Info Optics
Rifle scopes permit you to specifically align a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnifying the target by utilizing a series of lenses inside the scope. The scope’s positioning can be dialed in to account for different ecological factors like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle optics have around eleven parts which are located within and outside of the optic. These scope parts include the rifle scope’s body, lenses, modification dials, focus rings, and other elements. See all eleven parts of a scope.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane an optic has determines where the reticle or crosshair is located in relation to the optic’s zoom. It actually means the reticle is situated behind or before the magnifying lens of the optic. Picking the very best sort of rifle optic depends on what variety of hunting or shooting you plan on undertaking.
First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are low
- Experienced shooters who know their aim point “hold over” as well as “lead” correlations for their long gun
- Shooters who do not mind the reticle is enlarged and takes up more visual sight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane glass (SFP) come with the reticle behind the magnifying lens. This causes the reticle to remain at the exact same scale in connection with the amount of magnification being used. The result is that the reticle measurements evolve based upon the zoom chosen to shoot over greater ranges considering that the markings represent various increments which vary with the magnification. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These particular styles of scopes work for:
- Far away types of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots take place within shorter ranges and distances
- Shooters who select a clearer optic sight picture with less space taken up by the enlarged FFP reticle
Details on Rifle Scope Magnification
The level of scope magnification you require depends upon the type of shooting you would like to do. Practically every type of rifle optic gives some amount of magnification. The amount of zoom a scope gives is identified by the diameter, density, and curves of the lens glass inside of the rifle scope. The zoom of the optic is the “power” of the glass. This means what the shooter is aiming at through the scope is amplified times the power aspect of what can usually be seen by human eyes.
Info About Single Power Lens Rifle Scopes
A single power rifle optic or scope comes with 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 optic can not adjust considering that it is set from the factory.
About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes use variable power levels. The power change is achieved 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 Optics
Here are some advised scope power settings and the ranges where they could be effectively used. Keep in mind that higher magnification glass will not be as practical as lower magnification level scopes because increased zoom can be a bad thing. The exact same concept relates to extended distances where the shooter needs adequate power to see exactly where to properly aim the rifle.
Lens Finish for Rifle Scopes
All modern-day rifle scope and optic lenses are layered. Lens finishing is an essential aspect of a shooting platform when considering high end rifle optics and scope systems.
ED Versus HD Optics
Some scope brands also use “HD” or high-definition lens coverings which use different methods, components, polarizations, and chemicals to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Finish Versus Multi-Coating for Rifle Glass
Different optic lenses can also have various finishes applied to them. All lenses typically have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It needs to have a coating applied to it so that it will be optimally usable in many kinds of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and improving 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 layered lens depends upon the scope producer and the amount you spent for it. Both the manufacturer and amount are signs of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
Anti-water Lens Covering
Water on a scope’s lens does not support keeping a clear sight picture through an optic at all. Lots of top of the line or premium optic producers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the surface area of the Steiner glass lens so the H2O particles can not bind to it or produce 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 Scopes on Long Guns
Mounting solutions for scopes can be found in a few options. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also generally can be found in quick release versions which use toss levers which permit rifle shooters to rapidly install and remove the scopes.
Hex Key Rifle Glass Rings
Standard, clamp design mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use a pair of separate rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are created for long distance precision shooting. This kind of scope mount is good for rifles which are in need of a long lasting, hard use mount which will not move regardless of how much the scope is moved about or abuse the rifle takes. These are the style of mounts you want for a devoted optics system on a long distance hunting or interdiction rifle that will pretty much never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used to keep the hex screw threads from backing out after they are mounted tightly in position. An example of these mounting rings are the 30mm type made by the Vortex Optics company. The set normally costs around $200 USD
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be switched out if they all use a compatible style mount. These types of mounts are convenient for long guns which are transported a lot, to swap out the optic from the rifle for protection, or for optics which are used in between several rifles.
Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your expensive optic by causing fogging and creating residue inside of the scope tube. A lot of scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Glass Tubes
Another element of preventing the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the optic is less affected by temperature alterations and pressure distinctions from the external environment which could potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
