The Area 419 419-Mag-Ext-Red Plus 4 Magazine Extension is engineered to add dependable capacity to ARC, AICS, and Accurate rifle magazines. Machined as a true extension rather than a simple block, its angled attachment rail keeps the cartridge column straight as rounds feed into the extension, supporting reliable function with higher round counts. The fluted sides provide a secure gripping surface and help trim unnecessary weight, while the red anodized finish offers easy visual identification in your gear.

This extension is ideal for precision rifle shooters who want a few extra rounds for matches, training days, or extended range sessions without changing their magazine system. Designed to work with a variety of short-action steel magazines, it delivers a clean install and consistent performance when properly matched to compatible mags. Area 419’s focus on careful machining and thoughtful design makes this Plus 4 extension a practical upgrade for shooters who value reliability and smart engineering.
