Facts About Rifle Scopes
Rifle scopes enable 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 series of lenses within the scope. The scope’s alignment can be adapted for consideration of numerous natural 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 on the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes and optics have about 11 parts which are located inside and outside of the scope body. These parts include the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other components. See all eleven parts of a scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane a scope has identifies where the reticle or crosshair lies relative to the optic’s magnification. It actually indicates the reticle is located behind or ahead of the magnification lens of the optic. Choosing the most desired sort of rifle optic is based on what kind of shooting or hunting you intend on doing.
First Focal Plane Optic Details
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are small
- Experienced shooters who know their target “hold over” plus “lead” relationships for their weapon
- Shooters who do not mind the reticle is bigger and takes up more visual sight space than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle behind the magnifying lens. This triggers the reticle to stay at the exact same dimensions in connection with the volume of magnification being used. The result is that the reticle dimensions adjust based upon the zoom chosen to shoot over lengthier distances considering that the reticle measurements present different increments which differ with the zoom level. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These sorts of scopes are beneficial for:
- Long distance kinds of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots happen within shorter proximities and ranges
- Shooters who select a clearer optic picture without area used up by the larger sized FFP reticle
Details on Glass Zoom
The amount of zoom a scope provides is determined 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 Power Lens Rifle Glass
A single power rifle scope comes with a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not change because it is set from the factory.
About Variable Power Lens Optics
Variable power rifle scopes can be changed between magnification increments. It will list the zoom level in a format such as 2-10×32. These numbers mean the magnification of the scope could be adjusted between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power manipulation is achieved utilizing the power ring part of the scope near the back of the scope by the eye bell piece.
Scope Power Level and Range Correlation
Here are some advised scope power levels and the ranges where they can be successfully used. Remember that high power optics will not be as practical as lower powered scopes because increased zoom can be a negative thing in certain situations. The same goes for extended ranges where the shooter needs sufficient power to see exactly where to best aim the rifle.
Lens Finish for Optics
All state-of-the-art rifle glass lenses are covered. Lens covering can be a crucial element of a shooting platform when purchasing high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope makers likewise use “HD” or high-definition lens finishes which use different techniques, chemicals, polarizations, and aspects to draw out separate 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 Coating Versus Multi-Coating for Rifle Optics
Different scope lenses can also have different coatings applied to them. All lenses typically have at least some kind of treatment or coating applied to them before being used in a rifle scope or optic. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally usable in numerous types of environments, degrees of light (full VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope company and how much money you spent on it. Both are indicators of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are layered or “multi” covered. This indicates the lens has had several treatments applied to the surfaces. If a lens gets numerous treatments, it can show that a company is taking numerous actions to combat different environmental elements like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic covering. This additionally doesn’t always imply the multi-coated lens will perform better than a single covered lens. Being “better” depends on the producer’s lens treatment techniques and the quality of glass used in building the rifle scope.
Hydrophobic Lens Covering
Water on a lens does not help with preserving a clear sight picture through a scope at all. Many top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic coating.
Options for Installing Scopes on Long Guns
Installing approaches for scopes are available in a few choices. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also generally can be found in quick release variations which use throw levers which permit rifle operators to quickly install and remove the scope.
Hex Key Glass Rings
Basic, clamp design mounting optic rings use hex head screws to position to the flattop style Picatinny scope mount rails on rifles. These varieties of scope mounts use a pair of individual rings to support the scope, and are normally constructed from 7075 T6 billet aluminum which are made for long distance accuracy shooting. This kind of scope mount is exceptional for rifle systems which need a resilient, rock solid mount which will not change despite how much the scope is moved or jarring the rifle takes. These are the style of mounts you should have for a faithful scope setup on a far away scouting or tournament long gun that will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount screws to protect against the hex screw threads from wiggling out after they are mounted tightly in place. An example of these rings are the 30mm type from the Vortex Optics company. The set generally costs around $200 USD
Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and attach it to a different rifle. Multiple scopes can even be switched out if they all use a similar design mount. These types of mounts come in handy for rifle platforms which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between numerous rifles.
Info on Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your expensive optic by causing fogging and creating residue inside of the scope tube. The majority of scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Rifle Optic Gas Purging
Another component of preventing the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the glass is less influenced by temp 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.
