Understanding Scope Numbers: A Tactical Shooter’s Guide

Texas Guns, Inc. | Stay Armed, Stay Safe.

When choosing a rifle scope for tactical shooting, understanding what the numbers on an optic actually mean is essential to performance and precision. Scope specs may look like a secret code—1-6x24, 3.5x35, 4-16x50—but once you learn how to read them, you’ll know exactly what kind of tool you’re working with. Let’s break it down in plain terms, and introduce a simple acronym to help you lock it in: M.A.R.S.

M.A.R.S. – A Simple Way to Read Scope Numbers

When looking at scope numbers like 1-6x24, apply the M.A.R.S. breakdown:

• M – Magnification Range (1-6x means you can zoom from 1x to 6x)
• A – Actual Zoom Levels (Fixed scopes have one number, like 4x; variable scopes list a range, like 3-9x)
• R – Reticle Use (More magnification means finer adjustments—choose reticles suited to your range)
• S – Size of Objective Lens (Measured in mm—24mm, 50mm, etc.—this affects light gathering and clarity)

Example: A 4-16x50 scope has a variable magnification from 4x to 16x, and a 50mm objective lens for excellent light transmission and clarity.

Tactical Distances & Scope Recommendations

Close-Range (0–100 yards):
You want speed and wide field of view.
Recommended:

• 1-4x or 1-6x scopes
• Red dot or LPVO (Low Power Variable Optic – a scope with a 1x low end and variable zoom, designed for fast transitions between close and mid-range targets)
• Ideal for home defense, CQB, or 3-Gun competitions

Mid-Range (100–400 yards):
You need a balance of magnification and quick target acquisition.
Recommended:

• 3-9x or 2-10x scopes
• Good for patrol rifles, defensive DMR builds, or hog hunting

Long-Range (400–800+ yards):
Precision and clarity are everything.
Recommended:

• 4-16x, 5-25x, or similar
• Perfect for PRS, long-range engagements, and sniper applications
