I have had the Stoeger M3K and I now have the gun it copied. The Benelli M2. (Also an M4 and a Nova Speed) No issues with the M2, plenty of "tuning" and "break in" with the Stoeger. Much of which helped reduce my problems with the Stoeger were Benelli parts.
The ONLY thing that would make the TNA VR-66 tempting is that I have a Canadian company, whom I like, that I can call up when I have problems. Might be worth speaking to them first about support before buying.
You may not mind it being fussy on ammo or the bolt failing to go into battery or the failures to extract. But all of my issues with a Turkish M2 clone happened on the clock. 3Gun and IPSC.
I've run almost exclusively target load through my VR-66, lots of cheap stuff and never had it not go into battery or fail to extract in over 1000 rounds. TNA service has been really good.
