Rifle Optic Details
Rifle scopes permit you to precisely align a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnifying the target by employing a series of lenses within the scope. The scope’s positioning can be dialed in for consideration of many ecological factors like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based on the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the target. The majority of modern rifle scopes and optics have around eleven parts which are located internally and on the exterior of the scope. These parts consist of the rifle scope’s body, lenses, elevation dials, objective focus rings, and other parts. Learn about the eleven parts of glass.
About Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going 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) include the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting situations where computations are marginal
- Experienced shooters who understand their aim point “hold over” plus “lead” correlations for their firearm
- Shooters who do not mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick 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 of the shots happen within much shorter ranges and proximities
- Shooters who desire a clearer optic sight picture without room taken up by the enlarged FFP reticle
Rifle Glass Magnification
The amount of zoom a scope offers is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info About Fixed Power Lens Rifle Scopes
A single power rifle scope uses a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not change because it is a fixed power optic.
About Variable Power Lens Rifle Scopes
Variable power rifle scopes can be tweaked between magnified settings. The power adjustment is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power Level and Range Correlation
Here are some advised scope power settings and the ranges where they may be effectively used. Highly magnified optics will not be as useful as lower magnification optics since too much magnification can be a bad thing. The very same idea relates to longer distances where the shooter needs to have adequate power to see where to best aim the rifle at the target.
Lens Finish for Rifle Optics
All modern-day rifle scope lenses are layered. There are different types and qualities of glass lens finishes. When looking at high end rifle targeting devices, Lens covering can be a significant element of defining the capability of the rifle. The lenses are among the most essential pieces of the scope as they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses shields the lens surface as well as helps with anti glare capabilities from refracted light and color exposure.
HD Versus ED Lens Coatings
Some rifle scope manufacturers additionally use “HD” or high-definition glass finishings which make the most of different procedures, chemical applications, polarizations, and elements to extract different colors and viewable target definition through lenses. This high-def covering is frequently used with higher density glass which lowers light’s ability to refract through the lens glass. Some scope corporations use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration is often visible over items with defined shapes as light hits the item from various angles.
Single Coating Versus Multi-Coating for Optics
Different scope lenses can even have various finishes applied to them. All lenses normally have at least some kind of treatment or coating applied to them before being used in a rifle scope or optic. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally usable in many kinds of environments, degrees of light (full VS shade), 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 decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope designer and the amount you spent for it. Both the make and cost are signs of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in building the rifle scope.
Rifle Glass Lens Hydrophobic Covering
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Many top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Scope Installation Options
Installing options for scopes are available in a few options. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also normally can be found in quick release variations which use throw levers which allow rifle shooters to rapidly install and remove the glass.
Hex Key Rifle Optic 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 made from 7075 T6 billet aluminum which is developed for long distance precision shooting. This type of scope install is fine for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Scope Mounting Solutions with Quick-Release Cantilever Rings
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 compatible design mount. These types of mounts are handy for rifles which are carried a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between several rifles or are situationally focused.
Info on Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your pricey optic by triggering fogging and producing residue inside of the scope tube. Most scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Details on Rifle Scope Tube Gas Purging
Another component of preventing the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the scope is less impacted by climate alterations and pressure variations from the outside environment which could possibly allow water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
