King arms + G&P WOC

I have a GBBR GP M4, and I wanted to use a KA replica troy rail on it. Do they fit together? Sorry I have to make this clear before I make the purchase.

EDIT: Does the WOC has the same flash hider as AEG? I'm trying to get this troy CQB-SPC Silencer as well if it's compatible with my WOC.

Thanks in advance
