    Default Cleaning an HK MP5SD Suppressor.

    I am a Class 3 SOT and my buddy gave me a Pre Sample MP5SD suppressor. He gave it to me because its blast chamber was all carbon caked up. The suppressor didn't cost me anything, so what the hell. I'm going to get this baby cleaned even if it takes me a year. I started off using a thin, curved blade tip, long shank wood chisel. Going through the breech end I kept tapping away at the carbon until I got tired. I then took an AR15/M15 chamber brush with stainless bristle bristles. I screwed it on to a five inch cleaning rod shaft and went to town with a power drill. Again more crap was removed, but I snapped off two cleaning brush shafts and quit. It looks like about 20% of the blast chamber is cleaned up. What a bitch.

    I'm going to make a pint of Ed's Red, place a rubber stopper in the suppressor's breech hole, fill 'er up with Ed's Red and leave the suppressor soak for a week or so. I really want to unscrew the rear of the suppressor to get to the baffles and continue with the carbon caked blast chamber.

    One of the guys here (maybe HKCHUCK?) uses an ingenious method of affixing a fish tank bubbler through a cork and lets it bubble itself clean.


    That's the best I've seen.

    Does anyone know if the blast chamber is screwed in via left hand threads or right hand threads? I may never get that far, but I have a potential need to know.

    Cool

    Not sure how well this setup would work on a suppressor so caked up as the one you have.
    But for cleaning a lightly used one this way is pretty slick.

    Is there a particular builder you've used before? Perhaps they have taken one apart.

    Won't the armorer's manual have this info? I'd check that if you haven't yet.

    That's what I would do as long as the entire construction is at least stainless steel. If there are any aluminum parts then it's a no go. Hence why I never purchase aluminum suppressors. Which that's really only as issue with .22 but still. Must be stainless steel or better or I don't touch them. If we're talking rifle cans then I'm shooting for a stellite core. Good luck OP!

    I spoke with Mike Woodward this morning and he has never disassembled one. These real HK suppressors are made of aluminum and harsh chemicals are a no-go. Prior to giving me this suppressor, my buddy tried to clean it with an ultrasonic cleaner. All that did was pit the aluminum exterior. The carbon crud was untouched. So, for all you guys out there considering using an ultrasonic cleaner, don't be dumbasses and place any aluminum in there. You are now officially warned.

    Getting back to my challenge; Mike Woodward said a buddy of his cleaned a carboned up one on a lathe. It turned out perfectly. I don't have a lathe, but I'm going to keep going with a chamber brush and then try a small diameter cylinder hone. Mike did point out that cleaning out the blast chamber is all that needs to be done. The baffles never get too much carbon anyway and it's best to just leave them alone. He told me to just attack the blast chamber and all will be fine.

    I couldn't find anything in Armorer's Manual pertaining to an SD's suppressor.
