Optic Information
Rifle scopes allow you to exactly align a rifle at different targets by aligning your eye with the target at range. They do this through magnification by employing a set of lenses inside the scope. The scope’s positioning can be adjusted to take into account different ecological aspects like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the target. A lot of contemporary rifle scopes have about 11 parts which are found within and externally on the optic. These parts consist of the rifle scope’s body, lenses, windage turrets, objective focus rings, and other parts. Learn about the eleven parts of rifle glass.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane a scope has determines where the reticle or crosshair is located in regard to the optic’s magnifying adjustments. It actually implies the reticle is behind or ahead of the magnification lens of the optic. Picking out the very best kind of rifle optic is dependent on what kind of shooting you plan on doing.
About First Focal Plane Optics
First focal plane scopes (FFP) come with the reticle ahead of the magnification lens. This induces the reticle to increase in size based upon the extent of zoom being used. The outcome is that the reticle measurements are the same at the enhanced distance as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the exact same tick at 100 yards by using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are very little
- Experienced shooters who know their target “hold over” plus “lead” ratios for their rifles
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Glass Info
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Far away types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots take place within much shorter proximities and ranges
- Shooters who prefer a clearer optic sight picture without room taken up by the larger size FFP reticle
Details on Scope Zoom
The level of scope magnification you require depends on the style of shooting you desire to do. Just about every type of rifle glass provides some degree of magnification. The volume of magnification a scope provides is established by the size, thickness, and curves of the lens glass inside of the rifle scope. The magnification of the optic is the “power” of the scope. This implies what the shooter is aiming at through the scope is magnified times the power element of what can usually be seen by human eyes.
Fixed Power Lens Rifle Glass
A single power rifle optic will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change since it is a set power scope.
Adjustable Power Lens Glass Facts
Variable power rifle scopes use variable power levels. The power change is achieved using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some suggested scope powers and the ranges where they may be effectively used. Keep in mind that higher magnification scopes will not be as efficient as lower powered scope and optics because too much zoom can be a bad thing. The same concept goes for extended ranges where the shooter needs increased power to see exactly where to properly aim the rifle at the target.
Info on Rifle Scope Lens Coatings
All modern rifle optic and scope lenses are layered. Lens coating can be an important element of a rifle’s setup when looking into high end rifle optics and scope setups.
HD Versus ED Rifle Scope Lens Coatings
Some rifle scope suppliers will also use “HD” or high-definition lense finishes that apply various processes, chemicals, polarizations, and elements to enhance various color ranges and viewable target definition through lenses. This high-def finish is commonly used with more costly high density lens glass which drops light’s potential to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration can be visible over things with well defined shapes as light hits the object from various angles.
Rifle Scope Lens Single Finishing Versus Multi-Coating
Different scope lenses can also have various finishings applied to them. All lenses usually have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be optimally usable in many kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
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 decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope manufacturer and how much money you spent on it. The scope’s maker and cost are signs of the lens quality.
Some scope manufacturers similarly make it a point to specify 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 constructing the rifle scope.
Details on Hydrophobic Finishing
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish.
Scope Mounting Choices
Mounting approaches for scopes are available in a couple of choices. There are the basic scope rings which are individually 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 enable rifle operators to rapidly mount and dismount the optics.
Rifle Glass Mounting Solutions with Hex Key Rings
Basic, clamp type mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These varieties of scope mounts use double independent rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are designed for far away accuracy shooting. This form of scope mount is ideal for rifles which require a long lasting, hard use mount which will not shift no matter how much the scope is moved or abuse the rifle takes. These are the type of mounts you should get for a dedicated scope system on a long distance scouting or interdiction firearm which will hardly ever need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on the screws to keep the hex screw threads from wiggling out after they are installed tightly in place. An example of these rings are the 30mm type made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly take off a scope and connect it to a different rifle. Numerous scopes can even be switched out if they all use a compatible style mount. These types of mounts are convenient for long guns which are carried a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles.
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle glass can mess up a day on the range and your expensive optic by triggering fogging and generating residue within the scope tube. The majority of optics prevent humidity from entering the scope tube with a series of sealing O-rings which are waterproof. Generally, these optics can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient humidity prevention for common use rifles, unless you plan on taking your rifle sailing and are worried about the scope still working if it goes over the side and you can still salvage the firearm.
Gas Purged Scope Tubes
Another element of preventing the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the optic is less altered by condition alterations and pressure distinctions from the external environment which could potentially permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
