I heard that the 762 SDN-6 had this issue with older mounts but I am using a Brakeout 2.0 I noticed the other day after firing only about 20-30 rounds it loosened from the first tooth.
I have a couple 51T mounts that my suppressors WILL lock up tight on and the rest will always fall back to the one tooth less position, some of the mounts are new others are older and they are FS and MB. It has always been the accepted way the 51T locks up, I'm not exactly happy but I've never had one of my suppressors back off anymore when I make sure it's locked.The 51T system was not designed to lock up with tension like the 90T system does. I don't have a single mount on my guns or a single silencer that mounts up to any of my mounts that locks up with tension like the 90T. You should always tighten it down and then back it off until the latch is sitting in the valley of the teeth.
Last I heard that was due to a bad batch of heat treating, My 762-SD has just as good of teeth now as it did new and it's been run on and off an ungodly amount of times.I do know the Teeth Wear out on the latch, when attaching hold latch down so teeth do not rub teeth on Muzzle Device..
It's the first time I used it, virgin mount, virgin can (maybe that's a poor choose of words). So is it o.k. to blast away when it's backed off on that tooth? It has evident play left and right when it unlocks from that first notch/tooth.
From the AAC rep "You should always tighten it down and then back it off until the latch is sitting in the valley of the teeth."It's the first time I used it, virgin mount, virgin can (maybe that's a poor choose of words).

In the works.You can keep shooting and not clean the mount at all - over time enough carbon will build up and give you a tighter lock up -
You can go to your LGS or where you got your suppressor and try several mounts till you get the lock up you want -
You can polish (note I say polish) the beveled edge in front of the teeth on the mount till you get that +1 tooth lock up -
Buyers remorse, NO, it will just reside on my 300 BO. I did not know how bad things were over at AAC or I never would have bought from there.. 18T problems, Fix 51T, 51T problems, fix 90T were they doing through testing at that time, not when a company is in Turmoil.. Waited 10 or 11 months for that set of stamps.. Yeah, I would NOT have bought AAC if I had known of internal problems..Other companies lock up tighter then, we'll let's just say that have NO movement.We get it, you purchased the last generation design right before the new generation came out. It's called buyer's remorse.
