I can't get the link below to work for this but according to the article in Russia anyone without a criminal history or record of mental illness can buy a shotgun pretty easily....however there is a five year waiting period after purchasing a shotgun before Ivan can buy a rifle. The Rooskies have come up with a work around on this. They have necked up the 7.62x39mm and 7.62x54mmr cartridges to take bullets that almost give the case no neck at all and chambered standard Russian firearms for them. They get around the rifle restriction by using Paradox rifling, that is only rifling the last few inches of the bore. Russian law apparently does consider paradox rifled firearms shotguns and so far the Russian government has let this ride but the Russian gun and ammo manufacturers have other options waiting in the wings in case their 'gubmint bans the paradox rifled guns. In the link I posted on the Soviet Arms section about loading clips in the SKS the Rooskie doing the demonstrating was using an SKS chambered for one of the new rounds, 9.55x37mm.
Sorry again about the link.
