Hi Poor Grendel like D4rk said.
You have to do certain things on levels I.E killing target specific way.
Do these weapons still have little padlock when checking progress of weapons? If so then this hopefully is the case.
I was same I was thinking not again. I've got history with S.E and bugged chievs.
It's same for some pistols & secondary too.
I've just unlocked both today.
I found info on TA under weapons chievs. It says what criteria is for unlocking weapons.
Good luck
