Not going to help unless it's permanently attached.Attach a suppressor.
Keep in mind that you'd need to ditch the factory flash hider to do what you're suggesting, and would not be able to attach a suppressor later on.This is the best way to get it to be an MD legal SBR that I can think of.

I saw that video, I read the comments and its 27.5 inches long with the stock fully extended, so for Maryland residents it needs to be 1.5 inches longer. I guess a barrel extension or a longer muzzle break
