Posted by ronboyThank you, bro :)
Hello, NightBerkut. Yes, that's my Youtube channel. Those weapon models were extracted from Titeuf's Rtcw mod called The Dark Army, but a few days ago he released some addons. The weapon skins are included in one of them.
You can find Titeuf's addons here: http://www.moddb.com/members/titeuf-85/addons
