I have a AAC Cyclone and a SAS 30 cal can... can't beat the SAS for the money. Work great on my 308 but you don't need high tech cut edge to make a whisper quiet.
The chances of my going for an F1 can are rising quite a bit now. I probably can beat an SAS for the money. I may not get as light. But DNR should be as good or better.
I'm looking into a reflex design. Great for a large expansion chamber behind the muzzle. But it will be rather specific to the barrel. So the SAS will win in being able to be moved from rifle to rifle.
