Any AR15 experts out there

Not sure if I would call myself an expert at all, but I did build my AR and carry one every day for work.

check this spreadsheet out, it has all the technical data you could need to make a decision.

Depending upon what you were going to use it for, and what type(grain) ammo you are going to fire I would say go with the MP15. The only real drawback of this rifle vs. the other is that it has a 1 in 9" twist rate. the slower twist rate means it won't be able to stabilize heavy grain rounds. However if you aren't planing on shooting heavy grain rounds and are getting it for plinking purposes go with the MP15. as you can see from the chart it has better quality assurance and manufacturing processes. any questions about anything on that chart let me know.
