Rifle scopes enable you to exactly aim a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnification using a series of lenses inside the scope. The scope’s alignment can be adjusted for the consideration of different environmental considerations like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the target. Most modern rifle optics have around eleven parts which are arranged within and externally on the optic. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other parts. Learn about the eleven parts of optics.
About Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has identifies where the reticle or crosshair lies relative to the optic’s zoom. It actually implies the reticle is behind or ahead of the magnifying lens of the optic. Considering the most beneficial sort of rifle scope is based on what kind of hunting or shooting you intend on doing.
First Focal Plane Optic Details
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This induces the reticle to increase in size based upon the amount of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified range. For instance, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who have an idea for their target “hold over” plus “lead” correlations for their firearm
- Shooters who do not mind the reticle is bigger and requires more visual sight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Long distance types of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots happen within much shorter ranges and spaces
- Shooters who choose a clearer optic picture with less room used up by the bigger FFP reticle
Zoom for Rifle Glass
The amount of scope zoom you need on your scope depends upon the type of shooting you want to do. Almost every type of rifle optic offers some degree of magnification. The amount of zoom a scope provides is determined by the diameter, thickness, and curves of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the opic. This suggests what the shooter is looking at through the scope is amplified times the power element of what can normally be seen by human eyes.
Fixed Single Power Lens Optic Info
A single power rifle scope comes with a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not adjust because it is a fixed power scope.
Adjustable Power Lens Scopes
Variable power rifle scopes can be adjusted between magnification levels. These types of scopes will note the zoom degree in a format like 2-10×32. These numbers imply the zoom of the scope can be set between 2x and 10x power. This additionally utilizes the powers in-between 2 and 10. The power adjustment is accomplished by employing the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some suggested scope powers and the distances where they can be effectively used. Highly magnified rifle scope glass will not be as useful as lower magnification glass considering too much magnification can be a bad thing. The same concept goes for longer ranges where the shooter needs increased power to see precisely where to properly aim the rifle at the target.
Lens Coating for Rifle Optics
All current rifle glass lenses are layered. Lens finishing is an essential aspect of a shooting system when considering high end rifle optics and scope systems.
ED Versus HD Glass
Some rifle glass companies also use “HD” or high-definition lense coatings that use different procedures, polarizations, chemicals, and components to extract various colors and viewable definition through lenses. This high-def covering is often used with more costly high density lens glass which reduces light’s opportunity to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration is often obvious over things with well defined outlines as light hits the item from particular angles.
Single Finish Versus Multi-Coating for Rifle Optics
Various optic lenses can likewise have different coatings applied to them. All lenses generally have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are coated or “multi” coated. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Details on Anti-water Finishing
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic anti-water covering.
Options for Installing Rifle Glass on Long Guns
Mounting options for scopes are available 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 different types of mounts also usually are made in quick release variations which use manual levers which allow rifle shooters to quickly install and dismount the glass.
Hex Key Rifle Scope Ring Mounting Solutions
Basic, clamp style mounting optic rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These styles of scope mounts use two detached rings to support the scope, and are normally made from 7075 T6 billet aluminum which are made for long distance accuracy shooting. This kind of scope mount is great for rifle systems which require a long lasting, hard use mount which will not shift no matter how much the scope is moved about or abuse the rifle takes. These are the type of mounts you really want to have for a specialized scope setup on a far away scouting or interdiction rifle that will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used to stop the hex screws from backing out after they are mounted tightly in place. An example of these rings are the 30mm type made by the Vortex Optics brand. The set generally costs around $200 USD
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, a number of scopes can also be swapped out. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach nicely 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 preserving accuracy. These kinds of mounts are useful and convenient for rifles which are moved a lot, to remove the scope glass from the rifle for protection, or for sight systems which are utilized in between multiple rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
What to Know About Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. A lot of scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Glass Tubes
Another part of preventing the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the glass is less affected by temp changes and pressure distinctions from the external environment which could possibly allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
