FAB Defense Ultimag AR-15 Magazine 5.56/.223 5/rd Black

The FAB Defense Ultimag AR-15 Magazine 5.56/.223 5/rd Black is purpose-built for shooters who demand reliability in compact, limited-capacity configurations. Whether you're running a featureless rifle in a restricted state, training with low round-count drills, or setting up a precision rifle for controlled fire, this magazine delivers the same durability F.A.B. Defense is known for across law enforcement and military applications. The five-round capacity makes it ideal for hunters, competition shooters, and operators working within legal or tactical constraints that call for reduced-capacity feeding.

Engineered from impact-resistant polymer, the Ultimag maintains strict dimensional tolerances to ensure zero feeding malfunctions across mil-spec and commercial AR-15 platforms chambered in 5.56 NATO or .223 Remington. The reinforced feed lips and witness holes provide consistent spring tension and allow visual round count verification during tactical reloads. Measuring 4.8 x 1.65 x 9 inches and weighing just 0.34 pounds, this magazine is lightweight enough for extended carry without adding bulk, while the matte black finish resists glare and corrosion in field conditions.

Law enforcement, military, and civilian AR operators choose the FAB Defense Ultimag when capacity constraints are non-negotiable—whether due to jurisdiction, range protocol, or mission planning. It pairs seamlessly with any AR-15 lower receiver and upper assembly, requiring no modification or special adapters. Serious shooters typically stock multiple units to enable rapid magazine rotations during training or to maintain backup supplies for home defense scenarios where controlled fire discipline matters as much as firepower.
