..ship with their enhanced BCG/Bolts? We all know the enhanced system was optimized for a 14.5" Milspec gassed barrel.

Correct me if I'm wrong but the enhanced system also seems to help out mid length 16" rifles.

So what LMT rifles ship with the enhanced setup if any? I own a CQBP12 which has obviously nothing to do with this but has me convinced LMT produces the baddest AR in the industry.

I don’t think they do with complete rifles, however you can call them up and order a rifle, or upper with which ever bolt and carrier you would like it to come with.
Agreed on LMT being one of the baddest companies.  
They are one of the best.

Most all of their DI ARs come with a Standard Semi-Auto Bolt Carrier Group. You would have to order a 5.56 Enhanced Full Auto Bolt Carrier Group (L7Q3) if you wanted one. They are quite pricey.

My three LMT's have been absolutely flawless.  I love them
