want to remove and put back red dot sight without re zeroing; is this possible

[Dino1]

Another thing to remember is you have to retorque your mount to the same torque setting each time you remove your optic. This is why the quick disconnect mounts work well if you do not turn the nut, and only use the lever. Make sure you put it in the same location, and push it as far forward as it will go before clamping it down. A dab of fingernail polish on the rail will tell you were to remount it. I use the UTG Leapers quick disconnect mounts and have never had a problem with it rezeroing after it has been removed. I love that Bug Buster, I believe it is the best value for the money out their for an optic for the rifles.
