View Full Version : Thoughts on rust?
So one of my fairly new builds has an issue with the outside of the barrel rusting. I went and shot all 7 of my AR's a couple weeks ago and the barrel wasn't like this, pulled them out today and this stuck out pretty bad.
None of my other rifles have any rust on them and these haven't been in any rain. I store all my rifles in the same safe.
I'm not really worried about it, I'm sure after I remove the handguard that it will all clean right off but I wondering if this is a coating flaw. Build was completed a few months ago.
Anyone ever seen this before on a new barrel?

That is definitely excessive. Especially since you have other ARs as a control. Is it phosphate or QPC?
I've had ARs out in the pouring rain that didn't get a spec of rust. Something is wrong.
I agree that something's not right with that barrel.

I have never had any rust issues on my ARs. Any good quality barrel should not have this issue. How are your weapons stored? Climate controlled area/safe?

Mind if I ask the maker? Hopefully they warranty it.
Thoughts on rust? Im against it!
Somethings up, any possibility of galvonic corrossion?
Could also be a poor/incomplete coating
This rifle and all of my other AR's are all stored in the same safe in our spare room closet.
I took all my rifles to go shoot over the holidays with my Father-in-law, heading out shooting this weekend so I pulled them all out today and saw this.
The finish is QPQ nitride.
I have an email going to the rep of the company to check on this, I wasn't sure if this was normal with some types of coatings so I wanted to get opinions here.

Is it just under the handguard? Is that the one FIL shot?
Reason I ask is I had a buddy with some kind of rust causing skin issue. I showed him my firearms once and every single one he touched rusted where he touched it. This even included my bright stainless steel Colt Python!
I have no idea what was up with him, but that was the last time he ever touched another firearm of mine!
Just wondering if FIL has same issue and he had his paws wrapped around the handguard and caused it.

I've never had a barrel rust like that before, especially a QPQ nitrided steel.
Hope they replace it because something is wrong with the finish or how they processed it.
That's some beautiful rust. Prettier than most I have seen. The patina is gorgeous. I'd probably pull the hand guard off and clear coat the barrel if it were mine. I guess I have a gay eye for things like this.
That might be QPQ, but it doesn't look like QPQ done quite right....
I've had this happen to me on a couple of nitride barrels when there was high humidity for extended periods of time. Underneath the handguards I couldn't keep them oiled frequently enough. Also happened inside the bores. Since then I have painted the barrels on the outside underneath the handguards and have oiled the bores more frequently. QPQ is not impervious to moisture and not exceptionally impervious to corrosion in my experience.
Possibility is that not all of the "white layer" was removed and that could be the cause of the rust.
If you take the guard off and it doesn't take much to remove the rust and you see no pitting, even minor, under where the rust spots are, clean the hell out of the entire thing, not just these visible rust spots, then oil it, reassemble, and find a way to reduce the humidity in your safe.
If, on the other hand, it does have pitting under the rust and has clearly compromised the nitride into the base material of the barrel, contact the manufacturer asap because that would mean a very incorrectly done nitride job, possibly done over pre-existing rust that is now pushing to the surface and blooming out.
I could see humidity causing this, but it's the middle of winter and not that humid here in NC right now. The room we store the safe in stays about 72 and the day we went shooting it was 67 outside.
Come summer time it's going to be real humid all the time, I don't want to have to remove my handguard all the time because my new barrel is prone to rust quickly.
I'll see what the company says and then decide if I what to keep it or go another route. I bought this barrel during a group buy on another forum so it was a mass order.

Pretty sure i know who the manufacturer is based off of your Sig Line and it being a group buy. They should take care of you, but interested in the reasoning as to why it is rusting like that. I haven't seen any other reports of that happening
If that is happening on the outside of the barrel, what is happening on the INSIDE?

From the group buy there were a couple of members that reported their barrels arriving with rust on them during shipping. I didn't think anything of it because mine was perfect when it arrived, and I'm sure one swipe of an oiled rag will remove every bit of this rust easily.
I just don't want to have to keep removing the handguard to do it on a barrel that shouldn't be rusting so quickly.
Hopefully I'll here back this week, and it's not going to stop me from shooting it this weekend.
I just don't want to get rid of the rust in case they want it sent back to see for themselves.

Exactamundo! If it were unique to the outside, I'd rattle can it. But that's not possible based on my basic knowledge of QPQ.

No rust on the inside but this is a newer barrel that I'm still breaking in so it's had a patch ran through it pretty often.
And since it's so new I'd hate to have to rattle can it to fix an early rust issue.

Damn, that's not supposed to happen. Please let us know what the manufacturer says.

I have a friend like that. I was playing with Sentry Solutions dry film stuff at the time and everything he touched rusted inside of 2 weeks. Thought it was no good then it dawned on me I had degreased and applied the stuff in August so I was sweaty. Took some of the parts and wiped them with Sentry then alternated soaking them in salt water and drying with a hair dryer before setting them aside for several months to find zero rust.
Barrel looks dry as a bone
Every time you are done with a range session, you need to oil the exterior of your barrel through the holes in the handguard with a bottle of oil. I mean so it is visibly glossy wet. The more the better.
Storing guns in a closet is one of the worst possible places due to the stagnant air in a closet.
Also this barrel is 416R stainless.

Perhaps this was screwed up?

Looking at pattern and consistency, it appears they botched the rinse and oil dip steps after the final salt bath.

I've got a Rem 700 SPS that does that. Take it out in the rain and nothing happens, put it in the gunsafe and in 24 hours it has a fine patina on the barrel.
Well, the gentleman that arranged the group buy offered to refund my money and shipping. He still hasn't heard back from the company but he was willing to deal with it. Real stand up guy! I removed the barrel today and will ship it back in the morning.
So today I ordered the barrel I should have went with in the first place, it's just going to be a long wait..........

Probably a smart move.

Did you try contacting Faxon directly? Glad the group buy person took care of you! What did you end up ordering?

No I didn't, since I didn't buy directly from Faxon. The guy that organized the group buy did contact them and is still waiting on a responce.
I ended up ordering a Bartlein 6.5 Grendel barrel from precision firearms, they say 10-12 weeks so we'll see how long I'll be without my Grendel. Plenty of other AR's to shoot until then!
well crap
another barrel mfg to cross off???

That was certainly nice of him.

All companies make mistakes.
One of the first major issues I have heard from Faxon. Nonetheless, there can be a lemon in every batch, no company is excusable of that. It's the Lemon to Reliable Ratio that has to be taken into account.
For example:
People are harder on PSA as, while the majority of their customers never have an issue, a larger population of people get products that don't have as much strict Quality Control Standards. Higher percentage of warranty replacements than say... BCM. Or Colt.
All companies make mistakes, it's how they fix them and if they continue to happen regularly or not.
As of today, I would still buy from Faxon.
I have a Faxon Gunner barrel I am quite happy with, and a Black River Tactical barrel that I am certain Faxon made, so I am not a hater.
I find it ironic that Faxon provides this guidance on their website: "Stainless steel can be easily nitrided, but it is very difficult to add chrome to stainless steel. Nitride*significantly*increases the barrel life and corrosion resistance of “stainless” (which for barrel stainless steel is not rust-proof)."

Please don't mistake this for a Faxon hating thread, the barrel shot very well and wasn't even one of their match barrels. These were a special order for a "group buy" built custom by request for our Grendel group, the barrel I had was not one you could just buy from their website.
I almost ordered one of their match barrels after removing this one, but decided that since it was an expensive build that I wanted to try an expensive barrel with known accuracy.

Can't go wrong with a Bartlein! I agree with other statements that Faxon is good to go. I have heard a lot of good things about them, but mistakes happen. The gunner is still on my buy list for sure

Properly performed QPQ Nitride can’t do that. A 200 hour salt spray test result looks different. So, a process must have been botched. I have 4 Faxon barrels under my roof now and have installed many more than that on patrol carbines that live in the trunks of cop cars in Florida. Never seen that on any of them.
I’m confident in saying that’s a fluke. Also, cross shopping Bartlein and Faxon puzzles me; like saying I want a Camry or an S-Class, lol.

Can't tell if serious or joking.
I have a 15 year old Armalite barrel, phosphate coated, that has spent half its life in various cases and has never been oiled that I can remember, and has no sign of any rust.
Maybe I'm just lucky?
I do take care of my blued (bolt-action) barrels with either Boeshield, Corrosion-X, or lately Flitz gun wax. The latter also makes QPQ nitrided barrels look nicer and feel slicker, but they shouldn't need it for corrosion protection.
You're in Nebraska so I doubt you get more salt air exposure than I do.
I'm not telling people to be total slobs, but with phosphate I think oiling once a year should be enough (unless baking the barrel from heat AND exposing it to salt air), and for properly nitrided steel nothing at all should be needed.

I kind of had a camry engine in an S-class body, I think the barrel was the least expensive part in my entire Noveske build? I picked the barrel first by joining a group buy, didn't realize how much I was going to spend on the rest of that particular build until I tallied up the final bill.
I think the barrel shot fine, but after being offered for a full refund I didn't want to stick another "budget"barrel in my 6.5 Grendel.

That makes more sense.

I'm not a fan of exotic snake oils. That said Brownells Rust Preventative #2 has solved any and all rust problems for me. No rust, not one pit, freckle, 'tinge of red stuff' at all in the ten years I've used it. Just a thought.
