I loosened them 1/2 turn and it was too loose, so I tightened it up again and it seems to be turning fine. I guess I tightened up too much initially.

I really wish they were allen screws instead. I hate these phillips heads.

Now that I've fired it, this thing is awesome! What a great buy!

Unfortunately, its still not good enough to use my red dot, so looks like I need to keep working on my adjustable angled riser rail idea.
