Rifle Scope Information
Rifle scopes permit you to specifically aim a rifle at various targets by aligning your eye with the target at range. They do this through magnification using a set of lenses inside the scope. The scope’s positioning can be adapted to account for various ecological aspects like wind speed and elevation to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle optics have around 11 parts which are arranged within and outside of the scope. These scope parts include the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
About 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 connection with the optic’s magnifying adjustments. It actually suggests the reticle is behind or ahead of the magnification lens of the optic. Picking the most beneficial kind of rifle scope depends on what variety of shooting or hunting you anticipate doing.
First Focal Plane Optic Facts
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where estimations are minor
- Experienced shooters who recognize their aim point “hold over” and “lead” relationships for their firearm
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Glass Details
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 would be 1/5th of the non “zoom” tick reticle measurement.
- Far away styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots happen within shorter spaces and ranges
- Shooters who like a clearer optic picture without room used up by the enlarged FFP reticle
Rifle Optic Magnification
The amount of zoom a scope supplies is figured out 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.
About Fixed Power Lens Rifle Glass
A single power rifle optic and scope uses a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not change considering that it is fixed.
Variable Power Lens Rifle Optic Facts
Variable power rifle scopes use variable power levels. The power modification is performed by the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some recommended scope powers and the ranges where they can be effectively used. Keep in mind that higher power glass will not be as effective as lower magnification level glass because excessive magnification can be a detractor. The exact same concept relates to longer distances where the shooter needs to have increased power to see exactly where to properly aim the rifle at the target.
Rifle Optic Lens Covering
All modern-day rifle optic lenses are coated. Lens coating can be a vital element of a shooting system when buying high end rifle optics and scope setups.
HD Versus ED Rifle Glass Lens Coatings
Some scope manufacturers also use “HD” or high-definition lens finishes which use various procedures, chemicals, polarizations, and elements to draw out various colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Glass
Various optic lenses can also have various finishings applied to them. All lenses normally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. 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 must have a covering put on it so that it will be efficiently functional in many types of environments, degrees of sunshine (full VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while lowering glare and other less helpful 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 producers similarly make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle scope.
About Hydrophobic Finish
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Numerous top of the line and military grade scope makers will coat their lenses with a hydrophobic or hydrophilic covering.
Scope Mounting Alternatives
Installing options for scopes can be found in a couple of options. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also generally can be found in quick release variations which use toss levers which permit rifle operators to rapidly install and dismount the optics.
Hex Key Glass Ring Mounts
Standard, clamp-on design mounting optic rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use two separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are designed for long distance precision shooting. This form of scope mount is good for rifle systems which need a long lasting, unfailing mount which will not change no matter just how much the scope is moved or abuse the rifle takes. These are the style of mounts you should get for a devoted scope system on a far away hunting or hard target interdiction rifle that will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on screws to prevent the hex screw threads from backing out after they are mounted tightly in position. An example of these rings are the 30mm style from the Vortex Optics company. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle. If they all use a similar design mount, several scopes can often be swapped out in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten tightly to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining accuracy. These types of mounts are useful and practical for rifles which are hauled around a lot, to take off the scope glass from the rifle for protection, or for sight systems which are adopted in between numerous rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It normally costs around $250 USD
Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your costly optic by inducing fogging and generating residue within the scope tube. Many scopes protect against humidity from entering the optical tube with a series of sealing O-rings which are water resistant. Normally, these water-resistant scopes can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough wetness prevention for conventional use rifles for hunting and sporting purposes, unless you intend on taking your rifle on a boat and are concerned about the optic still working if it is submerged in water and you can still recover the firearm.
Gas Purged Rifle Optic Tubes
Another component of preventing the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the optic is less influenced by condition alterations and pressure variations from the external environment which could possibly enable water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
