Optic Details
Rifle scopes enable you to specifically align a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through magnification by using a set of lenses within the scope. The scope’s positioning can be adapted to take into account varied natural aspects like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the target. The majority of modern rifle optics have about 11 parts which are found within and externally on the scope body. These parts include the rifle scope’s body, lenses, windage dials, focus rings, and other elements. See all eleven parts of scopes.
About Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the optimal type of rifle glass depends on what type of shooting you plan on doing.
First Focal Plane Optic Details
First focal plane glass (FFP) include the reticle ahead of the zoom lens. This induces the reticle to increase in size based upon the extent of zoom being used. The result is that the reticle measurements are the same at the magnified 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 same tick at 100 yards with 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who understand their target “hold over” and “lead” ratios for their long guns
- Shooters who do not mind the reticle is enlarged and takes up more visual eyesight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle behind the magnifying lens. This causes the reticle to remain at the exact same dimensions relative to the volume of magnification being used. The outcome is that the reticle measurements evolve based upon the zoom employed to shoot over longer ranges given that the reticle markings represent different increments which fluctuate with the magnification level. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular varieties of optics are useful for:
- Far away kinds of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots take place within shorter ranges and proximities
- Shooters who prefer a clearer optic picture without space used up by the bigger FFP reticle
About Rifle Scope Magnification
The quantity of scope zoom you need depends on the type of shooting you would like to do. Pretty much every style of rifle optic provides some level of zoom. The quantity of magnification a scope provides is established by the diameter, density, and curves of the lens glass inside of the rifle optic. The zoom of the scope is the “power” of the scope. This indicates what the shooter is looking at through the scope is magnified times the power factor of what can generally be seen by human eyes.
Info About Fixed Single Power Lens Glass
A single power rifle scope and optic will have a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not fluctuate given that it is a set power scope.
Adjustable Power Lens Glass Facts
Variable power rifle scopes use enhanced power. The power modification is performed by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Glass Power and Range Correlation
Here are some advised scope power levels and the ranges where they can be effectively used. Always remember that higher magnification optics will not be as practical as lower powered glass since too much magnification can be a detractor. The same applies to extended ranges where the shooter needs to have adequate power to see exactly where to properly aim the rifle at the target.
Lens Finish for Glass
All modern-day rifle optic lenses are covered in special coatings. There are different types and qualities of finishings. When researching high end rifle scope systems, Lens covering can be a vital aspect of defining the capability of the rifle. The lenses are among the most vital components 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 safeguards the lens surface and helps with anti glare from excess daylight and color recognition.
About Glass Lens Coatings – HD Versus ED
Some scope suppliers additionally use “HD” or high-def glass finishes which take advantage of various procedures, components, rare earth compounds, and polarizations to draw out separate color ranges and viewable target definition through lenses. This high-def covering is typically used with greater density glass which reduces light’s potential to refract through the lens glass. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around items with hard shapes as light hits the object from particular angles.
About Single Covering Versus Multi-Coating
Various optic lenses can likewise have various coatings used to them. All lenses generally have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while reducing glare and other less advantageous 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 manufacturers also make it a point to define if their optic lenses are coated or “multi” coated. Being “better” depends on the maker’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Anti-water Scope Lens Finishing
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic covering.
Choices for Mounting Rifle Glass on Firearms
Installing options for scopes are available in a couple of options. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also normally can be found in quick release versions which use toss levers which allow rifle shooters to quickly mount and remove the scope.
Hex Key Rifle Scope Ring Mounting Solutions
Basic, clamp style mounting optic rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use a pair of detached rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are developed for long distance precision shooting. This form of scope mount is ideal for rifles which need to have a long lasting, unfailing mount which will not move regardless of how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should get for a dedicated optics setup on a reach out and touch someone hunting or competition rifle that will almost never need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to prevent the hex screw threads from backing out after they are mounted firmly in place. An example of these mounting 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 rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Several scopes can also be switched out if they all use a similar style mount. These types of mounts come in handy for long guns which are transported a lot, to remove the optic from the rifle for protection, or for optics which are used in between numerous rifles or are situationally focused.
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can wreck a day on the range and your highly-priced optic by resulting in fogging and creating residue inside of the scope’s tube. The majority of optics protect against wetness from entering the scope tube with a system of sealing O-rings which are water resistant. Typically, these water resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture prevention for common use rifles, unless you anticipate taking your rifle aboard a watercraft and are worried about the optic still functioning if it is submerged in water and you can still retrieve the firearm.
Rifle Glass Gas Purging
Another component of avoiding the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the glass is less impacted by temp shifts and pressure variations from the outside environment which could possibly enable 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.
