Evanix MAX-ML .44 cal BullPup review

Someone really needs to send Evanix a dictionary with the pages folded over at shroud and baffles. Why are they so incapable of creating a shrouded barrel that actually makes their guns quieter? Out of all of the Evanix guns that advertise a shrouded barrel, not one of them is quiet, even in smaller calibers. 

I get that a big bore is never going to be suitable for the back yard but it is quite likely that someone might want to use a .22 or .25 at home.
