Area 419 Universal +4 Magazine Extension Black
Precision-engineered magazine extension adds 2-5 rounds to ARC and AICS magazines. Angled attachment rail ensures proper cartridge alignment. Fluted sides aid gripping and reduce weight.
Engineering Excellence in Magazine Extensions
Area 419 has engineered a magazine extension that sets the standard for the industry. While competitors offer simple rectangular blocks, Area 419 recognized a fundamental design flaw: most magazine extensions attach parallel to the magazine body, but magazine bottoms are angled. This misalignment compromises reliability when adding more than a couple of rounds.
The Difference: Precision Design
Area 419 solved this problem by cutting the attachment rail at an angle that matches your magazine's geometry. The result is a straight, unobstructed column of cartridges flowing directly into the extension. This precision work—performed in a single four-axis milling operation—delivers superior reliability and function.
