Rifle Optic Facts
Rifle scopes permit you to specifically aim a rifle at different targets by lining up your eye with the target over a range. They accomplish this through zoom by utilizing a set of lenses within the scope. The scope’s alignment can be adjusted for consideration of numerous environmental elements like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based upon the sight picture you are viewing through 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 inside and externally on the scope body. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other elements. Learn about the eleven parts of optics.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane an optic has establishes where the reticle or crosshair is located relative to the scopes magnifying adjustments. It simply indicates the reticle is located behind or in front of the magnification lens of the scope. Considering the very best form of rifle glass is dependent on what style of shooting you anticipate undertaking.
Info About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who recognize their aim point “hold over” as well as “lead” ratios for their long gun
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Scope Details
Second focal plane scopes (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 measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots happen within much shorter ranges and proximities
- Shooters who desire a clearer optic picture with less room taken up by the enlarged FFP reticle
Details on Glass Zoom
The amount of zoom a scope supplies is determined by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Scopes
A single power rifle optic comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not change considering that it is a fixed power optic.
Adjustable Power Lens Scope Info
Variable power rifle scopes can be adjusted between magnification levels. These types of scopes will note the zoom level in a format like 2-10×32. These numbers imply the magnification of the scope could be adjusted between 2x and 10x power. This also utilizes the powers in-between 2 and 10. The power shift is achieved using the power ring component of the scope near the rear of the scope by the eye bell.
The Power Level and Range Correlation of Optics
Here are some recommended scope power settings and the distances where they can be efficiently used. Highly magnified scopes will not be as useful as lower magnification level optics due to the fact that too much magnification can be a negative aspect depending on your shooting distance. The same applies to extended distances where the shooter needs enough power to see exactly where to best aim the rifle.
About Rifle Scope Lens Coating
All modern rifle optic lenses are covered. Lens coating is an essential element of a shooting system when buying high end rifle optics and scope setups.
HD Versus ED Rifle Glass Lens Coatings
Some glass companies will also use “HD” or high-definition lense finishings that take advantage of various processes, polarizations, chemicals, and aspects to extract separate color ranges and viewable target visibility through lenses. This high-definition finishing is normally used with more costly high density lens glass which drops light’s opportunity to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration is often visible around objects with hard edges and outlines as light hits the object from certain angles.
Single Finish Versus Multi-Coating
Different optic lenses can even have different finishes applied to them. All lenses usually have at least some kind of treatment or coating applied to them before being used in a rifle scope or optic assembly. This is since the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It needs to have a coating applied to it so that the lens will be efficiently usable in numerous types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can safeguard 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 producer 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 implies the lens has had numerous treatments applied to the surfaces. If a lens receives numerous treatments, it can indicate that a manufacturer is taking several actions to combat different environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This also does not always imply the multi-coated lens is better than a single coated lens. Being “better” depends on the maker’s lens treatment technology and the quality of components used in constructing the rifle scope.
Scope Lens Hydrophobic Finishing
Water on an optic’s lens doesn’t improve maintaining a clear sight picture through an optic in any way. Lots of top of the line or premium scope manufacturers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the surface area of the Steiner optic lens so the H2O molecules can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Options for Mounting Rifle Scopes on Long Guns
Installing solutions for scopes can be found in a couple of choices. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also usually are made in quick release variations which use manual levers which permit rifle operators to quickly install and dismount the glass.
Scope Mounts with Hex Key Rings
Standard, clamp style mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mount rails on the tops of rifles. These types of scope mounts use a pair of independent rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are manufactured for long distance accuracy shooting. This form of scope mount is excellent for rifle systems which need a durable, unfailing mount which will not shift regardless of how much the scope is moved about or jarring the rifle takes. These are the type of mounts you really want to have for a dedicated scope system on a long distance scouting or interdiction firearm which will seldom need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to prevent the hex screw threads from wiggling out after they are installed firmly in place. An example of these rings are the 30mm type made by Vortex Optics. The set normally costs around $200 USD
Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle. Multiple scopes can also be switched out if they all use a complementary designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping the original sighting settings. These kinds of mounts are useful and beneficial for shooting platforms which are moved around a lot, to take off the scope from the rifle for protection, or for sight systems which are employed between a number of rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle scope can destroy a day of shooting and your costly optic by triggering fogging and creating residue within the scope’s tube. Many scopes prevent moisture from getting in the optical tube with a series of sealing O-rings which are water resistant. Typically, these water-resistant scopes can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture content avoidance for standard use rifles, unless you anticipate taking your rifle on a boat and are concerned about the scope still working if it goes over the side and you can still salvage the firearm.
Gas Purged Scope Tubes
Another part of preventing the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the scope is less impacted by temperature alterations and pressure distinctions from the outside environment which may possibly permit water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
