I'm wanting to put this scope on my Thompson Encore Rife (Tasco Titan Scope, 8-40x56mm, mil-dot reticle, 30mm tube, black matte finish) and I have a Quick release base...but I do not know what rings I need since my leupould 3-9x50 almosts touches the barrel....dones anyone know if there are QR rings high enough to use with the TITAN scope,if so a model number of the rings?
