A few people have issues with 18T but most don't. I have an 18T can with many rounds through it and it never backs off. It's unfortunate that some people have problems but I also think it's silly when those couple people act like the 18T was total rubbish or that there's some sort of AAC conspiracy going on. The 18T was better than just about everything else on the market when it first came out.
I bought two of them - and both back off all the mounts I've tried and turn a .75 MOA rifle into a 3-4 MOA rifle at best. I figure I have about $2k into these between the cost of the cans, mounts, and fees. I'm at a lost as what to do now so they will probably end up on some .22LR or some 5.56 blaster. I've thought about drilling/tapping the mount and adding some setscrews, not sure what else I can do to keep it from loosening up.
As a last resort I wonder if AAC can cut off the fast attach and wield a Cyclone threaded end on it for you? THAT would fix it for sure. Granted is not waht you wanted or paid for. The thread on works for me. Even if it does loosen up 1/4 a turn is going to have less wobble than 1/4 a turn on the SD since the pitch is less aggressive. With Teflon tape it will NOT come loose anyway.
My Cyclone-K has KIS technology (keep it simple)
Seems the SD mount works for a the majority of the people but some people it does not work for. So the design must have some "vulnerabilities." What are they, and why the SD mounting system works on most but not on others is the mystery.
Is it the spring tension and temper?.. Nope.. as many have replaced just the spring to no avail. So just what IS it?
Just like a older S&W N frame... a very few have a harmonic vulnerability and when things are just right the combination of variables can cause the locking to skip and the frame to rotate around the cylinder.
IMHO the SD mount is doing something similar. The barrel whip, weight of the rifle, and tolerances in the mount and silencer are just "right" to allow the catch to bounce off the valley and to jump to the next tooth. Fire repeat.
It is possible that swapping the mount and spring (not just the spring) may change the variables enough so that the silencer will not do it any more. If not than try adding weight to your stock might help to "fix" it.
I would attack the variables. Easiest first... and see if by changing them you can stop the mount from backing off. Even the "play" between the mount and the silencer may be contributing to the problem.. I would even try changing the mount from "flash hider" to Muzzle brake if available in the 18T as it might help to change the harmonics even more..
I.D. what is different between yours that is failing and those that are working.. Then trying to change the variables ... That's is how I would approach it if AAC won't replace them.. I am sure they will try to help if you work with them. I do not know if AAC changed the design of the SD somewhere during it's life that makes the silencer different from yours. Obviously the SD works for many. Just how do they make it work for you.....
Good luck. I hope you can find a fix.
