Guys, I need some info. This seems to be some impossible thing to find for some reason. I've currently got a complete MK13 mod 5 rifle and kit, minus the MK11 can. I've got the correct barrel blank for it waiting, but can anyone specify the correct info the the gate latch cuts on it? Is there a blueprint for this anywhere? I'm aware of Red Bull armory and what not, I don't want to ship it however. I've got a very experienced rifle builder here that can do it, just need the specs.
