Super easy install and fit snug on my zpap m70 - Texas Weapon Systems Yugo AK Gen-3 Dog Leg Scope Rail Top Cover

I got it in and was able to install it in under 20 minutes and i was moving sloooow. Awesome upgrade if you're looking for something besides a gas tube mount or a side rail. I was worried about movement at the hinge but there is absolutely zero movement when its closed. I've put about 100 rnds on it today to zero the optic (25 yrds) and check for POI shifts when opening and closing the cover but with 3 points of contact, everything seems solid. Won't know for sure until its put under a bit of stress and with a few more rounds from further distance but for now it gets a 5/5 from me. Plus i got free 2 day shipping from OP so that's always a plus.
