About Rifle Scopes
Rifle scopes enable you to precisely align a rifle at various targets by aligning your eye with the target at range. They accomplish this through zoom by utilizing a set of lenses inside the scope. The scope’s positioning can be adapted for the consideration of different environmental factors like wind and elevation to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes and optics have about eleven parts which are located inside and outside of the optic. These scope parts include the rifle scope’s body, lenses, elevation dials or turrets, objective focus rings, and other elements. See all eleven parts of optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the optimal type of rifle scope is based around what type of shooting you plan on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are small
- Experienced shooters who recognize their target “hold over” and also “lead” equations for their long guns
- Shooters who do not mind the reticle is bigger and takes up more visual sight room than a SFP reticle
Second Focal Plane Scope Info
Second focal plane optics (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away types of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots occur within much shorter ranges and spaces
- Shooters who select a clearer optic picture without room used up by the larger size FFP reticle
Optic Zoom
The quantity of zoom a scope offers 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 Scopes
A single power rifle scope uses 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 type of scope can not adjust given that it is a fixed power scope.
About Adjustable Power Lens Rifle Glass
Variable power rifle scopes use enhanced power. The power change is performed by using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Scopes
Here are some advised scope powers and the ranges where they may be successfully used. Remember that high magnification scopes will not be as practical as lower powered scopes since increased zoom can be a negative thing in certain situations. The exact same idea relates to extended distances where the shooter needs to have enough power to see precisely where to best aim the rifle.
About Optic Lens Covering
All current rifle scope and optic lenses are layered. Lens finishing can be a crucial element of a rifle system when looking at high end rifle optics and scope systems.
HD Versus ED Optic Lens Coatings
Some glass suppliers additionally use “HD” or high-definition lens coatings that apply various processes, components, polarizations, and chemicals to extract separate colors and viewable target definition through the lens. This HD finishing is frequently used with higher density lens glass which brings down light’s capability to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be visible around items with hard outlines as light hits the object from specific angles.
Info on Single Coating Versus Multi-Coating
Various scope lenses can even have different coverings applied to them. All lenses typically have at least some kind of treatment or finish 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 becomes part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in numerous types of environments, degrees of light (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it.
Some scope manufacturers similarly make it a point to specify if their optic lenses are coated or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Anti-water Lens Coverings
Water on a scope’s lens does not help with retaining a clear sight picture through an optic in any way. Many top of the line or premium scope manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. 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 H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Glass Mounting Alternatives
Mounting options for scopes can be found in a couple of options. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally can be found in quick release variations which use manual levers which enable rifle shooters to rapidly mount and remove the scopes.
Hex Key Scope Ring Mounting Solutions
Basic, clamp-on style mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mount rails on rifles. These styles of scope mounts use double independent rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are designed for far away accuracy shooting. This kind of scope mount is effective for rifles which need to have a long lasting, rock solid mount which will not move no matter just how much the scope is moved about or jarring the rifle takes. These are the design of mounts you want for a devoted optics setup on a far away scouting or tournament rifle that will pretty much never need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount screws to keep the hex screw threads from wiggling out after they are mounted firmly in position. An example of these mounting rings are the 30mm style made by Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly attach and detach 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 are convenient for long guns which are transported a lot, to remove the optic from the rifle for protection, or for scopes which are used in between numerous rifles.
Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can wreck a day of shooting and your expensive optic by triggering fogging and producing residue within the scope tube. Many optics prevent humidity from getting in the scope tube with a system of sealing O-rings which are waterproof. Typically, these water resistant optics can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample wetness avoidance for basic use rifles for hunting and sporting purposes, 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 rifle.
Rifle Glass Gas Purging
Another part of avoiding the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the glass is less affected by climate shifts and pressure differences from the external environment which might potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
