If I were shopping for a BCG, I wouldn't choose DPMS. It'd be like putting the motor from a Ford into a Aston Martin. If the SHTF it's good to know it could be used in an emergency if there's a failure and an LMT isn't available.
LMt's AR bolt carrier groups (I've got one in my Mega, and it's definitely a great part) aren't any more expensive than BCM or DD, so I doubt it'll be that much more expensive than a Fulton Armory 308 Titan BCG, which is $289 complete and chromed.
