Scope Details
Rifle scopes allow you to specifically aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnifying the target by using a series of lenses within the scope. The scope’s alignment can be adapted for the consideration of numerous environmental aspects like wind speed and elevation to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes and optics have around eleven parts which are located inside and on the exterior of the scope body. These scope parts consist of the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other components. Learn about the eleven parts of optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the optimal type of rifle glass is based around what type of shooting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who have an idea for their target “hold over” as well as “lead” relationships for their rifles
- Shooters who don’t mind the reticle is bigger and requires more visual sight area than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle to the rear of the magnifying lens. This triggers the reticle to remain at the same overall size in connection with the level of zoom being used. The outcome is that the reticle dimensions evolve based upon the magnification applied to shoot over greater distances considering the markings present distinct increments which can vary with the zoom. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular styles of optics work for:
- Far away forms of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots happen within shorter ranges and proximities
- Shooters who like a clearer optic picture without area taken up by the larger sized FFP reticle
Zoom for Rifle Glass
The amount of scope magnification you need on your scope is based on the type of shooting you wish to do. Just about every style of rifle optic delivers some level of magnification. The amount of zoom a scope offers is identified by the dimension, thickness, and curves of the lenses within the rifle optic. The magnification level of the optic is the “power” of the scope. This denotes what the shooter is observing through the scope is magnified times the power factor of what can normally be seen by human eyes.
Info on Fixed Power Lens Scopes
A single power rifle optic will have 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 zoom of this kind of optic can not fluctuate since it is a fixed power scope.
About Variable Power Lens Rifle Scopes
Variable power rifle scopes use variable power levels. The power adjustment is handled using the power ring part of the scope near the back of the scope by the eye bell.
Rifle Glass Power and Range Correlation
Here are some recommended scope power levels and the ranges where they can be successfully used. Keep in mind that higher power optics will not be as efficient as lower powered optics due to the fact that increased zoom can be a negative thing in certain situations. The exact same concept goes for extended ranges where the shooter needs to have sufficient power to see exactly where to best aim the rifle at the target.
About Lens Finishing
All top of the line rifle scope and optic lenses are coated. Lens covering is a vital aspect of a rifle system when looking at high end rifle optics and scope equipment.
HD Versus ED Rifle Scope Lens Coatings
Some scope manufacturers also use “HD” or high-definition lens coatings which use various methods, components, chemicals, and polarizations to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Optic Lens Covering Versus Multi-Coating
Various optic lenses can likewise have various coverings used to them. All lenses typically have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope producer and how much you spent for it. Both are indicators of the lens quality.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in developing the rifle scope.
Glass Lens Hydrophobic Covering
Water on a scope’s lens does not support maintaining a clear sight picture through a scope in any way. Numerous top of the line and premium scope manufacturers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It deals with the surface of the Steiner scope lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Optic Mounting Choices
Installing approaches for scopes can be found in a few options. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also generally come in quick release variations which use manual levers which allow rifle shooters to rapidly install and dismount the scope.
Glass Mounts with Hex Key Rings
Standard, clamp style mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use double detached rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are developed for far away accuracy shooting. This form of scope mount is great for rifles which need to have a long lasting, hard use mount which will not shift despite how much the scope is moved or abuse the rifle takes. These are the design of mounts you want for a dedicated optics system on a long distance hunting or sniper competition rifle that will rarely need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to keep the hex screws from backing out after they are mounted tightly in position. An example of these rings are the 30mm style from Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can often be switched in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top design 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 maintaining the original sighting settings. These kinds of mounts are useful and beneficial for rifles which are moved around a lot, to take off the scope glass from the rifle for protection, or for optics which are adopted between several rifles. An example of this mount style is the 30mm mount from Vortex Optics. It usually costs around $250 USD
Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can spoil a day on the range and your pricey optic by triggering fogging and producing residue within the scope tube. The majority of scopes prevent humidity from getting in the optical tube with a system of sealing O-rings which are water resistant. Normally, these water resistant scopes can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample wetness prevention for conventional use rifles for hunting and sporting purposes, unless you intend on taking your rifle sailing and are concerned about the scope still working if it is submerged in water and you can still rescue the firearm.
Scope Gas Purging
Another part of preventing the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the glass is less impacted by temperature alterations and pressure variations from the outside environment which may possibly enable water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
