What You Need to Know About Rifle Optics
Rifle scopes permit you to exactly aim a rifle at various targets by aligning your eye with the target over a range. They do this through zoom by using a set of lenses inside the scope. The scope’s positioning can be adapted for consideration of various natural elements like wind speed and elevation to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based upon the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes and optics have about 11 parts which are located internally and on the exterior of the scope. These scope parts include the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other parts. See all eleven parts of a rifle scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the finest type of rifle glass is based on what type of shooting you plan on doing.
First Focal Plane Optic Facts
First focal plane scopes (FFP) feature the reticle ahead of the magnification lens. This causes the reticle to increase in size based on the level of zoom being used. The benefit is that the reticle measurements are the same at the enhanced distance as they are at the non amplified range. For example, one tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who recognize their target “hold over” as well as “lead” correlations for their firearm
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight area than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane glass (SFP) include the reticle to the rear of the magnification lens. This causes the reticle to stay at the very same overall size in relation to the volume of magnification being used. The end result is that the reticle measurements change based on the zoom employed to shoot over greater ranges considering that the reticle measurements present various increments which differ with the zoom. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These styles of glass are beneficial for:
- Far away types of shooting where shooters have more time to make ballistic computations
- Shooting where most shots happen within much shorter ranges and proximities
- Shooters who select a clearer optic sight picture without space taken up by the bigger FFP reticle
Optic Zoom
The extent of scope magnification you need on your optic depends upon the kind of shooting you plan to do. Virtually every type of rifle glass supplies some amount of zoom. The quantity of zoom a scope gives is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle optic. The magnification of the scope is the “power” of the opic. This means what the shooter is checking out through the scope is amplified times the power aspect of what can typically be seen by human eyes.
Info on Single Power Lens Optics
A single power rifle optic will have a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not adjust given that it is a fixed power scope.
Info About Adjustable Power Lens Glass
Variable power rifle scopes can be modified between magnified 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 Levels and Range Correlations
Here are some recommended scope power settings and the ranges where they can be efficiently used. Keep in mind that high magnification glass will not be as practical as lower magnification level glass since excessive magnification can be a bad thing. The same concept applies to extended ranges where the shooter needs increased power to see precisely where to properly aim the rifle at the target.
Details on Scope Lens Finish
All modern rifle optic lenses are layered. There are various types and qualities of lens coatings. When looking at high end rifle targeting devices, Lens coating can be a very important element of defining the rifle’s capability. The lenses are among the most important parts of the optic given that they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses protects the lens surface area and even helps with anti glare from refracted direct sunlight and color perception.
HD Versus ED Glass Lens Coatings
Some rifle scope companies will also use “HD” or high-def lens coverings which take advantage of different procedures, chemicals, components, and polarizations to enhance numerous color ranges and viewable target visibility through lenses. This HD covering is normally used with increased density lens glass which decreases light’s opportunity to refract through the lens glass. Some scope suppliers use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration may be noticeable over items with hard shapes as light hits the item from particular angles.
Single Finish Versus Multi-Coating
Different scope lenses can even have different finishings applied to them. All lenses usually have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It needs to have a finish applied to it so that the lens will be optimally usable in lots of kinds of environments, degrees of light (full VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less useful 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 money you spent on it. Both the manufacturer and amount are signs of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are coated or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of products used in developing the rifle scope.
Hydrophobic Glass Lens Covering
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Many top of the line and military grade optic companies will coat their lenses with a hydrophobic or hydrophilic anti-water finish.
Scope Installation Alternatives
Installing options for scopes come in a couple of options. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also typically are made in quick release versions which use toss levers which permit rifle operators to rapidly install and remove the glass.
Rifle Optic Mounting Solutions with Hex Key Rings
Standard, clamp-on design mounting optic rings use hex head screws to position to the flattop design Picatinny scope mount rails on rifles. These forms of scope mounts use a pair of detached rings to support the optic, and are made from 7075 T6 billet aluminum which are created for far away accuracy shooting. This kind of scope mount is effective for rifles which need to have a long lasting, rock solid mount which will not shift despite just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you really want to have for a faithful scope setup on a far away hunting or interdiction rifle that will almost never need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount’s screws to prevent the hex screw threads from backing out after they are installed safely in place. An example of these mounting rings are the 30mm style from Vortex Optics. The set normally costs around $200 USD
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
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 swapped out if they all use a compatible style mount. These types of mounts are handy for rifles which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between multiple rifles or are situationally focused.
Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your expensive optic by triggering fogging and developing residue inside of the scope tube. Many scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Info on Scope Tube Gas Purging
Another part of preventing the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the scope is less affected by condition alterations and pressure differences from the external environment which may potentially allow water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
