I looked at the Rugged MICRO 30 last night. I read up on it, too. It is user serviceable, modular, full auto rated, and just over 11oz in the short configuration. I like that model but I do not own one.
I own Banish and Silencer CO suppressors. I have no problems with accuracy with any of my cans. I have done some research and I see that TBAC has a reputation for their performance when added to a long range or precision rifle.
I would take some things into consideration before buying. As a general rule, the longer and heavier the can ~ the quieter your report will be. Barrel length, barrel thickness, and caliber will also be variables in how loud/quiet your report will be.
The 6x6.8 is a .243 bullet in a 6.8 case. I have heard the 6.8 caliber, supersonic, and suppressed in a 16" barrel. It was still loud enough to need hearing protection.
Here are some questions you can ask yourself:
What is the primary purpose for using this can? (fun, hunting, long range hunting, etc.)
Do I want direct thread or QD? (I like QD mounts but both have their pros/cons)
Is weight a factor? (Hiking around a 2lb can is not ideal but will be quieter than lighter cans)
Is overall length a factor? (are you hiking, sitting in a blind, shooting off of a bench?)
Is accuracy a factor? (Banish and TBAC have a good reputations in this area)
Take some time to jot down what you want and then go with the questions to finalize your choice.
