Rifle Scope Facts
Rifle scopes allow you to exactly aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification by employing a series of lenses within the scope. The scope’s alignment can be dialed in to account for numerous natural considerations like wind and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing through the optic as you line up the scope’s crosshair or reticle with the intended target. Most contemporary rifle optics have around eleven parts which are located within and externally on the optic. These parts include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other components. See all eleven parts of optics.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane an optic has decides where the reticle or crosshair is located in connection with the scopes magnification. It literally means the reticle is located behind or ahead of the magnifying lens of the optic. Looking for the most reliable type of rifle glass is based on what form of hunting or shooting you plan on undertaking.
About First Focal Plane Optics
First focal plane optics (FFP) include the reticle in front of the magnification lens. This causes the reticle to increase in size based upon the amount of magnification being used. The outcome is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. As an example, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the corresponding tick at one hundred yards using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting situations where computations are very little
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” relationships for their weapon
- Shooters who do not mind the reticle is bigger and occupies more visual sight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Long distance types of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots happen within much shorter ranges and proximities
- Shooters who would like a clearer optic picture without area used up by the enlarged FFP reticle
Zoom for Optics
The level of scope magnification you need on your scope depends upon the style of shooting you intend to do. Practically every kind of rifle scope offers some amount of magnification. The level of magnification a scope delivers is established by the size, thickness, and curvatures of the lens glass within the rifle scope. The magnification level of the optic is the “power” of the glass. This implies what the shooter is aiming at through the scope is magnified times the power factor of what can typically be seen by human eyes.
About Fixed Single Power Lens Glass
A single power rifle scope uses a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not change since it is a fixed power optic.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be modified between magnified settings. The power adjustment is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range
Here are some recommended scope power levels and the distances where they may be efficiently used. Always remember that high power optics and scopes will not be as practical as lower powered scopes due to the fact that increased magnification can be a detractor. The same idea relates to longer ranges where the shooter needs to have increased power to see where to best aim the rifle at the target.
Lens Finish for Scopes
All contemporary rifle scope lenses are layered. There are different types and qualities of glass lens finishes. When thinking about high end rifle optical units, Lens covering can be a significant aspect of defining the capability of the rifle. The lenses are one of the most crucial components of the optic since they are what your eye sees through while sighting a rifle in on the point of impact. The coating on the lenses offers protection to the lens surface area and even improves anti glare capabilities from refracted natural light and color recognition.
Info on Rifle Scope Lens Coatings – HD Versus ED
Some optic suppliers additionally use “HD” or high-def lense coverings that take advantage of different processes, chemicals, components, and polarizations to extract numerous colors and viewable definition through the lens. This high-definition covering is typically used with more costly, high density lens glass which brings down light’s capability to refract through the lens glass. Some scope makers use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration is often obvious over things with defined outlines as light hits the object from specific angles.
Single Finishing Versus Multi-Coating for Rifle Glass
Different scope lenses can also have different coverings applied to them. All lenses normally have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic assembly. This is since the lens isn’t just a raw piece of glass. It is part of the finely tuned optic. It must have a finish placed on it so that the lens will be efficiently functional in lots of types of environments, degrees of light (full light VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. 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 optic. The quality of a single layered lens depends upon the scope company and just how much you spent on it. The scope’s maker and cost are signs of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are layered or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Hydrophobic Lens Finishes
Water on an optical lens does not help with keeping a clear sight picture through an optic whatsoever. Lots of top of the line or high-end optic producers 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 deals with the exterior surfaces of the Steiner scope lens so the water particles can not bind to it or produce surface tension. The result is that the water beads move off of the scope to maintain a clear, water free sight picture.
Choices for Mounting Rifle Optics on Firearms
Mounting options for scopes are available in a couple of options. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also typically are made in quick release versions which use manual levers which permit rifle shooters to quickly install and remove the scope.
Hex Key Rifle Scope Ring Mounting Solutions
Standard, clamp design mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use two detached rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are created for long distance accuracy shooting. This form of scope mount is great for rifles which require a durable, hard use mount which will not change regardless of just how much the scope is moved about or jarring the rifle takes. These are the design of mounts you should get for a dedicated scope system on a reach out and touch someone scouting or tournament long gun that will almost never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount screws to protect against the hex screws from backing out after they are mounted tightly in position. An example of these mounting rings are the 30mm style from the Vortex Optics company. The set normally costs around $200 USD
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle. If they all use a similar design mount, a number of scopes can often be switched on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping the original sighting settings. These kinds of mounts are useful and beneficial for shooting platforms which are moved around a lot, to remove the scope glass from the rifle for protection, or for optics which are employed between several rifles. An example of this mount style is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Details on Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can mess up a day of shooting and your pricey optic by bringing about fogging and developing residue inside of the scope tube. A lot of scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Glass Tubes
Another element of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the scope is less impacted by temperature level alterations and pressure distinctions from the outdoor environment which may potentially permit water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
