Why the Fortis REV II Is the Rail Serious Shooters Choose

• Ultra-Lightweight One-Piece Design: Machined from 6061-T6 aluminum for the ideal strength-to-weight ratio.

• M-LOK Mounting System: Attach accessories directly at the 3, 6, and 9 o’clock positions for true modular flexibility.

• Standard Barrel Nut Mounting: No proprietary tools needed — installs easily on most AR-15 platforms.

• Exceptional Rigidity: Keeps optics and attachments stable even under recoil and extended use.

• Type III Hardcoat Anodized Finish: Rugged protection against wear, corrosion, and harsh environments.

• Full-Length Picatinny Top Rail: Mount optics, iron sights, or tactical accessories with confidence.

• Clean, Aggressive Styling: Designed to complement the lines of modern rifles while reducing unnecessary weight.

Every Fortis REV II rail is a reflection of precision craftsmanship and attention to detail — delivering performance that rivals handguards twice its price.
