Optic Facts
Rifle scopes enable you to precisely align a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through magnifying the target by utilizing a series of lenses inside the scope. The scope’s alignment can be dialed in to account for different natural factors like wind and elevation to account for bullet drop.
The scope’s function is to understand precisely where the bullet will land based on the sight picture you are seeing with the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern rifle scopes and optics have about 11 parts which are found internally and externally on the scope body. These scope parts include the rifle scope’s body, lenses, elevation dials, objective focus rings, and other parts. See all eleven parts of a rifle scope.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has identifies where the reticle or crosshair lies in connection with the scopes magnification. It actually implies the reticle is located behind or before the magnification lens of the scope. Selecting the most suitable style of rifle optic depends upon what variety of hunting or shooting you plan on undertaking.
First Focal Plane Scope Facts
First focal plane glass (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based on the amount of zoom being used. The result is that the reticle measurements are the same at the magnified range as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are minimal
- Experienced shooters who know their target “hold over” as well as “lead” correlations for their weapon
- Shooters who don’t mind the reticle is enlarged and requires more visual sight space than a SFP reticle
Second Focal Plane Optic Info
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick.
- Long distance forms of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots happen within shorter spaces and ranges
- Shooters who prefer a clearer optic sight picture without room taken up by the larger size FFP reticle
Rifle Optic Magnification
The measure of scope magnification you need on your scope depends upon the style of shooting you want to do. Practically every style of rifle glass supplies some level of zoom. The volume of magnification a scope offers is established by the diameter, density, and curves of the lenses within the rifle scope. The zoom of the scope is the “power” of the opic. This implies what the shooter is aiming at through the scope is magnified times the power factor of what can generally be seen by human eyes.
About Fixed Power Lens Optics
A single power rifle scope and optic will have a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not fluctuate because it is fixed.
Adjustable Power Lens Glass
Variable power rifle scopes can be adjusted between magnification power levels. These types of scopes will note the magnification amount in a configuration like 2-10×32. These numbers imply the magnification of the scope can be set between 2x and 10x power. This always incorporates the power levels in-between 2 and 10. The power adjustment is achieved by operating the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some suggested scope powers and the ranges where they can be successfully used. Remember that higher power scopes and optics will not be as efficient as lower powered scopes since increased zoom can be a negative thing in certain situations. The exact same concept applies to longer distances where the shooter needs enough power to see precisely where to properly aim the rifle at the target.
Scope Lens Covering
All current rifle scope and optic lenses are covered. Lens covering is a crucial aspect of a rifle’s setup when buying high end rifle optics and scope equipment.
HD Versus ED Rifle Optic Lens Coatings
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use different techniques, polarizations, components, and chemicals to draw out a wide range of colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Glass Lens Single Covering Versus Multi-Coating
Various scope lenses can also have different coatings applied to them. All lenses usually have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be optimally functional in lots of types of environments, degrees of light (full VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are layered or “multi” covered. This indicates the lens has several treatments applied to the surfaces of the glass. If a lens gets several treatments, it can establish that a company is taking numerous steps to combat various natural aspects like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This also does not always suggest the multi-coated lens is better than a single coated lens. Being “much better” depends upon the maker’s lens treatment innovation and the quality of components used in constructing the rifle scope.
Anti-water Rifle Optic Lens Finish
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic anti-water finishing.
Rifle Optic Installation Options
Mounting approaches for scopes come in a couple of options. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also normally come in quick release variations which use toss levers which allow rifle shooters to rapidly install and remove the scope.
Scope Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long range precision shooting. This type of scope install is wonderful for rifles which require a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle. If they all use a comparable style mount, several scopes can also be switched in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving accuracy. These types of mounts come in practical for rifles which are carried a lot, to remove the scope from the rifle for protection, or for sight systems which are used between a number of rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can wreck a day on the range and your highly-priced optic by resulting in fogging and producing residue inside of the scope tube. Most optics prevent moisture from entering the optical tube with a series of sealing O-rings which are waterproof. Typically, these scopes can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient humidity prevention for standard use rifles, unless you intend on taking your rifle aboard a watercraft and are concerned about the scope still functioning if it goes overboard and you can still retrieve the firearm.
Gas Purged Rifle Glass Tubes
Another element of avoiding the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is already taken up by the gas, the glass is less impacted by temperature alterations and pressure differences from the external environment which might possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
