Rifle scopes enable you to exactly aim a rifle at various targets by lining up your eye with the target at range. They do this through magnification by making use of a set of lenses within the scope. The scope’s positioning can be adjusted to take into account varied environmental aspects like wind and elevation increases to account for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based on the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle scopes have around eleven parts which are arranged internally and on the exterior of the optic. These optic pieces include the rifle scope’s body, lenses, adjustment turrets, focus rings, and other elements. See all eleven parts of an optic.
About Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Going for the finest type of rifle glass depends 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 beneficial for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are small
- Experienced shooters who recognize their target “hold over” and also “lead” ratios for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual sight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the zoom lens. This causes the reticle to stay at the same overall size relative to the quantity of zoom being used. The final result is that the reticle measurements shift based on the magnification used to shoot over lengthier ranges due to the fact that the markings represent various increments which differ with the magnification. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These types of optics are handy for:
- Far away forms of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots take place within shorter distances and ranges
- Shooters who like a clearer optic sight picture with less area taken up by the larger sized FFP reticle
Rifle Scope 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 magnification of the scope is the “power” of the scope.
Single Power Lens Rifle Glass
A single power rifle scope or optic comes with a magnification 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 type of optic can not change given that it is a fixed power scope.
Variable Power Lens Glass Facts
Variable power rifle scopes use enhanced power. The power adjustment is handled by using the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range of Glass
Here are some suggested scope power settings and the ranges where they may be efficiently used. Highly magnified glass will not be as beneficial as lower magnification rifle scope glass considering too much zoom can be a bad thing. The exact same idea goes for longer distances where the shooter needs enough power to see precisely where to properly aim the rifle at the target.
Scope Lens Finishing
All current rifle glass lenses are layered. Lens finishing can be a vital aspect of a shooting platform when looking into high end rifle optics and scope setups.
Details on Lens Coatings – HD Versus ED
Some glass manufacturers also use “HD” or high-def glass coverings that use various procedures, polarizations, elements, and chemicals to draw out different colors and viewable definition through lenses. This high-definition finishing is normally used with increased density glass which drops light’s potential to refract by means of the lens glass. Some scope corporations use “HD” to refer to “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 can be noticeable around objects with well defined outlines as light hits the item from various angles.
Single Rifle Scope Lens Finish Versus Multi-Coating
Different optic lenses can likewise have various finishings applied to them. All lenses usually have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can safeguard the lens from scratches while decreasing 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 upon the scope producer and the amount you spent paying for it. The scope’s maker and cost are indications of the lens quality.
Some scope manufacturers likewise make it a point to specify if their optic lenses are covered or “multi” coated. This indicates the lens has had several treatments applied to them. If a lens receives multiple treatments, it can prove that a company is taking numerous steps to combat different environmental factors like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This also doesn’t always imply the multi-coated lens is better than a single layered lens. Being “much better” depends on the manufacturer’s lens treatment techniques and the quality of components used in creating the rifle scope.
Anti-water Lens Finish
Water on an optic’s lens doesn’t support retaining a clear sight picture through a scope whatsoever. Numerous top of the line or high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It provides protection for the surface area of the Steiner glass lens so the water particles can not bind to it or produce surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Rifle Glass Mounting Options
Mounting options for scopes are available in a couple of options. 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 normally come in quick release variations which use toss levers which allow rifle operators to rapidly install and dismount the optics.
Hex Key Rifle Optic Ring Mounting Solutions
Standard, 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 two separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope install is great for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Scope Ring Mounting Solutions
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 similar style mount, several scopes can often be switched on the range. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving accuracy. These types of mounts are useful and practical for rifles which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are employed between several rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It usually costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope tube. Many scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Rifle Scope Gas Purging
Another element of preventing the accumulation of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the scope is less affected by temperature level alterations and pressure variations from the external environment which might possibly allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
