Alright. So i have a request; I have seen a few mods for the BB Gun, and some are pretty cool, but not what I was searching for. Specifically, I want a new "BB gun" that acts more like a pneumatic rifle, similar in design and power to the Tihar rifle from Metro 2033. http://metrovideogame.wikia.com/wiki/Tihar This weapon was definetley my favorite in the game, and I would love to be able to use something similar in one of my favorite games. I do not necessairily want or need an exact replica of the weapon, just something along the same lines; A fairly combat-capable air rifle, with either a fully-functioning pressure system (I do not expect this, but will be more than ecstatic to see someone attempt it!) or possibly even just a single-shot weapon with a long reload time to simulate 'pumping' the air-resevoir. Thanks in advance to anyone who even just takes a look at this request, even if it's just to say "Huh, that's a cool idea!" And a big thanks to anyone who even attempts this! Your time is appreciated..
