A little more time in the gym.There are all kinds of tools and such nonsense to press down on the delta ring to get the handguards off,they are junk nothing more.Place the butt of the rifle on a solid surface and press down on two sides of the ring evenly,with the other hand remove the top handguard....simple.Most folks who cannot get them off simply lack the grip strength to do so easily,keep at it no need for oil,graphite or other ubrication.
