| What maintenence is there on the MP5 with the integrated suppressor? I have heard with some suppressors that they are only good for "x" number of rounds and then they need to be replaced or something I don't know I am clueless on the suppressor business. Can anyone help? |

I've got one as well. My suppressor has several thousand rounds thru it and counting without any degradation in performance. As long as they are properly maintained and cared for, long life is not an issue. The SD variant does get dirtier and need more cleaning than the standard MP5, but I wouldn't trade it for the world. (In truth I had to buy one of each) I soak my suppressor in WD40 every 500 rounds or so and blow it dry with compressed air. No worries... :) |

Hey, TDunn! :-) I was gonna chime in about your -SD... didn't know you were here in the flesh. I *will* add, for the benefit of Maverick and others, that the -SD barrel is ported near the breech end (to bleed off velocity and render standard-velocity rounds subsonic), which deposits carbon and crap directly onto the bolt group, much like the AR-15's direct gas system. This causes much more fouling than would be found on a standard MP-5 with a muzzle can (I'm guessing). Compounding the problem when *I* was present, was that there were about a dozen folks on location to shoot the gun, and we were running it almost entirely on full-auto as fast as mags could be loaded and the gun handed off. The thing got so hot, the paint bubbled on the receiver (sorry)! The MP-5SD is not intended to be shot in this manner, IMHO, and as a result we had to tear it down and clean it every 300 rounds or so. When relatively clean, it ran like a champ! And in all those hundreds of rounds, we never did clean the suppressor... No loss of sound reduction was noticed. Me using and abusing TDunn's SD:  |

That was a tough day. The old girl got passed around quite a bit. :) When shooting in a controlled fashion (2-4 rd bursts), I have had several 800 round days without malfunction and without cleaning. The day mentioned above was a true torture test. As Mark noted, any suppressor efficiency loss was NOT noticable. The best thing about the SD is you can buy the standard supersonic ammo and still be VERY quiet. |
With my SD, I take it apart after each trip and soak it with some break free. I scrub the threads on the suppresor and the barrel. my gun is original German dealer sample and it already had some rounds through it before i took possession. it used to be one of the SWAT guns from Seattle PD. Since owning the gun, I had more then 2000 rounds shot out of it. I don't notice any degradation on the peformance but I am sure it has degraded somewaht since new. next to the KAS stainless steel MP5SD it is a bit louder.

 Mine is also a Factory German sample, though it now sports the "F" A3 stock and 3-burst trigger pack. I became concerned about the all aluminum suppressor and did some research. I was told that the life of the factory suppressor was only about 10,000 rds. HK told me they wouldn't refurb my can, and recommend that I replace it with the KAC Navy SD can so that is what I got (factory can pictured). I like the KAC can, it's steel and more quiet (though expensive) and can be used wet. (I advise in not using water in an aluminum can BTW) The KAC can looks a little ugly though, and thinner making it look out of place. At any rate, because the factory can is aluminum, don't use solvents that eat aluminum like Hoppes. You shouldn't really have to clean the can, though it does fill up with residue and unburnt powder. Cleaning it helps eliminate first round pop. I never had a problem removing it or attaching it, but the ports get dirty and can make it difficult. Get the HK port brush, it attaches to the back of the suppressor, then you slide it down and spin it to brush the barrel ports. Do this regularly and it will keep it easy to pull off and on. Perhaps I don't have a problem because while it is hot, I take it off to cool it faster before stowing it. |
Do you have a pic of it with the KAC can? Thanks. |
| Well, in my case, I simply bought a new can (the KAC unit) so yeah, I had to pay another $200 tax. I still have the original suppressor, I just don't shoot it much. Now if you are asking about a can that gets rebuilt or destroyed and replaced by the manufacturer (on purpose) then no, you don't have to pay again. |
