Information About Rifle Optics
Rifle scopes permit you to exactly align a rifle at various targets by aligning 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 positioning can be adapted to take into account varied environmental things like wind and elevation decreases to account 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 seeing using the optic as you line up the scope’s crosshair or reticle with the target. The majority of contemporary rifle scopes have around 11 parts which are arranged within and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other elements. See all eleven parts of a rifle scope.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane a scope has decides where the reticle or crosshair is located relative to the optic’s zoom. It simply indicates the reticle is located behind or ahead of the magnifying lens of the scope. Deciding on the most reliable kind of rifle scope is dependent on what form of shooting you intend on doing.
Info on First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where calculations are very little
- Experienced shooters who have an idea for their target “hold over” and also “lead” correlations for their rifles
- Shooters who do not mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane optics (SFP) come with the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots occur within much shorter ranges and proximities
- Shooters who would like a clearer optic sight picture with less area taken up by the enlarged FFP reticle
About Optic Zoom
The measure of scope zoom you need on your glass depends upon the type of shooting you choose to do. Practically every type of rifle optic supplies some level of magnification. The quantity of zoom a scope delivers is established by the diameter, thickness, and curvatures of the lens glass within the rifle optic. The zoom of the scope is the “power” of the scope. This means what the shooter is checking out through the scope is magnified times the power factor of what can usually be seen by human eyes.
About Single Power Lens Scopes
A single power rifle optic will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not change because it is a set power scope.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be modified between magnified levels. The power adjustment is achieved by using the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range
Here are some recommended scope powers and the distances where they can be effectively used. Consider that higher power scopes and optics will not be as practical as lower powered optics since increased zoom can be a negative thing in certain situations. The very same idea relates to longer distances where the shooter needs increased power to see precisely where to best aim the rifle at the target.
Details on Lens Coating
All contemporary rifle optic and scope lenses are covered in special coatings. There are various types and qualities of glass lens coatings. Lens covering can be an important element of a rifle when thinking of luxury rifle optics and targeting systems. The glass lenses are among the most important pieces of the scope because they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses protects the lens surface area and improves anti glare from excess sunlight and color exposure.
About Glass Lens Coatings – HD Versus ED
Some glass suppliers additionally use “HD” or high-def lense finishes which employ various procedures, rare earth compounds, elements, and polarizations to extract a wide range of color ranges and viewable definition through the lens. This high-def covering is typically used with more costly high density glass which decreases light’s capability to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how colors are represented on the chroma spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration may be noticeable around objects with hard edges and outlines as light hits the item from certain angles.
What to Know About Single Finish Versus Multi-Coating
Various optic lenses can even have different coverings applied to them. All lenses normally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. Because the lens isn’t just 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 the lens will be optimally usable in many kinds of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while reducing glare and other less beneficial 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 manufacturers also make it a point to define if their optic lenses are coated or “multi” coated. This means the lens has multiple treatments applied to them. If a lens receives numerous treatments, it can establish that a company is taking several actions to fight various natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This also doesn’t always suggest the multi-coated lens will perform much better than a single covered lens. Being “much better” is dependent on the producer’s lens treatment innovation and the quality of products used in creating the rifle scope.
Rifle Optic Lens Hydrophobic Coating
Water on a lens doesn’t improve keeping 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 hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the exterior surfaces of the Steiner optic lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Options for Installing Rifle Optics on Firearms
Installing approaches for scopes come in a few choices. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally can be found in quick release versions which use manual levers which allow rifle operators to rapidly mount and dismount the scope.
Rifle Glass Mounts with Hex Key Rings
Normal, clamp design 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 made from 7075 T6 billet aluminum which are created for long range accuracy shooting. This type of scope install is perfect for rifles which require a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be switched out if they all use a compatible design mount. These types of mounts come in handy for rifle platforms which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles.
What to Know About Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can mess up a day on the range and your highly-priced optic by triggering fogging and producing residue within the scope tube. The majority of scopes protect against wetness from getting in the optical tube with a system of sealing O-rings which are water resistant. Typically, these water resistant scopes can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture content prevention for common use rifles, unless you anticipate taking your rifle on your motorboat and are concerned about the scope still working if it is submerged in water and you can still rescue the gun.
Rifle Optic Gas Purging
Another element of preventing the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the glass is less altered by climate changes and pressure variations from the outside environment which could potentially 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.
