I have an AWC Turbodyne and it came with different thread mounts to use on smaller calibers. I'm going to mount that 5lb can on a .308 or 6.5 and test out the accuracy.
Lite weight doesn't necessarily mean better barrel harmonics.
A friend of mine is into precision shooting and his groups shrink when he has a large suppressor on, so much that I now have a Nomad L in jail.
I will put up with an extra 6oz for decibel, accuracy and durability performance.
