Rifle Glass Info
Rifle scopes allow you to specifically align a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification using a set of lenses inside the scope. The scope’s positioning can be adapted for the consideration of many ecological elements like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the target. A lot of modern rifle scopes have about eleven parts which are located inside and on the exterior of the scope body. These parts include the rifle scope’s body, lenses, elevation turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of rifle scopes.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the finest type of rifle scope is based around what type of shooting you plan to do.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are minimal
- Experienced shooters who know their target “hold over” and also “lead” relationships for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the zoom lens. This triggers the reticle to stay at the exact same overall size in connection with the volume of zoom being used. The end result is that the reticle dimensions alter based on the magnification used to shoot over lengthier distances considering that the reticle markings represent distinct increments which differ with the magnification level. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These sorts of glass are convenient for:
- Long distance types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots occur within shorter ranges and proximities
- Shooters who want a clearer optic picture without room used up by the enlarged FFP reticle
Magnification for Rifle Scopes
The amount of zoom a scope offers 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 Rifle Optics
A single power rifle scope and optic comes with a zoom 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 scope can not adjust considering that it is set from the factory.
About Variable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. It will note the zoom amount in a format like 2-10×32. These numbers imply the zoom of the scope could be changed between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power adjustment is accomplished using the power ring component of the scope near the rear of the scope by the eye bell piece.
Rifle Glass Power and Range Correlation
Here are some recommended scope powers and the ranges where they could be successfully used. Highly magnified scopes will not be as effective as lower powered scopes because too much zoom can be a negative aspect depending on your shooting distance. The same goes for longer ranges where the shooter needs enough power to see exactly where to properly aim the rifle.
Lens Covering for Rifle Glass
All current rifle glass lenses are covered. Lens finish is a vital element of a rifle system when buying high end rifle optics and scope setups.
HD Versus ED Lenses
Some scope manufacturers also use “HD” or high-definition lens coatings which use different methods, components, chemicals, and polarizations to draw out different colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
About Single Coating Versus Multi-Coating
Various optic lenses can even have different finishes applied to them. All lenses typically have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It needs to have a coating placed on it so that the lens will be efficiently usable in many kinds of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less helpful 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 producers similarly make it a point to define if their optic lenses are coated or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle scope.
Hydrophobic Rifle Optic Lens Finishing
Water on a scope’s lens does not assist with maintaining a clear sight picture through a scope in any way. Many top of the line or premium optic manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the exterior of the Steiner optic lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Options for Installing Scopes on Long Guns
Installing approaches for scopes come in a couple of options. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally can be found in quick release variations which use manual levers which allow rifle operators to rapidly install and remove the optics.
Hex Key Rifle Glass Ring Mounts
Normal, clamp style 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 two different rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope install is perfect for rifles which need a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible style mount. These types of mounts are convenient for rifles which are carried a lot, to remove the optic from the rifle for protection, or for optics which are used in between several rifles.
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle optic can destroy a day of shooting and your costly optic by causing fogging and producing 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.
Glass Gas Purging
Another part of preventing the buildup of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the optic is less impacted by temperature level shifts and pressure distinctions from the external environment which may possibly enable water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
