The RS type 56 is very nicely made and the quality of the internals is very high. However it is absolutely useless, at least for reenacting/milsim games, which comprise nearly 80% of all games in Russia. Unless, of course, your team is modeling Afghan guerrillas or some African tribes.

The last line of DiBoyz AKs has been noted to be somewhat better than the last line of CYMA, so go for it!
Concerning your question to me - are you sure? Those are nice guns, but they are by no means cheap
A kit (externals plus a mag) is about 650$. People still buy them for that price, though. The guys can't reach the economies of scale of the Chinese manufacturers.

Poor guys, that would suck. In Soviet Russia (lol) the allowed speeds are 172 m/s for full auto and nearly unlimited (>240) for single shot rifles, technically incapable of having auto or semi auto fire and having mags of 10 or less. In practice, speeds above 160m/s are reserved for the heavy machine guns for realism purposes. Normal AEGs are typically limited to 135 m/s by standard game rules.
Also, according to what I have heard Bore Up is not useful for speeds less than 120m/s. A standard Guarder kit is way to go IMHO.
