What You Need to Know About Rifle Scopes
Rifle scopes enable you to precisely align a rifle at various targets by aligning your eye with the target over a range. They do this through zoom by making use of a set of lenses inside the scope. The scope’s positioning can be adjusted for consideration of separate environmental aspects like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the target. The majority of modern-day rifle scopes have around 11 parts which are located internally and outside of the optic. These scope parts include the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other components. Learn about the eleven parts of rifle glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the best type of rifle optic is based around what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are marginal
- Experienced shooters who understand their aim point “hold over” as well as “lead” relationships for their firearm
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle to the rear of the zoom lens. This triggers the reticle to stay at the very same dimensions relative to the amount of magnification being used. The end result is that the reticle measurements change based on the magnification applied to shoot over lengthier distances considering the markings present different increments which vary with the magnification. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular styles of scopes work for:
- Far away styles of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots occur within shorter ranges and spaces
- Shooters who prefer a clearer optic picture without area used up by the bigger FFP reticle
Ins and Outs of Rifle Optic Zoom
The quantity of zoom a scope offers is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Info About Single Power Lens Optics
A single power rifle scope uses a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate since it is a set power scope.
Info on Adjustable Power Lens Scopes
Variable power rifle scopes can be adjusted between magnification levels. These types of scopes will list the magnification level in a format such as 2-10×32. These numbers indicate the zoom of the scope could be set in between 2x and 10x power. This always includes the power levels in-between 2 and 10. The power shift is achieved by operating the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Glass Power Level and Range Correlation
Here are some advised scope power settings and the ranges where they may be efficiently used. Bear in mind that high magnification optics and scopes will not be as efficient as lower powered scope and optics because excessive zoom can be a negative thing in certain situations. The exact same concept relates to longer ranges where the shooter needs to have sufficient power to see exactly where to properly aim the rifle at the target.
Details on Lens Coverings
All contemporary rifle scope lenses are covered in special coatings. There are different types and qualities of glass finishes. Lens finish can be an essential element of a rifle when looking at luxury rifle optics and targeting units. The lenses are among the most essential components of the optic given that they are what your eye looks through while sighting a rifle in on the point of impact. The finishing on the lenses protects the lens surface area and improves anti glare from excess daylight and color visibility.
Info on Optic Lens Coatings – HD Versus ED
Some rifle glass companies also use “HD” or high-def lense coatings which employ different processes, rare earth compounds, components, and polarizations to enhance separate color ranges and viewable target definition through lenses. This HD finishing is normally used with more costly high density glass which brings down light’s chance to refract by means of the lens glass. Some scope vendors use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration may be obvious over things with well defined shapes as light hits the item from specific angles.
Single Coating Versus Multi-Coating
Various optic lenses can also have different finishings applied to them. All lenses usually have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Hydrophobic Lens Coverings
Water on a scope lens does not improve preserving a clear sight picture through an optic in any way. Many top of the line and high-end optic producers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It deals with the surface area of the Steiner scope lens so the H2O particles can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Choices for Mounting Rifle Scopes on Firearms
Mounting options for scopes are available in a few options. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also usually come in quick release versions which use toss levers which allow rifle operators to rapidly mount and remove the scope.
Scope Mounting Solutions with Hex Key Rings
Basic, clamp-on type mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use two detached rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are created for far away precision shooting. This kind of scope mount is great for rifles which require a long lasting, hard use mount which will not shift regardless of how much the scope is moved or abuse the rifle takes. These are the design of mounts you really want to have for a specialized optics setup on a reach out and touch someone scouting or interdiction rifle which will seldom need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on the screws to stop the hex screws from wiggling out after they are mounted firmly in position. An example of these rings are the 30mm style made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly detach a scope and connect it to a different rifle. Several scopes can also be switched out if they all use a compatible style mount. These types of mounts are handy for rifles which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used in between multiple rifles or are situationally focused.
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle scope can ruin a day of shooting and your costly optic by causing fogging and producing residue inside of the scope tube. A lot of scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Rifle Scope Gas Purging
Another component of avoiding the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the scope is less impacted by temperature level shifts and pressure differences from the outside environment which could possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
