Area 419 Firearms +4 Magazine Extension - Blue

The Area 419 Firearms +4 Magazine Extension in Blue adds four rounds of capacity to a wide range of popular precision-rifle magazines. Machined by Area 419, this universal extension is engineered to fit AICS-pattern 5- and 10-round short-action magazines, the ARC 10-round magazine, and Accurate Mag magazines in standard bolt-action feed configurations. The extension allows the column of ammunition to travel straight down into the body, maintaining reliable feeding while giving shooters extra rounds for hunting, competition, or field use. Finished in a distinctive blue finish, the +4 extension installs easily on the host magazine, increasing total capacity by four rounds over the base magazine.
