I know there are restrictions on rifle barrels in Maryland. The barrel has to be a heavy barrel (which I can't find a solid definition for). I was wondering if anyone knew whether the Gunner Profile barrel from Faxon was legal in MD for an AR rifle build? They define Gunner Profile as:
Gunner Profile - hybrid of Government profile in rear and Pencil profile in front. Retains weight at the rear to maximize heat resistance and mitigate whip, and removes weight from front of barrel for maximum versatility.
