What You Need to Know About Scopes
Rifle scopes enable you to exactly align a rifle at different targets by aligning your eye with the target over a range. They do this through magnification by employing a series of lenses within the scope. The scope’s positioning can be adjusted for the consideration of various environmental aspects like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes have around eleven parts which are found inside and on the exterior of the scope body. These parts include the rifle scope’s body, lenses, modification dials or turrets, focus rings, and other components. Learn about the eleven parts of rifle scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the best type of rifle glass is based around what type of shooting you plan to do.
About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are minimal
- Experienced shooters who recognize their target “hold over” plus “lead” correlations for their firearm
- Shooters who don’t mind the reticle is bigger and uses up more visual sight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. This triggers the reticle to remain at the same overall size relative to the quantity of zoom being used. The result is that the reticle dimensions alter based on the magnification chosen to shoot over lengthier distances considering the reticle markings represent different increments which differ with the magnification level. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular types of glass are handy for:
- Far away kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots take place within shorter ranges and spaces
- Shooters who want a clearer optic sight picture without area used up by the enlarged FFP reticle
Optic Zoom
The amount of zoom a scope supplies is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Rifle Optic Info
A single power rifle optic comes with a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not fluctuate considering that it is fixed.
Adjustable Power Lens Rifle Optic Details
Variable power rifle scopes have adjustable power. It will note the magnification degree in a format like 2-10×32. These numbers indicate the magnification of the scope could be adjusted in between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power shift is accomplished by applying the power ring part of the scope near the rear of the scope by the eye bell piece.
Power Levels and Range Correlations
Here are some advised scope power levels and the distances where they may be successfully used. Consider that high magnification scopes will not be as efficient as lower powered optics and scopes because excessive magnification can be a bad thing. The exact same idea applies to extended ranges where the shooter needs increased power to see where to best aim the rifle.
About Rifle Optic Lens Finishes
All contemporary rifle optic and scope lenses are layered. There are various types and qualities of lens finishes. Lens finish is an essential aspect of a rifle when considering high-end rifle optics and scope equipment. The lenses are among the most crucial components of the scope due to the fact that they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses protects the lens surface area and even assists with anti glare capabilities from refracted daylight and color visibility.
HD Versus ED Lens Coatings
Some optic makers also use “HD” or high-def lense coatings that apply different processes, aspects, rare earth compounds, and polarizations to enhance different colors and viewable target visibility through the lens. This HD coating is often used with more costly, high density glass which reduces light’s potential to refract through the lens glass. Some scope vendors use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration is often noticeable over objects with hard outlines as light hits the item from specific angles.
Single Coating Versus Multi-Coating for Rifle Glass
Different optic lenses can likewise have various finishings used to them. All lenses usually have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while minimizing 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 producer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are covered or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Anti-water 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 high-end optic makers will coat their lenses with a hydrophilic or hydrophobic anti-water covering.
Alternatives for Installing Scopes on Long Guns
Installing options for scopes are available in a few options. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also normally come in quick release variations which use toss levers which allow rifle operators to quickly install and remove the optics.
Rifle Scope Mounts with Hex Key Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope install is wonderful for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, multiple scopes can often be swapped on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping precision. These types of mounts come in convenient for rifles which are transferred between vehicles a lot, to remove the glass from the rifle for protection, or for scopes which are chosen for use in between multiple rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It normally costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can spoil a day of shooting and your highly-priced optic by inducing fogging and producing residue inside of the scope tube. The majority of 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 submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of humidity avoidance for common use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on your motorboat and are concerned about the optic still performing if it falls overboard and you can still salvage the gun.
Rifle Glass Gas Purging
Another part of preventing the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the glass is less impacted by temperature shifts and pressure variations from the outdoor environment which may potentially enable water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
