I am possibly moving to moscow and would like to take my rifles and shotgun with me. Is this possible?

I have a 12 bore shotgun, a 17 hmr, a bolt action .22 rimfire, a semi auto .22 rimfire and a .223 centre fire, all with sound moderators and ideally do not want to sell them or pay for storage wilst I am in Moscow (which could be for quite a few years). Is it possible for me to take them with me and keep them or by being an expat would I be prohibited from keeping guns?
