Info About Scopes
Rifle scopes allow you to precisely align a rifle at different targets by aligning your eye with the target over a distance. They do this through magnification by employing a set of lenses inside the scope. The scope’s positioning can be adapted for consideration of varied natural factors like wind speed and elevation increases to account for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Most modern rifle scopes have about 11 parts which are found internally and outside of the scope. These scope parts consist of the rifle scope’s body, lenses, windage and elevation dials or turrets, focus rings, and other components. Learn about the eleven parts of scopes.
The Types 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 establishes where the reticle or crosshair lies in relation to the scopes magnifying adjustments. It simply implies the reticle is located behind or ahead of the magnification lens of the scope. Choosing the very best kind of rifle optic depends upon what style of shooting or hunting you intend on doing.
About First Focal Plane Scopes
First focal plane optics (FFP) come with the reticle before the zoom lens. This induces the reticle to increase in size based upon the extent of magnification being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified distance. For example, one tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at one hundred yards using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who have an idea for their target “hold over” and also “lead” relationships for their rifles
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle to the rear of the magnification 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 measurement.
- Far away forms of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots take place within much shorter distances and ranges
- Shooters who prefer a clearer optic sight picture with less area taken up by the larger sized FFP reticle
Rifle Scope Zoom
The quantity 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 Power Lens Glass
A single power rifle optic or scope will have a zoom 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 adjust considering that it is a fixed power optic.
About Variable Power Lens Rifle Scopes
Variable power rifle scopes can be modified between magnified levels. The power change is handled by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Rifle Glass
Here are some recommended scope power levels and the ranges where they may be successfully used. High power scopes will not be as beneficial as lower powered optics considering too much magnification can be a negative aspect depending on your shooting distance. The same idea relates to extended distances where the shooter needs to have adequate power to see exactly where to properly aim the rifle.
Rifle Scope Lens Covering
All modern-day rifle scope lenses are coated. There are different types and qualities of coatings. When looking at luxury rifle optics and scope systems, Lens finish can be a crucial element of defining the rifle’s capability. The lenses are one of the most critical components of the glass since they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses shields the lens surface as well as assists with anti glare capabilities from excess direct sunlight and color presence.
HD Versus ED Lens Coatings
Some rifle glass producers will also use “HD” or high-def lens coverings which take advantage of various processes, chemicals, elements, and polarizations to extract a wide range of colors and viewable definition through lenses. This high-def coating is frequently used with higher density lens glass which brings down light’s capability to refract by means of the lens glass. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be obvious over objects with defined outlines as light hits the item from specific angles.
About Single Finish Versus Multi-Coating
Different optic lenses can even have different coverings 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 becomes part of the finely tuned optic. It must have a coating put on it so that it will be optimally usable in lots of types of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope producers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This suggests the lens has numerous treatments applied to them. If a lens gets several treatments, it can indicate that a producer is taking several actions to combat various environmental elements like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This also does not necessarily mean the multi-coated lens will perform better than a single layered lens. Being “much better” depends upon the producer’s lens treatment solutions and the quality of components used in creating the rifle glass.
Anti-water Coating for Rifle Glass
Water on an optic’s lens does not help with keeping a clear sight picture through a scope at all. Lots of top of the line or high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the exterior of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The result is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Scopes on Long Guns
Mounting solutions for scopes are available in a few options. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also typically are made in quick release versions which use toss levers which permit rifle operators to quickly install and dismount the optics.
Hex Key Rifle Optic Rings
Basic, clamp-on design mounting optic rings use hex head screws to install to the flattop style Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use double independent rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope mount is good for rifle systems which require a durable, hard use mount which will not change despite just how much the scope is moved or abuse the rifle takes. These are the style of mounts you want for a faithful optics system on a far away hunting or interdiction rifle which will seldom need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to stop the hex screw threads from backing out after they are installed safely in place. An example of these rings are the 30mm style made by the Vortex Optics brand. The set generally costs around $200 USD
Quick-Release Cantilever Glass Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle. If they all use a similar design mount, multiple scopes can also be switched in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping the original sighting settings. These kinds of mounts are useful and beneficial for rifles which are transferred between vehicles a lot, to remove the glass from the rifle for protection, or for sight systems which are used between several rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle scope can destroy a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. Most scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Optic 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. Considering that this area is currently occupied by the gas, the optic is less influenced by temp alterations and pressure differences from the outside environment which might potentially enable water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
