Didn't know where to post this, but this is a video game that I have been playing as of late. Its free, but Steam was actually selling full access to all the guns for 20 bucks a few days ago. Ill grab it next time a sale pops up. Anyway the game actually shows you how to field strip and detail strip firearms; along with showing you how the gun operates in slow mo, xray and cross section view. In competitive mode you are supposed to completely disassemble and reassemble the firearm faster than your opponents. I think it is a good tool to learn about guns, and to teach kids about guns. Me and my kid have been trying to see who can strip a 1911 to the frame and put it back together the fastest. http://store.steampowered.com/app/262410/World_of_Guns_Gun_Disassembly/
