Facts About Rifle Scopes
Rifle scopes enable you to precisely align a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through zoom by employing a set of lenses inside the scope. The scope’s alignment can be adjusted to take into account many environmental aspects like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the target. A lot of modern rifle scopes and optics have around 11 parts which are arranged within and on the exterior of the scope. These scope parts include the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other elements. See all eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the perfect type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are very little
- Experienced shooters who recognize their aim point “hold over” plus “lead” relationships for their weapon
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. This causes the reticle to stay at the exact same size in relation to the quantity of zoom being used. The effect is that the reticle measurements shift based upon the zoom used to shoot over lengthier ranges because the markings represent various increments which can vary with the zoom. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular varieties of scopes are useful for:
- Far away forms of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots occur within much shorter spaces and ranges
- Shooters who prefer a clearer optic picture with less space taken up by the larger size FFP reticle
The quantity of zoom a scope offers is figured out by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
About Single Power Lens Glass
A single power rifle optic comes with a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not change given that it is set from the factory.
Variable Power Lens Scope Info
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification degree in a format such as 2-10×32. These numbers mean the magnification of the scope can be set in between 2x and 10x power. This always includes the power levels in-between 2 and 10. The power adaptation is accomplished by operating the power ring component of the scope near the back of the scope by the eye bell piece.
The Power Level and Range Correlation of Rifle Optics
Here are some recommended scope power settings and the distances where they may be efficiently used. High power rifle scope glass will not be as effective as lower powered optics considering too much zoom can be a negative aspect depending on your shooting distance. The same concept relates to extended ranges where the shooter needs increased power to see exactly where to best aim the rifle at the target.
About Lens Finish
All contemporary rifle optic and scope lenses are coated. There are various types and qualities of glass finishes. When thinking about high end rifle scope units, Lens coating can be an important element of a rifle. The glass lenses are one of the most essential components of the glass since they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses safeguards the lens exterior and also assists with anti glare from refracted sunshine and color profiles.
Details on Rifle Glass Lens Coatings – HD Versus ED
Some optic makers will also use “HD” or high-definition glass finishings that take advantage of different procedures, polarizations, rare earth compounds, and components to enhance a wide range of colors and viewable definition through the lens. This high-definition coating is commonly used with increased density glass which drops light’s chance to refract through the lens glass. Some scope manufacturers use “HD” to describe “ED” signifying extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration may be noticeable over objects with hard edges and outlines as light hits the object from certain angles.
Single Finish Versus Multi-Coating
Various optic lenses can even have various finishes applied to them. All lenses generally have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic assembly. This is since the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in many kinds of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can protect 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 coated 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 coated or “multi” covered. Being “much better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Hydrophobic Lens Coating
Water on a lens does not support retaining a clear sight picture through an optic at all. Lots of top of the line and premium optic producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the surface of the Steiner glass lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Alternatives for Mounting Optics on Firearms
Installing solutions for scopes can be found in a few options. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also generally are made in quick release variations which use throw levers which enable rifle shooters to rapidly mount and dismount the scope.
Hex Key Rifle Scope Ring Mounts
Basic, clamp-on style mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on rifles. These forms of scope mounts use a pair of individual rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are developed for far away accuracy shooting. This form of scope mount is ideal for rifles which are in need of a durable, unfailing mount which will not change despite how much the scope is moved or abuse the rifle takes. These are the design of mounts you really want to have for a faithful scope setup on a reach out and touch someone hunting or competitors rifle which will almost never need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to protect against the hex screw threads from wiggling out after they are installed tightly in place. An example of these mounting rings are the 30mm style from the Vortex Optics brand. The set normally costs around $200 USD
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and attach it to a different rifle. Several scopes can also be switched out if they all use a similar design mount. These types of mounts are convenient for rifle platforms which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used in between multiple rifles or are situationally focused.
Info on Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your pricey optic by bringing about fogging and creating residue inside of the scope tube. Most scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Details on Rifle Optic Tube Gas Purging
Another part of preventing the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is currently taken up by the gas, the scope is less altered by temperature shifts and pressure distinctions from the external environment which could possibly enable water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
