IMO they are the same, there is no reason for a DAO auto to be different for MA. I doubt there is an MA specific SKU for the BG380.
Gunbroker is thin on these, though, so the usual "buy it remotely" wallhack doesn't apply. The guys that are selling them there are running open auctions on them, no buyout price.

It seems they are sold out and out of stock across the country as well. I did find some places listing them for $349 free shipping though.
