Area 419 Universal SA Magazine Extension Red — ARC & AICS 4/rd

Description

The Area 419 Universal SA Magazine Extension is a drop-in accessory designed to extend capacity for selected ARC and AICS-style magazines while maintaining proper cartridge alignment. Area 419 machines an angled attachment rail so the extension aligns with the magazine column rather than attaching as a simple rectangular block. The fluted sides provide a positive gripping surface for faster magazine manipulation without adding unnecessary weight. These extensions are not compatible with AI AW magazines and will not fit polymer AI magazines such as Magpul.
