All About Rifle Optics
Rifle scopes allow you to specifically align a rifle at various targets by lining up your eye with the target at range. They accomplish this through zoom by using a series of lenses within the scope. The scope’s positioning can be adjusted to take into account separate ecological things like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based on the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle scopes have about 11 parts which are located within and externally on the scope body. These parts include the rifle scope’s body, lenses, elevation turrets, focus rings, and other components. Learn about the eleven parts of scopes.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The sort of focal plane a scope has identifies where the reticle or crosshair lies in relation to the scopes magnifying adjustments. It actually means the reticle is situated behind or before the magnification lens of the scope. Deciding on the most reliable kind of rifle scope depends upon what variety of hunting or shooting you anticipate doing.
First Focal Plane Glass Info
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 estimations are low
- Experienced shooters who know their aim point “hold over” and also “lead” correlations for their long guns
- Shooters who don’t mind the reticle is bigger and requires more visual sight area than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Far away kinds of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and proximities
- Shooters who prefer a clearer optic picture without area used up by the larger size FFP reticle
Ins and Outs of Rifle Optic Magnification
The quantity of magnification a scope provides is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Rifle Glass Info
A single power rifle optic or scope uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not change given that it is a fixed power scope.
Variable Power Lens Rifle Glass Info
Variable power rifle scopes use variable power levels. The power modification is handled by using the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Optic Power and Range Correlation
Here are some suggested scope power levels and the ranges where they can be efficiently used. High power rifle scope glass will not be as effective as lower magnification optics because too much magnification can be a negative aspect depending on your shooting distance. The exact same idea relates to longer ranges where the shooter needs to have sufficient power to see where to best aim the rifle at the target.
Info on Lens Coverings
All contemporary rifle scope lenses are covered in special coatings. There are different types and qualities of glass lens coatings. When researching high end rifle optical units, Lens finish can be a critical component of defining the capability of the rifle. The lenses are among the most essential pieces of the glass considering that they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses shields the lens exterior as well as helps with anti glare from refracted sunshine and color discernibility.
HD Versus ED Lenses
Some scope brands also use “HD” or high-definition lens finishings which use various techniques, polarizations, chemicals, and aspects to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Coating Versus Multi-Coating
Various optic lenses can even have different coverings applied to them. All lenses usually have at least some kind of treatment or finishing applied to them before being used in a rifle scope or optic. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a coating placed on it so that the lens will be efficiently usable in numerous types of environments, degrees of sunlight (full light 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 producer and how much you paid for it.
Some scope manufacturers similarly make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the producer’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Hydrophobic Lens Coatings
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade optic companies will coat their lenses with a hydrophobic or hydrophilic finish.
Alternatives for Mounting Scopes on Long Guns
Mounting solutions for scopes can be found in a few choices. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually are made in quick release variations which use toss levers which enable rifle shooters to quickly install and dismount the optics.
Hex Key Glass Rings
Standard, clamp-on design mounting scope rings use hex head screws to install to the flattop style Picatinny scope mount rails on rifles. These varieties of scope mounts use two detached rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are made for far away precision shooting. This kind of scope mount is good for rifle systems which are in need of a long lasting, unfailing mount which will not move regardless of how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should have for a devoted optics setup on a long distance scouting or hard target interdiction firearm that will seldom need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to stop the hex screw threads from wiggling out after they are installed tightly in position. An example of these mounting rings are the 30mm type from Vortex Optics. The set usually costs around $200 USD
Rifle Glass Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, several scopes can also be switched out. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping precision. These kinds of mounts are useful and handy for shooting platforms which are transferred between vehicles a lot, to take off the scope glass from the rifle for protection, or for optics which are adopted between numerous rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Moisture inside your rifle scope can destroy a day of shooting and your pricey optic by bringing about fogging and developing residue inside of the scope tube. Many scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
About Rifle Glass Tube Gas Purging
Another element of avoiding the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is currently taken up by the gas, the scope is less impacted by climate changes and pressure differences from the external environment which may possibly enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
