The Area 419 419-MAG-EXT-BLUE Plus 4 Magazine Extension is a precision-machined upgrade for ARC, AICS, and Accurate magazines, designed to boost capacity while maintaining smooth, reliable feeding. Its angled attachment rail matches the natural angle of the magazine body so the column of cartridges continues straight into the extension instead of binding, and the fluted exterior cuts weight while adding a secure gripping surface for confident reloads.

This blue anodized extension is ideal for precision rifle shooters who want extra rounds for matches, training days, or extended range sessions without changing their magazine system. Compatible with many ARC, AICS, and Accurate standard bolt-face and SAUM/WSM magazines, it offers a practical capacity increase in a compact footprint. Area 419 is known for thoughtful engineering and meticulous machining, and this extension reflects that focus on function-first innovation.
