Palmetto State Armory has a ton of new models coming out during 2020 and some of the AK47 Rifles for sale should be legal in MD becuase of the diffrent calibers they will be offered in !
Battlefield Las Vegas has one being used and abused on the range. It has a nitride barrel, not chrome lined, and according to the post in the AKFiles, went 17k+, before needing to be pulled due to keyholing. I guess it needs a barrel replaced, but all the rest was reported to look ok. The newer Gen3 rifles are reported to have FN barrels. I think 17k full auto is pretty impressive, IMHO.
