FAB Defense Ultimag 10R — 10-Round — 5.56×45mm NATO — AR-15 / M16 / M4 — Flat Dark Earth — Polymer & Steel Body — FXUMAGR10T (UPC: 7290105947338)

Optimize your AR-platform for compliance, balance, and reliable feeding with the FAB Defense Ultimag 10R — a premium 10-round magazine engineered specifically for 5.56×45mm NATO cartridges and mil-spec AR-15/M16/M4 platforms. The FXUMAGR10T blends a lightweight polymer body with a durable steel feed/locking lip assembly, delivering dependable performance, fast reloads, and an attractive Flat Dark Earth (FDE) finish that complements modern builds.

Engineered for Reliability and Legal Compliance

Whether you need a compact, low-capacity magazine for local regulations, range use, or precision shooting, the Ultimag 10R is purpose-built to deliver consistent, trouble-free operation. FAB Defense designed this mag to match the geometry and feeding angles of standard AR bolts and feed ramps so you get smooth insertion, reliable lockup, and positive feeding from the first round to the last.

Hybrid Construction — Best of Both Worlds

The Ultimag 10R’s polymer outer body keeps the weight down and resists dents and corrosion, while the steel feed lips and locking interface provide rock-solid engagement with the magwell and bolt carrier group. This hybrid approach offers:

• Impact and chemical resistance from high-grade polymer (body),

• Precise, wear-resistant feeding geometry from hardened steel feed lips, and

• Reduced weight compared to all-steel options for better balance and handling.

Compact Size, Full-Feature Performance

At 10 rounds, the Ultimag 10R reduces bulk and pocketing issues while preserving the AR’s balance and handling. Key practical advantages include:

• Shorter overall length for compact carry and streamlined controls,

• Easy indexing during reloads thanks to a tapered follower and smooth polymer exterior, and

• Strong magazine spring and follower to ensure positive feeding under rapid or sustained fire.

Proven Feeding Design

FAB Defense built the Ultimag series around proven feed geometry: an anti-tilt follower, optimized internal cavity shape, and a spring tuned to feed a variety of 5.56 loads — from lightweight training bullets to heavier match projectiles. The steel feed lips maintain consistent alignment with your upper’s feed ramp, minimizing misfeeds and increasing confidence on the line.

Flat Dark Earth Aesthetics

The FXUMAGR10T comes in an attractive Flat Dark Earth finish that matches modern FDE furniture and accessories. The neutral tone is ideal for tactical builds, hunting rigs, or simply giving your rifle a refined, coordinated look.

Benefits & Why Choose the Ultimag 10R

Use Cases

• Range training & practice where lower capacity mags reduce reload penalties and improve fundamentals.

• Compliance builds in areas with magazine capacity restrictions.

• Hunting or stalking rigs where compact size and lower profile are desired.

• Collecting & display — matches FDE parts for a coordinated aesthetic.

Care, Maintenance & Best Practices

• Inspect feed lips and body regularly for cracks, deformation, or corrosion.

• Keep the spring and follower clean; a light application of firearm lubricant on the spring can reduce friction and extend service life.

• Store magazines loaded only when intended for long-term storage; rotating loaded mags helps preserve spring life.

• Verify fit and function with your specific rifle and ammunition before duty or range use.

Compatibility Note

Designed for standard mil-spec AR-15/M16/M4 lower receivers. While the Ultimag 10R is compatible with most AR pattern rifles, always verify fit and function in your specific firearm—especially if your lower or magwell is aftermarket or non-standard.
