Optic Info
Rifle scopes enable you to specifically align a rifle at various targets by lining up your eye with the target over a distance. They do this through magnification using a set of lenses inside the scope. The scope’s positioning can be dialed in to take into account many ecological considerations like wind and elevation decreases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle scopes and optics have about eleven parts which are found internally and on the exterior of the scope. These parts consist of the rifle scope’s body, lenses, windage turrets, objective focus rings, and other components. See all eleven parts of a scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the best type of rifle glass is based on what type of shooting you plan to do.
First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are small
- Experienced shooters who know their target “hold over” as well as “lead” relationships for their rifles
- Shooters who do not mind the reticle is bigger and requires more visual sight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away forms of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots happen within much shorter ranges and distances
- Shooters who choose a clearer optic picture without space taken up by the larger sized FFP reticle
Rifle Scope Zoom
The amount of scope magnification you need on your scope depends on the kind of shooting you plan to do. Nearly every kind of rifle glass gives some amount of magnification. The amount of zoom a scope offers is established by the dimension, density, and curves of the lenses inside of the rifle optic. The magnification level of the optic is the “power” of the scope. This suggests what the shooter is aiming at through the scope is magnified times the power element of what can typically be seen by human eyes.
Fixed Power Lens Rifle Scopes
A single power rifle scope and optic will have a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate considering that it is a fixed power optic.
Adjustable Power Lens Optic Info
Variable power rifle scopes use variable power levels. The power change is performed by the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power and Range Correlation
Here are some advised scope power levels and the ranges where they may be effectively used. Bear in mind that higher power optics will not be as practical as lower powered scope and optics due to the fact that excessive zoom can be a detractor. The exact same concept applies to longer distances where the shooter needs to have increased power to see exactly where to best aim the rifle at the target.
Rifle Glass Lens Finish
All contemporary rifle scope and optic lenses are covered in special coatings. There are different types and qualities of coverings. Lens covering can be an essential aspect of a rifle’s setup when looking at luxury rifle optics and scope units. The glass lenses are among the most key components of the scope because they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses safeguards the lens exterior as well as assists with anti glare capabilities from refracted light and color profiles.
Details on Scope Lens Coatings – HD Versus ED
Some scope manufacturers likewise use “HD” or high-definition lens finishings which use different procedures, chemicals, aspects, and polarizations to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Optics
Various optic lenses can also have different coverings used to them. All lenses normally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. 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 upon the scope manufacturer and how much you spent paying for it. Both the manufacturer and amount are indications of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are layered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of products used in building the rifle scope.
Anti-water Lens Finishes
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Many top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finish.
Scope Installing Choices
Installing options for scopes are available in a few options. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also generally can be found in quick release variations which use manual levers which allow rifle shooters to rapidly install and remove the optics.
Rifle Optic Mounts with Hex Key Rings
Basic, clamp-on type mounting scope rings use hex head screws to install to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two detached rings to support the optic, and are made from 7075 T6 billet aluminum which are made for long distance precision shooting. This type of scope mount is very good for rifle systems which require a durable, rock solid mount which will not change regardless of how much the scope is moved about or abuse the rifle takes. These are the style of mounts you should have for a dedicated optics setup on a reach out and touch someone scouting or sniper competition firearm which will seldom 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 screws from wiggling out after they are installed safely in position. An example of these mounting rings are the 30mm style made by the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be switched out if they all use a compatible design mount. These types of mounts are convenient for rifles which are carried 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.
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle scope can ruin a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. Most scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
About Scope Tube Gas Purging
Another component of avoiding the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the glass is less altered by temp changes and pressure variations from the outdoor environment which might possibly enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
