Rifle Optic Facts
Rifle scopes enable you to precisely align a rifle at various targets by lining up your eye with the target at range. They do this through zoom by making use of a series of lenses inside the scope. The scope’s positioning can be adapted for the consideration of different natural aspects like wind speed 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 seeing using the optic as you line up the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes and optics have about eleven parts which are found inside and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, modification turrets, objective focus rings, and other elements. See all eleven parts of optics.
About Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the perfect type of rifle optic depends on what type of shooting you plan on doing.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who know their target “hold over” and also “lead” correlations for their rifles
- Shooters who do not mind the reticle is bigger and takes up more visual sight area than a SFP reticle
About Second Focal Plane Glass
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 measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance styles of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots take place within much shorter ranges and spaces
- Shooters who prefer a clearer optic sight picture with less area used up by the enlarged FFP reticle
Rifle Optic Zoom
The amount of magnification a scope provides is figured out 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.
Single Power Lens Scope Info
A single power rifle optic or scope will have a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not adjust because it is fixed.
Adjustable Power Lens Glass
Variable power rifle scopes can be changed between magnification increments. It will list the zoom degree in a configuration like 2-10×32. These numbers indicate the zoom of the scope could be adjusted in between 2x and 10x power. This also utilizes the power levels in-between 2 and 10. The power modification is accomplished by working with the power ring component of the scope near the rear of the scope by the eye bell.
The Power and Range of Scopes
Here are some advised scope power levels and the distances where they can be successfully used. Highly magnified optics will not be as efficient as lower magnification glass considering that too much magnification can be a bad thing. The exact same idea applies to longer distances where the shooter needs sufficient power to see precisely where to best aim the rifle at the target.
Glass Lens Covering
All contemporary rifle scope lenses are covered in special coatings. There are various types and qualities of glass lens finishes. When researching luxury rifle scope setups, Lens finishing can be a very important element of defining the capability of the rifle. The glass lenses are among the most key pieces of the optic given that they are what your eye looks through while sighting a rifle in on the point of impact. The finishing on the lenses shields the lens surface area and improves anti glare capabilities from excess daylight and color discernibility.
HD Versus ED Lenses
Some scope manufacturers likewise use “HD” or high-definition lens finishings which use different techniques, chemicals, polarizations, and aspects to draw out various colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Coating Versus Multi-Coating
Various scope lenses can even have various finishings applied to them. All lenses generally have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. This is since the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It must have a finishing placed on it so that it will be optimally functional in many types of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and the amount you spent for it. The scope’s maker and cost are indicators 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 maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Anti-water Lens Finishes
Water on a lens does not help with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic anti-water finish.
Optic Installation Alternatives
Installing solutions for scopes can be found in a couple of choices. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also generally are made in quick release variations which use throw levers which permit rifle operators to quickly mount and dismount the glass.
Hex Key Glass Ring Mounting Solutions
Standard, clamp-on type mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mount rails on the tops of rifles. These styles of scope mounts use double individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are designed for far away accuracy shooting. This form of scope mount is effective for rifles which are in need of a long lasting, unfailing mount which will not change despite just how much the scope is moved about or abuse the rifle takes. These are the style of mounts you should have for a specialized scope system on a long distance hunting or hard target interdiction rifle which will rarely need to be modified 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 installed securely in place. An example of these rings are the 30mm style made by Vortex Optics. The set typically costs around $200 USD
Rifle Glass Mounts with Quick-Release Cantilever Rings
These types 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. If they all use a comparable style mount, several scopes can often be switched out. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping accuracy. These types of mounts are useful and convenient for shooting platforms which are moved around a lot, to remove the scope glass from the rifle for protection, or for aiming systems which are utilized in between several rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle scope can mess up a day of shooting and your pricey optic by bringing about fogging and producing residue inside of the scope tube. Many scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
About Rifle Scope Tube Gas Purging
Another component of avoiding the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the glass is less affected by climate changes and pressure differences from the outdoor environment which might potentially permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
