The Basics of Rifle Scopes: Brief Overview

06/13/2023

Picture yourself lying on a shooting mat with your preferred rifle propped up in front of you on a bipod. You peep downrange at the gently sloping slopes and valleys that rise and fall in a sea of grass. A faint reflection of whatever catches the sun's rays can be seen off in the distance; it has a strangely geometric design that stands out against the verdant surroundings.

Your target is the polygonal steel slab that needs to be hit with your shot. The issue is that you hardly even see it because it resembles a postage stamp protruding from a sea of land. However, you sit down with your rifle and look through the attached scope. The rifle scopes help in better target shooting, and it is an essential accessory when you want to be a perfect marksman shooter.

The tiny target becomes more visible as the crosshairs are superimposed over the plate's center. You control your breathing, slide your finger slowly inside the trigger guard, and then effortlessly press backward. As the gun discharges, you hear a distant but welcome "pang" as your bullet strikes the plate.

Although a well-placed and long-distance shot results from good mechanics, practice, and execution, the rifle scope surely assists you in locating and capturing the target you just hit.

Simply put, a riflescope is a device with several magnifying lenses and some kind of reticle, an aiming tool that shows where your bullet may strike. Imagine placing crosshairs on the telescope you used to observe Venus as a child.

The configurations, designs, materials, sizes, and price ranges of scopes are incredibly diverse. Sport shooters can (and often do) fight for hours over which scope manufacturer, magnification, or reticle is most appropriate for the job. Still, we'll save you the opinions and focus on the fundamentals of how rifle scopes function.

A riflescope's objective, erector, magnifying, and ocular lenses are its most crucial parts. The objective lens is placed in front and away from the user in the tube. The light from this lens travels to the erector lens, which flips the image and delivers it to the magnification lens, which does what its name suggests and enlarges the image. The ocular lens, closest to the user's eye, receives the light from there. The ocular lens is enclosed within the eyepiece, the erector and magnifier lenses are housed within the scope tube, and the objective lens is kept inside the objective bell.

The "eye relief" of scope refers to how far the shooter's eye is from the eyepiece while still being able to see the whole field of view. The scope will be closer to the user's face and farther from the gun stock when the eye relief is less. In contrast, long eye relief scopes, like those seen on scout rifles, provide a wide gap between the eyepiece and the eye, allowing the gun to be positioned further forward.

Most rifle scope lenses are fog and water-resistant, which is essential given the variety of conditions in which shooters may need to see their intended target. The manufacturer seals gaps among the lenses and housing of optical equipment to make it watertight.

Rifle scopes are available in all price ranges, with versions that cost less than $100 to several thousand dollars worth of precision optics.
