Join Proxibid.com and see what they really close out at. Remember buyer's premium.
Now if one had an R and put the wrong swivel mounts in the right places, how could it be told from an RS ?
If one had an RS missing the rear receiver sight and changed the swivel mounts to the new style, how could it be claimed it is not an RS ?
Appears to be that, lacking any factory data, there are no answers, just opinions.
