The first one, my 2012 lawgiver was originally a ps2 light gun, which it then built around with 2mm plastic sheets and a heat gun to mould the complicated bits. The second one is another computer game gun which was based on the 1995 lawgiver. A lot easier to alter than the first, so I added some LED lights and painted it. The other 2 are nerf guns. The first is just painted, but the second has LED lights fitted with a switch in the handle.
i find all my base items on e-bay or locally on gumtree, and then with some hints and ideas from you guys, alter them to suit my needs.
if you need any further info, please feel free to ask.
