Not sure what you mean by risers came with. If you get the proper front flip up, then zero the irons first. If you get the Bushnell TRS-25 RDS you'll need a riser for it to cowitness with the flip ups. Amazon.com sells the UTG riser which works well and is only $10. Their medium height riser gives you absolute cowitness and the tall UTG gives you lower 1/3 cowitness (which I prefer). If you already have a riser for the RDS, see how it works.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
