Optic Info
Rifle scopes allow you to exactly aim a rifle at different targets by lining up your eye with the target over a range. They do this through magnification by making use of a set of lenses within the scope. The scope’s alignment can be adjusted to account for many ecological factors like wind speed and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes have about 11 parts which are arranged within and on the exterior of the scope. These optic pieces include the rifle scope’s body, lenses, windage and elevation dials, focus rings, and other elements. See all eleven parts of scopes.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the best type of rifle scope 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 types of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are minor
- Experienced shooters who know their target “hold over” plus “lead” relationships for their firearms
- Shooters who don’t mind the reticle is bigger and occupies more visual sight area than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick.
- Long distance styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots happen within shorter distances and ranges
- Shooters who want a clearer optic picture with less room taken up by the larger sized FFP reticle
Zoom for Rifle Scopes
The measure of scope magnification you need depends upon the sort of shooting you wish to do. Practically every kind of rifle glass provides some degree of magnification. The quantity of zoom a scope offers is determined by the diameter, density, and curves of the lenses inside of the rifle scope. The magnifying level of the scope is the “power” of the glass. This signifies what the shooter is looking at through the scope is amplified times the power aspect of what can normally be seen by human eyes.
Single Power Lens Glass
A single power rifle scope uses a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not fluctuate because it is a fixed power optic.
Adjustable Power Lens Glass Info
Variable power rifle scopes can be changed between magnification increments. It will list the zoom level in a format such as 2-10×32. These numbers indicate the magnification of the scope can be changed in between 2x and 10x power. This always involves the powers in-between 2 and 10. The power adjustment is achieved by employing the power ring part of the scope near the back of the scope by the eye bell piece.
The Power Level and Range Correlation of Glass
Here are some advised scope power levels and the distances where they may be successfully used. Remember that higher power scopes and optics will not be as practical as lower magnification level scopes because excessive zoom can be a negative thing in certain situations. The exact same concept applies to longer ranges where the shooter needs to have sufficient power to see precisely where to properly aim the rifle at the target.
Rifle Glass Lens Covering
All contemporary rifle scope lenses are covered. Lens finish is a significant aspect of a shooting system when considering high end rifle optics and scope systems.
HD Versus ED Lens Coatings
Some scope brands likewise use “HD” or high-definition lens finishings which use various processes, aspects, polarizations, and chemicals to draw out various colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Details on Single Finish Versus Multi-Coating
Different scope lenses can even have different coatings applied to them. All lenses typically have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic. This is since the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It must have a finishing applied to it so that it will be efficiently usable in lots of kinds of environments, degrees of light (full VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer 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 “much better” depends on the producer’s lens treatment innovation and the quality of products used in building the rifle scope.
Hydrophobic Glass Lens Covering
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic anti-water covering.
Scope Installing Options
Mounting approaches for scopes are available in a few choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also typically are made in quick release variations which use throw levers which permit rifle shooters to rapidly install and remove the optics.
Scope Mounts with Hex Key Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope install is great for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. If they all use a similar design mount, multiple scopes can often be swapped out on the range. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving accuracy. These types of mounts come in beneficial for rifles which are carried a lot, to take off the scope from the rifle for protection, or for optics which are adopted between several rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day of shooting and your expensive optic by causing fogging and developing residue inside of the scope tube. The majority of scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Info on Rifle Scope Tube Gas Purging
Another part of avoiding the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is already taken up by the gas, the glass is less affected by temperature level shifts and pressure differences from the outside environment which may potentially enable 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.
