Information About Scopes
Rifle scopes permit you to specifically align a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnification by utilizing a set of lenses inside the scope. The scope’s positioning can be adapted to take into account separate environmental things like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle optics have around eleven parts which are located inside and on the exterior of the scope. These optic pieces include the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other elements. See all eleven parts of a rifle scope.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has determines where the reticle or crosshair is located in connection with the scopes zoom. It actually suggests the reticle is located behind or ahead of the magnifying lens of the optic. Choosing the most ideal form of rifle optic is based on what type of hunting or shooting you anticipate doing.
First Focal Plane Glass
First focal plane optics (FFP) feature the reticle ahead of the magnification lens. This induces the reticle to increase in size based on the amount of magnification being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at one hundred yards by using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are marginal
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” correlations for their rifles
- Shooters who don’t mind the reticle is bigger and uses up more visual sight room than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. This induces the reticle to remain at the same size relative to the amount of zoom being used. The effect is that the reticle measurements shift based upon the magnification applied to shoot over greater ranges considering that the reticle markings represent distinct increments which fluctuate with the magnification level. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular types of optics are beneficial for:
- Long distance styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots occur within shorter spaces and ranges
- Shooters who select a clearer optic sight picture with less space used up by the bigger FFP reticle
Magnification for Scopes
The measure of scope magnification you require depends on the type of shooting you desire to do. Just about every style of rifle scope offers some degree of zoom. The volume of magnification a scope offers is determined by the dimension, density, and curvatures of the lens glass within the rifle scope. The zoom of the scope is the “power” of the glass. This suggests what the shooter is aiming at through the scope is magnified times the power factor of what can usually be seen by human eyes.
Fixed Single Power Lens Rifle Scopes
A single power rifle scope uses a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust because it is fixed.
About Adjustable Power Lens Glass
Variable power rifle scopes can be modified between magnified settings. The power change is achieved by using the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range
Here are some suggested scope power levels and the ranges where they could be successfully used. Highly magnified scopes will not be as beneficial as lower magnification level optics considering that too much magnification can be a negative aspect depending on your shooting distance. The same relates to extended ranges where the shooter needs increased power to see where to properly aim the rifle at the target.
Lens Finishing for Scopes
All modern rifle scope lenses are covered in special coatings. There are different types and qualities of coverings. Lens finishing is an important aspect of a rifle’s setup when thinking about high end rifle optics and targeting units. The glass lenses are among the most essential parts of the optic given that they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens exterior and helps with anti glare capabilities from excess direct sunlight and color visibility.
HD Versus ED Lens Coatings
Some scope brands likewise use “HD” or high-definition lens coatings which use different techniques, polarizations, chemicals, and aspects to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finish Versus Multi-Coating for Rifle Glass
Different optic lenses can even have various coatings applied to them. All lenses normally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It needs to have a finishing placed on it so that it will be optimally functional in numerous types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while decreasing 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 maker and how much you paid for it.
Some scope makers 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 developing the rifle scope.
Hydrophobic Lens Covering
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Many top of the line and military grade optic makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Options for Mounting Rifle Scopes on Long Guns
Mounting options 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 usually come in quick release variations which use throw levers which enable rifle shooters to rapidly install and remove the scope.
Hex Key Rifle Scope Rings
Standard, clamp-on style mounting scope rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use two individual rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are created for far away accuracy shooting. This form of scope mount is ideal for rifles which need a resilient, hard use mount which will not shift despite just how much the scope is moved or abuse the rifle takes. These are the type of mounts you really want to have for a faithful optics system on a long distance hunting or tournament firearm that will almost never need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to stop the hex screw threads from backing out after they are mounted safely in place. An example of these rings are the 30mm type made by the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly take off a scope and attach it to a different rifle. Several scopes can even be switched out if they all use a similar style mount. These types of mounts are handy for rifles which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between numerous rifles or are situationally focused.
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by triggering fogging and developing residue inside of the scope tube. A lot of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Details on Scope Tube Gas Purging
Another part of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the optic is less affected by temperature alterations and pressure differences from the outdoor environment which may potentially enable water vapor to leak 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.
