Rem 870 forearm slide removal

[chefhunter34 1]

Does anyone near Bergen County have the wrench to remove the ring that hols in the forearm slide? We bought the pistol grip for it but cannot get this off and do not want to ruin it. Any help is appreciated, I just need to borrow or come to you and change it.

 

Thanks much in advance

easy to remove the nut with needlenose pliars, depending on the age of the gun it may be difficult to get the tube free but can be done.
