Beware of scammers.

401XXX would be likely late 1956 or into early 57. Quite possibly a re-barrel. Are the sights nice and level?

[ "CA" this would be April 1954

May we see a picture of the barrel date code and the first 3 digits of the serial number?

Thanks for that info 6ooRemGuy. On another note, do you collect 600s/660s? Do you have any 16 1/2" examples of either/both? t


600s mostly. Have a 660 in 350RM only as I believe it was rarely fired if at all-was my first 350RM. I snap up older odd 700s as well. 2 in a 7mm like you but the 7mm ...

I heard for sure a case of 5 made it to Canada. Quebec area IIRC.

Sincere condolences. June 1969 no doubt about it-everything lines up. As built rifle. Full 24" stainless steel barrel. Enjoy it!

First year, March 1964 for a build date. The internal mag box is installed incorrectly causing the major warp in the trigger guard. It has had the trigger recall-the V on the trigger tells us that. You can still find trigger guards that aren't too warped. The rib is a bit tougher. You mite want to ...

Would tend to believe the March, 1966 build date. While the receiver serial number should really be far closer to 190xxx, it is not uncommon to have a receiver a few months older than the build date as serial numbers are added when the receiver is built, not when the rifle is built.

It is the barrel markings you are looking for to date most. The "RR" or any letter(s) before the serial number is only a clue. XH would be Dec., 2013. Mid 1999 to late 2001 the date code on the barrel was suspended.

Just a few more than 3500 M600s were produced in 35Rem. It is the second most rarest calibre, unfortunately dropped from the later M660 lineup and and almost completely from Remington's calibre list but for some custom Model Sevens years later.

Shown below is mine

Very legit

Just as the A stamping is incomplete, the P is incomplete as well. It is for sure a P with the bottom arm swooping up.

Barrel date code should be "(E or R) and W". 98 would be the assembler. U could be the final inspector. There would be, in this year, 4 symbols/markings and yours mite read U EW 98 or U RW 98, with I believe, your month/year EW or RW being 2 separate letter stampings of the same font as opposed to 2 ...

UE makes no sense. Serial number dates it October or November of 1972

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 ...
