Rifle scopes permit you to precisely aim a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through zoom by using a series of lenses inside the scope. The scope’s alignment can be adjusted for consideration of numerous ecological factors like wind and elevation decreases to account for bullet drop.
The scope’s function is to understand exactly where the bullet will land based on the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended target. Many modern-day rifle scopes and optics have about 11 parts which are located within and outside of the scope. These parts include the rifle scope’s body, lenses, adjustment dials, focus rings, and other parts. See all eleven parts of a scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the finest type of rifle glass is based around what type of shooting you plan to do.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are small
- Experienced shooters who know their target “hold over” and also “lead” equations for their rifles
- Shooters who do not mind the reticle is enlarged and takes up more visual sight room than a SFP reticle
Second Focal Plane Glass Info
Second focal plane optics (SFP) feature the reticle behind the zoom lens. This induces the reticle to stay at the exact same size in connection with the quantity of magnification being used. The effect is that the reticle dimensions shift based upon the zoom applied to shoot over longer ranges since the reticle markings present various increments which change with the magnification. 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. These particular kinds of glass work for:
- Long distance types of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots occur within shorter ranges and proximities
- Shooters who choose a clearer optic picture without area used up by the bigger FFP reticle
Ins and Outs of Rifle Scope Zoom
The extent of scope zoom you require is based on the kind of shooting you intend to do. Just about every style of rifle glass delivers some degree of zoom. The level of zoom a scope delivers is established by the size, density, and curves of the lens glass within the rifle optic. The magnification level of the optic is the “power” of the opic. This indicates what the shooter is aiming at through the scope is amplified times the power aspect of what can usually be seen by human eyes.
Fixed Power Lens Scope Facts
A single power rifle optic and scope will have 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 magnification of this type of scope can not change because it is a fixed power optic.
Variable Power Lens Optics
Variable power rifle scopes use enhanced power. The power change is accomplished by making use of the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some recommended scope powers and the distances where they could be successfully used. Keep in mind that higher magnification optics will not be as practical as lower magnification level scope and optics because excessive zoom can be a detractor. The exact same idea applies to extended distances where the shooter needs to have sufficient power to see where to properly aim the rifle at the target.
About Lens Coverings
All contemporary rifle optic lenses are coated. There are different types and qualities of glass lens coverings. When researching luxury rifle optics and scope units, Lens finish can be a significant aspect of a rifle. The glass lenses are one of the most key components of the glass because they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses protects the lens surface and improves anti glare from excess natural light and color visibility.
HD Versus ED Lenses
Some scope manufacturers also use “HD” or high-definition lens finishes which use different methods, components, chemicals, and polarizations to draw out various colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finish Versus Multi-Coating
Various optic lenses can also have various coverings used to them. All lenses generally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” coated. This means the lens has several treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can show that a company is taking several actions to fight various natural aspects like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This additionally does not always indicate the multi-coated lens is better than a single coated lens. Being “much better” is dependent on the producer’s lens treatment innovation and the quality of glass used in building the rifle scope.
Details on Hydrophobic Coating
Water on a scope’s lens does not improve retaining a clear sight picture through an optic at all. Numerous top of the line or high-end scope makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the exterior of the Steiner glass lens so the H2O molecules can not bind to it or develop surface tension. The outcome is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Rifle Scope Installation Choices
Installing solutions for scopes come in a few choices. There are the basic scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally can be found in quick release versions which use throw levers which enable rifle operators to rapidly mount and remove the optics.
Hex Key Rifle Glass Ring Mounts
Standard, clamp-on style mounting optic rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These types of scope mounts use two individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are created for long distance precision shooting. This type of scope mount is ideal for rifles which need a resilient, unfailing mount which will not move regardless of how much the scope is moved about or abuse the rifle takes. These are the type of mounts you really want to have for a devoted scope system on a reach out and touch someone hunting or interdiction rifle which will almost never need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to prevent the hex screw threads from backing out after they are installed securely in position. An example of these mounting rings are the 30mm type made by the Vortex Optics company. The set generally costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and attach it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible style mount. These types of mounts come in handy for rifles which are carried a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between numerous rifles.
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope tube. Most scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Details on Rifle Scope Tube Gas Purging
Another component of avoiding the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the optic is less altered by temperature alterations and pressure variations from the outdoor 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 decent rifle scope to seek out.
