About Glass
Rifle scopes enable you to exactly aim a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through zoom using a set of lenses within the scope. The scope’s alignment can be dialed in to take into account varied environmental factors like wind and elevation to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based on the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle optics have around 11 parts which are located within and externally on the scope body. These optic pieces consist of the rifle scope’s body, lenses, modification dials, focus rings, and other parts. Learn about the eleven parts of rifle optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the finest type of rifle optic is based on what type of shooting you plan on doing.
First Focal Plane Scope Info
First focal plane glass (FFP) feature the reticle in front of the zoom lens. This induces the reticle to increase in size based upon the extent of magnification being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at 100 yards with 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are low
- Experienced shooters who understand their target “hold over” and also “lead” correlations for their firearm
- Shooters who do not mind the reticle is bigger and requires more visual sight space than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the magnification 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 measurement.
- Long distance forms of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots happen within shorter ranges and distances
- Shooters who want a clearer optic sight picture with less room used up by the larger sized FFP reticle
Scope Magnification
The extent of scope zoom you need on your glass depends upon the sort of shooting you desire to do. Practically every kind of rifle optic provides some level of magnification. The amount of magnification a scope provides is established by the dimension, thickness, and curvatures of the lens glass inside of the rifle scope. The zoom of the scope is the “power” of the scope. This indicates what the shooter is checking out through the scope is amplified times the power aspect of what can typically be seen by human eyes.
Fixed Power Lens Scopes
A single power rifle optic and scope comes with a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not fluctuate considering that it is set from the factory.
Adjustable Power Lens Rifle Optic Info
Variable power rifle scopes can be tweaked between magnified levels. The power adjustment is accomplished by the power ring part of the scope near the back of the scope by the eye bell.
Scope Power Level and Ranges
Here are some suggested scope powers and the distances where they may be effectively used. Highly magnified rifle scope glass will not be as useful as lower magnification level optics considering that too much magnification can be a bad thing. The exact same idea applies to longer distances where the shooter needs increased power to see precisely where to best aim the rifle.
About Lens Finish
All present day rifle optic and scope lenses are coated. Lens coating is an essential element of a rifle when looking into high end rifle optics and scope setups.
HD Versus ED Lenses
Some optic manufacturers additionally use “HD” or high-definition glass finishings that take advantage of different procedures, polarizations, rare earth compounds, and elements to draw out different colors and viewable target visibility through lenses. This high-definition coating is frequently used with greater density glass which reduces light’s potential to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious over things with well defined outlines as light hits the item from various angles.
What to Know About Single Covering Versus Multi-Coating
Different optic lenses can even have different coverings applied to them. All lenses typically have at least some kind of treatment or covering applied to them before they are used in a rifle scope or optic assembly. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently functional in many types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope producer and how much you spent for it. The scope’s maker and cost are signs of the lens quality.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the producer’s lens treatment innovation and the quality of products used in building the rifle scope.
Anti-water Rifle Optic Lens Coating
Water on a scope’s lens doesn’t assist with preserving a clear sight picture through a scope at all. Many top of the line or premium optic manufacturers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It deals with the surface area of the Steiner glass lens so the water molecules can not bind to it or create surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Rifle Optic Mounting Choices
Mounting solutions for scopes are available in a couple of choices. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally come in quick release versions which use throw levers which enable rifle shooters to rapidly mount and remove the optics.
Hex Key Rifle Optic Rings
Standard, clamp design 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 two different rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long distance precision shooting. This type of scope install is excellent for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible design mount. These types of mounts come in handy for rifle platforms which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles or are situationally focused.
Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by triggering fogging and creating residue inside of the scope tube. Many scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another part of preventing the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the glass is less affected by temperature level shifts and pressure distinctions from the outside environment which might possibly permit water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
