AAC 51t adapter issue

Post by jcrjr65 » Tue Oct 19, 2021 7:38 pm

Running a 7.62 on a 300 BLK pistol AR platform I bought last year, using the 51T brake. Yeah, i got a little wobble in it, no big deal. Have used this same can on a couple of different bolt actions without a problem. Ran about 10 rounds through it yesterday for the first time on the AR pistol and was practically giddy about how well it performed. Took it inside to switch it on to one of the bolt guns, and when I stood the can up on its end, i noticed some material that fell out on to the bench. Turns out, not only was it a little carbon, there was some copper pieces as well. Looking in the can as best I could without a scope, I can see where some of the baffles have been damaged slightly. Looks more like wear than actual damage. No sign of any impact at the muzzle of the can. Nothing during the shot indicated a problem. Havent even put sights on this rig cuz i was basically just shooting it to see how the sound reduction would be, which is awesome. So, decided to paper these rounds without the can like I should have done in the first place, and it was perfect. Ran the can on a bolt gun using a different and already installed 51t and it papered perfect. Figured it must be the threading on the upper itself. Came across an extra 51t and thought I would replace the adapter I have been using on the AR pistol and give it another try. Switched it out, loaded a couple of rounds and it ran perfect! Truthfully, I cannot recall whether the apparent faulty adapter had been installed and used or not, I just hadnt paid that close attention. So, I will send the can back with the adapter and let AAC take a look at it and see what they say, but it appears to be a problem with the 51t. Not posting to knock AAC in any way, just venting a little practical knowledge for someone else to take advantage of. #1-Paper all rounds before mounting can. #2-Paper using can to potentially spot a problem not indicated otherwise. There was nothing indicating a problem, but I bet I would have noticed the wild POI. #3-Just writing all of this down gave me better understanding of what transpired. Not a big fan of keeping journals, but this experience would have been a good entry. If I find out something wonky from AAC, will post what they tell me.

Is ACC operating at the moment? I thought they stopped doing business, and was just wondering if you have info that they are operating at any capacity at the moment.

If not, I am wondering if any other company might be able to service that suppressor. I've heard of others doing it on other forums, but I cannot remember the name of the company that would do that. Others here might be able to chime in with more info.

Uh, well, thansk for that. I see now there has been a spinoff of their ownership but they are indeed operating in some capacity. Pardon my ignorance but I suppose this is what happens when you go off grid for a while. Will advise.
