Rifle scopes allow you to specifically align a rifle at different targets by lining up your eye with the target over a distance. They do this through magnifying the target by employing a set of lenses within the scope. The scope’s alignment can be dialed in for consideration of separate natural factors like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based on the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle scopes and optics have around 11 parts which are arranged internally and externally on the scope body. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of rifle scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the finest type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Scopes
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 magnified range as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are small
- Experienced shooters who understand their aim point “hold over” plus “lead” correlations for their rifles
- Shooters who do not mind the reticle is bigger and requires more visual sight space than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle behind the magnifying lens. This causes the reticle to remain at the very same size in relation to the quantity of magnification being used. The result is that the reticle measurements adapt based upon the magnification used to shoot over greater distances because the reticle markings represent various increments which vary with the zoom level. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These particular sorts of optics work for:
- Far away types of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots take place within much shorter spaces and ranges
- Shooters who would like a clearer optic sight picture without area used up by the larger size FFP reticle
Rifle Optic Zoom
The extent of scope zoom you need depends on the type of shooting you plan to do. Pretty much every type of rifle scope offers some level of magnification. The volume of magnification a scope supplies is determined by the dimension, thickness, and curves of the lenses inside of the rifle scope. The zoom of the optic is the “power” of the scope. This denotes what the shooter is observing through the scope is amplified times the power aspect of what can normally be seen by human eyes.
Info About Fixed Single Power Lens Rifle Glass
A single power rifle scope or optic will have a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not adjust given that it is a fixed power scope.
About Adjustable Power Lens Rifle Glass
Variable power rifle scopes use variable power levels. The power modification is performed by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Rifle Scopes
Here are some recommended scope powers and the distances where they could be effectively used. Consider that higher magnification optics and scopes will not be as practical as lower powered scope and optics due to the fact that excessive magnification can be a bad thing. The same concept applies to longer ranges where the shooter needs adequate power to see exactly where to properly aim the rifle.
Info on Lens Coating
All contemporary rifle optic lenses are coated. There are various types and qualities of lens coatings. When considering high end rifle targeting devices, Lens finish can be a critical element of defining the rifle’s capability. The lenses are among the most vital parts of the optic as they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses safeguards the lens surface and helps with anti glare from refracted sunshine and color presence.
HD Versus ED Lenses
Some scope manufacturers will also use “HD” or high-definition glass finishes which use various procedures, rare earth compounds, aspects, and polarizations to draw out separate color ranges and viewable definition through lenses. This high-definition finishing is often used with more costly, high density lens glass which brings down light’s potential to refract through the lens glass. Some scope suppliers use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration is often visible over objects with defined shapes as light hits the object from specific angles.
Scope Lens Single Covering Versus Multi-Coating
Various optic lenses can likewise have various finishes applied to them. All lenses usually have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope company and just how much you paid for it. Both the manufacturer and amount are signs of the lens quality.
Some scope manufacturers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This indicates the lens has several treatments applied to them. If a lens gets several treatments, it can indicate that a manufacturer is taking numerous actions to combat different natural factors like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This also doesn’t always imply the multi-coated lens is much better than a single coated lens. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of glass used in creating the rifle scope.
Anti-water Finishing for Rifle Scopes
Water on a lens does not support keeping a clear sight picture through an optic whatsoever. Many 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 fine example of this type of treatment. It deals with the exterior of the Steiner scope lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Rifle Optic Installation Alternatives
Installing approaches for scopes are available in a few options. There are the basic scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically are made in quick release versions which use manual levers which enable rifle operators to quickly mount and dismount the optics.
Glass Mounting Solutions with Hex Key Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope mount is perfect for rifles which need a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Glass Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be switched out if they all use a similar designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving the original sighting settings. These types of mounts are useful and beneficial for shooting platforms which are hauled around a lot, to remove the scope glass from the rifle for protection, or for optics which are used in between a number of rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It normally costs around $250 USD
About Scope Tube Sealing and Gas Purging
Wetness inside your rifle glass can ruin a day of shooting and your highly-priced optic by inducing fogging and generating residue within the scope tube. Many optics prevent moisture from going into the scope tube with a series of sealing O-rings which are water resistant. Typically, these water resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture content avoidance for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle on boats and are concerned about the optic still performing if it is submerged in water and you can still retrieve the gun.
What to Know About Rifle Optic Tube Gas Purging
Another element of preventing the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the glass is less affected by temp changes and pressure distinctions from the outside environment which may possibly permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
