All About Rifle Scopes
Rifle scopes enable you to exactly align a rifle at various targets by aligning your eye with the target over a range. They do this through magnifying the target by employing a set of lenses within the scope. The scope’s alignment can be adapted to take into account varied ecological considerations like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of modern rifle scopes have around eleven parts which are found within and externally on the optic. These scope parts include the rifle scope’s body, lenses, modification dials, objective focus rings, and other components. Learn about the eleven parts of glass.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane an optic has determines where the reticle or crosshair lies in relation to the optic’s zoom. It simply suggests the reticle is behind or ahead of the magnifying lens of the scope. Picking out the most effective form of rifle glass depends upon what form of shooting you intend on undertaking.
Info on First Focal Plane Glass
First focal plane optics (FFP) include the reticle ahead of the zoom lens. This triggers the reticle to increase in size based on the amount of zoom being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. For instance, one tick on a mil-dot reticle at 100 yards without any “zoom” is still the same tick at 100 yards using 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are small
- Experienced shooters who recognize their target “hold over” plus “lead” correlations for their firearms
- Shooters who do not mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle behind the magnifying lens. This induces the reticle to stay at the exact same size in relation to the quantity of zoom being used. The end result is that the reticle measurements adjust based upon the magnification used to shoot over longer ranges considering that the reticle markings represent various increments which vary with the magnification level. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular varieties of optics work for:
- Far away forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots occur within much shorter ranges and distances
- Shooters who like a clearer optic picture with less room used up by the larger size FFP reticle
Magnification for Rifle Scopes
The level of scope zoom you need depends upon the kind of shooting you want to do. Almost every kind of rifle glass offers some level of zoom. The quantity of magnification a scope provides is determined by the dimension, thickness, and curvatures of the lens glass within the rifle optic. The magnification of the optic is the “power” of the scope. This indicates what the shooter is looking at through the scope is amplified times the power element of what can generally be seen by human eyes.
Info on Single Power Lens Rifle Glass
A single power rifle scope uses a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not fluctuate since it is a fixed power scope.
About Variable Power Lens Glass
Variable power rifle scopes can be modified between magnified settings. The power change is performed by the power ring part of the scope near the back of the scope by the eye bell.
Rifle Glass Power and Ranges
Here are some advised scope powers and the distances where they can be successfully used. Consider that high magnification scopes and optics will not be as effective as lower magnification level scopes due to the fact that increased zoom can be a detractor. The same concept goes for longer distances where the shooter needs to have sufficient power to see exactly where to properly aim the rifle.
Details on Rifle Optic Lens Coating
All modern-day rifle scope lenses are coated. There are different types and qualities of glass lens coverings. When shopping for luxury rifle scope units, Lens covering can be an important element of defining the capability of the rifle. The lenses are one of the most essential parts of the optic because they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses shields the lens surface as well as improves anti glare capabilities from refracted daylight and color discernibility.
HD Versus ED Glass Lens Coatings
Some rifle scope producers even use “HD” or high-def glass finishes that use various procedures, chemicals, polarizations, and components to draw out different colors and viewable target definition through lenses. This HD finishing is typically used with increased density glass which reduces light’s opportunity to refract through the lens glass. Some scope suppliers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how certain colors are represented on the chroma spectrum and the chromatic 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 specific angles.
About Single Finishing Versus Multi-Coating
Different optic lenses can also have various coatings applied to them. All lenses usually have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic assembly. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a finishing applied to it so that it will be optimally functional in numerous types of environments, degrees of light (full VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope manufacturer and how much money you spent paying for it. Both the manufacturer and amount are signs of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in constructing the rifle scope.
What to Know About Anti-water Covering
Water on a scope’s lens does not support keeping a clear sight picture through a scope in any way. Numerous top of the line and premium 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 provides protection for the surface area of the Steiner optic lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Rifle Glass Installation Choices
Installing approaches for scopes are available in a couple of options. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various 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 scope.
Hex Key Scope Ring Mounting Solutions
Standard, clamp type mounting scope rings use hex head screws to install to the flattop design Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use double detached rings to support the optic, and are normally made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope mount is great for rifle systems which are in need of a resilient, rock solid mount which will not change regardless of just how much the scope is moved about or abuse the rifle takes. These are the design of mounts you should have for a devoted scope system on a far away hunting or interdiction firearm that will almost never need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount screws to stop the hex screws from backing out after they are installed tightly in place. An example of these rings are the 30mm style from the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and connect it to a different rifle. Multiple scopes can also be swapped out if they all use a similar style mount. These types of mounts are convenient for rifle platforms which are carried a lot, to swap out the optic from the rifle for protection, or for optics which are used between several rifles.
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your costly optic by causing fogging and producing residue inside of the scope tube. Many scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Glass Tubes
Another component of preventing the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the optic is less altered by climate alterations and pressure variations from the outside environment which could potentially allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
