I just recently purchased used a Remington 40x in 308, this is a repeater action with a 7.62 marked SS barrel. IT comes with the Redfield Olympic rear and front sights, and a palma style stock with the metal insert in the bottom. It has a Serial # 046xxx C, with the proof/makers marks on the right side of the barrel on the left is only this mark - 7.62 Nato. I did get a hold of the original seller, this was a consignment rifle he told us that he was the original owner and specifically ordered it with the 7.62 SS barrel from the custom shop instead of putting on a traditional blued barrel. I'm currently not sure of the age, I should have asked that question but I didnt want to bother the gentlemen it being near 6pm. I will call Remington tomorrow morning to find out that info. Being a repeater I may save the stock wrap it in a safe silicone sock with preservatives on the wood, and update it to a newer BR stock or chassis for BR/F class etc. I keep seeing EGW come up as a suggestion for the 1 piece scope rail but I had thought Warren or another company may make a better one especially for the 40x. At this time I will be temporarily using either a Sig Tango 4 4-14x44 scope, or SWFA fixed 16x scope I have sitting on my 40x in 22 LR. I'm attending school right now so a lot of money is going towards that, when finished I do plan on putting on a nicer scope like the BigSky III, or NF I believe its the BEAST, possibly a Leupold. I purchased the rifle at under $950 roughly, I'm not sure how much the c versions go for as I mostly see XB, or 40 X info available. I apologize for the long read, Im looking for suggestions on the 1 piece top rail for the rifle to mount a scope, I would appreciate it. It has a very nice very short I can guess its in ounces, trigger pull but I wont know the exact until my gunsmith friend uses his tool to test it. I was saving up for a custom action like BAT etc, but I do so enjoy my 40x in 22 and this being a repeater I didnt see many of them so I took the plunge. Thank you for looking at this, if you have a suggestion for the scope rail 1 piece or even 2 piece if that will be better I will definitely look at it.
