The Area 419 Plus 4 Magazine Extension Black (419-MAG-EXT-BLACK) is a precision-machined upgrade for ARC, AICS, and Accurate Mag short-action magazines. Cut with an angled attachment rail that matches the natural angle of the magazine body, it allows the column of cartridges to feed straight into the extension for smooth, reliable operation. Deep fluting along the sides offers a secure gripping surface during fast magazine changes while trimming unnecessary weight, and the matte black finish blends cleanly with most precision rifle setups.

This extension is ideal for precision rifle shooters who need a modest capacity boost without compromising feeding reliability. Whether you are running drills at the range, shooting local matches, or training for long-distance engagements, the added rounds and improved handling help keep you focused on your shooting instead of your gear. Area 419’s careful machining and thoughtful design choices reflect the brand’s reputation for innovation and attention to detail in modern rifle accessories.
