The Fab Defense AR-15 Magazine 10/Rd Black Polymer, also known as the Ultimag 10R, is a compact, purpose-built magazine for AR-15, M4, and M16 rifles chambered in .223 Remington and 5.56 NATO. Its reinforced polymer body and steel components create a durable, lightweight design with a distinctive multi-textured exterior that promotes a secure grip and confident handling during reloads.

This 10-round magazine is ideal for shooters who need a lower-profile option for bench work, hunting in capacity-restricted areas, or focused training sessions at the range. The unique floor plate supports versatile coupling options, while the optimized internal geometry, low-friction follower, and corrosion-resistant spring are engineered for smooth, reliable feeding over extended use. Backed by Fab Defense’s reputation for thoughtful engineering and dependable accessories, the Ultimag 10R is a practical upgrade for any AR-15 platform.
