Area 419 Universal Magazine Extension Features The Area 419 Universal Magazine Extension is machined with an angled attachment rail that matches the angle of the magazine body itself so the column of cartridges travels straight down into the extension rather than being forced off axis. This angled cut was milled in a single operation on a 4th axis machine a more time consuming process Area 419 chose specifically because it delivers reliable feeding beyond the simple plus two capacity that competitors rectangular extensions are limited to. The fluted sides reduce weight while giving shooters a confident gripping point during fast magazine changes. Built from anodized aluminum in red the extension adds a distinct visual identifier for quick magazine recognition. Designed to work across a range of short action magazines the extension fits ARC 10-round magazines for a plus four or plus five increase depending on cartridge and AICS and Accurate Mag magazines in 5 or 10 round configurations for a plus two to plus four increase. It is not compatible with AI AW magazines due to their fixed welded floorplate nor with Magpul or other polymer AI magazines. Installation is straightforward requiring no gunsmithing or special tools to attach. For shooters looking to extend capacity on a short action precision rifle without sacrificing reliable feeding this Area 419 extension is available for sale at GrabAGun.
