What You Need to Know About Glass
Rifle scopes allow you to exactly align a rifle at different targets by aligning your eye with the target at range. They do this through zoom by making use of a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of separate natural considerations like wind speed and elevation to account for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based on the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle optics have around eleven parts which are located internally and outside of the scope body. These parts consist of the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other parts. See all eleven parts of a rifle optical system.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has identifies where the reticle or crosshair is located in connection with the optic’s magnifying adjustments. It literally indicates the reticle is located behind or before the magnifying lens of the optic. Picking out the most beneficial sort of rifle glass is based upon what style of hunting or shooting you anticipate undertaking.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are very little
- Experienced shooters who understand their target “hold over” as well as “lead” relationships for their long guns
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) include 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 kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots take place within much shorter proximities and ranges
- Shooters who choose a clearer optic picture without room used up by the bigger FFP reticle
Scope Zoom
The amount of zoom a scope provides 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.
Info About Fixed Single Power Lens Optics
A single power rifle optic and scope uses a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not change because it is fixed.
Variable Power Lens Scopes
Variable power rifle scopes can be changed between magnification increments. It will note the zoom level in a format like 2-10×32. These numbers imply the zoom of the scope can be changed in between 2x and 10x power. This always involves the powers in-between 2 and 10. The power manipulation is achieved by operating the power ring part of the scope near the back of the scope by the eye bell piece.
Power Levels and Range
Here are some recommended scope power settings and the distances where they can be efficiently used. Highly magnified scopes will not be as effective as lower magnification level scopes given that too much zoom can be a negative aspect depending on your shooting distance. The exact same concept relates to extended ranges where the shooter needs to have adequate power to see precisely where to properly aim the rifle.
About Lens Coating
All modern rifle optic and scope lenses are covered in special coatings. There are various types and qualities of finishings. When researching high end rifle targeting units, Lens finish can be a critical component of defining the rifle’s capability. The glass lenses are one of the most important pieces of the scope considering they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses protects the lens surface area and assists with anti glare capabilities from excess sunlight and color exposure.
ED Versus HD Optics
Some rifle scope companies also use “HD” or high-def lense coatings that employ different procedures, aspects, rare earth compounds, and polarizations to enhance a wide range of colors and viewable target definition through the lens. This high-def covering is typically used with increased density glass which drops light’s potential to refract by means of the lens glass. Some scope brands use “HD” to refer to “ED” indicating extra-low dispersion glass. ED handles how colors are represented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration may be obvious around things with hard shapes as light hits the object from specific angles.
Single Coating Versus Multi-Coating for Rifle Optics
Different optic lenses can likewise have different coatings used to them. All lenses generally have at least some type of treatment or covering applied to them before being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. This lens treatment can preserve 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 covered lens depends on the scope company and the amount you paid for it. The scope’s maker and cost are signs of the lens quality.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Glass Lens Anti-water Covering
Water on a scope lens does not improve keeping a clear sight picture through a scope in any way. Many top of the line or premium scope makers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the surface area of the Steiner scope lens so the water molecules can not bind to it or create surface tension. The result is that the water beads roll off of the scope to keep a clear, water free sight picture.
Optic Installation Alternatives
Installing options 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 different types of mounts also typically come in quick release versions which use manual levers which allow rifle shooters to rapidly mount and remove the optics.
Rifle Glass Mounts with Hex Key Rings
Basic, clamp-on design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use a pair of separate rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are developed for long distance precision shooting. This form of scope mount is ideal for rifles which need to have a resilient, unfailing mount which will not shift no matter just how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should have for a dedicated scope system on a far away hunting or tournament long gun that will rarely need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to prevent the hex screws from backing out after they are mounted safely in place. An example of these rings are the 30mm style made by the Vortex Optics brand. The set usually costs around $200 USD
Glass Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle. Multiple scopes can also be switched out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while preserving precision. These types of mounts are useful and handy for rifles which are transported a lot, to take off the glass from the rifle for protection, or for aiming systems which are used between several rifles. An example of this mount style is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Info on Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your costly optic by causing fogging and creating residue within the scope tube. A lot of scopes prevent moisture from going into the optical tube with a series of sealing O-rings which are waterproof. Normally, these scopes can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture content avoidance for standard use rifles, unless you plan on taking your rifle on boats and are concerned about the optic still performing if it is submerged in water and you can still recover the firearm.
About Optic Tube Gas Purging
Another element of avoiding the buildup of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the optic is less impacted by temperature level shifts and pressure distinctions from the external environment which could potentially permit 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 look for.
