I have shot one but I do not own one. I do own a DPMS AR15, actually I have 2 DPMS Lowers and 4 different configs of uppers. You may pay a little more for the DPMS parts and pieces but they have great quality it appears to me. There is also a store 5 blocks from my office and they have just about everything in the catalog in stock and they are really nice people to do business with.
I thought that the Bushmaster 308 was quite a bit cheaper than the DPMS and Bushy quality and customer service is 2nd to none.
