Glass Facts
Rifle scopes allow you to specifically align a rifle at various targets by aligning your eye with the target over a distance. They do this through magnification using a series of lenses inside the scope. The scope’s alignment can be dialed in for consideration of different natural factors like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the target. A lot of modern rifle optics have around eleven parts which are arranged within and on the exterior of the optic. These parts consist of the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other components. Learn about the eleven parts of rifle scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the finest type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who understand their aim point “hold over” as well as “lead” equations for their firearms
- Shooters who don’t mind the reticle is bigger and requires more visual sight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle behind the magnifying lens. This induces the reticle to stay at the same overall size in relation to the volume of zoom being used. The outcome is that the reticle dimensions change based upon the magnification chosen to shoot over lengthier ranges since the reticle markings represent distinct increments which change with the magnification. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular varieties of scopes are handy for:
- Long distance styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots occur within much shorter ranges and proximities
- Shooters who desire a clearer optic sight picture without room used up by the enlarged FFP reticle
Rifle Scope Magnification
The level of scope zoom you require is based on the kind of shooting you would like to do. Practically every style of rifle scope gives some level of magnification. The quantity of magnification a scope provides is established by the dimension, density, and curvatures of the lenses inside of the rifle scope. The magnifying level of the optic is the “power” of the glass. This signifies what the shooter is aiming at through the scope is amplified times the power aspect of what can normally be seen by human eyes.
Fixed Power Lens Rifle Scope Facts
A single power rifle scope uses a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust because it is a fixed power optic.
Adjustable Power Lens Rifle Scope Info
Variable power rifle scopes can be adjusted between magnification levels. It will note the magnification amount in a configuration such as 2-10×32. These numbers mean the zoom of the scope can be set between 2x and 10x power. This additionally utilizes the powers in-between 2 and 10. The power adjustment is accomplished by applying the power ring component of the scope near the back of the scope by the eye bell.
Rifle Glass Power and Ranges
Here are some recommended scope power levels and the distances where they can be successfully used. High power rifle scope glass will not be as efficient as lower magnification level scopes considering that too much zoom can be a bad thing. The same concept goes for extended distances where the shooter needs increased power to see where to properly aim the rifle at the target.
Info on Rifle Optic Lens Coating
All present day rifle optic and scope lenses are coated. Lens covering is a crucial element of a rifle when purchasing high end rifle optics and scope equipment.
Details on Lens Coatings – HD Versus ED
Some scope manufacturers likewise use “HD” or high-definition lens coatings which use various techniques, polarizations, chemicals, and aspects to draw out various colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
What to Know About Single Finishing Versus Multi-Coating
Different optic lenses can also have different coatings applied to them. All lenses usually have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less beneficial 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 producers similarly make it a point to specify if their optic lenses are coated or “multi” coated. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Hydrophobic Rifle Scope Lens Covering
Water on a scope’s lens does not help with preserving a clear sight picture through an optic at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the surface of the Steiner scope lens so the water molecules can not bind to it or create surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Options for Mounting Optics on Long Guns
Mounting approaches for scopes come in a couple of options. 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 typically come in quick release versions which use manual levers which permit rifle shooters to quickly mount and dismount the scopes.
Hex Key Scope Ring Mounts
Basic, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on the tops of rifles. These styles of scope mounts use double independent rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope mount is good for rifles which need to have a resilient, unfailing mount which will not change despite just how much the scope is moved about or jarring the rifle takes. These are the design of mounts you really want to have for a specialized optics setup on a long distance scouting or competitors firearm that will pretty much never need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used to prevent the hex screws from backing out after they are installed firmly in position. An example of these rings are the 30mm style made by the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounts
These kinds of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, several scopes can often be swapped on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping precision. These types of mounts come in convenient for shooting platforms which are transported a lot, to take off the scope from the rifle for protection, or for optics which are used in between several rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It typically costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. Most scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
About Scope Tube Gas Purging
Another part of preventing the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the optic is less influenced by condition shifts and pressure differences from the outside environment which may possibly permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
