Gunsmithing At cleaning debate

[GhengisAhn175]

I'm at work with my peers and superiors and were sitting around cleaning weapons (m4 to be precise)

I suggested to get the carbon out easier , you can attach the bore brush to the cleaning rod, cleaning rod to a de Walt and use the de Walt to help clean the insides of the bolt carrier and star chamber. For star chamber can use
Bore
Brush end to break up carbon and then a sponge to clean it out.

My reasoning for this is:
Was how I was taught in my old unit
Bore brush on de Walt ain't gonna do shit to it compared to bullets going of with insane high flash points , pressure and a bullet traveling out at 2970 fps.

He freaked out saying it'll ruin the metal, take off bluing, etc

But isn't that what I use the brush for anyways? Obviously don't brush outer surface where you can wipe easily, just use the tool for inside bolt carrier and star chamber.

I'm sure he also believes that running a bore snake the opposite way will ruin the rifling.. As far I was taught bore snake isn't fast as a bullet going through


Anyhow anyone got their 2 cents?

The inside of your bolt carrier, where the bolt lives, is chrome lined and your brush will likely not harm the interior. If you are using good cleaning solutions and need to get it all cleaned out you should be fine.

Power tools have no business in gun cleaning.

There is no such part as a star chamber. It's called a barrel extension.

If you are using a jointed steel cleaning rod and no bore guide, you are tearing up the throat of your barrel/chamber badly. Screw together rods are for field, not garrison.

Carbon is not bad. Excessive carbon is bad. You can not get excessive carbon in the bolt carrier...it blows it out when fired. Buildup is on non critical surfaces.

More damage is done trying to scrape it off than from leaving it.

fastest way to get serious caked on carbon out of my ar's is brake cleaner (make sure not to get it in the trigger or you have to re-grease). i use a spray can after the gun have been run a long hot string or 2 or 50, ha ha.

in theory the brush should not take off any coatings but the brush is picking up crap along the way, maybe some sand etc. if you let that spin around it will scrap off coating. and as for the sectioned steel rod we all know, they are probably the biggest cause of barrels loosing accuracy. now on a shorty ar made for door kicking it wont mean a thing but add some distance and it will add up.

" to help clean the insides of the bolt carrier and star chamber"

in those 2 applications, it wont hurt anything.... just dont use it in the barrel at all...

that said, the star chamber should be cleanable with break cleaner and no brush...

Thanks for the info.

To address some things in case guys here aren't military , when 1sg says clean for inspection it means if you run a pinky through and get black it's unclean.

Second cannot use products that aren't approved through the military which includes certain solvents and cleaners.

Again the brush is not going inside the barrel, just enough to clear up the "star chamber".

The replies do help and does answer what I was looking for. Thanks fellas!

Barrett heavy bore cleaner is very good at cleaning carbon and it should be authorized, we used it on the brake on the Barrett.

Try that for the barrel extension. You can do similar with a pair of forceps and the head of a q tip...all from the medic.
