Nobody on ingo seems to like dpms panther but I was looking into a entry level ar and i bought one from Plainfield shooting supplies (5.56) with a hard case and 2 mags for $629. (brand new plus tax) and i have NEVER had any issue with it. But i do understand there are a lot more experienced guys in here that have good reason. Everyone wants a spikes or rock river arms. Some just can't afford it. Plus you can build it up yourself, for me that was as much fun as shooting it.
And you can't go wrong with the Colt 6920, especially when DSG is selling them for $944!
