Inexpensive qd mount that functions well, not rock solid but definitely sturdy enough for range time - AIM Sports Inc 1 in. QD Cantilever Scope Mount

The qd levers use a pulling mechanism to unlock and lock. The front and rear levers will "run into" each other when released. Adjustments are good and available in small increments, this is something even expensive qd scope mounts sometimes lack so big plus there. I dislike the torx screw choice, as I have to carry around an extra wrench instead of just using allen head screws. The finish is terrible, flaked in some places and feels rougher to the touch than standard anodizing found on receivers and hand guards. Can't speak for the metal itself, haven't used it much outside of mounting it but it feels/looks like 6061 aluminum. All in all, this thing definitely feels snug on the rail and the screws work to clamp down the scope. If you don't mind it looking worn from the poor finish (kind of feels like paint) and just want an inexpensive qd scope mount that works, this will do it.

I have not gotten the opportunity to test return to zero.
