Tech Talk
Magnification (Power): Riflescopes are often referred to by two numbers separated by an “x”. For example: 4×40. The first number is the power or magnification of the scope. With a “4x”, the object being viewed appears to be four times closer than when seen with the unaided eye.
Objective Lens Size: The second number in the formula (4×40) is the diameter of the objective or front lens. The larger the objective lens, the more light that enters the scope, and the brighter the image.
Field of View (F.O.V.): The side-to-side measurement of the circular viewing field or subject area. It is defined by the width in feet or meters of the area visible at 1000 yards or meters. A wide angle binocular features a wide field of view and is better for following action. Generally, the higher the magnification, the narrower the field of view.
Reticle: A reticle is the crosshair or pattern placed in the eyepiece of the scope which establishes the gun’s position on the target.

What You Need to Know About Rifle Scopes
Rifle scopes enable you to specifically aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnification by employing a set of lenses within the scope. The scope’s positioning can be adapted for consideration of separate ecological things like wind and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based on the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of modern rifle scopes have around eleven parts which are found internally and externally on the optic. These optic pieces consist of the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other components. Learn about the eleven parts of scopes.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the finest type of rifle optic is based on what type of shooting you plan on doing.
About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This causes the reticle to increase in size based on the extent of zoom being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non magnified distance. As an example, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are very little
- Experienced shooters who understand their aim point “hold over” plus “lead” equations for their rifles
- Shooters who don’t mind the reticle is bigger and takes up more visual sight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the zoom lens. This causes the reticle to remain at the very same scale relative to the amount of magnification being used. The effect is that the reticle measurements adapt based upon the magnification applied to shoot over lengthier ranges considering the markings represent different increments which differ with the magnification. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These styles of scopes work for:
- Far away kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots happen within shorter ranges and proximities
- Shooters who choose a clearer optic sight picture without room used up by the larger size FFP reticle
About Rifle Glass Magnification
The quantity of magnification a scope supplies is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Scopes
A single power rifle scope and optic uses a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not fluctuate considering that it is fixed.
Info on Variable Power Lens Rifle Optics
Variable power rifle scopes can be tweaked between magnified settings. The power change is achieved by using the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range of Optics
Here are some suggested scope power settings and the ranges where they may be effectively used. Keep in mind that higher power glass will not be as effective as lower magnification level optics and scopes since increased zoom can be a negative thing in certain situations. The exact same concept goes for extended distances where the shooter needs to have enough power to see exactly where to properly aim the rifle.
Lens Finish for Rifle Optics
All modern-day rifle optic lenses are covered in special coatings. There are different types and qualities of lens finishes. When thinking about high end rifle optics and scope setups, Lens coating can be a vital aspect of a rifle. The glass lenses are among the most significant components of the glass due to the fact that they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses shields the lens surface and assists with anti glare from excess natural light and color profiles.
ED Versus HD Optics
Some rifle scope producers even use “HD” or high-definition lens coatings which use various procedures, elements, chemical substances, and polarizations to draw out numerous colors and viewable target definition through the lens. This high-def finishing is frequently used with more costly high density lens glass which lowers light’s opportunity to refract by means of the lens glass. Some scope corporations use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how colors are represented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration is often noticeable around items with hard edges and shapes as light hits the item from various angles.
Glass Lens Single Finishing Versus Multi-Coating
Various optic lenses can also have different finishes applied to them. All lenses generally have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and just how much you spent on it. Both are signs of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” coated. This suggests the lens has numerous treatments applied to the surfaces. If a lens receives numerous treatments, it can establish that a maker is taking numerous steps to fight different natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This additionally doesn’t always mean the multi-coated lens is better than a single layered lens. Being “better” depends on the producer’s lens treatment innovation and the quality of materials used in creating the rifle glass.
Scope Lens Hydrophobic Finish
Water on a scope’s lens doesn’t help with preserving a clear sight picture through a scope in any way. Numerous top of the line or premium optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the surface area of the Steiner optic lens so the H2O particles can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Alternatives for Installing Glass on Firearms
Installing approaches for scopes are available in a couple of choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually are made in quick release versions which use toss levers which allow rifle operators to rapidly mount and dismount the optics.
Hex Key Rifle Scope Ring Mounts
Standard, clamp type mounting scope rings use hex head screws to position to the flattop style Picatinny scope mounting rails on rifles. These kinds of scope mounts use double individual rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are made for long distance precision shooting. This type of scope mount is very good for rifles which need to have a durable, unfailing mount which will not change no matter just how much the scope is moved about or abuse the rifle takes. These are the type of mounts you should have for a faithful scope system on a reach out and touch someone hunting or tournament long gun that will almost never need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used to prevent the hex screw threads from wiggling out after they are mounted firmly in place. An example of these rings are the 30mm style made by Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle before reattaching it to a different rifle. Several scopes can even be switched out if they all use a similar style mount. These types of mounts are handy for rifles which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used between numerous rifles or are situationally focused.
What to Know About Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your pricey optic by bringing about fogging and developing residue inside of the scope tube. A lot of scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Scope Tubes
Another component of preventing the buildup of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the optic is less influenced by temp shifts and pressure variations from the outdoor environment which may possibly permit water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
