OK Gentlemen, please help me ID this .308 WIN barrel…trying to figure out who made it.

The story on it is that it’s a take-off from a rifle built on a Remington 700 short action that a coworker bought for the action, stock and some other things on the rifle. He’s going to rebarrel the rifle in a different caliber. He gave it to me because he said he didn’t have a use for it.

It’s a 24” barrel and it’s pretty obvious that it’s not a Remington factory barrel. Definitely carbon steel. The only marking on it is a small stamped ”308 WIN”, there’s nothing else I can find on it.  It’s also obviously a pretty heavy profile. It had a considerable amount of copper fouling which I was able to clean out without any trouble.

I don’t have any gauges to check the muzzle or throat erosion but doing the old “bullet test” on the muzzle ala checking AK kit muzzles from a few years back, it appears to have a lot of life left in it.

The only real concern I have are threads on the chamber end. I’ve included some pictures for your review…please help me on this as I might like to use it on a beater bolt gun build.

My coworker is a competitive shooter and doesn’t use .308. He generally prefers 6.5CM and doesn’t use .308 in competition that I’m aware of.

I’m going to keep as a .308 and probably use it to build a “beater” rifle for myself or give it to my son. I just want to keep it as inexpensive as possible.

I can probably get a R700 action for a reduced cost through work and would probably go with a KRG Bravo chassis.

Yeah, just found out that it’s a Remington SPS barrel. I would have never guessed that but, then again, I haven’t really been around bolt guns for quite a while.

If I can get it to shoot .75 MOA, I’ll call it good.

6-groove rifling.  You might be able to tell cut or button rifling from the surface finish at the muzzle end (usually minimal erosion on that end).  If you can see traces of super small "grooves" in the grooves of the rifling, we're talking nearly microscopic scale here... then it's likely cut-rifled, and that may narrow it down a little bit.  HS-Precision makes cut-rifled 6-grove barrels.  Others will, too, but typically you see 4-groove (brux, Krieger, etc.) or 5R (Bartlein).  If it looks like a mirror, it might be button rifled and it's anyone's guess.  Wilson, Douglas, Benchmark, Mcgowen, etc... Most of them honestly are 6-groove.

I have 3 SPS rifles and that barrel doesn't have the same crown nor the same contour.
That barrel looks to have a straight contour.
If it is an M24 wouldn't the caliber be 7.62 and not 308?
Is the rifling 5R?

Your barrel is an aftermarket based on the .308 markings.

Standard practice to reuse a worn barrel is to cut 1" from the muzzle and recrown. Barrel bore diameters open up a little bit at the muzzle after repeated firing.

The barrel threads are then cut off and new ones are cut to fit your receiver and a new chamber is reamed to achieve proper headspace.

This basically gives you like new rifling ahead of your new chamber because the old erosion has been machined away.

That barrel is significantly heavier than any factory Remington 700, outside of their 40-X competition rifles. You have plenty of material to work with.

Taking the time to make sure the bore is running perfectly true on the lathe before removing any metal will pay dividends.
