I don't know if this will help, but one reviewer of the gun called Remington and during the conversation with one of their people, the topic of the freefloat/non-freefloat came up. And the conclusion was that it needed the Stock bedding(Think that' the right term, new to rifles) to cut down on the vibrations(harmonics) of the gun.. Apparently in it's initial development phase, it was found that the 700VTR didn't work well freefloated...
So I'd say replace with an original stock, or find a new one that supports the barrel in the same locations to the same degree.
I'm interested in this gun, as my first bolt action, as it has a nice look, and the Rem 700 is a good platform to start from, from what I've read.
