Nylon 66 help


January 6, 2003, 10:02 PM
Hello all.
I have a Remington Nylon 66 that I am trying to determine the date of production on. The letter code of the barrel shows that it is either Oct. 1964 or Feb 1973. I know that 66's built before 1968 have no serial number. My question is: Where would I find the serial number on a 66? I've taken off the barrel and receiver cover and the barrel is not stamped with anything that resembles a SN and the only number I can find is printed, not stamped, on the left side of the plastic stock/reciever housing in yellow ink. Is this the SN or is this a pre '68 production? Do I need to further disassemble a 66 to find a SN?

Thanks for any help. It'll be interesting (to me anyway) if this .22 turns out to be older than me and is in better shape.:D

I just read this post and I like Nylon 66's I have no idea and dont care where serial number is but PLEASE DONT FURTHER DISASSEMBLE GUN. This is the hardest gun to put back together Ive ever seen. Even harder than a 742 Remington. I think you just were supposed to remove reciever cover and blow off dirt gently with air. Clean bolt face with A LITTLE solvent on tooth brush and use pin oiler on steel parts. Nobody likes to put these back together you will have a box of useless parts.:what:

Thanks Gordon.
DONT FURTHER DISASSEMBLE GUN - you will have a box of useless parts

That is exactly why I didn't go further than the cover and bbl. I'm curious but not that curious. I have no intention of getting rid of this piece so the date is just for my own general knowledge and so when my son takes ownership he can tell his kids how old it is.

You have fine rifle. I've been shooting them since the 60's and have owned 8 of them. I think they are some of the finest .22 rifles ever made.
Don't be intimidated by the innards of these things they really aren't that difficult to assemble again once you have them apart.

My suggestion is to keep it dry. They were designed to function without oil so the less you use, the cleaner it'll stay. I spray the internal metal parts of mine with Remington dry lube to keep them rust free. If you'll do that, you'll only have to wipe down the outside periodically with an oily rag to stop corrosion.

Yours is a pre 1968. Some of the serial numbers were located on the side of the receiver cover and others were marked on the underside of the barrel forward of the stock.

You can determine the date of manufacture from the letter code stamped on the barrel.
Here's a web site where you can find that information along with some history of the rifles and an exploded parts drawing to help you with disassembly and assembly should you decide to.


Check it out. I think you'll find it's quite interesting and a wealth of information.

Hope that helps,


PS: Which model do you have?

I got 3 of these guns... WONDERFUL little rifles...I once totally dissasembled one of mine... (the first one, YEARS ago, before the internet, and you guys wealth of info)

I am happy to report that it IS still functioning... (bolt and hammer removal ain't too bad, when you figure out the tricks)

as for production dates... dunno... Harley Nolden (on this forum) might be able to help)

the ONE I have that has a serial # on it has it stamped on the bottom of the barrel, just ahead of the forend...

also, I have a "Kasnar" Brazilian copy of the Nylon 66... (OBVIOUSLY made with the same machines and whatnot, as ALL parts seem to be interchangable with the real thing...

You guys can get production dates from the link I posted earlier. They list all the mfg codes ever used.

Thanks for all the help everyone. The 66 is now clean, and re-assembled.

Bottom Gun, Thanks for the link. There is a wealth of info on the nylon guns there (confirmed date- Oct. 1964). As for mine, its a standard Nylon 66 - brown/white diamond. It is in excellent condition having been in a safe for most of its life. In no way does it look as old as it is.

Now, I hope no one recommends that I put it up and never shoot it again.:D

Hemicuda, will we see ya on Woodward this year?:cool:

Glad that info was helpful to you.

Shoot the heck out of it and enjoy it. You'll be surprised at its accuracy.
I have a couple of the Apache black ones and I love them.

Make sure you wipe down the exterior after handling it. That blued steel seems to rust rather easily.

Gordon- go to NYLONRIFLES.COM dedicated to Nylon 66- has excellent easy to do video on assembly and disassembly. All very simple- the caveat everyone is talking about is the trigger assembly. Lots of little flat springs. This you leave alone.

Wow, do I ever regret selling mine during grad school (so I could eat).

It was my first real rifle (beyond pellet gun). Loved it.

Heck no, but I do recommend that you sell it to me. :D

I don't recommend putting it up forever. I do recommend not trying to take it apart to clean it unless you are handy with tools and have a detailed set of instructions.

I'm sure you helped the OP a great deal.........if he's still alive.

This thread is over six years old:rolleyes:
