What You Need to Know About Rifle Scopes
Rifle scopes allow you to specifically align a rifle at various targets by aligning your eye with the target at range. They do this through zoom by employing a set of lenses inside the scope. The scope’s alignment can be adapted for the consideration of separate environmental things 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 land based upon the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended point of impact. Most modern rifle scopes have about eleven parts which are found inside and externally on the scope. These scope parts include the rifle scope’s body, lenses, modification dials, objective focus rings, and other components. See all eleven parts of a rifle scope.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the finest type of rifle scope depends on what type of shooting you plan on doing.
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, far away kinds of shooting
- Shooting circumstances where computations are minimal
- Experienced shooters who recognize their aim point “hold over” and also “lead” correlations for their firearms
- Shooters who do not mind the reticle is bigger and takes up more visual sight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane glass (SFP) come with the reticle behind the magnification lens. This causes the reticle to stay at the very same size in connection with the amount of magnification being used. The outcome is that the reticle measurements alter based on the magnification used to shoot over lengthier distances given that the reticle markings present various increments which vary with the zoom. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular varieties of scopes are beneficial for:
- Long distance styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots happen within much shorter proximities and ranges
- Shooters who would like a clearer optic sight picture without space used up by the larger sized FFP reticle
Glass Magnification
The quantity of zoom a scope provides 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 Single Power Lens Scope Details
A single power rifle scope will have a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate given that it is a fixed power optic.
Adjustable Power Lens Rifle Optic Info
Variable power rifle scopes have adjustable power. It will list the magnification degree in a configuration such as 2-10×32. These numbers suggest the magnification of the scope can be changed between 2x and 10x power. This additionally includes the powers in-between 2 and 10. The power adjustment is accomplished by working with the power ring component of the scope near the rear of the scope by the eye bell piece.
The Power and Range Correlation of Rifle Optics
Here are some recommended scope power levels and the distances where they may be successfully used. Highly magnified rifle scope glass will not be as efficient as lower magnification glass since too much zoom can be a negative aspect depending on your shooting distance. The same concept goes for extended distances where the shooter needs to have sufficient power to see precisely where to properly aim the rifle at the target.
Lens Coating for Rifle Glass
All top of the line rifle optic and scope lenses are coated. Lens finish can be a vital aspect of a rifle’s setup when looking at high end rifle optics and scope systems.
About Lens Coatings – HD Versus ED
Some rifle scope manufacturers also use “HD” or high-def lense finishings that use various processes, polarizations, elements, and chemicals to enhance various color ranges and viewable target definition through lenses. This high-definition coating is typically used with more costly high density glass which brings down light’s potential to refract through the lens glass. Some scope corporations use “HD” to describe “ED” signifying extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around objects with hard edges and shapes as light hits the item from certain angles.
Single Covering Versus Multi-Coating
Different optic lenses can also have various coatings applied to them. All lenses generally have at least some type of treatment or coating applied to them before being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated 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 means the lens has numerous treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can prove that a maker is taking numerous steps to fight different natural elements like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This additionally doesn’t always indicate the multi-coated lens will perform much better than a single coated lens. Being “better” depends upon the producer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Scope Lens Anti-water Coating
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic coating.
Options for Installing Scopes on Firearms
Installing solutions for scopes come in a couple of options. There are the basic scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also normally are made in quick release variations which use throw levers which allow rifle operators to quickly mount and remove the scopes.
Hex Key Glass Rings
Standard, clamp-on style mounting scope rings use hex head screws to position to the flattop style Picatinny scope mount rails on the tops of rifles. These forms of scope mounts use a pair of individual rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are created for long distance precision shooting. This kind of scope mount is great for rifle systems which are in need of a long lasting, rock solid mount which will not shift despite just how much the scope is moved about or abuse the rifle takes. These are the design of mounts you should get for a dedicated optics setup on a reach out and touch someone scouting or sniper competition firearm which will almost never need to be modified or recalibrated. Blue 242 Loctite threadlocker can additionally be used to protect against the hex screws from backing out after they are installed firmly in position. An example of these mounting rings are the 30mm type from Vortex Optics. The set typically costs around $200 USD
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be switched out if they all use a compatible style mount. These types of mounts are convenient for rifle platforms which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are used in between several rifles or are situationally focused.
Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your pricey optic by bringing about 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 waterproof.
Rifle Glass Gas Purging
Another part of preventing the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is already taken up by the gas, the scope is less affected by condition changes and pressure differences from the outside environment which could potentially permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
