Rifle scopes permit you to specifically align a rifle at different targets by lining up your eye with the target over a range. They do this through magnification using a set of lenses inside the scope. The scope’s alignment can be adjusted to account for many environmental things like wind speed and elevation to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based upon the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the target. Many modern-day rifle scopes have about 11 parts which are located within and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, elevation dials or turrets, focus rings, and other elements. Learn about the eleven parts of rifle optics.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane an optic has establishes where the reticle or crosshair lies relative to the optic’s magnifying adjustments. It actually suggests the reticle is behind or in front of the magnification lens of the optic. Picking the most ideal style of rifle optic depends upon what sort of shooting or hunting you plan on undertaking.
Info About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are very little
- Experienced shooters who recognize their aim point “hold over” and “lead” equations for their firearm
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. This triggers the reticle to stay at the same scale relative to the volume of zoom being used. The end result is that the reticle dimensions alter based on the magnification used to shoot over lengthier ranges given that the markings represent different increments which change with the zoom. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick. These particular kinds of scopes are handy for:
- Long distance styles of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots occur within shorter ranges and distances
- Shooters who desire a clearer optic sight picture with less area used up by the enlarged FFP reticle
Ins and Outs of Rifle Optic Zoom
The measure of scope magnification you need on your optic is based on the type of shooting you like to do. Nearly every style of rifle glass delivers some level of zoom. The amount of zoom a scope gives is determined by the dimension, density, and curvatures of the lenses within the rifle scope. The zoom of the scope is the “power” of the opic. This suggests what the shooter is looking at through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Info on Fixed Power Lens Rifle Glass
A single power rifle scope uses a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not adjust considering that it is fixed.
Info About Adjustable Power Lens Scopes
Variable power rifle scopes use variable power levels. The power modification is handled by making use of the power ring part of the scope near the back of the scope by the eye bell.
Rifle Glass Power Level and Range Correlation
Here are some recommended scope power settings and the distances where they can be successfully used. High power optics will not be as useful as lower powered glass given that too much zoom can be a negative aspect depending on your shooting distance. The same concept applies to longer ranges where the shooter needs enough power to see exactly where to best aim the rifle.
Details on Lens Finish
All contemporary rifle scope lenses are coated. There are different types and qualities of glass lens finishes. Lens finish can be an important element of a rifle when looking at high end rifle optics and scope systems. The lenses are one of the most critical parts of the glass due to the fact that they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses shields the lens exterior as well as helps with anti glare from excess natural light and color visibility.
About Rifle Glass Lens Coatings – HD Versus ED
Some glass suppliers also use “HD” or high-def glass coatings which employ different processes, components, polarizations, and chemicals to draw out numerous color ranges and viewable target visibility through the lens. This high-definition finishing is frequently used with more costly high density glass which brings down light’s chance to refract through the lens glass. Some scope brands use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration is often obvious around things with hard outlines as light hits the object from specific angles.
Rifle Glass Lens Single Finishing Versus Multi-Coating
Various scope lenses can also have different finishings applied to them. All lenses generally have at least some kind of treatment or coating applied to them before being 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 requires a coating to be applied to it so that it will be efficiently functional in numerous kinds of environments, degrees of light (full VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. 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 covered lens depends upon the scope developer and how much you spent on it. Both are indications of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” covered. Being “better” depends on the producer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Anti-water Lens Coating
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Many top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic covering.
Rifle Glass Mounting Alternatives
Mounting approaches for scopes can be found in a few choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally come in quick release versions which use throw levers which permit rifle operators to rapidly install and dismount the optics.
Hex Key Glass Ring Mounts
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 different rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range precision shooting. This type of scope mount is great for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly take off a scope and attach it to a different rifle. Several scopes can also be swapped out if they all use a compatible design mount. These types of mounts are convenient for rifles which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between multiple rifles or are situationally focused.
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. Most scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Details on Rifle Scope Tube Gas Purging
Another part of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the scope is less altered by temp shifts and pressure distinctions from the outdoor environment which might possibly allow 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 seek out.
