Optic Facts
Rifle scopes permit you to specifically align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnification by employing a set of lenses within the scope. The scope’s alignment can be adapted for the consideration of varied natural things like wind and elevation to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended target. Many modern-day rifle scopes have about eleven parts which are located inside and outside of the optic. These scope parts include the rifle scope’s body, lenses, elevation turrets or dials, focus rings, and other elements. Learn about the eleven parts of scopes.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the optimal type of rifle glass is based around what type of shooting you plan on doing.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are minimal
- Experienced shooters who understand their aim point “hold over” and “lead” correlations for their long guns
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle to the rear of the zoom 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 reticle measurement.
- Far away styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots occur within shorter distances and ranges
- Shooters who prefer a clearer optic picture with less area used up by the larger sized FFP reticle
About Rifle Optic Zoom
The amount of zoom a scope offers 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.
Fixed Single Power Lens Rifle Scope Info
A single power rifle scope or optic uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not change given that it is a set power scope.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be changed between magnification levels. These types of scopes will list the magnification degree in a configuration like 2-10×32. These numbers imply the zoom of the scope can be changed between 2x and 10x power. This additionally involves the power levels in-between 2 and 10. The power adjustment is achieved utilizing the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Rifle Scopes
Here are some recommended scope powers and the distances where they can be efficiently used. Consider that high magnification scopes will not be as practical as lower powered scopes because too much zoom can be a negative thing in certain situations. The same relates to longer distances where the shooter needs to have sufficient power to see where to properly aim the rifle at the target.
About Glass Lens Coverings
All modern-day rifle scope and optic lenses are covered in special coatings. There are various types and qualities of lens coatings. When shopping for high end rifle scope systems, Lens finish can be a vital aspect of a rifle. The lenses are among the most vital pieces of the glass considering they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses protects the lens surface as well as improves anti glare from excess sunrays and color profiles.
HD Versus ED Lens Coatings
Some scope manufacturers also use “HD” or high-definition lens coverings which use various techniques, components, chemicals, and polarizations to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Rifle Scope Lens Coating Versus Multi-Coating
Different scope lenses can even have various coatings applied to them. All lenses usually have at least some kind of treatment or coating applied to them prior to 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 finely tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in lots of types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing 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 maker and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are layered or “multi” coated. This implies the lens has numerous treatments applied to the surfaces. If a lens gets numerous treatments, it can prove that a producer is taking numerous steps to fight various natural elements like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This also does not necessarily indicate the multi-coated lens is better than a single layered lens. Being “much better” hinges on the producer’s lens treatment solutions and the quality of materials used in creating the rifle glass.
About Hydrophobic Covering
Water on an optical lens does not assist with preserving a clear sight picture through an optic whatsoever. Numerous top of the line and high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the surface of the Steiner glass lens so the H2O particles can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Scope Installing Options
Mounting options for scopes come in a couple of options. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also typically can be found in quick release variations which use throw levers which allow rifle operators to quickly install and remove the scope.
Hex Key Rifle Glass Rings
Basic, clamp-on type mounting scope rings use hex head screws to install to the flattop style Picatinny scope mount rails on rifles. These forms of scope mounts use double independent rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are created for far away accuracy shooting. This form of scope mount is great for rifles which need a resilient, rock solid mount which will not change regardless of just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you really want to have for a dedicated optics setup on a long distance hunting or competition long gun that will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the screws to prevent the hex screws from wiggling out after they are installed tightly in position. An example of these mounting rings are the 30mm style made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. If they all use a similar style mount, multiple scopes can also be swapped out in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining the original sighting settings. These kinds of mounts are useful and beneficial for rifles which are shipped a lot, to remove the glass from the rifle for protection, or for scopes which are chosen for use in between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Info Around Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your costly optic by causing fogging and producing residue inside of the scope tube. Most scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another element of preventing the accumulation of moisture inside of the rifle scope 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 impacted by condition alterations and pressure distinctions from the external environment which could possibly enable water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
