Re: Receiver question
Both Rem.700 and Sureon RSR are 1.062 @ 16 T.P.I., so technically it can be done. I take it by the action has been "Mapped & Trued" you already had a barrel job done and now you have a new action and want to move it over and continue to shoot until you can save for a new barrel for the Surgeon? What your gunsmith could do is pull the barrel and measure the tenon length of the Rem. and the RSR, hopefully with the RSR being longer with the addition of the recoil lug, he could then face off the shoulder of the barrel that the lug goes against to restore headspace. This is not the best solution at all, just a way to swap barrels with the same tenon diameter & thread. There are problems that can arise, only you can determine if the risks out weighs the savings.
