Rifle Scope Information
Rifle scopes enable you to specifically align a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnification by using a series of lenses within the scope. The scope’s positioning can be adjusted to account for separate ecological elements like wind and elevation to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based on the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the target. The majority of modern rifle optics have around eleven parts which are located internally and outside of the scope. These parts consist of the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of rifle glass.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane an optic has decides where the reticle or crosshair lies in regard to the optic’s magnification. It literally suggests the reticle is situated behind or in front of the magnification lens of the optic. Choosing the best style of rifle optic is based upon what style of shooting you plan on doing.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where computations are very little
- Experienced shooters who understand their aim point “hold over” plus “lead” ratios for their firearm
- Shooters who don’t mind the reticle is bigger and requires more visual sight room than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Far away types of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots take place within much shorter proximities and ranges
- Shooters who choose a clearer optic sight picture without room taken up by the enlarged FFP reticle
Rifle Scope Magnification
The quantity of scope magnification you require depends on the kind of shooting you plan to do. Practically every kind of rifle scope offers some amount of magnification. The quantity of magnification a scope supplies is determined by the size, thickness, and curvatures of the lenses inside of the rifle optic. The magnifying level of the scope is the “power” of the opic. This means what the shooter is observing through the scope is magnified times the power aspect of what can normally be seen by human eyes.
Info About Single Power Lens Scopes
A single power rifle scope or optic comes with a magnification number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not change since it is fixed.
Info on Adjustable Power Lens Optics
Variable power rifle scopes can be tweaked between magnified settings. The power adjustment is handled by using the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range of Optics
Here are some suggested scope power levels and the distances where they can be efficiently used. High power glass will not be as efficient as lower powered optics considering that too much magnification can be a bad thing. The very same idea applies to longer ranges where the shooter needs to have sufficient power to see exactly where to properly aim the rifle at the target.
Lens Coating for Scopes
All present day rifle optic lenses are layered. Lens finishing can be a crucial aspect of a shooting system when purchasing high end rifle optics and scope systems.
About Lens Coatings – HD Versus ED
Some optic suppliers even use “HD” or high-definition glass finishes which make the most of various processes, polarizations, rare earth compounds, and components to extract separate colors and viewable target visibility through lenses. This high-def finishing is typically used with greater density lens glass which drops light’s ability to refract by means of the lens glass. Some scope corporations use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration is often visible over things with hard shapes as light hits the object from various angles.
Single Covering Versus Multi-Coating for Rifle Glass
Various optic lenses can even have different coverings applied to them. All lenses usually have at least some kind of treatment or coating applied to them before being used in a rifle scope or optic. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently functional in lots of kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing 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 the amount you spent on it. Both are indications of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in building the rifle scope.
Hydrophobic Lens Finishing
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Many top of the line and military grade scope makers will coat their lenses with a hydrophobic or hydrophilic coating.
Rifle Optic Installing Choices
Installing solutions for scopes are available in a few options. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also generally come in quick release variations which use throw levers which allow rifle operators to quickly mount and dismount the optics.
Scope Mounts with Hex Key Rings
Basic, clamp-on style mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use a pair of detached rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope mount is exceptional for rifles which need to have a long lasting, rock solid mount which will not shift no matter how much the scope is moved about or jarring the rifle takes. These are the style of mounts you want for a faithful scope system on a long distance hunting or interdiction long gun that will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the mount screws to prevent the hex screw threads from backing out after they are installed tightly in position. An example of these rings are the 30mm type made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle. Several scopes can also be switched out if they all use a similar style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten tightly to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining precision. These types of mounts are useful and handy for rifles which are transferred between vehicles a lot, to remove the glass from the rifle for protection, or for scopes which are employed between multiple rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It normally costs around $250 USD
Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day on the range and your highly-priced optic by resulting in fogging and creating residue inside of the scope’s tube. The majority of optics prevent moisture from going into the optical tube with a system of sealing O-rings which are waterproof. Typically, these optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of humidity prevention for basic use rifles, unless you plan on taking your rifle on a boat and are worried about the optic still performing if it falls overboard and you can still find the rifle.
Gas Purged Optic Tubes
Another part of avoiding the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the scope is less impacted by condition alterations and pressure differences from the external environment which might possibly permit water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
