In the modernizing world, the proprietary AK side optic rail is not the way to go to as you would have to mount a separate piece to mount your optic onto the gun, making it more bulky and heavy.
The Asura Dynamics AK Top Rail Dust Cover is a solid piece of full Picatinny rail made from lightweight aluminium that replaces your original dust cover. Fits AEG and GBB platform AKs. Note AKS74U and Micro aks might not be able to mount this item properly due to the front mounting point replacing the rear sight.
We do not suggest using this item on any real firearms for safety reasons.
