Area 419 Firearms Plus 4 Universal SA Magazine Extension - Raw

The Area 419 Plus 4 Magazine Extension is a precision-machined short action magazine extension engineered to add four additional rounds of capacity to compatible rifle magazines. Built for precision rifle competitors and recreational shooters who want extra firepower for long-range stages or extended range sessions, this extension fits the popular AICS-pattern short action magazine platform commonly used in bolt-action and chassis-system rifles.

Machined from durable 6061-T6 aluminum and finished in a raw (uncoated) appearance, this extension offers lightweight construction with the rigidity needed for repeated magazine insertions and removals. The raw finish delivers a clean, industrial look that suits shooters who prefer a minimalist appearance or plan to apply their own custom coating. Area 419 manufactures these extensions in the USA using advanced CNC machining processes.

Designed as a universal short action (SA) solution, the Plus 4 extension is compatible with a variety of short action magazines including the ARC 10-round, AICS 5 and 10-round, and Accurate Mag patterns in standard bolt magazine configurations. Installation is straightforward, letting shooters quickly upgrade their magazine capacity without major modification.
