Info About Scopes
Rifle scopes enable you to precisely align a rifle at various targets by aligning your eye with the target at range. They accomplish this through zoom using a series of lenses within the scope. The scope’s positioning can be adapted for consideration of various natural considerations like wind and elevation increases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based upon the sight picture you are seeing with the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle optics have around 11 parts which are arranged internally and on the exterior of the scope. These parts consist of the rifle scope’s body, lenses, modification dials or turrets, focus rings, and other parts. Learn about the eleven parts of rifle scopes.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the optimal type of rifle glass is based around what type of shooting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This induces the reticle to increase in size based on the amount of zoom being used. The outcome is that the reticle measurements are the same at the enhanced range as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at one hundred yards by using 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are small
- Experienced shooters who understand their target “hold over” as well as “lead” correlations for their firearms
- Shooters who don’t mind the reticle is enlarged and occupies more visual sight area than a SFP reticle
Second Focal Plane Optic Info
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots happen within shorter proximities and ranges
- Shooters who want a clearer optic picture with less space used up by the enlarged FFP reticle
Rifle Scope Magnification
The quantity of scope zoom you need on your optic depends upon the kind of shooting you want to do. Practically every kind of rifle optic gives some amount of magnification. The amount of magnification a scope supplies is established by the size, density, and curves of the lens glass inside of the rifle optic. The zoom of the optic is the “power” of the opic. This denotes what the shooter is aiming at through the scope is amplified times the power element of what can normally be seen by human eyes.
Fixed Power Lens Rifle Glass
A single power rifle scope and optic uses a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not change because it is a fixed power optic.
Info on Variable Power Lens Scopes
Variable power rifle scopes have adjustable power. It will note the magnification amount in a configuration like 2-10×32. These numbers mean the zoom of the scope can be adjusted between 2x and 10x power. This also includes the powers in-between 2 and 10. The power manipulation is accomplished using the power ring part of the scope near the back of the scope by the eye bell piece.
Power Levels and Range
Here are some recommended scope power settings and the distances where they could be successfully used. Keep in mind that high magnification scopes and optics will not be as practical as lower magnification level glass because excessive magnification can be a bad thing. The same relates to longer distances where the shooter needs adequate power to see where to best aim the rifle.
Details on Rifle Scope Lens Finish
All contemporary rifle optic lenses are layered. There are various types and qualities of glass finishes. When considering high end rifle targeting units, Lens covering can be a very important element of defining the capability of the rifle. The lenses are among the most critical components of the scope since they are what your eye sees through while sighting a rifle in on the point of impact. The covering on the lenses protects the lens exterior and even assists with anti glare from refracted daylight and color visibility.
ED Versus HD Scopes
Some rifle scope manufacturers will also use “HD” or high-def lense finishes which employ different processes, elements, polarizations, and chemical applications to extract numerous colors and viewable target definition through the lens. This high-def coating is frequently used with greater density lens glass which decreases light’s ability to refract through the lens glass. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration is often visible over things with well defined shapes as light hits the object from various angles.
Single Finish Versus Multi-Coating for Rifle Scopes
Different optic lenses can likewise have different coverings applied to them. All lenses typically have at least some type of treatment or finish applied 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 enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope manufacturer and just how much you spent on it. Both are indicators of the lens quality.
Some scope manufacturers also make it a point to define if their optic lenses are layered or “multi” coated. This suggests the lens has several treatments applied to the surfaces. If a lens receives numerous treatments, it can establish that a company is taking several steps to fight different environmental factors like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This additionally does not necessarily imply the multi-coated lens is better than a single covered lens. Being “much better” hinges on the maker’s lens treatment techniques and the quality of materials used in developing the rifle scope.
Anti-water Lens Finishing
Water on a scope’s lens does not improve keeping a clear sight picture through an optic whatsoever. Lots of top of the line and premium scope manufacturers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It deals with the surface of the Steiner optic lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Choices for Installing Optics on Firearms
Mounting approaches for scopes can be found in a couple of options. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also normally are made in quick release versions which use throw levers which permit rifle shooters to quickly install and remove the scopes.
Hex Key Scope Rings
Standard, clamp style mounting scope rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use double detached rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are designed for far away precision shooting. This form of scope mount is effective for rifle systems which are in need of a resilient, unfailing mount which will not shift no matter just how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a devoted optics system on a long distance hunting or competition long gun that will pretty much never need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to keep the hex screws from backing out after they are installed securely in position. An example of these rings are the 30mm type from Vortex Optics. The set generally costs around $200 USD
Optic Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, several scopes can often be switched out on the range. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping accuracy. These kinds of mounts come in convenient for rifles which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are chosen for use in between numerous rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It typically costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day of shooting and your costly optic by bringing about fogging and creating residue inside of the scope tube. Many scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
About Rifle Scope Tube Gas Purging
Another part of preventing the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the optic is less impacted by temp changes and pressure variations from the external environment which might possibly permit water vapor to permeate 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.
