Beware of scammers.

1962 to 1968 in ADL form. Beyond that your info is of little help. What info is on the barrel?

Everything you need is on the left hand side, U E P 30 / 314143.

U is the symbol of the final inspector
E stands for October
P stands for 1967
30 is the symbol for the assembler
314143 serial number confirms the year 1967 when compared to others in the same range

Stock checkering confirms ADL ...

The woox reference guide I believe is AI produced junk. Run away from it and never look at it again. Its totally wrong on most aspects. The rifle you refer to is unique for one reason or another. Custom shop guns are NOT date coded. Employees could inspire how the end product looked. I wouldn't ...

These triggers come under great scrutiny. Safe handling always trumps everything. Of the many I have and know of, I've never seen the proof to make me concerned. The one and only thing to remember is to keep these triggers clean clean clean. Did I say to keep them clean. And dry! NO oil. Dry lube ...

Unsure where you got 1977 from. The serial number places it in the very early 1990s, likely 1990. This may be a rifle made for a Remington employee. First one I've seen marked so. This is either the assembler or inspector.

I think maybe P as well. so...P B M

P could be June, but B is 1955 and there was no rifle model to assemble in Canada at that point. And the practice ended long before 1981. So that is out.

B could be January and M could be 1965. This is the only feasible solution. In this case, the P (and hell ...

Is the first letter an F or a P? Look close for incomplete stamping

Fair pictures, but we need one of the top of the barrel ahead of the rear site. RD is not a date code

Perusing the rack at larger local shooting sports store during this time turned up a couple of uncatalogued items from Remington. One for sure was a snowcamo stocked stainless 22/250 varmint type rifle and an odd stocked 597. Both were new in box. Didn't kno at the time they mite be limited models ...

Typically, the bolt handle should be blued. Important in this case to is be sure the bolt matches the serial number.

The symbol is super likely the assembler. Due to the limited space and the fact that the date code letters are stamped separately, the assembler and year date letter overlapped.

April or May, 1962, the first year of the 700 if 7825 is the serial number! Should have a 20 inch barrel. Should have the letters C or K and K on the barrel ahead of where the serial number is.

Looks like September, 1950 going by the serial number.

The serial number puts it late 1978. Should have a barrel code of D or E Q.

O M date code and serial number put this rifle at July 1965.
