Rifle Scope Facts
Rifle scopes allow you to precisely aim a rifle at different targets by aligning your eye with the target over a distance. They do this through zoom by employing a series of lenses within the scope. The scope’s alignment can be adjusted to take into account varied natural factors like wind and elevation increases to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based upon the sight picture you are seeing with the scope as you line up 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 found inside and on the exterior of the scope. These parts consist of the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other elements. Learn about the eleven parts of glass.
About Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the optimal type of rifle optic depends on what type of shooting you plan to do.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This induces 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 amplified range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at one hundred yards by using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are small
- Experienced shooters who understand their aim point “hold over” and “lead” equations for their long gun
- Shooters who do not mind the reticle is enlarged and takes up more visual sight space than a SFP reticle
Second Focal Plane Glass Info
Second focal plane scopes (SFP) feature the reticle behind the magnification lens. This triggers the reticle to remain at the very same size in connection with the quantity of zoom being used. The effect is that the reticle measurements alter based upon the zoom employed to shoot over greater ranges since the markings present various increments which can vary with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These types of glass are convenient for:
- Far away styles of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who prefer a clearer optic picture with less space taken up by the larger sized FFP reticle
Rifle Scope Magnification
The amount of zoom a scope provides is determined by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Fixed Single Power Lens Rifle Optics
A single power rifle optic or scope comes with a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate because it is fixed.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be modified between magnified levels. The power adjustment is performed by the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range
Here are some advised scope power settings and the distances where they could be effectively used. High power rifle scope glass will not be as effective as lower magnification glass because too much zoom can be a bad thing. The exact same concept goes for extended distances where the shooter needs to have increased power to see exactly where to best aim the rifle at the target.
Lens Coating for Glass
All present day rifle scope lenses are layered. Lens coating is a crucial aspect of a rifle’s setup when considering high end rifle optics and scope setups.
HD Versus ED Lenses
Some rifle glass producers even use “HD” or high-def lens coverings which make the most of various processes, elements, chemical substances, and polarizations to draw out various colors and viewable definition through the lens. This high-definition finish is frequently used with more costly, high density lens glass which drops light’s potential to refract through the lens glass. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be noticeable over objects with well defined outlines as light hits the object from various angles.
Glass Lens Single Finish Versus Multi-Coating
Different optic lenses can also have various coatings applied to them. All lenses typically have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope producer and how much money you spent paying for it. Both the manufacturer and amount are signs of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Anti-water Lens Coating
Water on a scope lens does not improve preserving a clear sight picture through a scope at all. Lots of top of the line and premium 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 treats the exterior surfaces of the Steiner glass lens so the water molecules can not bind to it or create surface tension. The outcome is that the water beads move off of the scope to preserve a clear, water free sight picture.
Options for Mounting Rifle Glass on Firearms
Installing options for scopes come in a couple of choices. There are the basic scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also usually come in quick release versions which use throw levers which enable rifle operators to rapidly mount and dismount the scope.
Scope Mounts with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on the tops of rifles. These types of scope mounts use two independent rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are developed for long distance precision shooting. This form of scope mount is excellent for rifle systems which require a long lasting, rock solid mount which will not move no matter how much the scope is moved about or jarring the rifle takes. These are the design of mounts you really want to have for a faithful optics system on a far away scouting or competition long gun which will seldom need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to keep the hex screws from backing out after they are installed firmly in position. An example of these rings are the 30mm style made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly detach a scope and connect it to a different rifle. Several scopes can even be swapped out if they all use a similar design mount. These types of mounts come in handy for long guns which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are used in between numerous rifles or are situationally focused.
Info Around Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can mess up a day on the range and your pricey optic by triggering fogging and producing residue inside of the scope tube. The majority of optics prevent moisture from entering the optical tube with a system of sealing O-rings which are waterproof. Typically, these water resistant scopes can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture prevention for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard watercrafts and are concerned about the scope still functioning if it is submerged in water and you can still find the firearm.
Gas Purged Scope Tubes
Another component of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less affected by temperature alterations and pressure differences from the outdoor environment which may possibly permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
