Scope Facts
Rifle scopes permit you to precisely align a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through magnification by making use of a set of lenses inside the scope. The scope’s positioning can be adjusted for consideration of separate environmental factors like wind and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the target. Many modern-day rifle optics have about eleven parts which are arranged internally and outside of the scope. These parts consist of the rifle scope’s body, lenses, elevation dials, focus rings, and other elements. See all eleven parts of a rifle scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane a scope has identifies where the reticle or crosshair lies in regard to the scopes magnification. It actually suggests the reticle is located behind or in front of the magnifying lens of the optic. Selecting the most suitable kind of rifle glass is dependent on what form of shooting or hunting you anticipate doing.
About First Focal Plane Optics
First focal plane scopes (FFP) feature the reticle before the magnifying lens. This induces the reticle to increase in size based upon the level of zoom being used. The outcome is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are small
- Experienced shooters who recognize their target “hold over” and also “lead” relationships for their firearm
- Shooters who don’t mind the reticle is bigger and uses up more visual sight area than a SFP reticle
Second Focal Plane Scope Details
Second focal plane scopes (SFP) include the reticle behind the magnification 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 measurement.
- Long distance types of shooting where shooters have more time to make ballistic computations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who would like a clearer optic picture without area used up by the enlarged FFP reticle
Zoom for Rifle Optics
The amount of magnification a scope provides is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Fixed Power Lens Glass
A single power rifle optic 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 fluctuate given that it is a fixed power optic.
About Variable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification increments. It will note the zoom amount in a configuration such as 2-10×32. These numbers mean the magnification of the scope can be adjusted between 2x and 10x power. This additionally utilizes the power levels in-between 2 and 10. The power adaptation is achieved by working with the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range
Here are some recommended scope power settings and the ranges where they may be successfully used. High power glass will not be as useful as lower magnification level scopes since too much zoom can be a bad thing. The same relates to extended distances where the shooter needs sufficient power to see exactly where to best aim the rifle at the target.
Details on Lens Coverings
All contemporary rifle optic and scope lenses are coated. There are different types and qualities of glass lens coverings. When thinking about high end rifle scope setups, Lens covering can be an essential component of a rifle. The lenses are one of the most important parts of the glass considering they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens surface area as well as assists with anti glare from excess sunlight and color perception.
HD Versus ED Lens Coatings
Some scope makers likewise use “HD” or high-definition lens coatings which use various processes, aspects, polarizations, and chemicals to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Scope Lens Finishing Versus Multi-Coating
Various optic lenses can even have different finishings applied to them. All lenses normally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It must have a finishing placed on it so that the lens will be optimally usable in numerous kinds of environments, degrees of light (full VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” covered. This indicates the lens has had several treatments applied to them. If a lens gets several treatments, it can prove that a manufacturer is taking several actions to fight different natural factors like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This also does not always indicate the multi-coated lens is much better than a single covered lens. Being “better” depends on the producer’s lens treatment solutions and the quality of components used in constructing the rifle glass.
Hydrophobic Finish for Rifle Optics
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Numerous top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic finish.
Choices for Mounting Rifle Glass on Long Guns
Mounting solutions for scopes are available in a couple of options. There are the basic scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also normally come in quick release variations which use throw levers which permit rifle operators to quickly install and dismount the scope.
Hex Key Rifle Optic Rings
Normal, 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 a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long distance precision shooting. This type of scope mount is wonderful for rifles which require a resilient, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope and connect it to a different rifle. Several scopes can also be switched out if they all use a similar style mount. These types of mounts are convenient for long guns which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between several rifles or are situationally focused.
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle scope can mess up a day on the range and your highly-priced optic by resulting in fogging and developing residue inside of the scope’s tube. A lot of scopes protect against humidity from getting in the optical tube with a series of sealing O-rings which are water resistant. Generally, these scopes can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture content avoidance for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle on boats and are worried about the scope still working if it is submerged in water and you can still recover the firearm.
About Rifle Glass Tube Gas Purging
Another component of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is already taken up by the gas, the optic is less affected by climate alterations and pressure variations from the external environment which might potentially permit water vapor to seep 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.
