Killer Instinct Ripper 415 Scope Adjustment

To adjust the scope on your Killer Instinct Ripper 415 crossbow, follow these general steps:

Use the appropriate adjustment turrets on the scope to make these adjustments. Turn the windage turret to adjust left or right, and turn the elevation turret to adjust up or down. Refer to the scope’s manual for specific instructions on how to make these adjustments.
  • Sighting In: Start by sighting in your crossbow at a closer range, such as 20 yards. Shoot a group of arrows and adjust the windage and elevation as needed to bring the point of impact to the desired target. Repeat this process at different distances to fine-tune your scope’s adjustments.
  • Reticle Illumination: If your scope has illuminated reticles, adjust the brightness level according to your preference and lighting conditions. Refer to the scope’s manual for instructions on adjusting the reticle illumination.
  • Test and Fine-Tune: Once you have made the initial adjustments, test your crossbow at various distances to ensure that the point of impact aligns with the reticle. Make further adjustments as necessary until you achieve accurate and consistent results.
