5KU B-18 – Top Mounting Rail for AKS-74

The 5KU B-18 is a tactical top rail designed specifically for AKS-74 replicas and weapons. Inspired by the Zenitco design, this top mounting rail allows the installation of modern optics (red dots, scopes, tactical accessories) while maintaining the compact profile and distinctive aesthetics of the AK platform.

Made of CNC aluminum, this rail offers exceptional lightness, exceptional strength, and a perfectly stable mounting. Its flush design allows for open sights in the event of optic failure and does not interfere with the AKS-74's folding stock.
