I was considering selling my CMMG lower for a BCM or DD from Grant, no particular reason other than personal preference. Is it worth the aggravation and extra money?
In my opinion, no. For the most part, a lower is a lower. As long as it is not some known cheap problematic lower I wouldn’t be concerned with it. Someone once said, when it comes to lowers, it’s all in which logo you like best. The upper does all the work. Talk about swapping out a CMMG upper for a BCM then that is a different topic.
However, as you say, personal preference. Your call on that.
Aggravation? Swapping the parts? The only snag is a wrench for the receiver extension castle nut.
Functionally as long as the lower is in spec then no, it may not be worth it. I personally would just for the BCM lower. Then have a BCM upper to go on it.
As much as I would love to have your business, I am sure that the CMMG lower is just fine.

About the only thing would be if you had concerns about the components you could get a new LPK… but that’s about all I’d do with it.
Just toying with the idea, I’ll probably just pick up a stripped lower and LPK and build my own.
