Quality 11mm rings

Hi Folks. Do any of you have a recommendation for quality 11mm scope rings. 
I often put adapters on my rifles and use Warne quick release rings. I really like them and they make quick scope changes easy. 

Same reason my CZ rifles use DIP Weaver conversion rails. 

Most of my problems with 11mm rings is quality and lack of quick release.
 
these have been Ebay for awhile and are just large unit that have been around for a long time

if you clamped them well enough they would have a greater contact area and then you can use your weaver-pinatinny rings

I have been meaning to buy some to put in my overfull ring and mount box, no that one is full my second ring and mount box

you could add a bubble level extra ring

and if you don't like the idea of buying off Ebay with a China seller don't be, I have hundreds of transactions with only a few problems

time to the west coast is 12 to 22 days

just an idea I know you said 11mm rings
