It is a ADM Recon-S 30 MM that I currently have. Just exploring options other than QD. Debating Nightforce Unimount, they offer 3 sizes, unsure which height to choose .
I have a Bobro QD Mount on one of my AR's & like it a lot, locks up nice & solid, I definitely would not use anything with vertical split rings, these IMO are a pain in the ass & worthless, if you want to use rings I would go with Seekins.
If you don't want QD, take a look at JP Rifles' Flat-Top Scope Mounts: https://www.jprifles.com/1.6.3.6.php. They are high quality, sturdy, lightweight, and nicely priced. I use Aadmount on my AR-10 and MPA on my precision rifle, but I use the JPs exclusively on my two SBRs and 14.5" 5.56. I think you will be very pleased with them.
