Area 419 Firearms Plus 4 Universal SA Magazine Extension - Red

The Area 419 Firearms Plus 4 is a universal short-action magazine extension that adds four rounds of capacity to compatible bolt-action rifle magazines. Precision machined from aluminum and finished in a durable red anodized coating, this extension clamps onto the existing magazine body to extend the column without altering feed geometry.

Engineered as a true universal fit, the Plus 4 installs on Area 419 ARC 10-round magazines, AICS-pattern 5- and 10-round magazines, and Accurate Mag standard and AW magazines chambered in short-action calibers. It gives precision rifle competitors and hunters a clean +4 capacity upgrade without swapping magazines between stages or hunting positions.

Whether you run an ARC magazine in a competition rig or a standard AICS short-action magazine on a hunting build, the Area 419 Plus 4 delivers the extra short-action capacity in a low-profile, factory-direct package.
