Yes Sir I know that they are cheap, but you´re missing the point. It wouldn´t be “self made” and besides, I want one in 30-30Win. You are talking to the certified DIY guy now… The whole idea is to be able to use one gun as a double shotgun or a combo with just an “insert” barrel, with just a fraction of the prize of an IZH-94 with both double shotgun barrels and a combo barrel.
