Rifle Scope Basics

Learn how to level rifle scope with simple steps, pro tools, and zero-wobble tips. Boost accuracy fast and avoid common mistakes. Read before you mount.

Side focus on a rifle scope is a side-mounted knob, usually on the left, that adjusts parallax by moving an internal lens. This adjustment places the target and reticle in the same focal plane, eliminates reticle shift, and ensures accuracy at varying distances, especially beyond 100 yards and at magnifications […]

Turn the rifle scope turrets in the direction you want the bullet impact to move. If shots hit low, turn the elevation dial “UP” (usually counter-clockwise). If shots hit left, turn the windage dial “R” (usually counter-clockwise). Most scopes adjust 1/4 inch per click at 100 yards, following the “move […]

Clean a rifle scope by removing loose dust with a blower or soft brush, then wiping the lenses gently from center to edge using a microfiber cloth and lens cleaner or 90%+ isopropyl alcohol. Avoid ammonia-based cleaners like Windex. Finish with a dry wipe and clean the scope body with […]

The military uses rifle scopes such as the Trijicon ACOG, Leupold Mark 5HD, and advanced systems like the Vortex XM-157. Common optics include LPVOs for general combat, high-magnification scopes for sniping, and red dot or holographic sights like Trijicon RMR and EOTech, depending on mission and weapon system. Close-Quarters Combat […]

Choose a rifle scope for deer hunting by prioritizing low-light clarity, durability, and versatile magnification. A 3-9x40mm or 3-9x50mm scope is the standard choice. A 3-9x zoom balances close shots in thick cover and longer shots in open fields, while a 30mm tube improves dawn and dusk light transmission.” Understand […]

Calibrate a rifle scope by mounting it securely, bore sighting for initial alignment, and shooting groups to adjust the turrets. Turn windage and elevation turrets until the point of aim matches the point of impact. Finalize calibration by setting the turrets to zero and confirming reticle alignment. Understand Your Scope […]

Measure rifle scope height as the distance from the center of the bore to the center of the scope tube, typically 1.5–2.5 inches. Use calipers to measure from the top of the receiver to the bottom of the scope tube, then add half the bolt diameter and half the scope […]

Parallax in a rifle scope is an optical error where the reticle and target are on different focal planes. This misalignment causes the reticle to appear to move when your eye shifts, reducing accuracy at varying distances. Shooters correct parallax using adjustable objective lenses or side focus knobs. What is […]

Keep a rifle scope from fogging up by managing temperature changes and moisture exposure. Allow the scope to acclimate before use, use lens covers to block humidity, and apply anti-fog sprays or wipes to exterior lenses. For long-term prevention, store the rifle in a dry, climate-controlled environment. Identify the Type […]
