Congrats, and welcome to the site!
Looks like a good, reasonable budget, AR.  Nothing wrong with that as your first of many.
Hope it runs good for you!

So far, I have had one problem. The bolt isn't wanting to stay back after the last round on an empty mag. I have checked the gas system thoroughly, and there are minimal to no leaks anywhere, leading me to believe I am getting enough gas. It isn't having any issues feeding, and I have tried mags from no names, to USGI's, to PMAG's. This is using Prvi M855. I got the buffer in a kit from PSA with the magpul acs-l, and it is supposed to be a milspec carbine buffer. Comparing it to my friends, the buffers themselves are both identical, however his spring is about 1/4 to 1/2 inch shorter than mine.  When we swapped, his buffer ran flawlessly in mine, and mine in his. The buffer/spring combo's both weighed in at exactly 136 grams.

Yes it did, and the magazines all ran well with his buffer in my gun as well.

your original spring is likely the issue.  If hes happy with yours and  you are happy with his, then keep his.

Unfortunately, for some reason unknowm to me, he wanted his own back But, I am going to try it with my dads buffer spring when I come back from college next.

You can try "breaking in" the spring. I would say if it doesn't lock back after 100ish rounds I would buy another.

Okay, I put 120 rounds through it on sunday. I plan on putting some cheap steel case through it for volume within the next couple weeks. If after 400 additional rounds it doesn't lock back, I will definitely be looking for a new buffer spring.

Well, another 250 rounds down range. I got a new 10rd pmag and lrho worked flawlessly every time!
