Introducing the Area 419 Universal Mag Extensions the pinnacle of precision engineering in magazine extensions. Unlike other options on the market that are merely rectangular blocks, our extensions are meticulously crafted to maintain the integrity of your magazine's design. Recognizing that the bottom of your magazine is angled, we took the extra step to cut the attachment rail at an angle that aligns perfectly with the magazine pocket. This innovation ensures that the column of rounds feeds straight down into the extension, enhancing reliability beyond just +2-round. Crafted through a dedicated milling process using a 4th axis in one operation, we prioritized accuracy and performance to provide you with the most advanced mag extension available. The fluted sides not only add an aesthetic touch but also provide an excellent gripping surface for quick magazine changes while reducing overall weight. Initially designed for the American Rifle Company +4 mag extension, our versatility shines through as we've redesigned it to seamlessly fit a variety of magazines, including the ARC 10-round mag, AICS 5 or 10-round and Accurate Mag for both standard bolt face and SAUM/WSM configurations. Please note, these extensions are not compatible with AI AW magazines due to their fixed/welded floorplate. Elevate your shooting experience with the reliability and innovation of Area 419 Universal Mag Extensions.
