Why should you verify your zero after mounting or removing an optic?

• A. Mount changes can shift the point of impact; re-zero ensures accuracy.
• B. Optics always stay zero regardless of mounting.
• C. Zero is not important for accuracy.
• D. Mount changes only affect aesthetics.

Answer: (A)

When you mount or remove an optic, the alignment between the bore and the reticle can shift. The optic’s height, angle, and exact seating on the rail, plus screw torque and contact surfaces, can nudge where the reticle points relative to where the bullet actually hits. Verifying zero after mounting or removal is necessary to ensure your point of aim and point of impact match at your chosen distance, giving you predictable and accurate shots. This isn’t just a theoretical concern—mount changes can and do alter the zero, while misassumptions that zero will stay put or that changes only affect appearance lead to missed targets. Re-zeroing catches those shifts and keeps you confident in your setup.
