All About Rifle Scopes
Rifle scopes enable you to exactly aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through zoom using a series of lenses within the scope. The scope’s alignment can be adjusted to take into account numerous natural things like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes and optics have around 11 parts which are found internally and outside of the scope. These parts consist of the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other components. Learn about the eleven parts of optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane an optic has identifies where the reticle or crosshair is located relative to the scopes magnification. It literally indicates the reticle is behind or before the magnification lens of the optic. Choosing the most desired kind of rifle glass depends on what kind of hunting or shooting you anticipate doing.
First Focal Plane Glass Facts
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are minor
- Experienced shooters who know their target “hold over” as well as “lead” equations for their long gun
- Shooters who do not mind the reticle is enlarged and occupies more visual eyesight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Far away forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots happen within much shorter ranges and proximities
- Shooters who choose a clearer optic picture without space taken up by the bigger FFP reticle
Magnification for Glass
The amount of scope zoom you require depends upon the kind of shooting you choose to do. Practically every kind of rifle glass supplies some level of zoom. The level of magnification a scope gives is established by the size, thickness, and curvatures of the lenses inside of the rifle optic. The magnification 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 element of what can typically be seen by human eyes.
Fixed Power Lens Glass
A single power rifle scope will have a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not change given that it is set from the factory.
Variable Power Lens Glass Facts
Variable power rifle scopes use enhanced power. The power change is accomplished by making use of the power ring part of the scope near the back of the scope by the eye bell.
Rifle Glass Power and Range Correlation
Here are some recommended scope power settings and the ranges where they could be effectively used. Highly magnified glass will not be as effective as lower magnification level scopes considering that too much magnification can be a bad thing. The exact same idea goes for longer distances where the shooter needs to have adequate power to see where to properly aim the rifle.
Optic Lens Coating
All modern-day rifle scope lenses are layered. There are different types and qualities of glass lens coatings. When considering high end rifle scope setups, Lens coating can be a vital element of defining the rifle’s capability. The lenses are among the most significant pieces of the optic considering that they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses safeguards the lens surface area and also helps with anti glare capabilities from excess light and color presence.
HD Versus ED Rifle Optic Lens Coatings
Some rifle glass manufacturers will also use “HD” or high-def lense finishes that use various procedures, rare earth compounds, polarizations, and elements to extract a wide range of colors and viewable definition through lenses. This high-definition coating is typically used with more costly high density lens glass which decreases light’s ability to refract through the lens glass. Some scope suppliers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be obvious over objects with hard outlines as light hits the object from specific angles.
Single Coating Versus Multi-Coating for Optics
Various optic lenses can also have various coatings applied to them. All lenses typically have at least some kind of treatment or finishing applied to them before being used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It needs to have a covering applied to it so that it will be efficiently usable in numerous types of environments, degrees of sunshine (full VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” coated. This implies the lens has numerous treatments applied to the surfaces of the glass. If a lens gets several treatments, it can prove that a producer is taking multiple actions to fight different natural factors like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This additionally does not necessarily mean the multi-coated lens will perform much better than a single coated lens. Being “much better” is dependent on the manufacturer’s lens treatment techniques and the quality of products used in constructing the rifle optic.
Info on Hydrophobic Covering
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish which is water repellent.
Choices for Mounting Rifle Scopes on Firearms
Installing solutions for scopes come in a couple of options. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually can be found in quick release versions which use throw levers which permit rifle operators to rapidly install and remove the optics.
Hex Key Optic Ring Mounts
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope install is perfect for rifles which need a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle. A wide range of scopes can also be swapped out if they all use a similar style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely 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 the original sighting settings. These types of mounts come in beneficial for shooting platforms which are carried a lot, to take off the optic from the rifle for protection, or for sight systems which are used in between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can ruin a day on the range and your expensive optic by triggering fogging and creating residue inside of the scope’s tube. Most scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are water resistant. Generally, these optics can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of humidity avoidance for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle boating and are concerned about the scope still working if it goes over the side and you can still find the rifle.
Rifle Scope Gas Purging
Another component of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is already taken up by the gas, the scope is less impacted by condition changes and pressure variations from the external environment which might possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
