Home Forums Hunting & Shooting Hunting Rifles Help. Year of manufacture. Rem700, .280 Mountain Rifle.

I just did a bunch of research when it comes to serial numbers and Barrel codes concerning the Remington 700.

I have a SUPER CLEAN Remington Model 700 Mountain Rifle chambered in .280 Remington. It doesn’t have 50 rounds on it. I will post a picture bellow of the “C” Prefix serial number and barrel code.

Best I can tell. It was manufactured in March of 1990.i could be wrong but that is the reason for my post. What’s throwing me off is the double “K” code on the barrel after the “A” month of manufacture (March).


Now my next dilemma. I have entertained the idea of running a .280 AI reamer into it. Pillar , bedding and free footing it.

Then again part of me screams “Don’t do that to a super clean, all factory .280 Mountain Rifle”.

If the assembly code is AK, that would be 03/90. KK is probably a double strike.

I would certainly try it out "as is" to see how it performs, before I would consider making any changes to it!

100% What if it shoots one ragged hole groups at 100 yards, why would you mess with it?

My .260 Rem Mountain shoots much better bedded and free floated. If that .280 was mine I’d shoot it as is and if it wasn’t satisfactory I’d float it with some business cards to see if it improved. If that helped I’d float and bed it but that’s as far as I’d go. Those old Remington Mountain Rifles are a favorite of mine.

Don’t screw with the rifle please! You won’t find any big game animal that will know that it was smacked by a righteously loaded 280 v one with wider steeper shoulders. I’ve had both and still have the 280 SAAMI.

Don’t do that to a super clean, all factory .280 Mountain Rifle...

^^^This^^^

And I’d see how it shoots first before I bedded the action or floated the barrel.

Forget the AI part for sure.

If you don't like the way it shoots just sell it as the original 280

I'm in the "Don't dick with it" camp.

Just because a bunch of experts on the internet think you need to devalue your rifle by customizing it doesn't mean you have to. Shoot it if it doesn't shoot as well as you like. Sell it. A nice one like that probably bring 1200+ maybe alot more on gun broker..mb

I had one. It was wonderful as is. Gave it to oldest son. He turned around and sold it for pennies on the dollar. Will do anything you want it to.

Or you could sell it to me.

I'd check the torque on the bottom screws & see how she shoots first. Beautiful rifle you have there. I had one when they first came out in 7x57 caliber but sold it when I got into collecting the 700 Classics. Probably the best shooting & handling 700 I've ever owned. Good luck on your decision.

I have the same rifle and it shoots really well. I wouldn’t modify it.

Thanks I just bought a very minty 1968 vintage BDL in 7mm Rem Magnum. It's the same year I bought my BDL in 270 that I hunted with for forty years and gave to my youngest son. I plan to have my gunsmith put a Decelerator Pad on it, remove the iron sights, put a Leupold 3.5-10x50mm scope I just bought on it with Talley rings and have him adjust the trigger to 2 3/4 lbs. My hope is that my son wants to trade my 270 back which I will do in a minute lol! If not this will definitely work for me.

Returning to the original Remington date of manufacture question and correct answer provided. With a caveat applicable to all Rem barrels with "relevant" nomenclature. The possibility of a barrel swap. Evident where the barrel is obviously non-original. Not necessarily such where a factory marked barrel is installed on a Remington receiver 'not of origin'.

While instances of such are less likely today, there remain a quantity of Rem rifles reflecting incorrect factory build code dates! The rule emerged, where evidence is in apparent contradiction of the code shown, less likely the "rare factory variation" of hype, than of a simple era barrel swap. My 'belief' that a Factory re-barrel did not code any replacement work and of course, any factory barrels installed elsewhere the same result! This latter bit of factory non-code info, is only my belief.
And now that you're sufficiently confused...

Happy New Year!

What the hell was that?
