Seems tight. Have not noticed any slack.
If you did notice any "slack" you would be shooting off in yards not inches. We are looking for a thousands or two.
I would think about the test I recommended. If it double groups then look at mounting first, and bed the rail. If you have the rail off and you see where it is moving making tracks you could have found your problem.
Then once the mounting is covered a scope swap could be in order. I have yet to have a NF issue. But as I have posted before I sure have seen plenty of low cost rail and ring issues. That said I have never used the rail you have.
One thing is for sure. If your combination will not hold a dead nutz zero, you will never be proficient on first round hits. That is gospel.
