Our high height Tactical Ring Mounts model #24112 would be a good fit.

No. Mounting hardware is sold separately.
Although the aiming points may be calibrated to .22LR by adjusting the zero distance and magnification, the yardages for the .17HMR calibration are etched into the reticle. Instead, we would recommend a general purpose reticle or one of our reticles calibrated specifically for .22LR high velocity, or .22LR sub-sonic.
