AAC 5.56 Cans

I thought I may have been sold on my first suppressor with 2 AAC products the 51t or 91t ratchet mounts. Upon more research, it appears some people are having issues with the teeth wearing out and the button release pin failing and falling out. Any recommendations? I assume these teeth wearing out are used error related because I've had a ratchet tool ive used for 15-20 years that I have no issues with. If I have a bit more patience the RMS2 Hopaii seems like the best new product out there.
I have the M4-2000 and the 7.62-SD versions.
I have yet to have an issue with either of the complications you've mentioned going on at least 6 years now.

Interesting. Sounds like the complaints may have been purchased lemons and or user errors.


I hold the release button down when tightening, then snug it down with just a single click.
I have one of the 556-SD cans and it did exactly that the first time I shot it. Had it repaired and zero trouble of any kind after that. YMMV.
