They original pads are indeed Limbsaver pads. A guy who shoots where I do had three of the rifles with bad pads, and Remington sent him three new stocks that have a different recoil pad installed, but they are the same identical stock as the originals. He said all Remington asked of him was the serial numbers and calibers of the three rifles to check for him actually having the rifles while he was on the phone. This happened about two months ago.
He had removed the screws on all three stocks and found all of them to be glued. That is when Remington stepped up.
He told me that one day a few weeks ago after seeing the suggestion on the internet that he tried heat from a hair dryer and all three pads came loose. So he called Limbsaver customer service to see if he could buy new pads for the stocks and they told him during the conversation that the pads were a result of a bad rubber mix from a supplier and they asked him to ship them one of the pads he had removed.
He promptly got three new pads from Limbsaver at no cost. He said they screwed right onto the stocks and fit perfectly. He also told me that the three pads that Limbsaver sent to him in factory original store packaging were for Tikka T-3 synthetic stocks. And again they fit perfectly.
