As was suggested before, read the stickies at the top of both the AR general discussion and technical discussion pages. There is a wealth of information there and will answer most if not all of your questions. Depending on how you've run your DPMS so far, it may have functioned flawlessly for you. The vast majority of the issues you will hear about with DPMS may never manifest with you if you only shoot from a bench or use it to kill paper and beer cans. (There is nothing wrong with this either)
Just to list a few issues with DPMS:
1) Quality control has been uniformly poor across the board
2) Marked as a 5.56 chamber when it is acutually .223 (big difference in the two)
3) BCG are not properly staked
4) Improper extractor insert and spring
5) 1/9 barrel (an issue if you shoot rounds heavier than 62 grn)
6) Barrel steel is lower quality than TDP requires
7) Castle nut not properly staked
8) Incorrect FSB (on some I have recently seen) for a flat top receiver
9) Should run a H buffer
Those are just a few I can remember off the top of my head. This does not mean that your DPMS will not serve your needs. I would have my doubts about it making it through a high round count training class without some issues.
