Is anyone aware of a place to buy a barrel shroud for a mk760/s&w76? I want to find one that I can cut down, along with a barrel to shorten and thread, in an effort to make a suppressed upper that isn't overly long. I have seen the one on Gunbroker but am hoping to get one for less than $300. Of course if someone knows of a place to buy a shortened barrel and shroud that is ready to go, I'd be interested in that too.
