Very very nice!

And they can be used pretty much for the Soviet invasion, Civil War and current conflict. The AK47, AKM etc they will be in use for decades and decades to come, perhaps even till the end of this century. A lot of countries still produce them with the original materials (though recently Russia started making them out of some plastic material, not sure what).
Put it this way, across the Third world, including Afghanistan, militias can often be found using bolt action Enfield's, Mausers etc from the Inter-war to WW2 period. Been quite a few insurgent snipers found using vintage bolt action rifles used during the world wars because accuracy/range wise they're still, almost, if not just as good as what we use today!
