Rifle Glass Facts
Rifle scopes allow you to exactly align a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom by utilizing a series of lenses within the scope. The scope’s alignment can be adjusted for the consideration of different ecological things like wind and elevation increases to account for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based on the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the target. Many modern-day rifle scopes have around 11 parts which are found within and outside of the scope body. These scope parts consist of the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other parts. See all eleven parts of scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the optimal type of rifle glass is based on what type of shooting you plan to do.
First Focal Plane Glass Info
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are low
- Experienced shooters who understand their target “hold over” as well as “lead” equations for their firearm
- Shooters who do not mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) come with the reticle behind the zoom lens. This causes the reticle to remain at the same size in connection with the level of magnification being used. The end result is that the reticle measurements evolve based on the magnification chosen to shoot over greater ranges because the reticle measurements represent various increments which differ with the zoom. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These types of scopes are useful for:
- Long distance forms of shooting where shooters have additional time to make ballistic computations
- Shooting where most of the shots take place within much shorter proximities and ranges
- Shooters who choose a clearer optic sight picture without space taken up by the enlarged FFP reticle
Rifle Scope Zoom
The quantity of zoom a scope supplies is identified 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.
Fixed Single Power Lens Rifle Glass Facts
A single power rifle optic and scope uses a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust since it is a fixed power optic.
Adjustable Power Lens Scope Details
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom level in a format like 2-10×32. These numbers suggest the zoom of the scope can be set between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power shift is achieved utilizing the power ring part of the scope near the rear of the scope by the eye bell piece.
Power Levels and Range Correlations
Here are some suggested scope power levels and the distances where they could be effectively used. Highly magnified rifle scope glass will not be as effective as lower magnification level rifle scope glass since too much magnification can be a negative aspect depending on your shooting distance. The exact same concept relates to extended distances where the shooter needs to have sufficient power to see exactly where to best aim the rifle.
About Lens Finish
All top teir rifle optic lenses are covered. Lens finish is a crucial element of a rifle system when purchasing high end rifle optics and scope equipment.
HD Versus ED Rifle Scope Lens Coatings
Some scope brands also use “HD” or high-definition lens finishes which use various techniques, polarizations, components, and chemicals to draw out different colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Info on Single Coating Versus Multi-Coating
Different optic lenses can likewise have various coatings applied to them. All lenses usually have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are coated or “multi” covered. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle scope.
Anti-water Lens Coatings
Water on an optic’s lens doesn’t improve retaining a clear sight picture through a scope at all. Numerous top of the line and high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the surface area of the Steiner glass lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads move off of the scope to maintain a clear, water free sight picture.
Rifle Optic Mounting Choices
Mounting options for scopes come in a couple of choices. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release versions which use toss levers which allow rifle shooters to rapidly install and dismount the scope.
Rifle Scope Mounts with Hex Key Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which is designed for long distance precision shooting. This type of scope mount is wonderful for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abused.
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle. If they all use a comparable design mount, multiple scopes can also be switched in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping precision. These kinds of mounts are useful and handy for rifles which are transported a lot, to take off the glass from the rifle for protection, or for optics which are employed between a number of rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Details on Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your expensive optic by bringing about fogging and creating residue inside of the scope tube. A lot of scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
What to Know About Rifle Scope Tube Gas Purging
Another component of preventing the buildup of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the scope is less impacted by condition shifts and pressure distinctions from the outdoor environment which may potentially 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 look for.
