Scope Information
Rifle scopes permit you to specifically aim a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through zoom by utilizing a series of lenses inside the scope. The scope’s positioning can be adapted to account for various ecological elements like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s function is to understand precisely where the bullet will land based upon the sight picture you are seeing via the scope as you align the scope’s crosshair or reticle with the intended target. Most contemporary rifle scopes and optics have around eleven parts which are arranged internally and outside of the scope. These parts include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other elements. See all eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the optimal type of rifle glass is based around what type of shooting you plan to do.
Info on First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This induces the reticle to increase in size based upon the level of magnification being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non amplified distance. For instance, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at one hundred yards using 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are minimal
- Experienced shooters who have an idea for their target “hold over” and “lead” relationships for their long guns
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight space than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle behind the magnifying lens. This triggers the reticle to remain at the same scale relative to the volume of zoom being used. The end result is that the reticle dimensions adjust based upon the magnification employed to shoot over longer distances due to the fact that the reticle markings represent distinct increments which can vary with the magnification level. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick. These particular styles of optics work for:
- Long distance kinds of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots occur within shorter spaces and ranges
- Shooters who want a clearer optic sight picture with less room taken up by the larger size FFP reticle
Details on Rifle Scope Magnification
The amount of magnification a scope offers is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Scope Facts
A single power rifle scope and optic comes with a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not fluctuate since it is fixed.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be modified between magnified levels. The power adjustment is handled by the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some suggested scope power levels and the distances where they could be successfully used. Highly magnified rifle scope glass will not be as useful as lower magnification level glass given that too much zoom can be a negative aspect depending on your shooting distance. The exact same idea relates to extended distances where the shooter needs enough power to see exactly where to best aim the rifle.
Info on Lens Finishes
All contemporary rifle scope lenses are coated. There are different types and qualities of lens coverings. When shopping for luxury rifle targeting systems, Lens finish can be a significant component of a rifle. The lenses are among the most significant parts of the scope considering they are what your eye sees through while sighting a rifle in on the point of impact. The coating on the lenses offers protection to the lens surface as well as helps with anti glare capabilities from excess direct sunlight and color visibility.
HD Versus ED Lenses
Some scope makers also use “HD” or high-definition lens coatings which use different methods, aspects, polarizations, and chemicals to draw out various colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Different optic lenses can also have various finishes used to them. All lenses normally have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can safeguard 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 upon the scope manufacturer and just how much you spent for it. Both the make and cost are indicators of the lens quality.
Some scope producers also make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Optic Lens Hydrophobic Covering
Water on a scope’s lens does not improve keeping a clear sight picture through a scope whatsoever. Lots of top of the line and premium optic producers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the surface area of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The outcome is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Scope Mounting Alternatives
Mounting options for scopes can be found in a couple of choices. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also generally come in quick release variations which use toss levers which enable rifle operators to quickly install and dismount the scope.
Glass Mounts with Hex Key Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope install is perfect for rifles which require a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Optic Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle. If they all use a comparable design mount, a number of scopes can also be swapped out. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining the original sighting settings. These kinds of mounts come in handy for shooting platforms which are transferred between vehicles a lot, to take off the scope from the rifle for protection, or for sight systems which are chosen for use in between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can spoil a day of shooting and your expensive optic by resulting in fogging and producing residue within the scope tube. The majority of optics protect against wetness from getting in the scope tube with a series of sealing O-rings which are waterproof. Normally, these water resistant scopes can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture avoidance for conventional use rifles for hunting and sporting purposes, unless you anticipate taking your rifle aboard watercrafts and are concerned about the optic still functioning if it goes overboard and you can still recover the rifle.
Rifle Glass Gas Purging
Another part of avoiding the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the optic is less affected by temp alterations and pressure differences from the external environment which may possibly enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
