Gauntlet Arms “Ace Series” AR-15 M-LOK Freefloat Handguard — 4", 7", 10", 15" (Black)

Personalize your AR-15 build with the Gauntlet Arms “Ace Series” M-LOK Freefloat Handguard — a slim, precision-machined rail that balances strength, weight savings, and modularity. CNC-machined from 6061-T6 aircraft-grade aluminum and finished with Type III hardcoat anodize, the Ace Series provides a continuous Picatinny top rail and M-LOK attachment slots for fast accessory mounting. Each handguard ships with a high-quality steel barrel nut and mounting hardware for secure, anti-rotation installation.

The Ace Series is available in four lengths to suit any build: compact PDW (4"), carbine/CQB (7"), extended carbine (10"), and long-range / full-length (15"). Designed to freefloat the barrel, the handguard helps improve accuracy, protect the shooter's hand from barrel heat, and provide ample real estate for sights, grips, lights, and other accessories. Verify your rifle’s gas system length before ordering to ensure full barrel coverage.
