Not a dumb question at all. They are both Benjamin brand. I just took my 1/2UNF Donny adapter off the Kratos and tried it on an Armada shroud and it doesn’t thread in very far. Funny thing is I could have sworn that I tried a short shroud from Tim Hill I bought for a marauder on my Kratos several moths ago and I thought I remembered it fit..... but maybe I am mistaken. I would verify that but I have almost everything packed up in preparation for moving to our new house and my wife would strangle me if she saw me unpacking boxes and getting stuff out at this point Hahahaha
