Ive owned a AAC M4-2000 for several years now, I rarely shoot anything 5.56mm unsuppressed now a days.

Yes I understand there is a suppressor sub section, it gets decent traffic there but wanted to get a broader opinion on this subject than the standard response.

Yes I also understand almost every rifle suppressor manufacturer says not to clean sealed rifle cans, as they supposedly self cleaning. Hmm sounds somewhat familiar to the Vietnam era thinking of when it came to ARs doesn't it?

In my experience from shooting mine quite a bit, some sort of cleaning will eventually be needed. I am 8K+++ down my can, which is a heavily conservative estimate, and it has significant carbon fouling.

I have noticed that switching between different adapters, such as a MB to a FH on separate hosts will knock a small amount free, but still there is significant fouling.

One thing to note, I didn't use a FH mount until this summer, doing so knocked a few large chunks free, and then I noticed I had a end cap strike. Not sure I can 100% blame the carbon breaking loose causing this, but having that rattle around inside a can cannot be good.

Ive tried a few different thing, I have soaked it in mineral spirits, carbon killer, CLP, with absolutely no results. I have tried copper and steel brushes, with no results. The only thing that has even began to remove the fouling is a flat head screw driver and a hammer(yea its in there that good).

So despite the standard response of, you don't need to clean your suppressor, what can I do here?

Update- I already whaled at it with a screw driver and hammer. Next step is to either dip it or drop it in the cleaning tank at the shop. Ill post pics with the after action results of which ever I go with.

       Have you asked the manufacturer what they suggest?



Maybe an ultrasonic bath in carbon killer solution?

I had in the past, before significant fouling appeared. They said no cleaning is necessary other than the mounts. I have emailed them these pics to see what they suggest, but no dice yet.

This.  I'd just contact AAC and see if they will take care of it.  Mers has been damned good about any customer service (I think he still there).

Free stater problems.



Isn't there a service life on suppressors? Will AAC "repair" it? Can they replace everything and keep the same serial # so you don't have to do all the NFA stuff?

I ran mine in a heated ultrasonic cleaner with castrol superclean in the purple bottle. It not only cleaned the carbon out, it also killed the finish on the can which I believe is air cured cerakote. The can is clean though and sounds like it dropped a few decibels in the process.

Dammit, GemTech recommended something to clean my suppressor but I can't remember what it is!  Basically you just fill the suppressor up, let it sit, then empty it out and allow it to dry.  I'll post the name this evening if I can find the thread.

Harbor Freight Sonic Cleaner might get the carbon out and be less damaging to the can.  Worth a try.

I would (and I'm not kidding here) boil it in a 15% caustic and water solution for an hour or so, and let it cool in the pot.

The crap should almost float out after that.  

Edit: if using caustic (or Super Purple works too, as sugested below) DO NOT use an aluminum pan.

The shop at work just got some new deal to clean corroded, dirty, greasy, oily heavy equipment parts.

Im not sure its ultra sonic, but it does heat, I need to drop mine in it for an hour and see what happens.

I think ultrasonic maybe the route I need, But I have heard its hard on welds? Anyone know if theres a truth to this?

The dip seems shady to me.

I have done it on leaded barrels before with no ill repercussions, but something like on a silencer makes me worrisome. The can is made out of stainless and some other hard as shit material so I believe it would be fine, but the dip would have to be an absolute last option for me

What about thermal shock.......like dry ice it -109F and then warm it up?  Or simply dry ice in the can with warm water and let the freeze, forming carbonic acid do an acid wash and the effervescence clean out the can?

I've used it several times on stainless baffles in my Element and Sparrow SS. I don't know how it would react with the Inconel blast baffle. I also don't know what other materials that can might be made of.

I have an M42K in 6.8, but I only have a couple of thousand rounds through mine.

Agreed, I have done it for a few barrels before. Its simply so nasty and a pain in the dick to dispose of in the right  way.

Im not against using this method, but want it to be a last ditch option. I have no doubt the can would be fine, but its the handling of the toxic material after I would rather not mess with

plug the end, pour in the dip into the core, let it sit in mason jar. when it's finished, invert the suppressor into the jar, shake out the fluid/gunk into the mason jar. screw on lid and keep it as the dumping jar for future cleaning or call your local recycling center to inquire about disposal of hazardous material

Don't get me wrong. This is definitely an option I am considering. I just want it to be a last ditch option.

But you are correct it wouldn't be hard to do, and exposing the unknown items would definitely be minimized if not eliminated by the process you described

Dip in simple green use a Spaghetti Tower, shake the hell out of it let sit for 4 hour. Wash the can out with water then dip it WD-40 in the tower again take out blow out with compressed air. Repeat as needed. Don't do with aluminum can.

Or use Ed's Red instead of the simple green

Ultrasonic with carbon killer.  It is going to have to soak for about a week or two...  

Personally, I would run it for a few hours, soak for a day, repeat...for a week or so.  

Carbon killer and similar products require a lot of soak time.  They are not fast acting at all.

I let it soak for a day, but wasn't in a ultra sonic. It didn't do anything for me just sitting inside there, but ultrasonic could be the game changer

Certainly an aspect to consider.  Do any manufacturers have advice when shooting in extreme environments?  I mean if you are up in the Arctic and blast a 30 rd mag on a cold can that would be a greater extreme.  No doubt the type of metals used are a factor, but I've just never seen even generalized info.  I shoot a lot of 22LR in my early version 45 Tirant.  I just freeze it and then blast some centerfire ammo in it.  It seems to be safe, but on a full power rifle I would be  hesitant.  I don't have terrible fouling, but then how much 22LR is a bad thing?

No. The dip is designed to remove lead buildup by chemically reacting into lead acetate. Lead isn't the problem in a centerfire rifle can.

I believe theres a mix of carbon, lead, and vaporized copper in the blast chamber. I bet the dip would do some serious work on that stuff.

When you get enough rounds down the can, lead can most definitely be an issue. Most 5.56mm rounds have the ass end exposed which is bare lead

AAC replied.

Plug kroil for atleast a few hours(I would be surprised if a day or two would even touch whats in there). Then try to attack it with a stainless brush, or use a screw driver and hammer like I have before. He says he doesn't believe much crud would make it past the blast chamber

I replied back asking about ultrasonic cleaners and the dip.

There is definitely a difference in rimfire and centerfire fouling....Rimfire has poorer ignition and more unburnt stuff, as well as more impurities.  It also doesn't generate nearly as much heat so there is less lead vapor, but certainly the possibility for more lead exposure at the borehole.  It seems like more Pb distribution in the can's core.  So regardless you have to be able to remove Pb.  I think Pb removal challenges are over hyped.  Lead solubility increases dramatically below a pH of 6, however if you have other non metallic constituents it minimizes the contact of acids/heated solutions with Pb or Cu.  This is why I believe frequent mild acid baths are important to keep a good metal removal rate and thermal shock is good to break up carbon fouling.  I'm still experimenting, but I haven't ruined my can yet

There is definitely a difference in rimfire and centerfire fouling....Rimfire has poorer ignition and more unburnt stuff, as well as more impurities.  It also doesn't generate nearly as much heat so there is less lead vapor, but certainly the possibility for more lead exposure at the borehole.  It seems like more Pb distribution in the can's core.  So regardless you have to be able to remove Pb.  I think Pb removal challenges are over hyped.  Lead solubility increases dramatically below a pH of 6, however if you have other non metallic constituents it minimizes the contact of acids/heated solutions with Pb or Cu.  This is why I believe frequent mild acid baths are important to keep a good metal removal rate and thermal shock is good to break up carbon fouling.  I'm still experimenting, but I haven't ruined my can yet

plug the exit and fill it full of the dip


No. The dip is designed to remove lead buildup by chemically reacting into lead acetate. Lead isn't the problem in a centerfire rifle can.


I believe theres a mix of carbon, lead, and vaporized copper in the blast chamber. I bet the dip would do some serious work on that stuff.

When you get enough rounds down the can, lead can most definitely be an issue. Most 5.56mm rounds have the ass end exposed which is bare lead

Id imagine its pretty hard to actually ruin a can. I mean I was sitting there whaling on mine with a hammer and a flat head screw driver the other night. Got a decent bit of the fouling out. But theres simply no way to go farther than the blast baffle with this method
