Do some Remington Model 7 actions have an anti bind rail for the right side lug. I have seen actions that had a groove in the lug but there was no rail to fit into it.
Will confirm this weekend. One is at the gunsmith being rebarreled and can't remember on that one. If my memory is correct on the other two, the one without the groove or rail started life as a late 90s stainless 308. The one with groove and rail started as an early 2000s 300 saum
Fwiw the one being rebarelled is a cdl in 350 rem mag but I can't recall if it has the groove/rail or not
