Optic Info
Rifle scopes enable you to specifically align a rifle at various targets by aligning your eye with the target over a distance. They do this through magnifying the target by employing a set of lenses within the scope. The scope’s alignment can be adjusted to account for various ecological elements like wind and elevation increases to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the target. Many contemporary rifle optics have around 11 parts which are arranged within and externally on the scope. These scope parts include the rifle scope’s body, lenses, windage dials, objective focus rings, and other elements. Learn about the eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the optimal type of rifle glass depends on what type of shooting you plan on doing.
First Focal Plane Glass Details
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are low
- Experienced shooters who understand their aim point “hold over” and “lead” equations for their long guns
- Shooters who do not mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle behind 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.
- Far away types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots happen within much shorter spaces and ranges
- Shooters who want a clearer optic sight picture without room taken up by the larger sized FFP reticle
Rifle Scope Magnification
The quantity of magnification a scope offers 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.
Single Power Lens Glass Info
A single power rifle scope comes with a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not change since it is a set power scope.
Variable Power Lens Rifle Glass Facts
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom degree in a format such as 2-10×32. These numbers suggest the magnification of the scope can be set between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power modification is accomplished by employing the power ring component of the scope near the back of the scope by the eye bell piece.
Glass Power Level and Range Correlation
Here are some suggested scope power settings and the ranges where they may be effectively used. Bear in mind that higher magnification scopes will not be as efficient as lower magnification level scopes since excessive zoom can be a detractor. The same idea applies to extended ranges where the shooter needs to have adequate power to see where to properly aim the rifle at the target.
Info on Lens Covering
All present day rifle scope lenses are covered. Lens covering is an essential element of a rifle when considering high end rifle optics and scope systems.
Info on Lens Coatings – HD Versus ED
Some optic suppliers additionally use “HD” or high-def lense finishes which make the most of various procedures, aspects, polarizations, and chemical applications to draw out various color ranges and viewable definition through the lens. This HD finishing is normally used with more costly, high density glass which lowers light’s potential to refract through the lens glass. Some scope vendors use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration can be obvious around objects with hard edges and shapes as light hits the item from certain angles.
Single Rifle Glass Lens Coating Versus Multi-Coating
Various optic lenses can likewise have different coatings applied to them. All lenses normally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while lowering glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope maker and the amount you paid for it. Both the make and cost are indicators of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” covered. This means the lens has had multiple treatments applied to the surfaces of the glass. If a lens receives several treatments, it can show that a company is taking several steps to fight different environmental elements like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This additionally does not always mean the multi-coated lens is much better than a single coated lens. Being “much better” is dependent on the manufacturer’s lens treatment innovation and the quality of products used in constructing the rifle glass.
Hydrophobic Optic Lens Covering
Water on a scope’s lens doesn’t assist with retaining a clear sight picture through a scope at all. Lots of top of the line or high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the exterior of the Steiner glass lens so the water particles can not bind to it or create surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Options for Installing Rifle Scopes on Firearms
Installing approaches for scopes come in a few choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also typically can be found in quick release versions which use manual levers which permit rifle operators to quickly install and dismount the glass.
Hex Key Scope Ring Mounts
Standard, clamp type mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use a pair of separate rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are created for far away precision shooting. This type of scope mount is effective for rifle systems which are in need of a long lasting, hard use mount which will not move despite how much the scope is moved about or abuse the rifle takes. These are the design of mounts you want for a faithful optics setup on a reach out and touch someone scouting or competition rifle which will almost never need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to keep the hex screws from backing out after they are mounted safely in place. An example of these mounting rings are the 30mm type from Vortex Optics. The set usually costs around $200 USD
Rifle Scope Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be switched out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining precision. These types of mounts are useful and handy for rifles which are transferred between vehicles a lot, to take off the optic from the rifle for protection, or for scopes which are utilized in between multiple rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It normally costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle optic can destroy a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope’s tube. Many scopes protect against moisture from getting in the optical tube with a system of sealing O-rings which are waterproof. Usually, these scopes can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of wetness prevention for standard use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on your motorboat and are concerned about the scope still performing if it falls overboard and you can still retrieve the rifle.
What to Know About Rifle Glass Tube Gas Purging
Another part of preventing the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the optic is less influenced by condition shifts and pressure variations from the outside environment which might potentially permit water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
