Rifle scopes enable you to precisely align a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnifying the target by making use of a set of lenses within the scope. The scope’s alignment can be dialed in to account for numerous ecological things like wind and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based on the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle scopes and optics have around eleven parts which are located internally and externally on the scope body. These optic pieces include the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of rifle scopes.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the optimal type of rifle optic depends on what type of shooting you plan to do.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are marginal
- Experienced shooters who know their target “hold over” and also “lead” correlations for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle behind the zoom lens. This induces the reticle to remain at the exact same dimensions relative to the amount of magnification being used. The result is that the reticle measurements change based on the zoom applied to shoot over longer ranges since the markings represent different increments which differ with the magnification. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement. These particular styles of scopes work for:
- Far away forms of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and proximities
- Shooters who choose a clearer optic picture with less area taken up by the enlarged FFP reticle
Magnification for Rifle Scopes
The amount of scope magnification you need on your glass depends upon the style of shooting you intend to do. Just about every type of rifle optic gives some amount of zoom. The level of magnification a scope gives is established by the diameter, thickness, and curves of the lens glass inside of the rifle optic. The magnifying level of the scope is the “power” of the glass. This signifies what the shooter is checking out through the scope is magnified times the power factor of what can usually be seen by human eyes.
Info on Fixed Single Power Lens Optics
A single power rifle scope will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not adjust because it is a set power scope.
About Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be adjusted between magnification levels. It will list the zoom level in a format like 2-10×32. These numbers imply the zoom of the scope could be set in between 2x and 10x power. This additionally incorporates the powers in-between 2 and 10. The power shift is accomplished by employing the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power and Range of Rifle Glass
Here are some suggested scope power settings and the ranges where they could be efficiently used. Remember that higher power optics will not be as practical as lower powered optics since too much zoom can be a detractor. The same concept relates to extended ranges where the shooter needs to have increased power to see where to best aim the rifle at the target.
Details on Rifle Optic Lens Covering
All contemporary rifle scope lenses are layered. There are various types and qualities of glass finishings. When considering high end rifle optics and scope systems, Lens covering can be an essential element of defining the capability of the rifle. The lenses are one of the most key parts of the optic as they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses shields the lens surface and assists with anti glare from excess daylight and color profiles.
About Optic Lens Coatings – HD Versus ED
Some optic manufacturers also use “HD” or high-definition lens finishings which use various procedures, polarizations, components, and chemicals to draw out separate color ranges and viewable target definition through the lens. This high-definition coating is often used with higher density glass which drops light’s chance to refract through the lens glass. Some scope corporations use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around things with well defined outlines as light hits the item from certain angles.
Single Coating Versus Multi-Coating
Different optic lenses can even have different coatings applied to them. All lenses usually have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently functional in many types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope designer and how much money you spent for it. Both the manufacturer and amount are signs of the lens quality.
Some scope makers likewise make it a point to define if their optic lenses are layered or “multi” coated. This implies the lens has numerous treatments applied to the surfaces. If a lens gets several treatments, it can establish that a maker is taking numerous actions to fight various environmental factors like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This also does not necessarily suggest the multi-coated lens will perform better than a single covered lens. Being “better” hinges on the producer’s lens treatment innovation and the quality of products used in creating the rifle optic.
Hydrophobic Rifle Scope Lens Finishing
Water on a scope lens does not assist with maintaining a clear sight picture through a scope in any way. Numerous top of the line and premium optic makers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the exterior surfaces of the Steiner optic lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to keep a clear, water free sight picture.
Options for Installing Glass on Firearms
Installing solutions for scopes are available in a few choices. There are the basic scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also usually can be found in quick release variations which use manual levers which permit rifle operators to rapidly mount and remove the scopes.
Scope Mounts with Hex Key Rings
Basic, clamp style mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mount rails on rifles. These forms of scope mounts use double detached rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are developed for long distance precision shooting. This form of scope mount is ideal for rifle systems which are in need of a durable, unfailing mount which will not shift no matter how much the scope is moved about or jarring the rifle takes. These are the design of mounts you should have for a dedicated scope setup on a long distance hunting or hard target interdiction rifle which will pretty much never need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to stop the hex screw threads from backing out after they are mounted tightly in place. An example of these mounting rings are the 30mm style from the Vortex Optics company. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. If they all use a comparable design mount, multiple scopes can often be switched out on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining precision. These kinds of mounts come in convenient for shooting platforms which are moved around a lot, to remove the scope from the rifle for protection, or for optics which are chosen for use between multiple rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
About Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your pricey optic by triggering fogging and developing residue inside of the scope tube. Many scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Optic Gas Purging
Another component of avoiding the accumulation of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the scope is less altered by condition alterations and pressure variations from the outdoor environment which could possibly allow water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
