Rifle Scope Facts
Rifle scopes enable you to precisely align a rifle at different targets by lining up your eye with the target at range. They do this through magnifying the target by utilizing a set of lenses within the scope. The scope’s positioning can be dialed in for consideration of separate ecological factors like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based upon the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the target. Many contemporary rifle scopes and optics have around eleven parts which are found within and on the exterior of the optic. These optic pieces consist of the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other elements. Learn about the eleven parts of rifle scopes.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has establishes where the reticle or crosshair is located in relation to the scopes magnifying adjustments. It simply suggests the reticle is located behind or in front of the magnifying lens of the scope. Deciding upon the most beneficial sort of rifle scope depends on what sort of shooting you plan on undertaking.
Info on First Focal Plane Optics
First focal plane scopes (FFP) feature the reticle ahead of the zoom lens. This induces the reticle to increase in size based on the amount of magnification being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified range. As an example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who recognize their aim point “hold over” plus “lead” ratios for their rifles
- Shooters who do not mind the reticle is bigger and requires more visual sight area than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane glass (SFP) come with the reticle behind the zoom lens. This causes the reticle to remain at the same dimensions in connection with the amount of magnification being used. The outcome is that the reticle dimensions adjust based upon the zoom used to shoot over longer ranges since the markings represent distinct increments which change with the magnification. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These sorts of scopes work for:
- Long distance types of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots take place within shorter spaces and ranges
- Shooters who choose a clearer optic sight picture without area taken up by the bigger FFP reticle
Glass Zoom
The quantity of zoom a scope supplies is identified by the size, 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 Rifle Glass Facts
A single power rifle optic or scope will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate because it is a fixed power scope.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes use variable power levels. The power change is handled by using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some suggested scope power settings and the ranges where they may be successfully used. Keep in mind that higher power scopes will not be as practical as lower magnification level scopes because too much zoom can be a negative thing in certain situations. The same idea goes for extended ranges where the shooter needs to have increased power to see precisely where to properly aim the rifle.
Info on Optic Lens Coverings
All modern rifle scope and optic lenses are layered. There are different types and qualities of glass coatings. When shopping for high end rifle scope systems, Lens finishing can be a crucial component of a rifle. The lenses are among the most critical pieces of the glass considering that they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses safeguards the lens exterior and also helps with anti glare from refracted light and color presence.
HD Versus ED Lens Coatings
Some rifle scope makers also use “HD” or high-def lens finishes that make the most of different procedures, chemicals, elements, and polarizations to draw out numerous color ranges and viewable target definition through the lens. This HD covering is frequently used with more costly, high density glass which decreases light’s opportunity to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” signifying extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration may be noticeable over objects with hard outlines as light hits the object from specific angles.
What to Know About Single Covering Versus Multi-Coating
Different optic lenses can also have different finishes applied to them. All lenses generally have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers similarly make it a point to specify if their optic lenses are coated or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Hydrophobic Lens Finish
Water on a lens doesn’t improve maintaining a clear sight picture through a scope in any way. Numerous top of the line or premium scope makers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It provides protection for the exterior of the Steiner scope lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Rifle Optic Installation Choices
Installing solutions for scopes are available in a few options. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also normally are made in quick release variations which use manual levers which enable rifle operators to quickly mount and dismount the scopes.
Hex Key Rifle Optic Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range accuracy shooting. This type of scope mount is fine for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be switched out if they all use a similar design mount. These types of mounts come in handy for rifles which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between several rifles or are situationally focused.
Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can mess up a day on the range and your costly optic by triggering fogging and making residue within the scope’s tube. Many optics protect against humidity from getting in the optical tube with a system of sealing O-rings which are water resistant. Usually, these water-resistant optics can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture avoidance for basic use rifles, unless you plan on taking your rifle sailing and are concerned about the scope still performing if it goes over the side and you can still salvage the firearm.
Gas Purged Rifle Scope Tubes
Another element of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is currently occupied by the gas, the optic is less impacted by climate alterations and pressure distinctions from the outdoor environment which could potentially allow water vapor to seep 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.
