I went the QD route so one suppressor can do it all. Sure fire, YHM, and Silencerco/SWR make rock solid QD mounts.
As for the other comment about Huntertown arms making a SS rimfire can for $300, that is not the kestrel which is $400 and offers much better performance. At that price point, it is easy to pick the SWR Spectre II. It is the same design as the kestrel at $360.
Prepare for the long weight. I'm 6 months in to mine for a .30 cal can. 6-10 months to go so I might get it next summer. It is a trust so if they kick current forms back when the rules change, it could be years.
