I have an older 24" SS Criterion barrel on one of my ARs. It's not chrome-lined, but I had it nitrided. It's very accurate and handles heavy bullets well.

Now if you have a 1/2 MOA barrel, and you put down 1 MOA groups, you know it was either you or if you feel like it was a good shot, likely the ammo. Your buying confidence in a way with a premium barrel.

My own personal experience. I chased my tail for a year or so wondering why I wasn't getting better groups after shooting my .308 for two years. Shot different loads, bullets, powders, etc. I kept thinking it was me doing something wrong. Well one range day I was so frustrated with my .308 bolt gun I took my AR out for shooting groups. My $600 home build with a $150 barrel and I put down 3/4" or better groups at 100 yards. I realized right there, it wasn't me, it was the gun. Saved my money, bought a barrel (happens to be a Krueger lol) took it to Randall. First day out with it, 1/2 MOA groups. I can do it all day long now.
Came back and read this, makes a lot of sense. Thanks for not putting it in the ďIf you donít buy barrel brand XXX youíre bad and should feel badĒ phrasing.

So I did buy a Criterion barrel because hey, why not? Might as well give it a shot! Worse comes to worse Iíll buy a Douglass if it doesnít work out.

Well-it didnít work out. My AR Performance barrel outshoots it pretty easily. My post on Arfcom-

ďI just ran a few strings of fire through my 18 inch hybrid CL barrel after breaking it in last weekend (not that the break in took long at all).
L.C. and Wolf Gold brass, CCI#41, H4895/8208XBR, 77gr Nosler CC, btol 1.861 via Hornady comparator tool.

Aero precision upper trued via Pac. Tool and gauge tool. Larue 12inch handguard and Syrac adjustable gas block. Barrel bedded into receiver with blue locktite. Nightforce 2.5-10x24 for glass.
Larue MBT trigger.
Shot from prone with bipod and rear bag.

First things first, very overgassed. My gas block is about half way closed to get reliable function from Wolf Gold .223, M855, and Black Hills 77gr OTM 5.56. I expected this as itís an 18 inch rifle gas so the gas port has to be large. No biggie.

Best group was barely under an inch, and they were my fouling rounds. .938 inch with WG brass. These all had inconsistent neck tension or other abnormality so I used them as sighters/fowlers.

Best group with 4895 was 1.10, average 1.51 across 7 groups.

Best 8208 group was 1.115, average of 1.46 over 7 groups.

With L.C. M855 (green tip) grouped 3.222

So overall Iím kinda disappointed. My AR Performance barrel groups much, much better with these same loads (.733 with WG brass and 23.3gr H4895). I wasnít expecting 1/2 MOA performance to rival Douglass or krieger, but itís not quite the MOA barrel I was expecting.

Just wanted to post my experience with it as there was little posted when I tried researching them.

Think Iíll finally pull the trigger on that CLE Douglass SPR barrelĒ

So there it is! It could very well be something in the build that went wrong but a tear down of the upper showed nothing obviously amiss.

Groups were kind of all over the place. No vertical stringing for the most part, and no horizontal stringing-just all over. I thought my scope was loose but the mount (Larue spr-s) was tight, scope nice and snug.

The quick check to confirm that the scope is good is to move it over to another known accurate gun and shoot a couple groups.
If the other gun shoots as expected, the optic is usually fine.

I took it from my AR Performance upper that has shot very well, so the only thing I could think of was the interface between mount and upper, but that was plenty tight. I will double check it next weekend though.

Also going to try some of the Hornady 75ís and some 77 SMK, but if itís not shooting the Nosler well I doubt itíll do better with the SMK and Iíve not read much good about the 75 grain Hornady.

Maybe being a (fairly) lightweight barrel with 1/8 itíd do better with 69 grain pills?

Hey itís a fun experiment right? Lol!

Iíll keep trying different things with it while waiting on a Douglass, but 23.5 H4895 and 23.4-8 8208XBR under a 77 grain bullet seems so universally good, and runs good in my other scoped AR, that I have trouble believing itís an ammo issue.

Only issue I can think of with my ammo is uneven neck tension as Iím using the standard RCBS FL sizing die. Iím going to get a Redding S FL sizing die with neck bushings to try and remedy that, but I canít imagine it would be that big an issue at 100 yards.

Next weekend Iím going to run the same rounds but with a very light crimp and see what happens.

Itís quite common for skinny barrels to just not shoot groups as consistently as thicker barrels.
The thinner a barrel, the more selective it will be in what it likes.
You might find it shoots a 69gr or 52gr smk lights out.
It wonít be because the bullets lighter though.
It will just be what the barrel likes.

You were supposing that I was making my decisions based entirely on price which is not true. I never questioned that a Douglass/krieger would shoot better, that goes without saying.

“Randall your posts are usually pretty on point but you need to adjust windage here. I’m all about buying a CLE Krieger barrel but if I can get a barrel that shoots almost as well, with an exponentially longer barrel life, I’m going to buy it.”

As you see barrel life was and remains my biggest concern.

Every time I shoot that Criterion barrel it puts a fresh smile on my face.

Best "add-on" I ever did to that ^JD machine^ made rifle. Another benefit is the chrome lining makes cleaning very easy. It's got a polished finish the other chrome lined barrels do not have, it looks different too.

I'm running an 18" match grade 308 Criterion from Fulton and haven't been that impressed. The best it can do is 1.5 MOA.

Is it chrome lined like the OP's barrel?

I never visited that shop. I waited too long, even though they were only about a half mile from my house. I guess some of the guys were regulars at the craft brewer two doors down, Bitter Brothers. I'm giving BB a plug BTW. Nice little tasting room with an interesting selection. Good people running it.

I have non-chrome, SS and the Criterion. The Criterion chrome lined beats all my non-chrome and SS barrels here. No, I don't have a $500+ SS barrel, just the mid level stuff as I'm a mid level shooter on a mid level budget.

Criterion floats my mid level boat just fine. YMMV.

1 sample is just 1 sample.
The OP has the opposite results which are also just 1 sample.

True. I don't have enough samples to make any pattern up. I also have a DD 14.5" that is quite good, way better than the 16" Daniel Defense barrel I replaced with the Criterion.

Could be a Monday vs Friday barrel or a broken clock is right twice a day scenerio, but that Criterion is a real shooter, at least for me. At only $249, it's was a worthy gamble for me that paid off.

Anyone want my DD 16"?
