Rifle scopes permit you to exactly align a rifle at various targets by lining up your eye with the target over a range. They do this through magnifying the target using a set of lenses inside the scope. The scope’s positioning can be adapted for consideration of different ecological things like wind speed and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle scopes have around 11 parts which are found inside and on the exterior of the optic. These optic pieces include the rifle scope’s body, lenses, modification dials, objective focus rings, and other components. See all eleven parts of a rifle scope.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the optimal type of rifle glass depends on what type of shooting you plan to do.
First Focal Plane Glass
First focal plane scopes (FFP) feature the reticle in front of the zoom lens. This induces the reticle to increase in size based upon the level of magnification being used. The result is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. For example, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the exact same tick at one hundred yards using 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are marginal
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” ratios for their rifles
- Shooters who don’t mind the reticle is enlarged and occupies more visual sight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Far away forms of shooting where shooters have additional time to make ballistic computations
- Shooting where most of the shots happen within much shorter spaces and ranges
- Shooters who like a clearer optic picture with less room taken up by the larger sized FFP reticle
Rifle Glass Magnification
The amount of zoom a scope offers is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
About Fixed Single Power Lens Rifle Glass
A single power rifle optic or scope comes with a magnification number designator like 4×32. This means 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 set from the factory.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification levels. These types of scopes will note the magnification amount in a configuration such as 2-10×32. These numbers indicate the zoom of the scope could be changed between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power adaptation is achieved by working with the power ring component of the scope near the back of the scope by the eye bell piece.
The Power and Range Correlation of Rifle Optics
Here are some recommended scope power settings and the ranges where they may be efficiently used. Consider that high magnification glass will not be as efficient as lower magnification level scope and optics because excessive magnification can be a negative thing in certain situations. The very same idea applies to extended distances where the shooter needs enough power to see where to best aim the rifle.
Details on Lens Coating
All modern rifle optic and scope lenses are layered. There are different types and qualities of glass finishes. When looking at luxury rifle optical systems, Lens finishing can be an essential aspect of defining the capability of the rifle. The glass lenses are among the most essential components of the scope considering that they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses protects the lens surface as well as improves anti glare capabilities from excess direct sunlight and color presence.
About Lens Coatings – HD Versus ED
Some scope brands also use “HD” or high-definition lens finishes which use various methods, polarizations, aspects, and chemicals to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Rifle Optic Lens Single Finish Versus Multi-Coating
Different optic lenses can also have various coverings applied to them. All lenses generally have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It needs to have a finishing placed on it so that it will be optimally functional in lots of kinds of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is normally 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 coated lens depends on the scope producer and how much money you paid for it. Both are signs of the lens quality.
Some scope makers likewise make it a point to specify if their optic lenses are coated or “multi” coated. This means the lens has had numerous treatments applied to the surfaces. If a lens gets numerous treatments, it can indicate that a company is taking numerous steps to combat different environmental elements like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This additionally does not necessarily suggest the multi-coated lens will perform much better than a single coated lens. Being “better” depends upon the maker’s lens treatment solutions and the quality of products used in building the rifle optic.
Info on Hydrophobic Coating
Water on an optical lens does not assist with maintaining a clear sight picture through a scope at all. Lots of top of the line or premium scope makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It deals with the surface 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 Mounting Glass on Firearms
Mounting approaches for scopes come in a few options. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also typically are made in quick release variations which use throw levers which permit rifle operators to rapidly mount and remove the scope.
Hex Key Rifle Scope Rings
Standard, clamp design mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use two detached rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for far away precision shooting. This type of scope mount is good for rifles which need a long lasting, rock solid mount which will not change despite how much the scope is moved about or abuse the rifle takes. These are the design of mounts you want for a faithful scope setup on a long distance scouting or interdiction long gun that will pretty much never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on screws to prevent the hex screws from wiggling out after they are installed firmly in position. An example of these rings are the 30mm type made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible design mount. These types of mounts are handy for rifles which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used between numerous rifles.
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by triggering 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.
What to Know About Rifle Glass Tube Gas Purging
Another element of preventing the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the glass is less affected by temperature level changes and pressure variations from the external environment which might potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
