FAB Defense Ultimag 2nd Gen Features The FAB Defense Ultimag 2nd Gen was developed over a full year of testing and feedback from military and police users operating in extreme and challenging field conditions. That testing led to a new reinforced and robust body design intended to withstand harder use than earlier generations of the Ultimag line. A multi textured surface improves grip during handling and magazine changes particularly useful when hands are wet gloved or under stress. The magazine holds 30 rounds of 5.56x45mm NATO or .223 Remington matching the most common AR platform chambering in service and sport use today. Internally a long lasting cataphoresis coated spring provides reliable corrosion protection and is designed to maintain its tension even during extended loaded storage a common concern for duty and standby magazines. A low friction follower works alongside that spring to improve feeding reliability across a wide range of ammunition types. The follower itself is high visibility allowing shooters to quickly identify an empty magazine at a glance rather than relying on weight alone. Finished in black polymer with a dedicated identification area for marking individual magazines the Ultimag 2nd Gen is built for shooters who demand consistent performance from their AR platform magazines.
