Rifle Scope Facts
Rifle scopes permit you to precisely align a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnifying the target by using a series of lenses within the scope. The scope’s positioning can be adapted to take into account varied ecological aspects like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the intended target. Many modern rifle scopes have around 11 parts which are found internally and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other elements. See all eleven parts of a rifle scope.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the optimal type of rifle optic depends on what type of shooting you plan to do.
First Focal Plane Optic Info
First focal plane optics (FFP) come with the reticle in front of the magnifying lens. This causes 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 magnified range as they are at the non magnified range. As an example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at 100 yards using 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where estimations are very little
- Experienced shooters who have an idea for their aim point “hold over” and “lead” relationships for their long gun
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight room than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick.
- Far away styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots take place within much shorter ranges and proximities
- Shooters who would like a clearer optic sight picture with less area used up by the bigger FFP reticle
Magnification for Glass
The amount of magnification a scope provides is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Glass Facts
A single power rifle optic will have a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not fluctuate considering that it is a set power scope.
Variable Power Lens Optics
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification level in a format such as 2-10×32. These numbers mean the magnification of the scope could be changed in between 2x and 10x power. This also incorporates the power levels in-between 2 and 10. The power shift is achieved by working with 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 could be successfully used. Bear in mind that higher power optics will not be as effective as lower powered scope and optics due to the fact that increased magnification can be a negative thing in certain situations. The same goes for extended ranges where the shooter needs adequate power to see precisely where to best aim the rifle at the target.
Details on Rifle Glass Lens Finishing
All modern-day rifle optic lenses are covered in special coatings. There are various types and qualities of coverings. Lens covering can be an essential aspect of a rifle’s setup when looking into high-end rifle optics and scope units. The lenses are among the most crucial 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 offers protection to the lens surface and improves anti glare from refracted sunrays and color recognition.
HD Versus ED Lens Coatings
Some scope manufacturers additionally use “HD” or high-def glass coatings that employ various procedures, rare earth compounds, aspects, and polarizations to enhance a wide range of color ranges and viewable definition through the lens. This HD coating is often used with greater density glass which decreases light’s chance to refract through the lens glass. Some scope makers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration may be obvious over items with hard shapes as light hits the item from particular angles.
Rifle Glass Lens Single Covering Versus Multi-Coating
Different optic lenses can also have different coatings applied to them. All lenses typically have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends on the scope manufacturer and how much you spent on it. Both the manufacturer and amount are indications of the lens quality.
Some scope manufacturers likewise make it a point to specify if their optic lenses are coated or “multi” coated. This indicates the lens has had several treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can establish that a maker is taking multiple actions to combat various natural aspects like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This additionally does not necessarily mean the multi-coated lens is much better than a single covered lens. Being “better” depends upon the producer’s lens treatment innovation and the quality of components used in creating the rifle optic.
Hydrophobic Lens Coatings
Water on an optical lens doesn’t support retaining a clear sight picture through a scope at all. Many top of the line or premium scope makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the surface of the Steiner scope lens so the H2O molecules can not bind to it or create surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Options for Installing Rifle Optics on Long Guns
Installing solutions for scopes can be found in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually can be found in quick release variations which use toss levers which allow rifle shooters to rapidly install and dismount the glass.
Hex Key Rifle Glass Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long range precision shooting. This type of scope install is wonderful for rifles which require a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. Several scopes can also be switched out if they all use a similar designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining accuracy. These types of mounts are useful and practical for rifles which are moved a lot, to remove the scope from the rifle for protection, or for scopes which are used between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It generally costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle optic can mess up a day of shooting and your highly-priced optic by resulting in fogging and producing residue within the scope tube. Many optics protect against wetness from going into the optical tube with a series of sealing O-rings which are waterproof. Typically, these water resistant scopes can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity prevention for conventional use rifles for hunting and sporting purposes, unless you intend on taking your rifle on your motorboat and are concerned about the optic still functioning if it falls overboard and you can still find the gun.
Gas Purged Rifle Scope Tubes
Another part of avoiding the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the glass is less affected by temp alterations and pressure distinctions from the outside environment which might possibly enable 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.
