Ready to buy a scope and need your opinion!

I have a POF upper p415 and spikes lower.
I’m finally ready to buy a budget scope for my ar15. I don’t know much about scopes other than what i’ve read. I don’t have any experience with them on rifles so, this will be the first for me. I have a couple of links to optic planets website.
I would like your "expert"opinion:) on the 2 scope that I’m looking to buy. They have specs on both the scopes on the website and it would be super duper nice if you guys can tell me the pros and cons between the 2 scopes.

[b]On the redfield spec: Elevation Adjustment Range (MOA): 56
Windage Adjustment Range (MOA): 56 What does this mean? Is this good? How is this comparable to the Nikon prostaff?

Also what about the eye relief? Which one is better between the 2?[/b]

To mount the scope on to my ar i’m looking into buying the Leupold Quick Release Weaver Style QRW Rings: Quick Release Weaver Style Rings 30MM Low Gl or MT. I don’t know what the difference between the GI or MT?.
In your opinion is the 30mm mount to low? Or should I stick with the 1" mount?
What do you guys think about this mount?

If there is any other brand similar to what i want would be great.

Thanks.

If you really want to find the optic that will make you the happiest, you need to clearly define your intended use and expectation.

For now I want to get comfortable using a scope at the range (100yrds for now)and maybe down the line to hunt with it.
