Scope Info
Rifle scopes enable you to precisely aim a rifle at different targets by aligning your eye with the target over a distance. They do this through magnification by using a series of lenses inside the scope. The scope’s positioning can be dialed in to take into account numerous ecological aspects like wind and elevation increases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle optics have around 11 parts which are located inside and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other parts. See all eleven parts of a rifle scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Going for the optimal type of rifle glass is based on what type of shooting you plan to do.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are small
- Experienced shooters who recognize their aim point “hold over” and also “lead” correlations for their firearms
- Shooters who do not mind the reticle is enlarged and occupies more visual eyesight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 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 shots happen within much shorter ranges and spaces
- Shooters who would like a clearer optic picture with less space taken up by the bigger FFP reticle
Zoom for Rifle Glass
The quantity of scope magnification you need on your optic is based on the sort of shooting you like to do. Virtually every style of rifle scope provides some degree of magnification. The amount of magnification a scope offers is identified by the size, thickness, and curvatures of the lens glass within the rifle optic. The magnification of the scope is the “power” of the glass. This suggests what the shooter is observing through the scope is amplified times the power factor of what can usually be seen by human eyes.
Info About Fixed Power Lens Scopes
A single power rifle optic and scope comes with a magnification 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 type of optic can not adjust given that it is a set power scope.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification degree in a format like 2-10×32. These numbers imply the zoom of the scope can be changed between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power modification is accomplished using the power ring component of the scope near the rear of the scope by the eye bell piece.
Scope Power Level and Range Correlation
Here are some advised scope power settings and the ranges where they can be effectively used. Consider that high power optics will not be as practical as lower powered optics since increased magnification can be a detractor. The exact same idea relates to longer distances where the shooter needs sufficient power to see precisely where to best aim the rifle at the target.
About Rifle Optic Lens Finish
All modern rifle optic lenses are covered in special coatings. There are various types and qualities of glass lens finishings. Lens covering is an essential aspect of a rifle when thinking of luxury rifle optics and scope units. The glass lenses are among the most crucial pieces of the glass given that they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses protects the lens surface area and also helps with anti glare from excess natural light and color recognition.
HD Versus ED Lens Coatings
Some scope brands also use “HD” or high-definition lens finishings which use various techniques, chemicals, components, and polarizations to draw out various colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Glass Lens Single Covering Versus Multi-Coating
Different optic lenses can also have different coatings used to them. All lenses usually have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can protect 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 covered lens depends on the scope company and the amount you paid for it. Both the manufacturer and amount are indications of the lens quality.
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 technology and the quality of materials used in constructing the rifle scope.
Details on Anti-water Finishing
Water on an optic’s lens doesn’t support maintaining a clear sight picture through a scope in any way. Many top of the line and premium scope makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It provides protection for the surface of the Steiner optic lens so the H2O molecules can not bind to it or develop surface tension. The result is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Choices for Installing Rifle Optics on Long Guns
Mounting options for scopes can be found in a couple of choices. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also normally come in quick release variations which use toss levers which permit rifle shooters to rapidly install and remove the glass.
Optic Mounting Solutions with Hex Key Rings
Basic, clamp-on design mounting optic rings use hex head screws to position to the flattop style Picatinny scope mount rails on the tops of rifles. These forms of scope mounts use two separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are designed for long distance accuracy shooting. This kind of scope mount is effective for rifles which need a resilient, unfailing mount which will not change no matter how much the scope is moved about or abuse the rifle takes. These are the design of mounts you really want to have for a faithful scope setup on a long distance hunting or sniper competition rifle that will pretty much never need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to prevent the hex screw threads from backing out after they are mounted securely in place. An example of these rings are the 30mm type made by Vortex Optics. The set usually costs around $200 USD
Rifle Glass Mounting Solutions 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. A wide range of scopes can also be swapped out if they all use a similar style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining accuracy. These types of mounts come in beneficial for rifles which are transferred between vehicles a lot, to remove the scope glass from the rifle for protection, or for scopes which are used in between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
About Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day on the range and your highly-priced optic by triggering fogging and producing residue within the scope tube. Many scopes protect against humidity from entering the scope tube with a series of sealing O-rings which are water resistant. Usually, these water-resistant scopes can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample wetness prevention for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle boating and are worried about the scope still working if it falls overboard and you can still salvage the rifle.
Optic Gas Purging
Another component of avoiding the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the scope is less influenced by temperature level shifts and pressure differences from the external environment which could potentially enable water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
