Relatively compact - Vortex Razor Red Dot AR15 Riser Mount

If you are looking for a sturdy, well built and fairly compact QD riser this is the one. Easy to adjust and stays put once dialed in. I did not give it 5 stars because of the white lettering. Not sure what drives manufacturers to splatter white lettering on top of black mounts or other dark colored parts but its obnoxious. Ghost it out or utilize something much darker.
