Does anyone have any experience with one of these? I have been wanting an AR in 6.5 or .308 for a while, but the weight has been a turnoff. These solve that problem. It appears they shoot subMOA. I am leaning towards the 6.5 as apparently itnis going to stick around for a bit, though I would have to buy everything for it. I like the added range of the 6.5. DI or gas piston? I would like to be able to use it to hunt and play on the range once in a while.
