We've discussed this elsewhere, but I'll break the ice on it in this thread.
So far, I haven't seen enough of a example spread to say whether it has, or doesn't have, any effect.

I appreciate the bump, but me thinks not many people on here have experience with a cryo treated rifle barrel.
I've never had one done, but I shoot with a bunch of people that spends lots of money on rifles and there isn't a one that is cyro'd.
Most if your good barrel makers will heat treat (read north of 1k degrees) and spec out the steel for the blanks they get. None of the top barrel makers (barlein, kreiger,brux, etc) use it. Kreiger used to but stopped. Its been around for 20+ years and I've yet to see hard data that says it works or makes cleaning easier.

Funny, I was going to ask if cryo was still a thing. And then I just saw of video by Iraqveteran888 on the Valkryie with a cryo'd barrel on Youtube.
They were claiming 80 ft/sec faster.
I had barrels cryo'd back in the late 80's or early 90's. The gunsmiths claimed that stainless barrels machined easier and lasted longer. I never had one cryo'd and one not to do an A - B comparison. I don't know if they really lasted longer or not.

I'm hopeful that E.Shell will put his 2 cents in on this, due to his experience with long range shooting.

80fps is a good pickup, but barrel life, consistency, accuracy, etc... are my primary concern with this. The AR10 DMR is going to be built one time and I would rather have what will give me all the advantages I can get, but no flash in the pan kind of stuff. I remember the moly coated bullets and how the shooting community was divided on those. I would rather not fall into the same trap.
Cryo is exactly like moly coated bullets IMO.
Put it to you this way, if it helped even a little bit, you'd be seeing all the benchrest/fclass guys using it/them. Again just my $.02.
Lots of this sport is a head game, if you BELIEVE it helps, you will be more confident and possibly shoot better. Is that worth $100, that's up to you haha.
I'd also like to hear what Ed has to say.

Yea, I see your point and I believe you are right on this. I appreciate the input.

Basic metallurgy and thermodynamics suggest it it bunk.
You don't speed up phase changes, chemical reactions or dislocation movement (stress relief) by lowering the temperature of a solid. In metals, these processes are already glacially slow at room temperature.

I'm falling in this camp. My guess is that it's a way for adding a service that increases the cost of the item...not much else.
That said, I have one Remington 700 with a cryo barrel. It shoots just as well, but no better than my other custom Remington 700...and also my off the shelf Remington 700P.

Plenty of Mini-14 owners have the barrels cryoed to get better and more consistent accuracy out of their Minis. The pencil barrels on the original Mini-14s tended to wander after heating up. Thicker barrels, which I'm guessing your AR-10 has, don't really need this.

'zactly. Cryo is more of a snake oil sale for the shooting community. Normalizing I can see have more of an effect.
Another poster talked of the mental side. I believe he's right.

The M1A that I bought from a very good friend, had been cryo'd before I got it.
Kreiger Hvy Match barrel.
More 'stuff' done to this gorgeous rifle than I could tell you.
FWIW, clean-up is a LOT faster, quicker, easier on this barrel, than any other that I've ever owned.
Accuracy????
Think what you want, but, this rifle will hold 1" groups at 200 yards, as long as you can hold 'er steady.
Snake oil????? I don't know.
Am I convinced it works?????? It works on THIS rifle!
These are the people that cryo'd the M1A that I have.

I have seen a marked improvement on thinner barrels that had cyro treatment, BUT to be fair the treatment was always paired with other work. Trigger, blueprinting, bedding and so forth. I can't opine on ease of cleaning because I think cleaning often is bunk. My opinion is biased.
Heavier contour barrels, no observed improvement.

Excellent. I was considering a SPR barrel for it from X-Caliber spec'ed the way I wanted for rifling, chamber, threading, etc... Would an SPR barrel fall into the thin barrel category, based on your observations?

It was a thought to go that route, but I realized that making tiny groups at 1k isn't important when you are going after varmint. They aren't going to care what group size you are making when they are meeting their maker.

It may help on that contour D.A.
I would just buy a Kreiger AR10 with a M110 Profile. That bad boy will shoot.
