The grip plugs that fit the standard A2 grip DO fit the overmolded grips. However, they are not that tight and it would not be hard for the contents to be released. Here is a green Hogue with a plug. I can't remember if I got a grip plug from DPMS or somewhere else, but I have tried at least two brands and one was tighter than the other, and DPMS sells multiple variations I believe (Marsh plug). All my Houges have them, but I don't really store anything in them. The lip, as well as how loose they were told me I would come off without much help and under heavy fire and heavy contents, they would probably work free. I would like to see the Hogues with a built in hard plastic container cover. The greenies are available to the public. RRA had an exclusive agreement with Hogue and could not sell them separately, but I hear now that they do. I ordered my greens directly from Hogue. The first clerk did not know what I was talking about, and then was under the false assumption they were not available for general sales. I persevered and called back a second time. The second clerk had no problems and knew her stuff, she sent the green grips pronto. You should have no problem ordering them unless you get a stupid clerk.
