Who's got one? What are the pro's and con's? Do you like the way it attaches? Is there a noticable difference between wet and dry? I have been doing some research and this can looks like the best for the AR15. All advice appreciated. Thanks.

| I dont know if I would say "best" but I have one and it is a very nice product. Very well made, and the sound is super. Ops Inc and Surefire also make top notch products, and if I were choosing a can, I would take a good look at all three. Do you think you can find a place to hear, shoot them yourself? I know that might be tough. I have not had any problems with it coming loose, and I honestly dont recall reading anyone having a problem with it coming loose. My next can is either Ops Inc or Surefire..... hard choice, because both are top notch. I personally rule GemTech out for a personal can because we have them at work, and I want to have different toys for my personal stuff....lol. They are also a top notch can. If you are getting ready to plop down cash, it might be good to call the dealer, or company and ask some questions. |

I've got one its a great sounding can and built like a tank. the mount is simple so not alot to go wrong with it. A friend just got 1 and the new ones are lighter and have a lower tone to them the one i have is 2yrs old. I like the ops can don't have one but seem like a good option. the surefire is very cool looking and the mount is nice but i've heard they don't sound as good and there customer service sounds H&K like. Once you go down this path you won't be able to come back you'll want them for everything. Cans make shooting so much more fun!!! chris |

My M4-2000 is a well-built, easy to mount/dismount, quiet can. It does change the POI, but the change is repeatable-- however, I solve the problem by always shooting the AR with the M4-2000 mounted. I do NOT leave the can on the gun when it is in the safe. If you choose the AAC M4-2000 I believe you will be happy with the results. Dave Brown |
Has anybody else had this issue? Do you mean that the metal on the flash hider gets burred/chewed up, or only that the finish on the fh gets dull/worn? This concerns me becuase metal getting chewed up means poor tolerances/design. Anybody else had this issue with thier M4-2000? I read the write up in the winter 2003 issue of Special Weapons and they covered it in great detail. The author said that he believed it was one of the best if not the best. Here is the link: www.advanced-armament.com/articles/pdf/m42003.pdf |
It is a close fit and when the suppressor is removed from the FH it rubs on the surface. It has not burred or chewed up mine at all -- I just have a few "rub" marks on the FH. Dave Brown |

Mine shoots loose. The retaining wire rests on the top of one of the teeth (instead of in the trough). After a few shots, the can will spin counter clockwise a few degrees. This is just enough to allow the suppressor exit hole to wobble up and down about 1/32 of an inch (maybe less). Luckly, I haven't had an end cap strike. Going to grab some teflon tape to see if that helps keep it tight.  __________________________________________________________ Forgot to show my street creds

I have shot a M42K quiet a bit. they are a well built can. They are heavy and the mount does get scuffed up from attaching and detaching. My personal one is at AAC right now being rebuilt. It was sticking on the mount after a few rounds. I hope the upgrade gets the problem solved. I would dedicate it to one of your AR's if possible so the POI shift will not be a factor I like the phantom mount they came out with the best, i think that was a good move for AAC |
|
I've got an M4-2000 and have shot it quite a lot. I've never had the can stick on a Phantom or A1 mount, but it does stick to the SOPMOD. Reason is that the SOPMOD mount is designed to be a slighlt bit larger than the Phantom to accomodate the KAC can as well as the M4-2000. A little ScotchBrite scrubbing will fix that issue for the most part though. Never had the can shoot loose. Shoot it frequenty on full-auto. Caught the can on fire - twice - and finally had the can refinished by AAC. Check out my buddy's friend dumping some rounds full-auto through my M4. Notice her recoil management (and cute pink shorts  ). Can you count the four pieces of brass in the air? Mark |

The retaining wire is not timed correctly on mine either. We need instruction how to effect this. I have not given it much attention lately as where I had been shooting with it no longer exists. BTW, Still love this can and mount. Mine does not come loose quickly and is easy to keep up with though I am sure there is a remedy. |
|
I have only shot mine one time. I checked the ring on mine, and see that it is not timed correctly either. You can see th v shape bend resting on top of a ridge on the flash hider mount. It lets the can spin freely backwards a tad bit until it locks fully into a ridge. I Am sure KevinAAC will be along shortly to provide an answer. Maybe replacement springs? My next can is OPS INC or Surefire... |
Same with mine... thuoght about bending but thats prob a bad idea. I posted a message on the silencer testing board, because I do not believe AAC is here much. Perhaps the spring wire can just be replaced? |
Teflon Tape  I'll have a review on how effective it works this Monday. While I'm at it, I'm gonna pick up some small o-rings at Home Depot. My Pilot spins loose as well. Come to think of it, I also had a problem the the mount on my Striker II suppressor. Just haven't had a whole lota luck with these mounts.

I love mine it was my first NFA purchase I did get it used and cheap though have friends that have KAC and a Gemtech the KAC seems a touch quieter to my ear but the AAC mount is worlds better than the other 2 IMO been happy with my purchase and think it is every bit as nice as the other 2 EDIT Drr IM a moron and can't spel gudd |

The M4-2000 is designed to always be within 1/2 click of the tapered shoulder. This is normal. The best M4 silencer before it was the KAC M4-QD and the M4-2000 has between 1/3 and 1/8 as much POI shift as the KAC can. The distance between the valleys on the flash hider were selected with this in mind. It is fine as you have it. All of them are always within 1/2 click and that is how they are made. |
Thanks for taking the time to copy and paste the reply that silvers wrote on silencertests.com on my thread there.. |
I apologize, I was not trying to insult you. I just did not originally believe that we would need two separate answers for the same question that were posted to two different boards. Again, my mistake, I apologize. There are tolerances built into everything about the M4-2000 mount, all with good reason. Some of these tolerances allow for the silencer to unscrew approx. 1/2 turn before misalignment occurs. It will still deliver the best accuracy and zero shift available in a fast-attach mounting system. Let me know if you have any other questions, or you can post to Silencertests.com where many other knowledgeable people are still allowed to post. |
Gotcha... as long as she is Good to Go, I am happy. I dont think it would be possible for it to actually loosen while shooting, because the wire detent seems very sturdy. Nice product. I am very happy with it. Does anyone know if the SOPMOD flash mount and the standard Phantom pfash mount are interchangable, so I could pick up one of the SOPMOD mounts and use my M42K with both? |
Yes, the M42k is usable on both mounts with no modification. However, as I posted earlier, you will probably have a tight fit for a while with the SOPMOD mount. |
You could say that. I have a pretty funny video of me and another guy trying to get the dang thing off after only 300 rounds. I'll try bookhounds scotchbright method. |
