no it does not have the required heavy barrel I would check with your local FFL for MD compliant AR 15s

James, no this is a copy of an enumerated banned assault weapon. This S&W is MD compliant >>> budsgunshop.com/product_info.php/products_id/23979/smith+&+wesson+11616+m&p15+sport+ii+semi-automatic+223+rem556+nato++16+10%2b1+6-position+black+stock+black ....Per MD State Police -- Smith & Wesson M&P Sport II #11616 Not Banned, Does not meet the definition of a copycat weapon or the definition of a copy of an enumerated weapon, Heavy Barrel Version, 9/17/2021

James, no Sir it is not. I would use Black Anchor Armory comprehensive list of MD compatible & non compatible AR's as a guide -- blackanchorarmory.com/md-compliant-ars.html

The SW you listed is not MD compliant this Mini 14 is (you'd need to have buds remove e the 20rd magazine, but then its legal)
