Glass Details
Rifle scopes permit you to precisely align a rifle at different targets by lining up your eye with the target over a distance. They do this through zoom by utilizing a set of lenses inside the scope. The scope’s positioning can be adjusted for consideration of different ecological elements like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based upon the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes have around 11 parts which are found inside and outside of the optic. These scope parts consist of the rifle scope’s body, lenses, elevation dials or turrets, objective focus rings, and other parts. Learn about the eleven parts of optics.
About Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the optimal type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Glass
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the level 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. As an example, one tick on a mil-dot reticle at 100 yards without any “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are minimal
- Experienced shooters who understand their target “hold over” as well as “lead” correlations for their firearm
- Shooters who do not mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle behind the magnification lens. This induces the reticle to stay at the exact same overall size relative to the level of zoom being used. The effect is that the reticle dimensions alter based on the zoom applied to shoot over greater distances because the markings present different increments which fluctuate with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These types of scopes work for:
- Far away styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots take place within shorter ranges and distances
- Shooters who like a clearer optic sight picture without room used up by the bigger FFP reticle
Magnification for Rifle Scopes
The quantity of scope zoom you need on your optic depends on the kind of shooting you like to do. Practically every kind of rifle optic provides some level of zoom. The amount of zoom a scope delivers is established by the diameter, density, and curvatures of the lenses within the rifle scope. The zoom of the scope is the “power” of the scope. This suggests 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 About Fixed Power Lens Rifle Scopes
A single power rifle scope uses a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate considering that it is fixed.
About Variable Power Lens Glass
Variable power rifle scopes can be changed between magnification power levels. These types of scopes will note the zoom level in a configuration like 2-10×32. These numbers mean the magnification of the scope could be changed between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power adjustment is achieved by applying the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some recommended scope power levels and the distances where they can be efficiently used. High power scopes will not be as effective as lower powered glass given that too much zoom can be a negative aspect depending on your shooting distance. The same concept relates to longer ranges where the shooter needs adequate power to see where to best aim the rifle.
Rifle Scope Lens Finish
All top of the line rifle scope and optic lenses are layered. Lens covering is an essential element of a rifle system when buying high end rifle optics and scope equipment.
HD Versus ED Lenses
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use various procedures, polarizations, components, and chemicals to draw out various colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
About Single Covering Versus Multi-Coating
Various optic lenses can likewise have different coverings applied to them. All lenses normally have at least some type of treatment or finish applied to them before being used in a rifle scope or optic.
This lens treatment can protect 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 covered lens depends on the scope manufacturer and how much you paid for it.
Some scope manufacturers likewise make it a point to define if their optic lenses are coated or “multi” coated. This indicates the lens has had numerous treatments applied to them. If a lens receives multiple treatments, it can indicate that a maker is taking multiple steps to fight different natural aspects like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This additionally does not necessarily indicate the multi-coated lens will perform better than a single coated lens. Being “better” hinges on the maker’s lens treatment innovation and the quality of glass used in constructing the rifle scope.
Anti-water Lens Coating
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Many top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic anti-water finish.
Options for Installing Rifle Optics on Firearms
Installing approaches for scopes are available in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also typically can be found in quick release versions which use throw levers which enable rifle operators to rapidly mount and dismount the glass.
Rifle Scope Mounts with Hex Key Rings
Basic, clamp-on style mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on the tops of rifles. These forms of scope mounts use double independent rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are developed for long distance accuracy shooting. This kind of scope mount is good for rifles which are in need of a durable, hard use mount which will not change despite just how much the scope is moved or jarring the rifle takes. These are the type of mounts you really want to have for a dedicated scope system on a reach out and touch someone hunting or sniper competition rifle that will pretty much never need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to keep the hex screw threads from backing out after they are mounted tightly in position. An example of these rings are the 30mm style from the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, several scopes can also be switched on the range. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping the original sighting settings. These kinds of mounts are useful and convenient for shooting platforms which are shipped a lot, to take off the glass from the rifle for protection, or for sight systems which are utilized in between multiple rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It normally costs around $250 USD
Details on Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day on the range and your costly optic by causing fogging and generating residue inside of the scope tube. Many optics protect against moisture from going into the scope tube with a series of sealing O-rings which are waterproof. Usually, these scopes can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture content avoidance for common use rifles, unless you anticipate taking your rifle aboard a watercraft and are worried about the optic still working if it falls overboard and you can still find the rifle.
Details on Rifle Glass Tube Gas Purging
Another component of preventing the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the scope is less impacted by temperature level changes and pressure variations from the outside environment which might potentially allow water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
