Re: Surgeon RSR Pics
There are a few key differences that I would really single out that I thought about when making a similar decision.
1) The RSR is made from 416 stainless instead of 4140 chrome moly even though the bolt for both is made of 4130 (action spec list) or 4140 (surgeon verbal) depending on which info you get.
2) The RSR requires you to separately purchase the rail and the rail and lug are pinned instead of being integral. For 99.95% of shooters out there, this really wont matter. The pins provide excellent performance in both alignment and recoil tolerance for consistent results. For many people, spending the extra money to have these parts integral to the action simply is not -strictly speaking - neccessary.
3) Tolerances for most of the critical areas are identical. Bolt to receiver fit, for example is still .0015. The bolt itself is identical (e.g. the SAME part) between the RSR and 591.
4) The 591 offers a longer thread length for the barrel (.954 vs .700) and the integral lug is thicker than the RSR (.250 integral versus .241 pinned). I believe the overall action length of the 591 is slightly longer by a quarter inch or a little more than the RSR.
I guess the way I would summarize it is:
The RSR is a 700 clone that you are buying and knowing that the bolt is high quality and the whole action will arrive "true" from factory with square faces and ready to be mated to a precision barrel.
The 591 is for someone who is willing to pay a premium to know that the recoil lug and scope rail are machined together with the traditional reciever from a single piece of billet. Together with slightly longer length of threading for the barrel to secure to, the 591 offers a super stiff custom action packed with features that is still substantially similar in key dimensions and features to the remington 700.
In my case, the RSR offers a more economical option and the integrated this and that just was not worth the extra money. Thats not to say that you shouldnt get a 591, but you should decide why you want one or the other and it should meet your need.
Either way, its hard to go wrong with an action from Surgeon. Despite how much I grumped at them for thier customer service in the discussion about nitriding, these guys are good people who make good parts and you are in good hands.
