Constructed of two steel plates on front and back and a plastic filler blocks in the center. This superior design has several advantages. Both magazines point upward. This enables the shooter to use a bipod in a prone position without damaging the feed lips or getting dirt in the magazine. To load the second clip, just move the first magazine over 1" and reinsert.
