Hi Austin and welcome. Unfortunately, this model is not MD compliant. MD required a Heavy Barrel profile (HBAR) as listed under "Rifles" here: https://www.budsgunshop.com/feeds/state_reg/maryland_restrictions.pdf --------- Cheers and stay safe!
An HBar Under the handguards diameter is 1.0" from Barrel Extension to 1" before gas block, there is a 10 degree chamfer to a diameter of .850" - Gas block diameter is .750" for a length of 1.875". It steps down to .740/ .745" all the way to the muzzle crown or threads. - Target muzzle is 11 degree crown. - Threaded muzzle is .620" long by .500" diameter. Threads are 1/2 x 28tpi for a length of .500" / .510". Since this is a socom heavy profile barrel it is not MD compliant.
