Mohsin, this is not legal in Maryland due to not having a heavy barrel. Know it sounds weird but in order for an AR-15 to be legal in Maryland it must have a heavy barrel. Sorry but hope this helps. Here's a link to Maryland's restrictions....... budsgunshop.com/feeds/state_reg/maryland_restrictions.pdf

Moshin, YES! This is MD compliant. It is on the MD State Police gun roster. Quote from roster " Ruger AR-556 #8532 Not Banned Does not meet the definition of a copycat weapon or the definition of a copy, or enumerated weapon in statute. 8/12/2020 #8532 is the .350 Legend caliber version of the AR #8500." Go ahead and order it, you are good to go!

MOHSIN, unfortunately it is not. Details : --- https://rangeusa.com/product/ruger-ar-556-mpr-350-legend-16.38-51-adjustable-magpul-moe-sl-stock-black-hardcoat-anodized
