I was playing the video game Army of 2 and since it has a P90 as a weapon I naturally used that. When you earn money in the game, you can buy new parts. They even have the Magazine Parts Quad Rail in it. They also have something called Kowalski Dragoon V3. This thing is awesome looking. I don't know what it is supposed to do for the weapon. I thought it might have a laser and light built in to it, but it has rails on the side for that. I think it might be something cool they made up for the game. I could not find anything about it on the internet. I took a picture of my tv screen, so I apologize about the photo. Hopefully I didn't mess up posting the photo.
