Not sure if this is what you're asking, but yes, they do have an effect when they are available. Try out both grips on the Reaper DMR - the difference between the standard grip and the advanced grip IS noticable during full-auto fire.

The problem is that aside from the VS CME, I don't know any gun where the difference, even if noticable, is actually USEFUL. That is, if you're firing the Reaper DMR full-auto, you're either within 20m (and don't need it) or else you're at longer range and should switch to semi-auto fire and use iit like a Battle Rifle (i.e. a demi-sniper). In neither case is the advanced grip genuinely useful. The same goes for the SABR because it only shoots a 2-round burst to begin with (and the recoil is almost 100% straight up vertical anyway.)

That all said, the best place to use a Forward Grip is on a Sniper rifle. The tooltip doesn't say it, but it reduces gun sway. It still moves, but on one of the rapid-cycle bolt action snipers, you cann throw on a 2x Reflex sight and never have to hold your breath because with a grip the sway is low enough to land headshots over 80m even without it.

That said, the VS CME is the only "long range" (i.e. has an advanced grip, compensator, and high velo ammo available and does higher per-bullet damage, like the Reaper or SABR) Assault Rifle that remains effective when firing full-auto.

I have none of the LMGs that have the advanced grip so I can't really say for those. For Carbines, you're better with the Laser Sight, pretty much always.
