Rifle Scope Facts
Rifle scopes permit you to exactly align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnification by employing a series of lenses inside the scope. The scope’s positioning can be dialed in for consideration of many environmental aspects like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based upon the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes and optics have around 11 parts which are found inside and outside of the scope. These parts include the rifle scope’s body, lenses, modification dials, focus rings, and other components. Learn about the eleven parts of rifle optics.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Opting for the best type of rifle scope is based on what type of shooting you plan on doing.
First Focal Plane Glass
Focal plane scopes (FFP) come with 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 result is that the reticle measurements are the same at the enhanced distance as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are low
- Experienced shooters who have an idea for their target “hold over” and “lead” correlations for their firearms
- Shooters who don’t mind the reticle is bigger and occupies more visual sight area than a SFP reticle
Second Focal Plane Glass Info
Second focal plane glass (SFP) come with the reticle to the rear of the magnifying lens. This triggers the reticle to stay at the exact same overall size in connection with the level of zoom being used. The outcome is that the reticle dimensions shift based upon the zoom chosen to shoot over lengthier ranges considering that the reticle measurements present distinct increments which can vary with the magnification. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick. These sorts of scopes work for:
- Far away styles of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots take place within shorter ranges and spaces
- Shooters who would like a clearer optic picture without room taken up by the larger sized FFP reticle
Rifle Scope Zoom
The amount of zoom a scope offers is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Info About Single Power Lens Rifle Optics
A single power rifle scope and optic uses a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change given that it is fixed.
Variable Power Lens Scope Info
Variable power rifle scopes use enhanced power. The power modification is handled by the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some recommended scope power levels and the ranges where they can be successfully used. Keep in mind that high magnification glass will not be as efficient as lower powered glass due to the fact that too much zoom can be a bad thing. The exact same concept goes for longer distances where the shooter needs to have sufficient power to see where to best aim the rifle.
About Lens Coating
All cutting-edge rifle glass lenses are coated. Lens coating is a significant element of a rifle’s setup when buying high end rifle optics and scope systems.
HD Versus ED Rifle Glass Lens Coatings
Some rifle scope suppliers also use “HD” or high-def lense finishes which make the most of different procedures, polarizations, elements, and chemicals to extract separate color ranges and viewable target visibility through lenses. This high-def covering is normally used with greater density glass which brings down light’s capability to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” meaning extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration can be noticeable over items with defined outlines as light hits the object from particular angles.
Optic Lens Single Coating Versus Multi-Coating
Different scope lenses can also have various finishes applied to them. All lenses typically have at least some kind of treatment or covering applied to them before they are used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It needs to have a covering placed on it so that the lens will be efficiently usable in many types of environments, degrees of sunshine (full VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of products used in constructing the rifle scope.
Optic Lens Hydrophobic Covering
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic anti-water covering.
Rifle Optic Mounting Options
Installing options for scopes come in a few choices. 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 normally can be found in quick release variations which use manual levers which permit rifle shooters to rapidly mount and remove the glass.
Scope Mounts with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long range accuracy shooting. This type of scope mount is wonderful for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and connect it to a different rifle. Several scopes can even be switched out if they all use a compatible style mount. These types of mounts are convenient for rifle platforms which are carried a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between numerous rifles.
Info on Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can spoil a day on the range and your costly optic by causing fogging and producing residue within the scope’s tube. Most scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are waterproof. Generally, these optics can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity avoidance for common use rifles, unless you intend on taking your rifle on boats and are worried about the scope still performing if it goes over the side and you can still rescue the rifle.
About Rifle Optic Tube Gas Purging
Another element of avoiding the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the optic is less affected by temperature level changes and pressure differences from the external environment which could possibly permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
