Rifle scopes allow you to exactly align a rifle at various targets by lining up your eye with the target at range. They do this through magnifying the target using a series of lenses inside the scope. The scope’s positioning can be adapted to take into account various environmental factors like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the target. Many modern rifle scopes and optics have about 11 parts which are arranged inside and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other components. See all eleven parts of an optic.
The Types 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 optic is based on what type of shooting you plan to do.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who recognize their target “hold over” plus “lead” equations for their weapon
- Shooters who don’t mind the reticle is enlarged and occupies more visual sight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane glass (SFP) come with the reticle behind the magnifying lens. This triggers the reticle to stay at the same size in connection with the quantity of zoom being used. The end result is that the reticle dimensions change based upon the zoom chosen to shoot over greater distances since the reticle markings present various increments which change with the magnification level. 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 measurement. These particular types of scopes work for:
- Far away forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots take place within much shorter ranges and spaces
- Shooters who like a clearer optic sight picture without room used up by the larger sized FFP reticle
About Rifle Optic Magnification
The quantity of magnification a scope provides is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Rifle Glass
A single power rifle optic or scope will have a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not adjust since it is fixed.
Variable Power Lens Optic Details
Variable power rifle scopes can be changed between magnification power levels. It will list the zoom level in a configuration like 2-10×32. These numbers suggest the zoom of the scope can be changed between 2x and 10x power. This always includes the powers in-between 2 and 10. The power manipulation is accomplished by making use of the power ring part of the scope near the back of the scope by the eye bell piece.
The Power Level and Range Correlation of Optics
Here are some advised scope powers and the distances where they may be efficiently used. High power rifle scope glass will not be as efficient as lower powered scopes due to the fact that too much magnification can be a bad thing. The same goes for longer distances where the shooter needs to have increased power to see exactly where to best aim the rifle.
Rifle Optic Lens Finishing
All modern rifle optic and scope lenses are layered. Lens coating can be an important aspect of a shooting platform when looking at high end rifle optics and scope systems.
Info on Scope Lens Coatings – HD Versus ED
Some rifle scope producers even use “HD” or high-def lens finishings that take advantage of various processes, components, chemicals, and polarizations to extract separate color ranges and viewable target visibility through the lens. This high-definition coating is normally used with increased density lens glass which brings down light’s capability to refract by means of the lens glass. Some scope vendors use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be obvious around objects with hard outlines as light hits the object from specific angles.
Info on Single Finishing Versus Multi-Coating
Various optic lenses can likewise have various coverings applied to them. All lenses generally have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope developer and how much you spent paying for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope manufacturers likewise make it a point to define if their optic lenses are layered or “multi” covered. This indicates the lens has multiple treatments applied to the surfaces. If a lens receives multiple treatments, it can indicate that a manufacturer is taking several actions to combat various natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This also does not always indicate the multi-coated lens will perform better than a single covered lens. Being “much better” depends upon the maker’s lens treatment technology and the quality of materials used in building the rifle optic.
Anti-water Optic Lens Finishing
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Many top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic coating.
Choices for Installing Optics on Firearms
Installing approaches for scopes are available in a few choices. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also generally can be found in quick release variations which use throw levers which allow rifle shooters to quickly mount and remove the optics.
Hex Key Rifle Scope Ring Mounts
Basic, clamp type mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mount rails on the tops of rifles. These types of scope mounts use two detached rings to support the optic, and are made from 7075 T6 billet aluminum which are manufactured for far away accuracy shooting. This type of scope mount is great for rifles which need to have a durable, rock solid mount which will not change regardless of how much the scope is moved about or abuse the rifle takes. These are the design of mounts you want for a specialized optics setup on a reach out and touch someone scouting or competition rifle which will hardly ever need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on screws to protect against the hex screw threads from backing out after they are mounted firmly in place. An example of these rings are the 30mm type made by the Vortex Optics company. The set usually costs around $200 USD
Rifle Glass Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be swapped out if they all use a similar designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving accuracy. These types of mounts come in convenient for rifles which are transported a lot, to take off the glass from the rifle for protection, or for optics which are employed between several rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
What to Know About Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can spoil a day on the range and your expensive optic by resulting in fogging and producing residue inside of the scope tube. Many scopes prevent wetness from going into the optical tube with a series of sealing O-rings which are water resistant. Typically, these scopes can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness prevention for basic use rifles, unless you intend on taking your rifle boating and are worried about the scope still functioning if it falls overboard and you can still rescue the gun.
Gas Purged Rifle Optic Tubes
Another element of avoiding the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the scope is less impacted by temperature changes and pressure distinctions 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 look for.
