You could, but at the risk of fucking up their eyes, I wouldn't. Then again, the only NVG's I own, are the ones from MW2, which work quite well actually. But yeah, I want a lot of weird stuff. As soon as I move, I'm buying a biohazard needle container to keep my BB's in. What I'm also going to do, is put red juice in it, and drink out of it in public, to freak people out.
I have a pair of those silly infrared googles, from the same company, and they work but depth perception is effed up, and mine have a giant cystic plastic eye on the top for the camera so you cant use it with a helmet.
I'm also buying some syringes and crap like that for a movie I want to do. In fact most of the stuff I'm planning to buy is for a movie I want to do. List includes
-sandbags
-syringes
-shit loads of spring g36s and surplus bdus
-spent brass
-eotechs fucking everywhere
I have like 30+ things on the shopping list but I CBA to list them all, since I'll probably only be able to buy half of that stuff anyway.
