Home Forums Hunting & Shooting Gunsmithing Remington Model 721

That's true and toward the end of 721 and 722 production (1958), there were 721's, 722's without the barrel boss sometimes called "transition models" that used the same barrel contour and sights of the early 700's. I have a 722 transition model in 222 magnum with the later barrel.

I don't think that any of the 722s in 243 or 308 had barrel bosses, I think that they had 22" barrels that were exactly the same as the 725s.

I have a late production 721 30/06 with a 22" barrel with no boss. It was almost mint when I bought it for a song a few years ago so I'm certain it's the original barrel and stock.

It would be interesting to know how that transition went, aside from very randomly! I have had an early 700 in 30-06 with the boss and have seen a couple others.

I have several other Remington with production codes that cannot match the model or cartridge or some other cataloged detail and it sure makes them look disorganized.

There is always going to be a certain amount of error in a production environment, probably less than 1%. I don't recall John Lacy mentioning 700s with barrel bosses.

I'd be interested to hear the specifics of your Remingtons with assembly codes that are out of sync with cataloged details.

As you know, it is pretty easy to swap barrels on 700 series rifles, often without having to set the barrels back to get correct timing, so putting a newer barrel on an older action isn't all that uncommon an event.

But only because it belonged to Mike Walker.

I am in the tedious stages of transferring my records to electrons... as I come to them I will post them and perhaps start a thread. I will try to remember to let you know when I come to them.

Thinking about it, none of the half-dozen or so 700 variations I have swapped factory barrels on ended up even close to timed...

I find that about 50% of the Remington 700 series barrel swaps that I've done, in excess of 60, that timed and headspaced without any work. Many folks report much higher rates than mine, some claim 100%.

I saw a Remington 700 for sale that the seller claimed was a rare lunchbox special straight out of Ilion, when it was actually a parts gun that I'd put together for I guy who I used to hunt with. Without authentic documentation/provenance, a story is just a story, even if it is a really good story.

I have a couple of Remington 721's for sale in my online shop:

remington-model-721-3006

I killed my first elk with a .270 chambered 721. Solid rifles that are easy to upgrade to ADL, if desired.

Speaking of 721s, I just picked a v nice 721 in 300 HH. Ser # 55xxU. Barrel is 26 inches long, I believe shes stainless under factory blueing. Barrel stamped UU. Any idea of date of manufacture? 1948? This rifle has the slickest action I ever worked!!

Assembly code "UU" is 1949.

I wouldn't expect a serial number in that age range to have an alpha character in it.

Thanks!

I would not expect to find a SS barrels under the bluing...
