I've started to feel bad that this thread hasn't gotten any responses, so I'll offer a few thoughts, even though I haven't owned the exact model in question:
- I had a DPMS "LR-243" for a time, was a very good shooter, needed a new trigger.
- I tend to favor a Dtech 243WSSM over that LR-243, but brass is harder to come by, and of course, the upper is a lot more costly.
- I've had several AR-10 pattern rifles, never have I thought that any of them were well balanced or "handy." The extra length and mass of the AR-10 action is heavy. Maybe I'm too used to AR-15's, but I just don't get there - that's my only disappointment with them. However, I'm sitting on two partially assembled lowers and uppers, thinking about a 6.5 Creedmoor...
- It's pretty common that DPMS rifles, despite their relatively low price point and neglecting any lack of "beauty" or "refinement" to the beholder, shoot pretty d@mn good. My 243 version was a sub-moa rifle from the bench, all I did to it was convert it to free floating and drop in a trigger. I had a few of their AR-15's that have also been sub-MOA. There's a contest thread on Predatormasters.com where guys shot six 5 shot groups on one piece of paper, the top spot is held by a stock DPMS Sweet 16.
- There's a teeny bit of risk in reselling right now. The market is flooded with rifles and parts since the tide has subsided after the last couple of years, so if you don't end up liking it, it can be a little harder to resell without taking a hit.
Check the box for weight and resale mentally, and I'd venture it's a safe bet that you'd be happy with the LR-308.
