Rifle Scope Information
Rifle scopes permit you to precisely aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnification by utilizing a set of lenses within the scope. The scope’s positioning can be dialed in to account for various natural elements like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based on the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle scopes have around 11 parts which are located within and outside of the optic. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other parts. See all eleven parts of a scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane a scope has decides where the reticle or crosshair lies in connection with the optic’s magnifying adjustments. It literally suggests the reticle is situated behind or ahead of the magnification lens of the scope. Looking for the best form of rifle glass is dependent on what variety of shooting or hunting you anticipate undertaking.
Info on First Focal Plane Glass
First focal plane scopes (FFP) feature the reticle before the magnifying lens. This triggers the reticle to increase in size based on the level of magnification being used. The outcome is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at 100 yards by using 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who have an idea for their target “hold over” and also “lead” relationships for their weapon
- Shooters who do not mind the reticle is bigger and occupies more visual sight area than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification lens. This induces the reticle to remain at the exact same overall size in relation to the amount of magnification being used. The result is that the reticle dimensions shift based on the magnification chosen to shoot over lengthier distances because the markings present different increments which vary with the magnification. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular sorts of scopes are convenient for:
- Far away styles of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots happen within much shorter distances and ranges
- Shooters who desire a clearer optic sight picture with less area used up by the bigger FFP reticle
Zoom for Glass
The level of scope magnification you need on your optic depends on the style of shooting you choose to do. Nearly every style of rifle scope gives some degree of zoom. The level of zoom a scope delivers is identified by the diameter, thickness, and curves of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the opic. This means what the shooter is looking at through the scope is amplified times the power factor of what can normally be seen by human eyes.
About Fixed Power Lens Optics
A single power rifle scope comes with a magnification number designator like 4×32. This indicates 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 since it is set from the factory.
Info About Variable Power Lens Rifle Glass
Variable power rifle scopes can be adjusted between magnification power levels. It will list the zoom degree in a configuration like 2-10×32. These numbers indicate the magnification of the scope could be set between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power modification is achieved using the power ring component of the scope near the rear of the scope by the eye bell piece.
Scope Power Level and Ranges
Here are some suggested scope power levels and the distances where they may be efficiently used. Highly magnified rifle scope glass will not be as efficient as lower magnification level scopes since too much magnification can be a negative aspect depending on your shooting distance. The exact same idea applies to longer distances where the shooter needs sufficient power to see precisely where to best aim the rifle at the target.
Rifle Optic Lens Coating
All contemporary rifle glass lenses are covered. Lens coating is an important element of a shooting platform when thinking about high end rifle optics and scope systems.
ED Versus HD Scopes
Some optic producers even use “HD” or high-definition lens finishings which employ different processes, polarizations, components, and chemicals to enhance separate color ranges and viewable target visibility through the lens. This HD covering is often used with increased density lens glass which lowers light’s capability to refract through the lens glass. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration may be noticeable over items with well defined shapes as light hits the item from certain angles.
Single Rifle Scope Lens Coating Versus Multi-Coating
Different optic lenses can even have different finishings applied to them. All lenses usually have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic assembly. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It needs to have a finishing placed on it so that the lens will be optimally functional in numerous kinds of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope designer and how much money you spent paying for it. Both are indications of the lens quality.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Anti-water Lens Coating
Water on a lens does not help with preserving a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic coating.
Rifle Glass Mounting Alternatives
Installing solutions for scopes come 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 different kinds of mounts also normally can be found in quick release versions which use toss levers which permit rifle operators to quickly mount and remove the glass.
Hex Key Rifle Scope Rings
Normal, 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 often made from 7075 T6 billet aluminum which is developed for long distance accuracy shooting. This type of scope mount 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 abused.
Rifle Glass Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope and attach it to a different rifle. Several scopes can even be swapped out if they all use a similar style mount. These types of mounts come in handy for long guns 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 several rifles or are situationally focused.
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle scope can wreck a day on the range and your expensive optic by inducing fogging and making residue inside of the scope’s tube. Many scopes prevent wetness from going into the optical tube with a system of sealing O-rings which are water resistant. Normally, these optics can be submerged 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 common use rifles, unless you intend on taking your rifle aboard watercrafts and are worried about the optic still functioning if it falls overboard and you can still rescue the gun.
Info Around Rifle Optic Tube Gas Purging
Another element of preventing the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the glass is less altered by climate shifts and pressure distinctions from the outside environment which might potentially permit 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 look for.
