Information Glass
Rifle scopes enable you to precisely align a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through magnification by employing a set of lenses inside the scope. The scope’s alignment can be adapted to take into account various natural considerations like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the target. Most modern-day rifle scopes have around 11 parts which are arranged inside and externally on the scope. These scope parts include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other elements. Learn about the eleven parts of rifle glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The type of focal plane a scope has identifies where the reticle or crosshair is located in connection with the optic’s magnifying adjustments. It simply indicates the reticle is situated behind or ahead of the magnification lens of the optic. Considering the most suitable form of rifle optic is dependent on what sort of shooting you intend on undertaking.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the extent of zoom being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are marginal
- Experienced shooters who recognize their target “hold over” and “lead” relationships for their long guns
- Shooters who don’t mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification 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 styles of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots occur within shorter spaces and ranges
- Shooters who like a clearer optic picture with less area taken up by the larger sized FFP reticle
About Scope Magnification
The quantity of magnification a scope offers is determined by the size, density, 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 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 zoom of this kind of optic can not adjust since it is set from the factory.
Info on Adjustable Power Lens Rifle Optics
Variable power rifle scopes use enhanced power. The power adjustment is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some recommended scope power settings and the ranges where they can be successfully used. Bear in mind that high power glass will not be as efficient as lower magnification level scopes since too much zoom can be a bad thing. The exact same concept relates to extended ranges where the shooter needs to have enough power to see where to properly aim the rifle.
Info on Lens Finishing
All top of the line rifle glass lenses are layered. Lens covering is an essential element of a rifle’s setup when considering high end rifle optics and scope systems.
ED Versus HD Glass
Some glass makers also use “HD” or high-definition lense finishes which use various procedures, polarizations, rare earth compounds, and elements to extract separate colors and viewable target definition through the lens. This HD finishing is typically used with increased density glass which decreases light’s opportunity to refract through the lens glass. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration is often obvious over objects with defined shapes as light hits the object from specific angles.
Single Coating Versus Multi-Coating
Various scope lenses can even have different finishes applied to them. All lenses usually have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many types of environments, degrees of light (full VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can safeguard the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope maker and how much you paid for it. Both the manufacturer and amount are signs of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” covered. Being “much better” depends on the maker’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Details on Hydrophobic Finish
Water on a scope lens does not improve keeping a clear sight picture through an optic in any way. Numerous top of the line and premium optic makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the exterior of the Steiner scope lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads move off of the scope to maintain a clear, water free sight picture.
Alternatives for Installing Optics on Firearms
Mounting solutions for scopes can be found in a few options. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically come in quick release versions which use toss levers which enable rifle shooters to quickly install and dismount the scopes.
Hex Key Optic 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 two separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope mount is excellent for rifles which require a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, several scopes can also be switched out in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining the original sighting settings. These types of mounts come in convenient for shooting platforms which are transported a lot, to remove the scope glass from the rifle for protection, or for scopes which are used between multiple rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It normally costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by bringing about fogging and creating residue inside of the scope tube. A lot of scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are waterproof.
Optic Gas Purging
Another part of preventing the accumulation of wetness 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 glass is less affected by temperature level shifts and pressure distinctions from the external environment which could potentially allow water vapor to leak 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.
