I can't see the fault in the forum. A member entered his rifles in the registry and that was it.
SKSboards and SKS-Files have quite a history jstin. Many members here are banned over there. Go ahead and try to post anything regarding this site or the weebly chinese SKS guide over there and watch how quickly the text turns into these markings: ******. We are 100% censored over there plain and simple and have been accused of simultaneously 'stealing' their data at the same time we just 'make stuff up'. Which is it?! It can't be both at the same time!
The survey posted over there is NoytaCCCP's from Canada and is unfortunately rife with guns that either have refurbished and swapped receiver covers or outright fabrication by the person entering the data into the survey. With no way to verify the entries, who's to say what's what?
The survey they did was a noble cause, but w/o second parties being able to verify the data via at least photo evidence, it's simply not all that useful I'm afraid.
