After-Action Report: Criterion Barrels, Inc.

This is my after-action report for a recent experience with Criterion Barrels, Inc.

The short version of this report is: Exemplary customer service second to none, from a company that fully stands behind its product at all costs.

Here's the longer version of this report:

I ordered a Criterion match barrel from Jim and Northland Shooters Supply. The barrel arrived only a few days later, and I was testing loads that the same week. I followed a delicate break-in procedure, and the barrel shot same-hole groups at 100 yards and 1" groups at 330 yards. After a match approximately 400 rounds in, there was a thick layer of copper fouling visible down the muzzle. While troubleshooting this problem here in the forums, a Criterion rep named Josh reached out and offered to have the new barrel lapped again.

The barrel was sent back using a shipping label CBI provided, and when it arrived at their facility Criterion sent me an email detailing the work order. Around this same time I discovered the fouling was the result of bad advice in the form of three inches of Devcon under-barrel bedding. In spite of this, Criterion held true to their word and refinished my barrel. Days later I received another call from Criterion rep named Stephanie explaining the barrel was on its way back to me. An email followed soon after containing tracking information.

Once the refinished barrel arrived, I gave it a thorough inspection. Criterion re-lapped and re-crowned the barrel, but there was a small patch of tiny scratches on the lands visible from the muzzle. I contacted Criterion by email and attached photos illustrating my findings. Within minutes a call came with apologies, and an email with a return shipping label. Criterion reps remembered that I was planning to have a muzzle brake put on, and offered to do it for me if included with the return barrel. Josh painstakingly collected the details for a new barrel order, and explained the process. Within days, a completely unexpected personal apology letter and embroidered cap arrived from Criterion Barrels.

I sent the parts to CBI in late November, less than four weeks later I've got a brand new barrel with fitted and timed muzzle brake in my hands. Everything fit together and aligned perfectly, and I'm excited for the 2015 competitive season!

The customer service demonstrated by Josh at Criterion Barrels has been absolutely second to NONE. I have never in my whole entire life experienced customer service to this level of professionalism and courtesy; most especially not from anybody relating to the firearms industry. Lupold Optics is the only other industry-related company to go above and beyond, and even they don't come close. I'm already deciding what barrel to have them build next, because they've earned a life-long customer.

Thank you, Criterion Barrel. I hope that other companies learn from your example and strive to follow in your footsteps.

I was wondering about that too, Wayne. It's great that they stood behind their product, but if that's what they say caused the problem, we never would have gotten to the point where they took care of anything. I'd have laughed it off and hung up on them.
 
Yea i gotta hear this. I guess blame it on the first thing thats out of their control. "Yep! That was it! Now send it back and we'll fix it real quick."
 
Devcon may have supplied their aluminum-bearing epoxy, instead of their steel-bearing type. The dissimilar metals could have caused some kind of electrical activity in the chamber area, thus stripping copper molecules from bullets as they passed, and depositing them in the muzzle area.

A little sarcasm I think.
 
Yes, a little. But it was a very interesting story about the barrel, and great customer service, which is in short supply these days. I hope to hear more.

Criterion offered to refinish the barrel long before I discovered what was causing stringing and copper fouling. in fact, they reached out any post where I discussed the problem I was having.

The Devcon liquid steel created a 3-4" bedding mold around the under-barrel right after the recoil lug, and acted as a heatsink to retain heat while the rest of the barrel cooled. Once hot, this caused shots to begin stringing higher and higher, since the lower portion of the barrel was still heat expanded and the cooler upper portion contracted. The added heat right at the max pressure (Pmax) zone caused additional copper shedding, and increased bullet friction. In other words, don't ever bed the under-barrel of any rifle that will shoot at a pace fast enough to get hot. Hunting rifles typically shoot single-digit rounds, which is why you might occasionally see it used there. Bed the receiver, not the barrel on rapid-rate competition rifles.

Once I removed the under barrel bedding the vertical stringing and copper fouling went away but I still decided to take them up on refinishing the barrel.

Bedding under the barrel for a couple inches at the breach makes it copper foul clean to the muzzle. Amazing.

As pointed out, repeatedly, this applies to barrels that get hot from a sustained high rate of fire. A barrel block on a slow-fire benchrest rifle won't have the same effect, because the barrel doesn't get hot. High pressure and heat already cause quite a bit of fouling, but add a hot spot to the barrel and it gets worse. Why is this so hard for you to understand? :confused:
 
Unless I misread the post, I don't think that the devcon story came from Criterion. I have used a Criterion barrel (pre-fit) for a Savage in 6mmBR and it is excellent in every way. Criterion laps their barrels and they represent an excellent value at a very reasonable price. Good shooting...James Mock
 
rattle battle match? only thing I can think of that would have something akin to sustained rapid fire, in combination with pushing the upper limits of a reloading the cartridge.
