Optic Information
Rifle scopes permit you to exactly align a rifle at various targets by aligning your eye with the target at range. They do this through magnifying the target by utilizing a series of lenses inside the scope. The scope’s positioning can be adjusted to account for different environmental aspects like wind and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the intended target. Most modern rifle scopes and optics have around eleven parts which are located internally and outside of the scope. These scope parts consist of the rifle scope’s body, lenses, adjustment dials, focus rings, and other parts. Learn about the eleven parts of optics.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the perfect type of rifle optic is based around what type of shooting you plan to do.
Info About First Focal Plane Scopes
First focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the extent of zoom being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non magnified distance. For example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who know their target “hold over” plus “lead” equations for their firearm
- Shooters who do not mind the reticle is bigger and requires more visual sight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane glass (SFP) come with the reticle to the rear of the magnifying lens. This causes the reticle to stay at the exact same size relative to the amount of magnification being used. The result is that the reticle measurements shift based upon the magnification applied to shoot over greater distances considering the reticle measurements present various increments which can 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 measurement. These sorts of glass work for:
- Long distance forms of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who desire a clearer optic picture without area taken up by the larger sized FFP reticle
Ins and Outs of Rifle Scope Zoom
The amount of magnification a scope supplies is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Optic Info
A single power rifle scope uses a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change considering that it is set from the factory.
About Adjustable Power Lens Optics
Variable power rifle scopes can be tweaked between magnified settings. The power adjustment is achieved using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some recommended scope powers and the ranges where they may be successfully used. High power optics will not be as effective as lower powered optics considering too much magnification can be a negative aspect depending on your shooting distance. The same relates to extended ranges where the shooter needs enough power to see exactly where to best aim the rifle.
Info on Rifle Glass Lens Finishes
All current rifle scope lenses are coated. Lens covering can be a vital aspect of a rifle’s setup when looking into high end rifle optics and scope equipment.
Details on Glass Lens Coatings – HD Versus ED
Some rifle scope makers even use “HD” or high-def lens finishings that employ different procedures, components, compounds, and polarizations to enhance separate color ranges and viewable target visibility through lenses. This HD finish is normally used with more costly high density lens glass which lowers light’s ability to refract by means of the lens glass. Some scope vendors use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration may be visible over things with defined outlines as light hits the object from particular angles.
Single Rifle Optic Lens Coating Versus Multi-Coating
Various scope lenses can even have various coverings applied to them. All lenses normally have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be optimally functional in numerous types of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can preserve 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 covered lens depends upon the scope company and just how much you spent on it. Both the make and cost are indications of the lens quality.
Some scope producers also make it a point to define if their optic lenses are layered or “multi” covered. This indicates the lens has multiple treatments applied to them. If a lens receives numerous treatments, it can establish that a company is taking numerous actions to combat various natural elements like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This additionally doesn’t always indicate the multi-coated lens will perform much better than a single covered lens. Being “much better” hinges on the producer’s lens treatment solutions and the quality of materials used in creating the rifle scope.
Hydrophobic Lens Finish
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Many top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic finishing.
Alternatives for Installing Rifle Scopes on Firearms
Mounting options for scopes come in a few options. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually come in quick release variations which use throw levers which allow rifle operators to quickly mount and remove the scopes.
Hex Key Glass Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long distance accuracy shooting. This type of scope install is wonderful for rifles which need a long lasting, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Glass Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, several scopes can often be swapped on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach 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 retaining precision. These types of mounts are useful and practical for shooting platforms which are shipped a lot, to remove the scope glass from the rifle for protection, or for scopes which are used between numerous rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your costly optic by causing fogging and creating residue inside of the scope tube. The majority of scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another part of avoiding the buildup of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is currently occupied by the gas, the glass is less influenced by climate shifts and pressure distinctions from the external environment which may potentially allow water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
