Remove the 4 screws from both rings. Place the scope in the ring halves and re-insert recoil key. Start all 4 screws on both rings and tighten bottom screws to 25 in/lb* max. Place rings onto the bases with the recoil keys in the slots. Push each ring towards the muzzle to seat the recoil key and tighten QD lever, thumb & forefinger tight. (there is no need to over tighten QD lever) Adjust eye relief and level the reticle. Once both are correct, tighten the top screws on both rings to 25 in/lb* max.
*After tightening, pull QD levers out to index them to the desired position.
