I have been shooting my TRG bipod a while now and love it. I do have a problem with it though. When shooting in grass its awsome but on gravel and other hard surfaces it slides forward as I shoot. I have to keep creeping forward to follow it. I am a little worried for this winter and shooting on ice. Does anyone have any experiance and recomendations. I was thinking of like some slip on rubber feet , anyone make any? I realy dont want to go and drill holes to attach anything.
