What You Need to Know About Rifle Optics
Rifle scopes permit you to specifically align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by using a set of lenses within the scope. The scope’s alignment can be adjusted to account for different ecological aspects like wind and elevation increases to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based on the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended target. Most contemporary rifle scopes have about 11 parts which are found inside and on the exterior of the scope. These parts include the rifle scope’s body, lenses, adjustment dials, focus rings, and other elements. See all eleven parts of an optic.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the finest type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This induces the reticle to increase in size based on the amount of magnification being used. The outcome is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. For instance, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are minor
- Experienced shooters who recognize their aim point “hold over” as well as “lead” correlations for their weapon
- Shooters who do not mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane optics (SFP) feature the reticle behind the magnifying lens. This induces the reticle to stay at the exact same dimensions relative to the amount of zoom being used. The final result is that the reticle dimensions shift based upon the zoom applied to shoot over lengthier distances considering that the reticle markings represent distinct increments which vary with the magnification level. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick. These varieties of scopes are handy for:
- Far away types of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who like a clearer optic picture without area used up by the larger size FFP reticle
Rifle Optic Zoom
The measure of scope magnification you need on your optic depends upon the form of shooting you desire to do. Pretty much every type of rifle scope provides some degree of magnification. The quantity of zoom a scope supplies is identified by the size, density, and curves of the lenses within the rifle optic. The zoom of the scope is the “power” of the glass. This means what the shooter is checking out through the scope is amplified times the power element of what can generally be seen by human eyes.
Single Power Lens Scope Info
A single power rifle optic and scope comes with 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 change since it is fixed.
Variable Power Lens Rifle Scope Facts
Variable power rifle scopes can be changed between magnification levels. These types of scopes will note the zoom degree in a format like 2-10×32. These numbers indicate the magnification of the scope can be changed in between 2x and 10x power. This also includes the powers in-between 2 and 10. The power adjustment is accomplished by employing the power ring part of the scope near the back of the scope by the eye bell.
Optic Power Level and Range Correlation
Here are some recommended scope power settings and the distances where they can be efficiently used. Bear in mind that high magnification scopes will not be as efficient as lower powered optics and scopes because excessive zoom can be a detractor. The same goes for longer ranges where the shooter needs to have increased power to see precisely where to best aim the rifle at the target.
Lens Coating for Rifle Glass
All current rifle scope and optic lenses are layered. Lens coating can be an important element of a shooting platform when buying high end rifle optics and scope setups.
About Scope Lens Coatings – HD Versus ED
Some glass companies will also use “HD” or high-def glass finishes that make the most of various procedures, elements, polarizations, and chemical applications to extract separate color ranges and viewable definition through the lens. This high-def covering is commonly used with more costly high density glass which brings down light’s opportunity to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be visible around objects with well defined shapes as light hits the object from certain angles.
Single Finish Versus Multi-Coating
Various scope lenses can even have different finishings applied to them. All lenses generally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in lots of types of environments, degrees of light (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” coated. This indicates the lens has had multiple treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can prove that a company is taking multiple actions to combat different environmental elements like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This also does not necessarily suggest the multi-coated lens will perform much better than a single coated lens. Being “better” hinges on the maker’s lens treatment innovation and the quality of materials used in developing the rifle optic.
Rifle Optic Lens Anti-water Finishing
Water on a scope’s lens does not assist with preserving a clear sight picture through an optic in any way. Many top of the line and high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the exterior of the Steiner scope lens so the water particles can not bind to it or produce surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Optic Installation Alternatives
Mounting solutions for scopes are available in a few options. There are the basic scope rings which are individually installed 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 quickly mount and remove the scope.
Hex Key Scope Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long range precision shooting. This type of scope install is excellent for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be switched out if they all use a compatible style mount. These types of mounts are handy for rifle platforms which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are used between several rifles or are situationally focused.
Sealing and Gas Purging for Glass Tubes
Wetness inside your rifle optic can wreck a day on the range and your highly-priced optic by causing fogging and developing residue within the scope tube. The majority of scopes protect against humidity from getting in the optical tube with a system of sealing O-rings which are water resistant. Usually, these optics can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture content prevention for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard watercrafts and are worried about the scope still functioning if it goes over the side and you can still find the rifle.
Gas Purged Optic 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. Because this area is already taken up by the gas, the glass is less affected by climate changes and pressure differences from the outside environment which could possibly allow 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.
