What You Need to Know About Scopes
Rifle scopes permit you to exactly aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom by using a series of lenses within the scope. The scope’s alignment can be adjusted for the consideration of different ecological factors like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based upon 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. Many contemporary rifle scopes have about 11 parts which are arranged within and outside of the scope. These parts include the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other elements. See all eleven parts of an optic.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the perfect type of rifle glass depends on what type of shooting you plan to do.
Info on First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who know their aim point “hold over” and “lead” correlations for their weapon
- Shooters who do not mind the reticle is enlarged and requires more visual sight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. This triggers the reticle to stay at the exact same size relative to the level of magnification being used. The result is that the reticle dimensions change based upon the zoom chosen to shoot over greater ranges given that the reticle measurements present distinct increments which differ with the zoom. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular kinds of glass are beneficial for:
- Long distance kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and spaces
- Shooters who would like a clearer optic sight picture without space used up by the bigger FFP reticle
About Rifle Optic Zoom
The measure of scope magnification you need on your scope depends upon the kind of shooting you desire to do. Pretty much every type of rifle optic delivers some amount of zoom. The amount of zoom a scope provides is identified by the dimension, density, and curvatures of the lenses within the rifle scope. The magnification of the scope is the “power” of the glass. This implies what the shooter is checking out through the scope is magnified times the power element of what can typically be seen by human eyes.
Fixed Single Power Lens Rifle Glass Facts
A single power rifle optic or scope uses a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not change because it is a fixed power optic.
Adjustable Power Lens Glass
Variable power rifle scopes use enhanced power. The power change is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Scopes
Here are some suggested scope powers and the ranges where they may be effectively used. High power optics will not be as efficient as lower magnification scopes considering that too much magnification can be a bad thing. The exact same idea applies to extended distances where the shooter needs to have sufficient power to see precisely where to best aim the rifle.
Info on Lens Finish
All present day rifle optic and scope lenses are layered. Lens coating is an important element of a rifle when buying high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope manufacturers also use “HD” or high-definition lens finishes which use different techniques, components, chemicals, and polarizations to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Info on Single Finish Versus Multi-Coating
Various optic lenses can likewise have various finishes used to them. All lenses typically have at least some type of treatment or coating applied to them before being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope producer and how much you spent on it. Both are signs of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the maker’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Hydrophobic Lens Coatings
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Many top of the line and military grade scope companies will coat their lenses with a hydrophobic or hydrophilic anti-water finish.
Options for Mounting Scopes on Firearms
Mounting approaches for scopes can be found in a couple of choices. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also normally can be found in quick release variations which use toss levers which allow rifle shooters to quickly mount and dismount the optics.
Hex Key Rifle Optic Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope mount is fine for rifles which require a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be switched out if they all use a similar style mount. These types of mounts are convenient for rifle platforms which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles.
Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. Many scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Info Around Rifle Optic Tube Gas Purging
Another part of avoiding the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the optic is less influenced by temperature level alterations and pressure differences from the outdoor environment which may potentially 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 seek out.
