There's some info on airsoftsniperforum:
http://www.airsoftsniperforum.com/32...15918-svu.html
From what I could gather, it's a JG manufactured rifle, using a Real Sword SVD T3 gearbox clone. I don't know how accurate that info is though...
And from reddit:
https://www.reddit.com/r/airsoft/com...ck_its_a_cyma/
It says the hopup unit is a Cyma design, so it takes Cyma SVD mags. It is reddit though, so not sure how accurate it would be again...
