What You Need to Know About Rifle Scopes
Rifle scopes allow you to precisely aim a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through zoom by employing a series of lenses within the scope. The scope’s alignment can be adjusted to account for various environmental considerations like wind speed and elevation to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the target. The majority of modern-day rifle optics have about eleven parts which are arranged inside and outside of the optic. These parts include the rifle scope’s body, lenses, elevation dials or turrets, focus rings, and other parts. Learn about the eleven parts of rifle optics.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has establishes where the reticle or crosshair is located relative to the scopes magnifying adjustments. It actually means the reticle is situated behind or before the magnifying lens of the scope. Selecting the best style of rifle scope is based on what kind of shooting you plan on doing.
About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are small
- Experienced shooters who have an idea for their target “hold over” as well as “lead” equations for their rifles
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight room than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle behind the zoom 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 measurement.
- Long distance styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots happen within much shorter proximities and ranges
- Shooters who desire a clearer optic sight picture with less room used up by the larger sized FFP reticle
About Rifle Scope Magnification
The amount 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 Single Power Lens Rifle Glass
A single power rifle scope and optic uses a zoom number designator like 4×32. This suggests 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 since it is a fixed power scope.
About Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be changed between magnification levels. These types of scopes will note the zoom degree in a configuration like 2-10×32. These numbers suggest the magnification of the scope could be changed in between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power manipulation is achieved by employing the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Glass Power and Range Correlation
Here are some suggested scope power settings and the ranges where they can be effectively used. High power glass will not be as beneficial as lower powered scopes given that too much magnification can be a negative aspect depending on your shooting distance. The same idea applies to longer ranges where the shooter needs to have increased power to see exactly where to best aim the rifle at the target.
Lens Finishing for Rifle Glass
All present day rifle scope lenses are layered. Lens coating is a significant element of a shooting platform when buying high end rifle optics and scope setups.
Details on Rifle Optic Lens Coatings – HD Versus ED
Some rifle scope companies additionally use “HD” or high-def glass coverings that take advantage of various processes, elements, polarizations, and chemicals to draw out a wide range of colors and viewable definition through the lens. This HD finish is often used with increased density lens glass which decreases light’s capability to refract by means of the lens glass. Some scope brands use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration is often obvious over items with well defined shapes as light hits the object from various angles.
Single Covering Versus Multi-Coating
Various optic lenses can also have various finishes used to them. All lenses generally have at least some type of treatment or finishing used to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can safeguard the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends on the scope maker and how much you spent on it. The scope’s maker and cost are indications of the lens quality.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” coated. This implies the lens has had several treatments applied to them. If a lens gets several treatments, it can indicate that a company is taking several actions to combat different environmental factors like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This also doesn’t always indicate the multi-coated lens is much better than a single covered lens. Being “much better” hinges on the manufacturer’s lens treatment technology and the quality of products used in building the rifle glass.
Hydrophobic Finish for Rifle Optics
Water on a scope lens does not help with maintaining a clear sight picture through a scope at all. Lots of top of the line or premium optic makers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the surface area of the Steiner glass lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Scope Mounting Alternatives
Mounting approaches for scopes come in a few options. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also typically are made in quick release versions which use throw levers which allow rifle shooters to quickly install and dismount the scope.
Glass Mounts with Hex Key Rings
Standard, clamp design 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 different rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This type of scope mount is perfect for rifles which need a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Scope Ring Mounts
These kinds of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. If they all use a similar design mount, several scopes can often be switched in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely 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 retaining accuracy. These kinds of mounts are useful and practical for shooting platforms which are shipped a lot, to remove the optic from the rifle for protection, or for scopes which are utilized between a number of rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It normally costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your expensive optic by triggering fogging and generating residue within the scope’s tube. Many scopes protect against humidity from getting in the scope tube with a system of sealing O-rings which are water resistant. Generally, these water resistant optics can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient moisture prevention for basic use rifles, unless you anticipate taking your rifle on boats and are concerned about the scope still working if it is submerged in water and you can still retrieve the gun.
Scope Gas Purging
Another element of preventing the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the glass is less influenced by climate alterations and pressure distinctions from the external environment which might potentially permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
