The value of these videos cannot be overstated. Thanks for all you do, Chad!

that is definitely the color of fresh rust, the iron hydroxide means it is still reacting so a good clean of that surface layer was the perfect fix. the hardcore navy people can read rust better than me but that is one thing that stuck with me when i had a conversation with some experienced seamen

Holy crap I did not expect that barrel to be that clean from cleaning that that is some thorough work. Seems like that rust remover works pretty well too.

Compared to my R700 barrel, this barrel looks amazing. I bought the R700 used, and it still shoots 0.8 MOA at 800 yards. Im always amazed at how well a gun will shoot even with "issues" inside a barrel. We've been taught that a barrel has to be perfect for a rifle to be accurate and that's simply not true. All depends on twist rate, jump off the lands, bullet selection, powder, primer, and 20 other things that havent got a thing to do with the barrel perfection. Great video! Thank you for sharing all this wonderful info and experience with us. I am quite jealous of all the gunsmithing tools you own though. Even though I am an amateur gunsmith, I still feel I need all the best tools.

Back in the 1980's, when surplus 762x39 had corrosive primers, water cleaning my AK was the standard....but I spent several minutes with my air compressor drying it. Then sprayed it with RemOil, or Tri-Flow. Dot 3 Brake Fluid will break down bore rust. I saved an old Marlin Goose Gun by putting rubber cork in the muzzle, and filled the bore with brake fluid, and let stand in the corner a year and a half. Rust swabbed out.

An important thing to know about Evapo-Rust is that the parts should be COMPLETELY submerged. If not, you will have etching at the air/fluid interface.

I bought some of this product because of your previous video. This stuff is great for many purposes around the house too.

Chad is my hero and deserves all the exposure.

I always liked running an oil soaked mop through my barrels after cleaning. Something I picked up from my dad years ago. Especially if going into storage. Just don't go crazy. A patch to clear out excess is a good idea.

If you "REALLY" want to clean an AR platform down to bare metal and cleaner than it's ever been just use boiling water. Take the rifle apart and submerge in boiling water. Using coat hangers to create hooks to hang the parts on we would submerge the rifle parts in a metal trash can with a submerging heater to boil the water. A raging vigorous boil is best. When the parts come out of the boiling water they are so hot they dry themselves in just a few moments. Then we dipped all the parts in CLP and wiped them down. Easy peasy. It's amazing what boiling hot water will clean.

At least the corrosion wasn't real deep into the bore, but whoever didn't at least run a patch with some oil on it before shipping needs to have their knuckles cracked with a ruler as a reminder to not do stupid things.

Nice clean up👍 Really like these videos!

Thank you for your time making video's.

Very impressive .... Love this channel.

Wow! That is amazing. Great save on the barrel. Thank you for the great content. Always love your videos. Great teachers create great minds. You mu friend are a great teacher. Be safe.

Wow! What a difference; I did not expect it would work that well.

If you use heavy duty gloves and boiling water it A. Opens up the pours in the metal more getting more gunk out and B. It's hot enough to evaporate cuz the metal is so hot. You still oil it when done.

Cleaned my HK with a garden hose after a sandy excercise. I snaked it to remove the water but borecam still showed some drops. It rusted a little but I shot it clean.

Evaporust will remove bluing ! So just fyi on other guns

Wow, that was some gnarly rust!

Wow I would have thought that barrel couldn't be saved. Amazing

I picked up some Evaporust today and tried out on some T wrenchs, WOW its good stuff so far. I will be able to reblack them wiht a black oxide kit I got and they will look new.

WOW...great info!

I’ve learned so much from this channel!!

Its midnight and I have to get up early to beat rush for reloading supplies!! So I am so mad at you for this addictive content you are forcing me to watch!! BTW my PSA 300BLK pistol will arrive at my FFL this week. Hope it shoots as well as my Wilson Combat? Who knows

So I bought wipeout and accelerator about 4 months ago. The crap that came out of each weapon after sitting for 12hrs was amazing. I'll never use anything else again.

Great information

If you ever shot black powder you know all about cleaning guns with water!! The water causes LOTS less corrosion than the black powder does.

@School of the American Rifle This is probably a non-issue overly nit picky thing, but if you were trying to build the best barrel possible, would you try to drill the gas port directly through a land or a groove so it flow gas more evenly? I know thats not typically considered, but if you had a blank and could clock the gas port to be specifically where you want it, would that be advantageous, even if only a small amount?

Clr works great too

I am a huge fan of Wipeout also, no smells and that is win for the wife and I.

With all due respect, this does not look like rust to me. This looks like gunk on top of the surface of the inside of the bore. The bore also looks chrome-lined (which I would expect for a high-quality AR barrel) which should prevent rusting.

Excellent

Good stuff

Thanks for the video!! I would like to see a video a video comparison with a similar barrel that had 30 rounds fired through it to blow out the corrosion Thanks again you do really great work I've learned a ton

What is it about brass cleaning brushes that you don't like? That's what we used alot during basic training in the Army. Not being a jerk, just asking.

Going to have to try that Evaporust on a couple of my guns. Looks like very good stuff. Thanks and great job onthat bore.

When I was in the military I had a armorer who would soak his parts in diesel to get rid of carbon.

Cool to hear somebody else say you can clean a gun with water. I've used soap and water many a times to clean a gun without issue. An old Cuban guy taught me that you could and just told me to make sure and gently heat it for a short time to drive out any moisture to prevent rust and then lube it. So even now I still wash them in hot soapy water and rinse with hot water and then sometimes chuck them in the oven on low heat (the ones that I can fit in there) minus the plastic stuff. Never had any rust issues at all. Still will use solvents once in awhile but prefer the hot water as it's cheaper that way.

Great video!!! Any recommendation for a bore scope similar to yours for rifle length or for 24” for an M1?

My flintlock barrel isn’t looking great so I think I’m going to try this trick on that barrel

What would be a good gun oil for lubrication and rust prevention?

Was that a chrome-lined barrel?

Since this needs to be soaked for 12 hours, how would you recommend some very light rust in a model 70? I’ve tried nylon brush, bore tech eliminator, and slip 2000 oil.

Hey Chad is there anything you recommend doing in between the evaporust and the wipe out for cleaner?

If water was so good at cleaning barrels they'd sell it in bottles!😂😂😂

Will this work on a nitrated barrel?

Thanks for the knowledge, and the paranoia

How long should we leave the ammonium hydroxide to work before start doing no good to barrel?. Thank you and have a good weekend.

@InstructorChad was the FN barrel chrome-lined?

Never used that product, looks like it works really good. I have never tried this unless it was a stainless anything, clr does a great job, you can get it at the grocery store and I do use it to remove carbon out of all my barrels. Any feedback you got is welcomed and really appreciated! Thanks for the info have a good weekend!

Rubbing alcohol works well for dehydration.

Wow that evaporust works wonders.

Gunk caburator cleaner would be good for the carbon removal.

Hope a few folks can maximize the life spans of their barrels thanks to this info. Great topic & nice work! 👍 *(Anyone who 👎 this video is a douchebag! 👈😉)

I thought chrome lining prevents corrosion very well. All this just from some water?

What happens if you didn't try to remove the rust and just shot it as is?

What do you use for a bore scope? What would you recommend getting for a bore scope , just for an average guys for his own rifles?

How did the evaporust not eat away at the outside finish ?? 🤔 as evaporust will remove all finishes as well I’ve seen. Maybe I’m wrong and missed something lol

After boiling end of barrel in water to defeat Rocksett I could see that happening if you forget to protect with your choice of product.

I clean my muzzle loaders with soap and water. I never have had any problems.

I only clean black powder with water, in the bathtub

That rust did not happen overnight, that took quite a while.

damn man it takes some unbelievable level of abuse to do that to any barrel but especially an FN barrel, wow, if you let an FM barrel get that bad you don’t deserve to own firearms

Wow.

I would have thought that the chrome lining would have protected it.

I use ballistol to clean + the secret (sriracha) sauce, I don't think any of my barrels have ever been oil free, lol!

Looks like a urgi upper, but with an FN barrel. Interesting…

If you got rush after you used water spray down with WD-40

I thought chrome isn’t supposed to corrode?

That Evaporust is great stuff. It will even eat clean any galvanized parts. (frame rest on lanterns, whoops)

At this point if he shot the rifle a little he'd probably clear out the rest of some of the corrosion

Kinda surprised at how rough the finish is on chamber ream is for a 300 dollar barrel

That 4 prong tho

Would boiling the barrel in water cleaned it as well? Maybe you could try it with the second barrel.

Big difference!

Perhaps I missed it, but was this a chrome lined barrel?

YOU DON'T SAY HOW YOU FLUSHED OUT THE EVAPO RUST

Wonder how a non chrome lined barrel would've faired.

Why not use a brass brush? Chrome lining?

Another great Video.

Damn from night to day huh, was this chrome lined or no? Great video nonetheless

Why you don’t clean your firearms with water.

A FNC...... that's a crime in it's self...🤨

I think Ballistol would work well for this

outstanding......

Wow

🇺🇸 Awesome to see.

This kind of throws a monkey wrench in the argument for those that say chrome lined barrels are far superior to melonite barrels, huh?

Was this barrel chrome lined? Whe. You said it was FN I figured it was one of their chrome lined ones.

what borescope camera are you using? I also have a hawkeye borescope but I find their accessories prices way out of line with the quality they give you. FYI if you have the normal hawkeye flashlight (minimag light source) you can get a Maglite 226-Lumen LED Flashlight IP2PLPH and use the same top (its equivalent to their "LED" light). big upgrade small price.

Blaaawwww... nasty.

Woot woot, first one here

It needed some soratcha sauce

Hmm...10.3 with FN CHF and 4 prong SF FH ....
