What is the most likely reason for inaccuracy after mounting or removing an optic?

• A. The mount shifted the point of impact
• B. The trigger weight changed
• C. The magazine feed reliability changed
• D. The grip texture changed

Answer: (A)

Mounting an optic creates a new reference between the rifle’s bore and the reticle. If the mount shifts when you install or remove the optic—torque on the screws changes, the seating isn’t identical, or there’s even a slight cant—the rifle’s zero moves. That change in alignment is what causes bullets to strike at a different point than where you aimed, making it the most likely source of inaccuracy after mounting or removing an optic. Other factors like trigger weight, magazine reliability, or grip texture don’t directly alter the optical zero; they affect shooter feel or feeding, not the alignment between the bore and the optic. The remedy is to re-zero after remounting and ensure proper mounting torque and level, so the point of impact returns to where you expect it.
