Ive ran these rings on multiple hunting platforms with a Maven rs1.2 and a Sig Tango6. I primarily use their QD's with my Tenmile and Accupoint 2.5-12.5, and my lever gun has the Accupoint 1-4 Green Triangle in QD as well (I love lever action thermal hunting). When torqued properly, mine held up. The weight difference was negligible between their QD's and the Mountain Techs, and have mounted & dismounted just fine. I am a huge Warne fan; however, I always avoid 'ultralight' and just stick with 'light to medium' depending on the scope and caliber. I don't have guns that get babied, nor do I have cheap scopes; trust Warne in all of them.
If you ever do have an issue, they legitimately have the best customer service I have seen for an accessory MFG. Just call them up, doesn't matter where or who you bought them from, and they will take care of you.
(These rings get removed daily on my lever brush gun when sun goes down coyote/hog hunting in FL, LA, and TX. Always return to zero if I do my part and don't rush. When I rush, the most they were off by was 1-1.5 moa when I only tightened the front fully and not the rear. Reset and back to a proper RTZ)
