I bought this script like half a year ago.

It takes some time to setup but if you follow his instructions you should be good to go. Its not just you open the program and start shooting. You need to setup it yourself. It requires some actual recoil knowledge if you want to record an AK movement since you have to do it yourself. The other settings are pretty simple if you go to a aimtrain server and take some time to configure for yourself. No bans for me ever.
He has always answered every guestion i have without problems, even when i was stupid and didnt read his instructions carefully.
