Info Rifle Optics
Rifle scopes enable you to precisely align a rifle at various targets by lining up your eye with the target at range. They do this through zoom by using a set of lenses within the scope. The scope’s positioning can be adapted for consideration of separate ecological aspects like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will land based on the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the target. Many modern rifle scopes have around eleven parts which are arranged within and outside of the scope. These scope parts include the rifle scope’s body, lenses, windage dials, objective focus rings, and other elements. Learn about the eleven parts of glass.
About Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the perfect type of rifle optic is based around what type of shooting you plan to do.
First Focal Plane Scope Details
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are minimal
- Experienced shooters who recognize their target “hold over” plus “lead” ratios for their long guns
- Shooters who do not mind the reticle is bigger and takes up more visual sight space than a SFP reticle
Second Focal Plane Glass Info
Second focal plane optics (SFP) include the reticle behind the magnifying lens. This triggers the reticle to remain at the same overall size in connection with the amount of magnification being used. The final result is that the reticle dimensions alter based upon the magnification used to shoot over greater distances due to the fact that the reticle measurements present different increments which can vary with the zoom. 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 reticle measurement. These particular varieties of glass work for:
- Far away styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots take place within much shorter ranges and proximities
- Shooters who want a clearer optic sight picture without space taken up by the larger size FFP reticle
Zoom for Scopes
The amount of magnification a scope supplies is identified 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.
Fixed Single Power Lens Optic Info
A single power rifle optic and scope will have a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not change considering that it is fixed.
About Adjustable Power Lens Glass
Variable power rifle scopes use variable power levels. The power change is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Optic Power Level and Range Correlation
Here are some advised scope power settings and the ranges where they may be successfully used. Bear in mind that high power scopes will not be as practical as lower powered scopes since excessive zoom can be a bad thing. The same idea applies to longer distances where the shooter needs sufficient power to see exactly where to best aim the rifle at the target.
About Lens Finishes
All state-of-the-art rifle scope and optic lenses are layered. Lens finishing can be an important element of a rifle when considering high end rifle optics and scope systems.
Info on Lens Coatings – HD Versus ED
Some scope brands also use “HD” or high-definition lens coatings which use different methods, components, polarizations, and chemicals to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Coating Versus Multi-Coating
Different optic lenses can also have different finishes applied to them. All lenses generally have at least some type of treatment or coating used to them before they are used in a rifle scope or optic.
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 maker and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are layered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle scope.
Hydrophobic Lens Coating
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic covering.
Scope Mounting Options
Mounting solutions for scopes are available in a couple of choices. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually come in quick release versions which use throw levers which permit rifle shooters to rapidly install and remove the scopes.
Hex Key Rifle Scope Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope install is fine for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Scope Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can also be switched out. 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 permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining precision. These kinds of mounts are useful and convenient for shooting platforms which are transferred between vehicles a lot, to remove the optic from the rifle for protection, or for sight systems which are employed in between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle optic can mess up a day of shooting and your costly optic by causing fogging and producing residue inside of the scope tube. The majority of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Info Around Scope Tube Gas Purging
Another component of preventing the accumulation of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the optic is less impacted by temperature level alterations and pressure differences from the outdoor environment which could 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 look for.
