I'm in the market for an ar15. This will be my first "evil black rifle".

The problem is that I'm stumped on what to get. I'm torn between a m&p 15 sport or building one from psa blemished parts.

As you can see from my two options I'm on a budget. I know that since I'm on a s&w website I'll probably get one sided opinions, but I'd like to know if any of you have experience with these two guns.
