FAB Defense Ultimag 10R 5.56x45mm NATO 10Rd AR-15/M4/M16 Black Polymer Magazine

The FAB Defense Ultimag 10R is a lightweight, durable 10-round detachable magazine chambered in 5.56x45mm NATO (also accepts .223 Remington), built specifically for AR-15, M4, and M16 pattern rifles. The Ultimag pairs a polymer body with steel internal components for reliable feeding at a reduced weight compared to all-metal magazines.

The Ultimag 10R features an ergonomic external profile with molded grip texture, designed to make seating the magazine and performing reloads easier under pressure. The black polymer body is impact resistant and weather-tolerant, and the magazine weighs approximately 131 grams (0.289 lb). Its compact 10-round configuration also makes it a practical choice for use in jurisdictions with standard-capacity magazine restrictions.

Designed for 5.56x45mm NATO and .223 Remington AR-platform rifles, the Ultimag 10R is a solid option for range use, training, or as a reliable lightweight spare magazine for any AR-platform build.
