What You Need to Know About Rifle Scopes
Rifle scopes allow you to specifically aim a rifle at various targets by lining up your eye with the target at range. They do this through magnifying the target by employing a set of lenses inside the scope. The scope’s alignment can be dialed in for consideration of various environmental elements like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based upon the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended point of impact. Many contemporary rifle scopes have about 11 parts which are found internally and on the exterior of the scope body. These scope parts include the rifle scope’s body, lenses, windage dials, focus rings, and other elements. See all eleven parts of a scope.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane an optic has decides where the reticle or crosshair lies in regard to the optic’s magnification. It simply means the reticle is situated behind or in front of the magnifying lens of the scope. Picking the best sort of rifle glass depends upon what form of shooting or hunting you intend on doing.
Info on First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This triggers the reticle to increase in size based upon the extent of zoom being used. The result is that the reticle measurements are the same at the amplified range as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the identical tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who understand their target “hold over” and also “lead” equations for their weapon
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight area than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick.
- Far away forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots happen within much shorter spaces and ranges
- Shooters who want a clearer optic sight picture without space used up by the bigger FFP reticle
Zoom for Rifle Optics
The amount of zoom a scope provides is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Fixed Power Lens Optics
A single power rifle optic or scope will have a zoom 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 kind of optic can not fluctuate because it is fixed.
Adjustable Power Lens Glass Details
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification amount in a format such as 2-10×32. These numbers indicate the magnification of the scope could be set between 2x and 10x power. This also utilizes the powers in-between 2 and 10. The power shift is accomplished using the power ring part of the scope near the rear of the scope by the eye bell piece.
Power and Range Correlations
Here are some recommended scope powers and the distances where they may be successfully used. High power rifle scope glass will not be as efficient as lower magnification level rifle scope glass because too much zoom can be a bad thing. The same relates to extended ranges where the shooter needs adequate power to see precisely where to best aim the rifle at the target.
Lens Finish for Rifle Optics
All state-of-the-art rifle scope lenses are layered. Lens coating is a significant element of a rifle system when thinking about high end rifle optics and scope setups.
ED Versus HD Scopes
Some scope makers even use “HD” or high-definition lens finishings which take advantage of various procedures, aspects, compounds, and polarizations to enhance numerous color ranges and viewable definition through lenses. This high-definition finish is normally used with increased density lens glass which brings down light’s chance to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration may be visible around objects with hard edges and shapes as light hits the object from various angles.
Single Scope Lens Finish Versus Multi-Coating
Different optic lenses can also have various coverings applied to them. All lenses usually have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it.
Some scope manufacturers 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 developing the rifle scope.
Hydrophobic Finishing for Rifle Scopes
Water on a scope’s lens does not help with preserving a clear sight picture through an optic in any way. Many top of the line or high-end scope manufacturers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the exterior of the Steiner glass lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to preserve a clear, water free sight picture.
Choices for Mounting Rifle Optics on Firearms
Installing solutions for scopes come in a few choices. There are the basic scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually come in quick release versions which use throw levers which permit rifle shooters to quickly install and dismount the scopes.
Optic Mounting Solutions with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation 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 is designed for long distance accuracy shooting. This type of scope install is great for rifles which require a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Ring Mounts
These kinds of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. If they all use a comparable design mount, several scopes can often be swapped in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping the original sighting settings. These kinds of mounts are useful and practical for rifles which are shipped a lot, to take off the optic from the rifle for protection, or for scopes which are used between numerous rifles. An example of this mount style is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day on the range and your costly optic by triggering fogging and producing residue within the scope tube. Most optics prevent wetness from going into the optical tube with a system of sealing O-rings which are waterproof. Usually, 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 humidity avoidance for common use rifles for hunting and sporting purposes, unless you anticipate taking your rifle boating and are worried about the optic still performing if it goes overboard and you can still salvage the gun.
Details on Rifle Optic Tube Gas Purging
Another part of preventing the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the scope is less altered by temp alterations and pressure distinctions from the external environment which might potentially permit water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
