"Despite the other reviews on this product I have absolutely no issues with it. It was solid with the provided screws and I could shake it about (rather violently) without any wobble. The issue with not being able to look down the sights to see the front was also not an issue (though I had to raise it up a bit more to see properly.) It is rather high up and would suggest a low sitting sight with it

"Great rail, came with all hardware needed, only issue is that the rail itself is slightly too skinny for my red dot sight to fully tighten. I ended up having to use a riser, so it kinda defeats the low-profile-ness of the rail. I'm sure other optics will work, just something to keep in mind.

"This rail replaces the rear iron-sight of an airsoft AK. The screw it comes with is too short for it to reach to the other side of the AK and screw on with the nut (provided). Make sure you have screws & extra nuts hanging around so you can put it on your AK correctly. Other than that, the rail fits well but it has a little bit of wobble (even tightened), I recommend hot glue to fix that.
