Optic Facts
Rifle scopes allow you to exactly aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by employing a set of lenses within the scope. The scope’s positioning can be adjusted to take into account different ecological factors like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based upon the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. Many modern rifle scopes and optics have around 11 parts which are found inside and outside of the scope body. These parts include the rifle scope’s body, lenses, windage and elevation dials or turrets, objective focus rings, and other parts. See all eleven parts of scopes.
About Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The type of focal plane an optic has identifies where the reticle or crosshair lies in connection with the scopes zoom. It actually implies the reticle is situated behind or ahead of the magnification lens of the scope. Selecting the most effective kind of rifle glass depends on what sort of shooting or hunting you plan on doing.
First Focal Plane Optics
First focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This causes the reticle to increase in size based upon the amount of zoom being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non magnified distance. As an example, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” correlations for their weapon
- Shooters who do not mind the reticle is bigger and requires more visual eyesight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Long distance forms of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots occur within shorter proximities and ranges
- Shooters who select a clearer optic picture without room used up by the larger size FFP reticle
Magnification for Glass
The amount of scope zoom you require is based on the type of shooting you like to do. Just about every type of rifle glass provides some level of magnification. The quantity of zoom a scope supplies is identified by the diameter, thickness, and curves of the lens glass within the rifle optic. The zoom of the scope is the “power” of the glass. This denotes what the shooter is aiming at through the scope is amplified times the power factor of what can typically be seen by human eyes.
Info About Single Power Lens Scopes
A single power rifle optic or scope uses 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 type of scope can not fluctuate since it is a fixed power scope.
About Adjustable Power Lens Scopes
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom amount in a configuration like 2-10×32. These numbers indicate the magnification of the scope can be set in between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power modification is accomplished utilizing the power ring component of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range Correlation of Glass
Here are some advised scope power settings and the distances where they can be successfully used. Consider that higher power optics will not be as practical as lower powered glass because excessive zoom can be a detractor. The very same idea applies to extended distances where the shooter needs to have increased power to see where to properly aim the rifle.
Lens Coating for Scopes
All modern-day rifle scope and optic lenses are covered in special coatings. There are different types and qualities of finishings. When considering luxury rifle optical devices, Lens finishing can be a critical component of defining the capability of the rifle. The glass lenses are one of the most critical parts of the glass considering they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses offers protection to the lens surface and also improves anti glare from refracted sunshine and color presence.
HD Versus ED Lens Coatings
Some glass manufacturers even use “HD” or high-def lense coverings that apply different procedures, elements, polarizations, and chemicals to enhance a wide range of color ranges and viewable target definition through the lens. This HD finish is commonly used with greater density lens glass which brings down light’s capability to refract by means of the lens glass. Some scope vendors 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 also called color distortion or fringing. Chromatic aberration is often visible around objects with hard edges and shapes as light hits the item from specific angles.
Info on Single Finish 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 finish used to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing glare and other less helpful 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 you paid for it.
Some scope producers also make it a point to define if their optic lenses are coated or “multi” coated. Being “much better” depends on the maker’s lens treatment innovation and the quality of products used in developing the rifle scope.
Hydrophobic Glass Lens Covering
Water on a scope’s lens doesn’t assist with keeping a clear sight picture through an optic in any way. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the surface area of the Steiner glass lens so the water molecules can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Alternatives for Installing Optics on Firearms
Mounting approaches for scopes come in a few choices. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also usually are made in quick release versions which use manual levers which enable rifle shooters to quickly mount and remove the scope.
Hex Key Scope Ring Mounting Solutions
Standard, clamp type mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use two detached rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are made for far away accuracy shooting. This form of scope mount is great for rifle systems which need to have a durable, unfailing mount which will not move despite just how much the scope is moved or abuse the rifle takes. These are the design of mounts you want for a specialized optics system on a far away hunting or competition firearm that will seldom need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount screws to stop the hex screws from backing out after they are mounted safely in position. An example of these rings are the 30mm style from Vortex Optics. The set generally costs around $200 USD
Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope and attach it to a different rifle. Numerous scopes can also be switched out if they all use a compatible design mount. These types of mounts come in handy for rifles which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between several rifles.
Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by causing fogging and creating residue inside of the scope tube. Many scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Rifle Optic Gas Purging
Another component of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the glass is less influenced by temperature level shifts and pressure differences from the outside environment which could potentially allow water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
