A Major Scope Defect You Need To Look For - The Problem You Didn't Know You Had!

Published on January 9, 2025
Duration: 11:49

This video from Paramount Tactical details a critical step in precision optic mounting: leveling the scope body, not the reticle. Instructor Gary explains how using the reticle for leveling can hide internal defects like reticle cant, leading to tracking issues and misses. He demonstrates how to properly level an optic using the scope body and a level, then verify reticle alignment with an angle indicator, emphasizing the importance of tracking and tall target tests for identifying mechanical problems.

Quick Summary

To properly level a rifle scope, avoid using the reticle as your reference. Instead, ensure the scope body is parallel to the scope base by referencing the bottom of the turret housing. This method reveals critical internal defects like reticle cant, which can cause significant tracking errors and misses at distance.

Frequently Asked Questions

Why should you avoid leveling a rifle scope using the reticle?

Leveling a scope using the reticle can hide internal defects like reticle cant. This means the scope body might appear level, but the reticle is off-axis, leading to inaccurate tracking and potential misses at distance.

What is the correct method for leveling a rifle scope?

The correct method is to level the scope body itself, ensuring it is parallel to the scope base. Use a reliable level and reference the bottom of the turret housing for a consistent, flat plane, rather than relying on the reticle's orientation.

How can you detect reticle cant in a rifle scope?

After leveling the scope body, use a laser level and an angle indicator (like an SG pulse) to check if the reticle is canted relative to the scope's body. This will reveal any internal misalignment that wasn't apparent when using the reticle for leveling.

What are the consequences of a canted reticle in a rifle scope?

A canted reticle causes the erector tube to move at an angle instead of straight up/down or left/right. This leads to tracking issues, where adjustments don't translate to the expected point of impact, resulting in misses, especially at longer ranges.
