Rifle Scope Details
Rifle scopes allow you to exactly aim a rifle at different targets by lining up your eye with the target over a distance. They do this through zoom by using a series of lenses inside the scope. The scope’s alignment can be dialed in for consideration of various environmental things like wind and elevation to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based upon the sight picture you are seeing using the scope as you align the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle scopes have around eleven parts which are located within and on the exterior of the scope. These scope parts consist of the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
About Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the finest type of rifle optic is based on what type of shooting you plan to do.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are minor
- Experienced shooters who know their target “hold over” plus “lead” correlations for their firearms
- Shooters who don’t mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Second Focal Plane Optic Details
Second focal plane glass (SFP) feature the reticle behind the magnification lens. This triggers the reticle to remain at the exact same overall size in connection with the amount of zoom being used. The final result is that the reticle measurements shift based on the zoom applied to shoot over lengthier distances due to the fact that the reticle measurements present distinct increments which vary with the magnification level. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These particular kinds of optics work for:
- Far away forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots happen within shorter proximities and ranges
- Shooters who choose a clearer optic sight picture with less space taken up by the enlarged FFP reticle
Details on Glass Magnification
The amount of magnification a scope provides 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 on Fixed Single Power Lens Glass
A single power rifle scope uses a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not fluctuate given that it is a fixed power optic.
Info About Variable Power Lens Rifle Scopes
Variable power rifle scopes use enhanced power. The power adjustment is performed by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range
Here are some suggested scope power settings and the ranges where they could be effectively used. Consider that higher power glass will not be as practical as lower powered optics and scopes due to the fact that too much magnification can be a negative thing in certain situations. The same concept goes for longer distances where the shooter needs to have enough power to see where to properly aim the rifle at the target.
Scope Lens Finishing
All modern-day rifle optic and scope lenses are covered in special coatings. There are different types and qualities of lens coverings. Lens covering can be an important element of a rifle when contemplating high end rifle optics and scope equipment. The glass lenses are among the most important parts of the scope because they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses offers protection to the lens exterior and helps with anti glare capabilities from excess daylight and color perception.
ED Versus HD Optics
Some scope manufacturers also use “HD” or high-definition lens coatings which use various processes, chemicals, polarizations, and components to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Info on Single Finishing Versus Multi-Coating
Different optic lenses can even have different coverings applied to them. All lenses normally have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic assembly. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in lots of kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers similarly make it a point to define if their optic lenses are coated or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of products used in constructing the rifle scope.
Hydrophobic Rifle Scope Lens Covering
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Many top of the line and high-end scope manufacturers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It deals with the exterior surfaces of the Steiner scope lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Scope Mounting Options
Installing approaches for scopes come in a couple of choices. 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 normally are made in quick release versions which use throw levers which permit rifle operators to rapidly install and dismount the optics.
Hex Key Glass Ring Mounting Solutions
Standard, clamp-on design mounting optic rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These styles of scope mounts use a pair of individual rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are created for far away accuracy shooting. This kind of scope mount is good for rifles which need a long lasting, unfailing mount which will not shift regardless of just how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should get for a devoted optics system on a long distance scouting or tournament rifle which will pretty much never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to prevent the hex screw threads from backing out after they are installed securely in position. An example of these mounting rings are the 30mm style made by Vortex Optics. The set generally costs around $200 USD
Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and attach it to a different rifle. Several scopes can also be switched out if they all use a compatible design mount. These types of mounts are handy for rifles which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between numerous rifles or are situationally focused.
What to Know About Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. The majority of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Rifle Scope Gas Purging
Another component of avoiding the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is currently taken up by the gas, the glass is less affected by temperature shifts and pressure distinctions from the outside environment which may potentially allow 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 seek out.
