I have a 14.5" 1:7 chrome lined with a vortex mounted on it. Cmmg/DPMS. Couple of years old. About 2-3k rounds of wolf and XM193 through it.

One day it would not eject shells for anything. It became a single shot as i had to tap out every single shot. Also, the brass would have huge GOUGE marks across the side of it. craziest thing.

Anyway, I  took it to a gunsmith who removed the upper and took a look at the interior. He said the chrome lining in the chamber area was uneven, non existent in some places. He said the interior was borderline destroyed and unuseable.

Any possible way to fix this at all or are any of the part salvagable? Rechrome line it? polish it out or something??

Sounds crazy but it was a great rifle till way one it started jamming all to hell.

CMMG is good people I would contact them, I am sure if the damage is due to a defect in their product they will fix it.

+1 on contacting CMMG, they would probably just get you a new barrel but I cant speak for them.

I think you already got you best answer. CMMG has a huge presence here and I'm sure they will make this right if it turns out to be a deffect in their product.

CMMG is good people but I wouldn't be suprised if they don't feel responsible for damage you may have caused.

Thanks for the replies.

Tomorrow when i have time, I will send them an email and a link to this thread and just see what they have to say and if they can do anything.

If they would even give me a discounted replacement, i would be thrilled. If they said sorry too old, my feelings wont be hurt and i will have to salvage what parts i have from it.

Will post again shortly with an update, hopefully.

CMMG and others may not honor a warranty if you use Wolf, but the use of steel cased ammo won't damage a normal chrome lined barrel.

Well that would be sad since the 6k of wolf I have through my Bushmaster barrel hasn't managed to do any damage. I would think that a company that specializes in high end AR parts would at least demand that same level of endurance from their parts.

You guys need to get over the "Wolf is crap" syndrome, if it fucks up your rifle, or your rifle won't run it, then there is something wrong with your rifle.

sounds like that gunsmith just wants to sell you a new barrel.  I don't know your gunsmith, but i've talked to a few people calling themselves gunsmiths.  My dad once bought an FN-49 not knowing the caliber, because it was hellaciously cheap.   A local gunsmith told him he had an 8mm fn-49, upon closer inspection it was actually 30-06.   So, my point is that I don't trust the average corner gunstore "gunsmith" until i get to know them.  I personally don't know how you can look into a barrel with your eyeball and tell that the chrome lining in uneven.  

P.S.  the guys at CMMG are great!!!  I've been buying stuff from them since before they even had an ffl.  They have always had great customer service.

If your "gunsmith" didnt have a borescope to truly inspect the barrel and chamber you need to tell him to FOAD.

Sounds like BS to me.

One other thing, the wolf ammo is great, i guess, I don't use it in AR's,  i've heard about the laquer off the cases building up in the chambers of AR's and causing malfuntions.  If i'm wrong, someone correct me please.  I do know there was some concern about the laquer on the cases.  

What did the gouges look like?  Were they only on the rim of the case?  If so this means the case is sticking to the chamber.

As a matter of fact, I had a 14.5" dpms barrel that was chrome lined.  exact same barrel you have.  first range session, i had a case fail to extract.  I could only get it out with a cleaning rod.  It only happened one time.  After that it ran like a champ.  After a few months went by, I read a book about ar-15s, i can't remember the name.  It talked about this exact malfunction with car length gas systems.  Basically, in my case the bolt carrier was getting too much gas, too fast.  It forced the bc back so hard and fast, that it pulled the rim right off the case.  You know like when people get hit by trains, it pulls them right out of their shoes.  When the gas system got some fowling in it it ran awsome.

anyway, i'd get a second opinion on your barrel.

CMMG warns not to use wolf or other steel cased ammo.

In fact it will void the warrenty on their complete rifles.

But that said Jeff and John should still be able to work something out and get you up and running.


and as John puts it.

Its not the 2 or 3 thousand rounds of wolf its the one round.

Wolf IS cheap crap and almost every manufacturer warns against using it. If you like it so be it but the stuff IS made by commie Slavs who could give two fucks if your rifle blows up or peals its chrome lining.

If CMMG decides to warranty the barrel then that is big of them because they are well within the right to deny responsibility.

I've never understood the metallity of buying a $1000 rifle and running the cheapest shit through it.

It's not surprising when you think about the price difference. Consider the fact that one can buy another rifle for the cost of 3-4 cases of M193 spec ammo at curent prices.

Think about the number of people who buy a $30,000+ car or truck, but run regular gas because it's 10 cents cheaper. People are pissed about current gas prices, but imagine if the cost of gas to operate your car for one year would pay for another car.

I have the same barrel from CMMG, also run wolf, not a problem what so ever.

Sound to me, you got ahold of a bad one.

Because in all 4 of my rifles is works just fine, no problems that I can directly attribute to the ammo itself.

I've shot it in matches, and through 4 Carbine classes with the only issue being during a high round count class in 100 degree weather. On day one after about 700 rounds on the first day I had one malfunction. I dropped off the line and spayed a little lube in the action and it finished the day. Cleaned it that night and it ran the whole next day with zero problems.

The reason I say I can't directly blame Wolf for that Malf is that I believe I had run my B/BC group a little dry that day and after 700 rounds in the heat I burned off what was there, but then again, Wolf is a bit dirty, so who knows.

Meanwhile, I spent half what others paid for their ammo.

I have about 6k of XM193 and Win Q3131 here, but as long as Wolf keeps running and costing what it does I would be a fucking idiot to shoot anything else for plinking, classes, and matches.

I have a 5 day carbine class coming up the end of next month, I'm taking 4k of Wolf with me for the class. I'll be happy to give you guys a full report of what 4k of Wolf can do in 5 days.

Middle of the pack, but I'm a newb to rifle/shotgun competition. Still, even using an Eotec I got my hits on the long range stage with targets out to 300 yards. Any problems I have are more about me than the ammo.
