This was a blue switch shot that came with a the Nerf video game for the Wii. The mods that were done are AR's removed and a CPVCre-barrel . Its getting around 35ft flat. If you were wondering the silencer doesn't work and it is just for looks. I don't know what the silencer is exactly I just found it laying around in my dads bike stuff. It also fit over the CPVC nice and tight so I dint have to glue it.
