Hey Brian,
I’ve had the VG2 on the rifle for a few months now, it is holding up well and is certainly a lightweight option. As far as barrel contour choice, I would run that by stockys to be sure. I can tell you that I had some fitting I had to do on mine, which had the stock varmint contour barrel from Howa. Main areas being barrel contact within the first 3" from the action. My guess would be that the Sendero light profile would fit better, but again I would run that by Stocky's. I also had more fitting work around the trigger as I had swapped for a Timney.
One other thing I will mention, fit and finish of the VG2 leave a little to be desired. The two "shells" where the molds come together show a bit of a line at the cheek weld area, nothing that cause any felt discomfort, but it is noticeable. There are also some spots where you can see some areas did not fill completely with carbon. Don't get me wrong, I like the stock, but I have an AG composites on another rifle, and the finish of the AG is far superior to that of the VG2.
I can try and take some photo's and attach if you are interested in seeing.
Thanks
Clayton
