Information About Rifle Optics
Rifle scopes enable you to specifically aim a rifle at various targets by lining up your eye with the target over a distance. They do this through magnification by using a series of lenses within the scope. The scope’s alignment can be adapted to account for varied environmental factors like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the target. A lot of contemporary rifle scopes have around eleven parts which are arranged within and externally on the scope body. These scope parts include the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other parts. Learn about the eleven parts of scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the finest type of rifle scope depends on what type of shooting you plan to do.
First Focal Plane Optic Details
First focal plane glass (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the amount of zoom being used. The outcome 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 with no “zoom” is still the same tick at 100 yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are small
- Experienced shooters who understand their target “hold over” and also “lead” equations for their rifles
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. 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.
- Far away forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who would like a clearer optic sight picture without room taken up by the bigger FFP reticle
Magnification for Scopes
The extent of scope magnification you need on your glass depends upon the form of shooting you intend to do. Nearly every type of rifle optic offers some amount of zoom. The quantity of zoom a scope offers is identified by the dimension, density, and curvatures of the lens glass within the rifle scope. The magnification of the optic is the “power” of the opic. This signifies what the shooter is aiming at through the scope is magnified times the power factor of what can generally be seen by human eyes.
Info About Single Power Lens Rifle Optics
A single power rifle scope will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not adjust because it is a fixed power optic.
About Adjustable Power Lens Scopes
Variable power rifle scopes have adjustable power. It will list the magnification level in a configuration like 2-10×32. These numbers mean the zoom of the scope can be changed in between 2x and 10x power. This always includes the power levels in-between 2 and 10. The power modification is accomplished by working with the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range of Glass
Here are some suggested scope power settings and the ranges where they can be efficiently used. Bear in mind that high magnification optics and scopes will not be as efficient as lower magnification level scope and optics due to the fact that increased magnification can be a detractor. The very same idea goes for extended distances where the shooter needs to have enough power to see where to best aim the rifle.
Info on Scope Lens Coatings
All contemporary rifle optic lenses are coated. There are various types and qualities of coverings. When shopping for high end rifle optics and scope setups, Lens covering can be a significant element of defining the capability of the rifle. The glass lenses are among the most vital parts of the optic considering they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses protects the lens exterior and even improves anti glare capabilities from excess light and color visibility.
ED Versus HD Scopes
Some optic companies even use “HD” or high-def lens coverings which employ various procedures, aspects, polarizations, and chemical applications to draw out separate color ranges and viewable target definition through lenses. This HD coating is frequently used with increased density glass which lowers light’s potential to refract through the lens glass. Some scope makers use “HD” to describe “ED” meaning extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around items with well defined shapes as light hits the object from particular angles.
What to Know About Single Coating Versus Multi-Coating
Different optic lenses can likewise have various coverings used to them. All lenses usually have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while lowering glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you paid for it.
Some scope makers likewise make it a point to define if their optic lenses are coated or “multi” coated. This means the lens has had numerous treatments applied to the surfaces. If a lens gets several treatments, it can show that a maker is taking several actions to fight various environmental factors like an anti-glare covering, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This additionally does not always mean the multi-coated lens will perform much better than a single coated lens. Being “much better” hinges on the maker’s lens treatment techniques and the quality of materials used in building the rifle glass.
Anti-water Covering for Rifle Glass
Water on a scope’s lens does not assist with keeping a clear sight picture through a scope at all. Many top of the line and premium optic producers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the exterior surfaces of the Steiner optic lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Rifle Optic Installing Alternatives
Installing solutions for scopes can be found in a couple of options. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These various types of mounts also normally are made in quick release variations which use manual levers which allow rifle operators to quickly mount and dismount the glass.
Hex Key Optic Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two different rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope install is fine for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible style mount. These types of mounts are convenient for rifles which are transferred a lot, to swap out the optic from the rifle for protection, or for optics which are used in between multiple rifles or are situationally focused.
Details on Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. A lot of scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Optic Tubes
Another part of avoiding the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the optic is less influenced by condition changes and pressure variations from the external environment which might potentially permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
