These didn’t work for what I needed. They are low height for a 1” tube. Quick detach. Uses 6 cap screws. Their description said it will work for weaver bases, but the slot on my weaver bases was too narrow. Works great on picatinny rails.

Here is the description from their website- Primary Arms Low 1-inch Tactical Rings place the center of your 1 inch tube scope 0.75 inches above your 1913 Picatinny rail or Weaver rail platform. Two rings are included, each held together by six Torx head screws. Constructed of high quality aluminum with a matte black anodized finish, these rings feature a lifetime warranty.
