Rifle Optic Info
Rifle scopes allow you to specifically align a rifle at different targets by aligning your eye with the target over a range. They accomplish this through magnification by employing a series of lenses within the scope. The scope’s alignment can be adapted for consideration of separate environmental factors like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many contemporary rifle scopes and optics have around eleven parts which are found internally and externally on the optic. These parts consist of the rifle scope’s body, lenses, modification turrets, objective focus rings, and other elements. See all eleven parts of scopes.
About Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the perfect type of rifle glass is based around what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are minimal
- Experienced shooters who recognize their aim point “hold over” plus “lead” relationships for their rifles
- Shooters who do not mind the reticle is bigger and requires more visual sight space than a SFP reticle
Second Focal Plane Scope Details
Second focal plane scopes (SFP) come with the reticle to the rear of the magnifying lens. This triggers the reticle to stay at the very same overall size in connection with the amount of zoom being used. The effect is that the reticle measurements adapt based on the magnification applied to shoot over greater ranges considering that the markings represent different increments which differ with the zoom level. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement. These styles of optics are handy for:
- Long distance forms of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots happen within shorter ranges and proximities
- Shooters who like a clearer optic sight picture without room taken up by the enlarged FFP reticle
Glass Magnification
The measure of scope zoom you need on your optic depends on the form of shooting you like to do. Just about every kind of rifle scope provides some amount of zoom. The amount of magnification a scope provides is determined by the size, thickness, and curvatures of the lenses inside of the rifle optic. The magnifying level of the optic is the “power” of the opic. This suggests 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 Fixed Power Lens Optics
A single power rifle scope or optic will have a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not fluctuate since it is set from the factory.
Variable Power Lens Rifle Scope Facts
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom amount in a configuration like 2-10×32. These numbers imply the magnification of the scope can be set between 2x and 10x power. This always incorporates the power levels in-between 2 and 10. The power manipulation is accomplished by operating the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power and Range Correlation of Rifle Scopes
Here are some suggested scope power settings and the ranges where they may be successfully used. High power glass will not be as effective as lower powered glass due to the fact that too much zoom can be a negative aspect depending on your shooting distance. The exact same concept applies to extended ranges where the shooter needs to have adequate power to see precisely where to best aim the rifle at the target.
Rifle Glass Lens Finish
All modern rifle optic and scope lenses are covered in special coatings. There are different types and qualities of coverings. Lens finish can be an essential aspect of a rifle’s setup when considering high end rifle optics and scope systems. The lenses are one of the most key parts of the glass considering that they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses offers protection to the lens exterior as well as helps with anti glare capabilities from excess natural light and color recognition.
Info on Lens Coatings – HD Versus ED
Some glass companies even use “HD” or high-definition lense finishings which take advantage of different processes, rare earth compounds, components, and polarizations to extract separate color ranges and viewable definition through lenses. This high-definition finishing is commonly used with higher density lens glass which lowers light’s opportunity to refract by means of the lens glass. Some scope manufacturers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how 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 over items with hard shapes as light hits the item from specific angles.
Single Finish Versus Multi-Coating for Rifle Glass
Different optic lenses can also have different finishings applied to them. All lenses usually have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It needs to have a finish placed on it so that the lens will be optimally usable in lots of kinds of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope producers similarly make it a point to specify if their optic lenses are layered or “multi” coated. Being “much better” depends on the producer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Anti-water Rifle Optic Lens Finish
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Lots of top of the line and military grade scope companies will coat their lenses with a hydrophobic or hydrophilic covering.
Choices for Installing Rifle Scopes on Long Guns
Installing options for scopes can be found in a few options. There are the basic scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also generally can be found in quick release versions which use throw levers which allow rifle operators to rapidly mount and remove the scope.
Hex Key Glass Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long range precision shooting. This type of scope mount is fine for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and attach it to a different rifle. Multiple scopes can even be switched out if they all use a compatible style mount. These types of mounts are convenient for rifles which are transferred a lot, to swap out the optic from the rifle for protection, or for optics which are used in between multiple rifles.
About Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can wreck a day on the range and your costly optic by inducing fogging and developing residue inside of the scope tube. A lot of optics protect against humidity from entering the scope tube with a series of sealing O-rings which are waterproof. Typically, these water-resistant scopes can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture content prevention for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle on your motorboat and are worried about the optic still working if it falls overboard and you can still rescue the gun.
Scope Gas Purging
Another component of preventing the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the optic is less affected by temp changes and pressure differences from the external environment which could possibly allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
