Facts About Scopes
Rifle scopes enable you to specifically aim a rifle at different targets by lining up your eye with the target over a range. They do this through zoom by utilizing a set of lenses within the scope. The scope’s positioning can be adapted to account for different environmental elements like wind and elevation increases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the intended target. Most contemporary rifle optics have about eleven parts which are located internally and on the exterior 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 glass.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane a scope has identifies where the reticle or crosshair lies relative to the optic’s magnification. It simply indicates the reticle is behind or in front of the magnification lens of the optic. Selecting the most desired kind of rifle optic depends on what variety of hunting or shooting you anticipate undertaking.
First Focal Plane Optic Facts
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who understand their target “hold over” and “lead” equations for their rifles
- Shooters who do not mind the reticle is bigger and takes up more visual sight space than a SFP reticle
Second Focal Plane Scope Info
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick.
- Long distance styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots occur within shorter ranges and spaces
- Shooters who select a clearer optic picture with less space used up by the enlarged FFP reticle
Magnification for Glass
The measure of scope magnification you require depends upon the style of shooting you want to do. Pretty much every kind of rifle scope delivers some amount of magnification. The level of zoom a scope gives is established by the diameter, density, and curves of the lens glass inside of the rifle optic. The zoom of the optic is the “power” of the scope. This implies what the shooter is checking out through the scope is amplified times the power element of what can usually be seen by human eyes.
Fixed Power Lens Glass Info
A single power rifle optic and scope uses a zoom 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 scope.
About Adjustable Power Lens Optics
Variable power rifle scopes can be tweaked between magnified levels. The power change is achieved by using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Optics
Here are some advised scope power settings and the ranges where they can be effectively used. Always remember that higher magnification glass will not be as practical as lower powered scopes since excessive magnification can be a detractor. The exact same idea relates to longer distances where the shooter needs enough power to see exactly where to best aim the rifle at the target.
About Rifle Optic Lens Finishes
All state-of-the-art rifle optic lenses are covered. Lens covering can be an essential element of a rifle when considering high end rifle optics and scope equipment.
ED Versus HD Glass
Some scope makers likewise use “HD” or high-definition lens coverings which use various techniques, polarizations, chemicals, and aspects to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Rifle Scope Lens Single Finish Versus Multi-Coating
Various optic lenses can even have different finishings applied to them. All lenses normally have at least some kind of treatment or finishing applied to them before they are used in a rifle scope or optic assembly. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It needs to have a finishing put on it so that the lens will be efficiently usable in lots of kinds of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” covered. This suggests the lens has had multiple treatments applied to the surfaces. If a lens gets multiple treatments, it can show that a maker is taking multiple actions to fight various natural aspects like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic covering. This also does not necessarily imply the multi-coated lens will perform much better than a single covered lens. Being “better” depends on the maker’s lens treatment innovation and the quality of components used in creating the rifle scope.
Rifle Scope Lens Hydrophobic Finish
Water on an optic’s lens does not support preserving a clear sight picture through an optic at all. Numerous top of the line or high-end optic producers 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 surface of the Steiner glass lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Options for Mounting Rifle Optics on Firearms
Installing approaches for scopes can be found in a couple of choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually can be found in quick release versions which use toss levers which enable rifle operators to quickly mount and dismount the scopes.
Hex Key Rifle Scope Ring Mounts
Basic, clamp design mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use double independent rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are created for far away precision shooting. This kind of scope mount is good for rifles which need a durable, rock solid mount which will not shift despite how much the scope is moved or jarring the rifle takes. These are the style of mounts you should get for a dedicated optics setup on a reach out and touch someone hunting or sniper competition firearm which will seldom need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount screws to stop the hex screws from wiggling out after they are mounted tightly in position. An example of these mounting rings are the 30mm type made by the Vortex Optics brand. The set generally costs around $200 USD
Quick-Release Cantilever Glass 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. Numerous scopes can also be swapped out if they all use a similar design mount. These types of mounts come in handy for rifle platforms which are carried a lot, to remove the optic from the rifle for protection, or for optics which are used in between numerous rifles or are situationally focused.
About Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your expensive optic by causing fogging and developing residue inside of the scope tube. The majority of scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Optic Gas Purging
Another element of preventing 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 scope is less altered by climate shifts and pressure variations from the outdoor environment which could possibly allow water vapor to seep 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.
