Quality is good. No problems installing.
Only problem I had was asking questions about the MI AK Mount I had purchased but, this part (lever) broke off. I contacted MI but, DID NOT receive reply. Nothing. Just totally ignored my request. I was asking is this broken lever under warranty. I'll never know because they refused to answer my request.
Instead of going back and forth and wasting my time requesting again, only to be ignored, I simply ordered this part.
So, if you're buying from MI, be aware that when it comes to a warranty, they will not answer you.
