LCT Airsoft are really pushing hard in the development of rail systems for AK AEGs and GBBs. Their latest design is an upper rail system that can fit the LCT AK AEGs and GHK AK Gas Blowbacks. The design is actually simple as they added a flattop rail on the cover of the AK and if you combine this with the LCT TX Railed Hanguards can produce you AK rifles that have almost front to rear rails to rival AR platforms.
