Rifle scopes allow you to precisely aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnifying the target by using a set of lenses inside the scope. The scope’s positioning can be adjusted to account for different natural aspects like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the intended target. Most modern rifle optics have around eleven parts which are located within and outside of the scope. These parts consist of the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other components. Learn about the eleven parts of rifle glass.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has identifies where the reticle or crosshair lies in connection with the scopes zoom. It actually implies the reticle is located behind or in front of the magnifying lens of the scope. Picking out the most desired type of rifle glass is dependent on what form of hunting or shooting you intend on doing.
First Focal Plane Scope Facts
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are minimal
- Experienced shooters who know their target “hold over” and also “lead” equations for their weapon
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Second Focal Plane Optic Info
Second focal plane optics (SFP) include the reticle behind the magnification lens. This induces the reticle to remain at the same dimensions in connection with the level of magnification being used. The effect is that the reticle dimensions adapt based on the zoom employed to shoot over greater ranges since the markings represent distinct increments which fluctuate with the zoom level. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick. These particular styles of glass work for:
- Long distance forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots take place within shorter spaces and ranges
- Shooters who would like a clearer optic sight picture without room used up by the enlarged FFP reticle
Magnification for Scopes
The measure of scope magnification you require depends on the sort of shooting you choose to do. Almost every type of rifle scope delivers some degree of zoom. The amount of magnification a scope offers is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the optic is the “power” of the opic. This signifies what the shooter is looking at through the scope is magnified times the power factor of what can normally be seen by human eyes.
Fixed Power Lens Rifle Scopes
A single power rifle optic will have a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not adjust given that it is set from the factory.
Variable Power Lens Glass Details
Variable power rifle scopes can be adjusted between magnification levels. These types of scopes will note the zoom degree in a configuration such as 2-10×32. These numbers mean the zoom of the scope can be adjusted between 2x and 10x power. This always involves the power levels in-between 2 and 10. The power shift is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Optics
Here are some suggested scope power settings and the ranges where they could be effectively used. Consider that higher power scopes and optics will not be as practical as lower powered scopes due to the fact that excessive magnification can be a negative thing in certain situations. The same idea relates to extended distances where the shooter needs to have sufficient power to see where to properly aim the rifle.
Info on Lens Coverings
All contemporary rifle scope lenses are covered in special coatings. There are various types and qualities of finishes. Lens finish can be an important element of a rifle when contemplating high end rifle optics and targeting equipment. The glass lenses are one of the most critical pieces of the optic as they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses protects the lens surface and also improves anti glare from excess direct sunlight and color presence.
HD Versus ED Lenses
Some rifle scope manufacturers will also use “HD” or high-definition glass finishes which employ different procedures, polarizations, aspects, and chemicals to extract different colors and viewable target definition through the lens. This high-def finishing is commonly used with more costly, high density lens glass which lowers light’s capability to refract through the lens glass. Some scope producers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration can be visible over items with hard edges and outlines as light hits the item from various angles.
About Single Coating Versus Multi-Coating
Different optic lenses can even have various finishings applied to them. All lenses normally 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 finely tuned optic. It requires a coating to be applied to it so that it will be efficiently functional in numerous types of environments, degrees of light (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Anti-water Lens Finishes
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic finishing.
Alternatives for Installing Rifle Scopes on Firearms
Mounting options for scopes can be found in a couple of choices. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually are made in quick release variations which use manual levers which enable rifle operators to quickly install and dismount the optics.
Rifle Glass Mounts with Hex Key Rings
Basic, clamp-on type mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mount rails on rifles. These kinds of scope mounts use a pair of independent rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are designed for long distance accuracy shooting. This kind of scope mount is exceptional for rifles which need a long lasting, unfailing mount which will not change despite how much the scope is moved or jarring the rifle takes. These are the type of mounts you want for a faithful scope system on a long distance hunting or interdiction long gun which will almost never need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount screws to prevent the hex screws from backing out after they are mounted tightly in place. An example of these rings are the 30mm style from the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Scope Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle. If they all use a comparable style mount, multiple scopes can also be switched out. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining accuracy. These types of mounts are useful and beneficial for rifles which are transported a lot, to take off the scope glass from the rifle for protection, or for sight systems which are employed between several rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle glass can destroy a day on the range and your expensive optic by inducing fogging and making residue inside of the scope’s tube. The majority of scopes protect against wetness from going into the scope tube with a system of sealing O-rings which are water resistant. Typically, these water-resistant optics can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough wetness prevention for conventional use rifles, unless you plan on taking your rifle on your motorboat and are concerned about the optic still performing if it is submerged in water and you can still rescue the rifle.
Scope Gas Purging
Another element of avoiding the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is currently occupied by the gas, the glass is less impacted by temperature level shifts and pressure variations from the external environment which might possibly allow water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
