Awhile ago, my friend showed me Pimp My Gun. This site has a Flash driven app that lets you assemble the weapon of your dreams. It is basically a drawing program that has a library of hundreds of firearm components. There is so much room for customization. I tried it out and came up with the following guns:
So we sent a gun salesman to your mother's house, so you can nag mum to buy a magnum!
So we put a flower in your gun, so you can have a pistil in your pistol!
So we told you where Karla Homolka lives, so you can snipe her like a sniper!
So we sent some paratroopers after you, so you can shoot at their 'chutes!
So we put an ad in Soldier of Fortune, so you can buy magazines from a magazine!
So we featured your gun in The Matrix, so you can see it get reloaded in Reloaded!
So we put a target sign on the stove, so you can take your range to the range!
So we put you in touch with this guy who really knows his guns!
