Area 419 Firearms Plus 4 Magazine Extension Gunmetal Gray

The Area 419 Firearms Plus 4 Magazine Extension in Gunmetal Gray is a precision-machined magazine accessory that adds four rounds of capacity to compatible precision-rifle magazines. It is designed to fit the Area 419 ARC, standard AICS-pattern magazines, and Accurate Mag magazines, giving reloaders and precision shooters a straightforward capacity upgrade without swapping magazines at the bench or in the field.

Manufactured by Area 419, a precision machining company known for high-end rifle accessories and muzzle devices, the extension is finished in a durable Gunmetal Gray coating that matches the rest of the Area 419 product line. At 3.4 inches in overall length, it adds meaningful capacity while keeping a low, snag-free profile on the bottom of the host magazine. The extension replaces the factory base plate to add its extra four rounds of capacity.

Whether you run an Area 419 ARC, a common AICS short-action magazine, or an Accurate Mag, this Plus 4 extension delivers the extra rounds you need with the fit, finish, and machining quality Area 419 is known for.
