Rifle Scope Information
Rifle scopes allow you to specifically align a rifle at various targets by lining up your eye with the target at range. They do this through magnification using a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of separate natural considerations like wind speed and elevation to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit 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. A lot of contemporary rifle scopes have about 11 parts which are found within and externally on the scope. These scope parts consist of the rifle scope’s body, lenses, modification dials, objective focus rings, and other elements. Learn about the eleven parts of rifle glass.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane a scope has identifies where the reticle or crosshair lies in relation to the scopes magnification. It literally means the reticle is located behind or before the magnification lens of the scope. Deciding upon the very best kind of rifle optic is dependent on what style of hunting or shooting you intend on doing.
Info About First Focal Plane Optics
First focal plane glass (FFP) include the reticle ahead of the magnifying lens. This causes the reticle to increase in size based upon the amount of magnification being used. The result is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at one hundred yards by using 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are minimal
- Experienced shooters who know their target “hold over” plus “lead” correlations for their long guns
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the magnification 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.
- Long distance kinds of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots occur within much shorter ranges and spaces
- Shooters who select a clearer optic sight picture without area used up by the enlarged FFP reticle
Details on Rifle Optic Zoom
The quantity of zoom a scope provides is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Optic Info
A single power rifle optic comes with a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not adjust considering that it is a fixed power scope.
Variable Power Lens Rifle Glass Info
Variable power rifle scopes use enhanced power. The power adjustment is accomplished by using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Glass
Here are some advised scope power settings and the ranges where they could be effectively used. Consider that high power scopes and optics will not be as efficient as lower magnification level scopes since increased magnification can be a detractor. The same applies to extended distances where the shooter needs to have enough power to see exactly where to best aim the rifle at the target.
Details on Lens Finishes
All cutting-edge rifle glass lenses are coated. Lens finishing is an important element of a shooting platform when looking at high end rifle optics and scope systems.
About Rifle Optic Lens Coatings – HD Versus ED
Some scope manufacturers also use “HD” or high-definition lens coatings which use various techniques, elements, chemicals, and polarizations to draw out various colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Coating Versus Multi-Coating for Rifle Optics
Different optic lenses can also have various finishings used to them. All lenses generally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can shield 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 upon the scope manufacturer and how much you paid for it. The scope’s maker and cost are signs of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Anti-water Lens Finishing
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Many top of the line and military grade optic makers will coat their lenses with a hydrophilic or hydrophobic finishing which is water repellent.
Choices for Mounting Optics on Firearms
Mounting solutions for scopes come in a couple of choices. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also usually come in quick release variations which use manual levers which permit rifle shooters to rapidly install and dismount the glass.
Hex Key Glass Ring Mounting Solutions
Standard, clamp type mounting scope rings use hex head screws to position to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a pair of detached rings to support the optic, and are normally made from 7075 T6 billet aluminum which are made for long distance accuracy shooting. This form of scope mount is exceptional for rifles which need a long lasting, rock solid mount which will not shift regardless of how much the scope is moved or jarring the rifle takes. These are the type of mounts you want for a devoted scope system on a reach out and touch someone scouting or tournament rifle which will hardly ever need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on the screws to protect against the hex screw threads from wiggling out after they are installed tightly in position. An example of these rings are the 30mm type made by the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be switched out if they all use a compatible design mount. These types of mounts come in handy for long guns which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between several rifles or are situationally focused.
Info on Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your costly optic by triggering fogging and developing residue inside of the scope tube. Many scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are waterproof.
Rifle Scope Gas Purging
Another element of preventing the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the scope is less influenced by condition alterations and pressure variations from the external environment which may potentially allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
