VFC URGI GBBR V3 fit S&I Tactical KAC URX4 handguard?

[Rechard]

Hi, wanna buy this S&I Tactical KAC URX4 handguard and fit it to my VFC URGI GBBR V3, do I need to buy any other adapter or rings? or it will go straight on? and what's the difference between this one and the Maddog brand URX handguard?
