well first of all its a oow reciever, with a hungraian feg sa-85 kit, i was going to use a tapco g2 fcg, but the bolt carrier and bolt doest even lock the hammer down when pulled back, i tried a boltcarrier and a bolt from a romanian and the same thing, are the pin holes not in the correct spot for the hammer pin or something on those recievers.  I found that some people had problems with the g2 and oow reciever, but never what the problems were.  Can someone enlighten me cuz an orginal fcg seems to work in it?  Would and rsa one be the answer?

Never seen a problem with that combination .  Check disconnector and hammer spring for proper placement .

yes it was all placed in there correctly, i guess i should have said the boltcarrier/bolt doesn't even push the hammer down far enough to lock in place

Is the sleeve installed?  The G2 will not work without it.

yes the sleeve was installed
