    you're nerf gun shoot into cardboard at 25 feet (white tiger v2 rifle) and I'm not bleeding from a stupid cheap made in china foam dart going at 7 feet per second. good guns like my m2 and some others can fire at 80+ and 25 feet< god, i've been aroud for a while here and when I here"25 feet" I'm not exatly like "omg!! that's amazing!" and, you don't make nerf guns. you buy them at that stupid little walmart. Last time i checed that's the place the sold a guy a bike and then the quick realese fell off and the wheels where untrue?if you want to argue more, come over to my house you will use your nerf guns and I'll use my knex guns. I'm not paying for your insurance.

    awesome, i added a stock and barrel extension, a magnification scope made of binoculars(lol) and a bipod. it is the awesome.

    If you still think this build the reaper. It shoots 200 ft and travels at over 75 mph. Try to beat that with a nerf gun.


    dude your pictures are clear but put them in smaller pics and not just show it from different angles im just giving advice
