I was going to mention this to you devs when I saw it in the demo, but assumed it'd be fixed. If you aim up at the sky (or anything brightly lit) while using a sniper scope, without zooming in, you can see your weapon as well as the scope itself through the lens. I assume you are taking the player's view and just superimposing it over the eyepiece with a nice shader to make it appear that you can see through the scope, however you forgot to remove the player weapon from the image. It's not gamebreaking but it is silly.
