I really didn't expect them to hold, but it was the only ring set I had on hand to mount this Nightforce 8-32x BR scope with. Torqued to 20+ inch lbs, the 30mm Signatures wouldn't hold the scope in place. After about 20 rounds it had moved to the point where the zoom ring area was bumping against the ring insert. I wish my Badger ring order would hurry up and get here!!!
