Hey there gang! So I’ve recently wanted to try weird fun setups and I really want to try the .410 slug rounds on the lockwood mk2. But in the page it says “Unlock at NONE level 1” (as you can see in the photo) and I wanted to know how I unlock it. I know that usually when it says that it’s on the BP pages but because it’s older it isn’t. I also checked the armory and it wasn’t there. Any advice?
