Thanks for the kind words on the mod. I'm glad you like it. As far as a stock version is concerned, you can download either mod version, but the stock game only has 1 periscope mask, so all you'll get is the attack scope view no matter which scope you use. I'm sure there is someone out there smart enough to add the night (observation) scope mask to the stock game, but that person is not me. If you can figure it out, go ahead and package this mod with it and release it as a separate mod.
Now all I need to do is figure out how to make a super cool signature graphic like the rest of you guys have
