I have had two DPMS AR-15's. Both DPMS rifles I had were very good quality and shot well. Both were fairly inexpensive too. I ended up selling both rifles to friends, and after a trade, I currently own my original again.

I have a love/hate relationship with AR's. I really like the design of the rifle. They can be had in all kinds of configurations and are capable of shooting extremely well. But, cleaning them and picking up my brass is tedious. I suppose I could just shoot cheap ammo, but that kind of defeats the purpose of having an accurate AR.
