The UTG Pro Slim Rail Free-Float Handguard in 15 inches, black anodized aluminum (brand part number MTU019SS), replaces the factory AR-15 handguard with a free-floating design built around a proprietary attachment system and a compact, slim profile. A continuous Picatinny rail runs the full length at the 12 o’clock position, while three user-detachable, 2-slot KeyMod rail sections cover the 3, 6, and 9 o’clock positions for accessory mounting only where it’s needed. An integral anti-rotation tab locks the handguard in place, and the design accommodates a low-profile gas block for a clean overall build. UTG Pro builds this handguard in the USA specifically for standard AR-15 gas tubes and standard, non-oversized upper receivers; compatibility with special piston systems or redesigned uppers is not guaranteed.
