Refining a Full Auto MP5SD at work and the carbon build up on the barrel under the suppressor is thick. Any suggestions to removal other than jack hammer??

I got tubing that just fit over the barrel and cut teeth in it to cut the carbon. Works great.

That's a great idea!! This sucker is caked up something nasty

The attachment isn't working for me. Is this not something that the barrel port scrubber can take off? Is it a separate issue? I'll have my MP5SD any damn day now and want to make sure I have everything I need to clean it.

I coat the inside of my suppressors with Frog Lube. It makes for easy cleaning. Perhaps you could try it on the problem surface after you get it cleaned up.

I did the same for the ID of the suppressor. I got tubes that fit in tubes to clean into the different interior diameters from the spacers to get access to the baffles.

Probably the first time that the suppressor was cleaned since its birthday. It was at least 25% full or more.

Interesting idea. My SD can is sealed so I may atleast try this stuff on the exterior of the barrel and give mine a few sprays fwiw

I will get a can that ASAP. Monday I will start chiseling away at the barrel!!!

Remember a couple of years ago when a thread as this was posted and how many people would immediately post "Use Fire Clean!"

I started using Anti-Spatter spray and it does help. No matter what you use or do, SD's need to be cleaned often to avoid the build up of carbon.

Precisely why I got rid of mine!
There's no denying its one of, if not the, coolest looking MP5 variants, but damn its a PITA to keep clean. Hell, I even think about picking up another one from time to time... That's how strong the pull is!
However, the MK-9K on a standard MP5 with Special K is fun to shoot as well and just as quiet in my experience... Plus your pushing a 147gr projectile instead of a whimpy 115gr at subsonic levels.

Its quite the dilemma though!

Lol if you think the SD experience is all about db levels

Umm... Pretty sure I said just the opposite.

This suppressor is so caked up. Will a bath in ultrasonic cleaner help break this up??

^^^^I second this ^^^^
Small needle scaler works well also...have had to use this in the can expansion chamber also when someone literally never cleaned their can.

 

[Gorgosaurus]

...careful with the scaler in the can though, remember it's aluminum.

I don't think ultrasonic cleaners and aluminum mix well.

Right, cavitational attack is a real concern for soft metals. Additionally, the typical fluids used in ultrasonic cleaners can damage aluminum. You can run it with just warm water, and there are aluminum-safe fluids...just shop carefully. It's no guarantee as the compositions of aluminum vary, but you can put some aluminum scraps in there to test it. If the aluminum is being compromised you will most often see a "tail" or "stream" emanating from the part.

Working increasingly course grades of blast media may be appropriate for hillbilly's project.
