Information Rifle Scopes
Rifle scopes allow you to exactly aim a rifle at various targets by lining up your eye with the target over a distance. They do this through magnifying the target by using a series of lenses inside the scope. The scope’s positioning can be adapted to account for separate ecological things like wind and elevation decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based upon the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes have around 11 parts which are found internally and externally on the scope. These scope parts include the rifle scope’s body, lenses, modification dials, focus rings, and other elements. See all eleven parts of optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the best type of rifle glass is based on what type of shooting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are small
- Experienced shooters who understand their target “hold over” plus “lead” relationships for their firearms
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane optics (SFP) include the reticle behind the zoom lens. This triggers the reticle to remain at the very same size in relation to the quantity of zoom being used. The result is that the reticle measurements adapt based upon the zoom employed to shoot over greater ranges considering that the reticle markings represent distinct increments which vary with the magnification level. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These types of glass work for:
- Far away types of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots take place within shorter proximities and ranges
- Shooters who would like a clearer optic sight picture without area used up by the enlarged FFP reticle
Rifle Glass Magnification
The level of scope zoom you need on your optic depends on the kind of shooting you want to do. Virtually every style of rifle glass supplies some level of zoom. The amount of magnification a scope provides is established by the size, density, and curvatures of the lenses within the rifle scope. The magnification of the optic is the “power” of the glass. This indicates what the shooter is observing through the scope is magnified times the power factor of what can typically be seen by human eyes.
About Single Power Lens Scopes
A single power rifle scope and optic will have a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust given that it is a set power scope.
Info About Adjustable Power Lens Glass
Variable power rifle scopes can be modified between magnified levels. The power modification is accomplished by the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some advised scope power levels and the ranges where they can be efficiently used. High power scopes will not be as efficient as lower magnification rifle scope glass considering too much magnification can be a negative aspect depending on your shooting distance. The same concept relates to extended distances where the shooter needs sufficient power to see exactly where to best aim the rifle at the target.
About Lens Finish
All current rifle optic lenses are covered. Lens finishing is an important element of a rifle system when considering high end rifle optics and scope equipment.
HD Versus ED Lenses
Some rifle scope suppliers also use “HD” or high-definition lense coatings which use different processes, elements, rare earth compounds, and polarizations to extract a wide range of colors and viewable target definition through lenses. This high-def coating is frequently used with more costly high density glass which brings down light’s ability to refract by means of the lens glass. Some scope brands use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how colors are represented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration is often obvious around items with hard outlines as light hits the item from various angles.
Single Rifle Glass Lens Coating Versus Multi-Coating
Different optic lenses can even have different finishes applied to them. All lenses usually have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally usable in many kinds of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope designer and how much money you spent paying for it. Both the make and cost are signs of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are layered or “multi” covered. Being “much better” depends on the maker’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Details on Anti-water Coating
Water on a lens doesn’t help with maintaining a clear sight picture through an optic in any way. Many top of the line and premium optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the surface 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 slide off of the scope to keep a clear, water free sight picture.
Optic Installation Choices
Installing approaches for scopes come in a few options. There are the basic scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually are made in quick release variations which use toss levers which allow rifle shooters to quickly install and remove the optics.
Rifle Optic Mounts with Hex Key Rings
Standard, clamp type mounting scope rings use hex head screws to install to the flattop design Picatinny scope mount rails on rifles. These kinds of scope mounts use two independent rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are manufactured for far away precision shooting. This type of scope mount is good for rifle systems which need to have a long lasting, unfailing mount which will not change no matter just how much the scope is moved or abuse the rifle takes. These are the design of mounts you want for a dedicated optics setup on a reach out and touch someone hunting or competitors long gun which will hardly ever need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount screws to keep the hex screws from backing out after they are mounted safely in position. An example of these rings are the 30mm type from Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Glass Rings
These kinds of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. Several scopes can also be swapped out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining accuracy. These kinds of mounts are useful and convenient for shooting platforms which are moved around a lot, to remove the scope glass from the rifle for protection, or for optics which are used between several rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It normally costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope tube. The majority of scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Scope Gas Purging
Another component of preventing the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the optic is less affected by temperature changes and pressure differences from the external environment which might possibly permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
