About Rifle Scopes
Rifle scopes enable you to precisely align a rifle at different targets by aligning your eye with the target over a range. They accomplish this through magnifying the target using a series of lenses within the scope. The scope’s positioning can be adjusted for consideration of various natural things like wind speed and elevation to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based on the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes and optics have around eleven parts which are located internally and externally on the optic. These optic pieces include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other components. Learn about the eleven parts of rifle glass.
About Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the best type of rifle optic is based on what type of shooting you plan on doing.
Info About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who understand their target “hold over” and “lead” ratios for their long guns
- Shooters who do not mind the reticle is enlarged and occupies more visual sight room than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have additional time to make ballistic computations
- Shooting where most of the shots occur within shorter ranges and spaces
- Shooters who would like a clearer optic picture without space taken up by the enlarged FFP reticle
The amount of scope magnification you require depends upon the form of shooting you plan to do. Practically every style of rifle optic gives some degree of zoom. The quantity of zoom a scope supplies is established by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the optic is the “power” of the opic. This indicates what the shooter is checking out through the scope is magnified times the power element of what can normally be seen by human eyes.
Info About Fixed Single Power Lens Glass
A single power rifle scope uses 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 type of optic can not adjust considering that it is a fixed power scope.
Variable Power Lens Rifle Scope Info
Variable power rifle scopes can be modified between magnified levels. The power adjustment is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Glass
Here are some suggested scope powers and the ranges where they could be successfully used. High power optics will not be as useful as lower powered scopes given that too much zoom can be a negative aspect depending on your shooting distance. The same concept applies to extended distances where the shooter needs adequate power to see precisely where to properly aim the rifle at the target.
Info on Glass Lens Coatings
All present day rifle optic and scope lenses are layered. Lens coating is a significant aspect of a shooting system when buying high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope makers likewise use “HD” or high-definition lens coatings which use different procedures, chemicals, polarizations, and aspects to draw out a wide range of 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 Glass Lens Finish Versus Multi-Coating
Different optic lenses can likewise have different finishings used to them. All lenses usually have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope developer and how much money you spent for it. The scope’s maker and cost are signs of the lens quality.
Some scope manufacturers similarly make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
Anti-water Scope Lens Finish
Water on a lens doesn’t improve keeping a clear sight picture through a scope at all. Many top of the line or premium scope makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It provides protection for the surface of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Options for Mounting Rifle Optics on Long Guns
Mounting options for scopes are available in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also typically can be found in quick release versions which use throw levers which allow rifle shooters to rapidly install and dismount the optics.
Glass Mounting Solutions with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope mount is excellent for rifles which need a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. If they all use a similar style mount, a number of scopes can also be switched in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining the original sighting settings. These kinds of mounts are useful and convenient for shooting platforms which are carried a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are chosen for use between several rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
About Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your expensive optic by bringing about fogging and developing residue inside of the scope tube. A lot of scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Scope Tubes
Another part of avoiding the accumulation of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the optic is less influenced by temperature alterations and pressure variations from the external 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 decent rifle scope to seek out.
