It wasn't as bad as others claimed it to be. Full metal construction, very sturdy top rail and the sights not not have bad. It fits on my WE and GHK. Although for the WE it needed a bit of filing down. Fast shipping as usual. Always follow my shipping notes. I totally will buy again from here.

[MadDog] Aluminium CNC AK Dust Cover W/ Tactical Rail & Rear Sight[BLK]

The rails are Polymer Not the Cover itself.
Like i said ONLY the rails. I thought the comeplete Cover with rails are aluminium.
Thats why it is a shame....

A shame that the rails are plastic (Polymer). I have a feeling that is more the AKM style AK out there because it didnt fit well on my GHK AK 74. In order to fit , the last rail in the direction to the trunnion sight post , you need to cut it off. After that that you put it on.

Quality is good enough but is more AEG style like. Didnt looked as good as i thought it would be on my GBBr.
