Info Glass
Rifle scopes permit you to specifically align a rifle at different targets by lining up your eye with the target at range. They do this through magnification by using a set of lenses within the scope. The scope’s positioning can be adjusted for consideration of numerous natural things like wind and elevation increases to account 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 via the optic as you align the scope’s crosshair or reticle with the target. Most modern-day rifle scopes and optics have about eleven parts which are arranged internally and externally on the scope. These optic pieces include the rifle scope’s body, lenses, modification turrets, focus rings, and other elements. See all eleven parts of scopes.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane a scope has determines where the reticle or crosshair is located in connection with the optic’s magnifying adjustments. It simply implies the reticle is situated behind or before the magnification lens of the scope. Picking the most beneficial style of rifle optic is based on what form of hunting or shooting you intend on undertaking.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This triggers the reticle to increase in size based upon the extent of zoom being used. The result is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. For example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the exact same tick at one hundred yards using 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are low
- Experienced shooters who know their aim point “hold over” as well as “lead” relationships for their weapon
- Shooters who don’t mind the reticle is bigger and occupies more visual sight area than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Long distance types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots occur within shorter proximities and ranges
- Shooters who choose a clearer optic picture without space used up by the bigger FFP reticle
Zoom for Rifle Glass
The measure of scope magnification you need on your optic is based on the form of shooting you wish to do. Pretty much every style of rifle optic delivers some amount of zoom. The level of zoom a scope gives is identified by the size, density, and curvatures of the lens glass inside of the rifle scope. The magnification of the optic is the “power” of the scope. This suggests what the shooter is looking at through the scope is magnified times the power aspect of what can normally be seen by human eyes.
Fixed Single Power Lens Rifle Glass
A single power rifle optic and scope will have 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 optic can not change because it is a fixed power scope.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes use enhanced power. The power adjustment is performed by using the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range
Here are some advised scope power levels and the ranges where they may be successfully used. Remember that high magnification glass will not be as effective as lower magnification level glass because increased magnification can be a bad thing. The same concept applies to extended distances where the shooter needs to have adequate power to see where to properly aim the rifle at the target.
Info on Optic Lens Finishing
All modern rifle glass lenses are covered. Lens finish can be a significant aspect of a shooting platform when considering high end rifle optics and scope equipment.
ED Versus HD Rifle Optics
Some rifle scope makers additionally use “HD” or high-def glass coverings that use various procedures, polarizations, chemicals, and elements to enhance different colors and viewable target visibility through the lens. This high-def covering is normally used with more costly, high density lens glass which decreases light’s ability to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be obvious over objects with hard shapes as light hits the item from particular angles.
Single Scope Lens Finishing Versus Multi-Coating
Different optic lenses can even have different finishings applied to them. All lenses normally have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic assembly. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in lots of types of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope manufacturer and just how much you spent paying for it. The scope’s maker and cost are indications of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are coated or “multi” coated. Being “much better” depends on the maker’s lens treatment technology and the quality of products used in developing the rifle scope.
Details on Hydrophobic Covering
Water on a lens doesn’t support preserving a clear sight picture through an optic in any way. Numerous top of the line and high-end scope manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the exterior of the Steiner optic lens so the H2O molecules can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Scopes on Firearms
Mounting options for scopes can be found in a couple of choices. There are the basic scope rings which are individually installed 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 versions which use throw levers which enable rifle operators to quickly install and remove the scopes.
Hex Key Scope Ring Mounting Solutions
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope mount is excellent for rifles which require a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
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 comparable design mount, multiple scopes can also be switched out on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top style 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 retaining precision. These kinds of mounts are useful and beneficial for shooting platforms which are transported a lot, to remove the optic from the rifle for protection, or for scopes which are used in between a number of rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your costly optic by causing fogging and creating residue inside of the scope tube. Most scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Optic Tubes
Another component of avoiding the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the optic is less impacted by temperature alterations and pressure distinctions from the outdoor environment which might potentially enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
