Folding stock for 870-500 and 12

I have a full setup ATI folding stock fits the . The instructions say  remington mosseberg and Winchester . Have the front grip as well those instructions say it fits Remington Mossberg Winchester .  Also have 5 shot shell holder attached to the rear stock. All adapters are there for both grips. yes I painted them orange  for visibility in the bush  . I had them on a 870 I carried in bush trapping switched up what I carry now and reversed the 870 back to Wood stock . No use for these anymore.
