It depends, I was using an AFG (first version) plus a two piece VLTOR Bipod. The gun front weight is not a problem in my opinion because it is still a pretty well balanced and light rifle. Also the AFG is not as low as most foregrip and I tend to find it useful when prone in messy environments (trunk, hard twigs, etc).
If you had an M14 EBR then I would go for a foregrip without a second thought because ALL the weight is in that massive front RIS... and I think the one who designed that must have been either high, drunk, incredibly stupid or all of the above to design something with center of mass right next to reaction hand.
