Wow, that is pretty damn accurate, even the helmet is correct! Also, a good choice on the AKSU
Concerning the A&K - it is much better than the earlier version of the Atoz rifle (which is now discontinued). Its by far biggest advantage - it can handle very strong springs only with minor upgrades of the other parts. And it beats the price of all other SVD's, which have many more flaws (Classic Army, Real Sword... G&P lol).

"RPK CM 0.51". There haven't been any insightful reviews on the Russian forums on the insides of the MG. Would be interested to hear more about it from you

Don't get the Chinese replica. Even the civilian variant - POSP would be better (4x24 is plenty). Of course, if you want a really good scope, I'd go to the source.
