Rifle Glass Info
Rifle scopes enable you to exactly aim a rifle at different targets by lining up your eye with the target over a range. They do this through zoom by using a set of lenses within the scope. The scope’s alignment can be adapted for consideration of numerous natural factors like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the target. Many modern-day rifle scopes have about 11 parts which are located within and externally on the optic. These optic pieces include the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other components. Learn about the eleven parts of rifle glass.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane a scope has establishes where the reticle or crosshair lies relative to the scopes zoom. It simply indicates the reticle is behind or before the magnifying lens of the scope. Looking for the most beneficial form of rifle optic is dependent on what kind of shooting or hunting you intend on doing.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are minimal
- Experienced shooters who know their aim point “hold over” plus “lead” correlations for their long guns
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane glass (SFP) come with the reticle behind the magnifying lens. This causes the reticle to remain at the exact same scale in relation to the level of zoom being used. The outcome is that the reticle dimensions adjust based upon the zoom applied to shoot over lengthier distances given that the reticle markings represent different increments which differ with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular styles of glass are handy for:
- Long distance styles of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots take place within shorter proximities and ranges
- Shooters who prefer a clearer optic sight picture with less space taken up by the larger size FFP reticle
Details on Optic Magnification
The extent of scope magnification you need on your glass depends upon the style of shooting you plan to do. Virtually every type of rifle scope delivers some amount of zoom. The amount of magnification a scope offers is established by the diameter, density, and curves of the lens glass inside of the rifle scope. The magnification of the scope is the “power” of the glass. This denotes what the shooter is checking out through the scope is amplified times the power element of what can generally be seen by human eyes.
Fixed Single Power Lens Rifle Glass
A single power rifle scope or optic comes with a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not change since it is a fixed power optic.
Variable Power Lens Optic Info
Variable power rifle scopes can be adjusted between magnification power levels. It will note the magnification amount in a format like 2-10×32. These numbers suggest the zoom of the scope can be changed between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power modification is accomplished utilizing the power ring component of the scope near the rear of the scope by the eye bell piece.
Power and Range Correlations
Here are some suggested scope power levels and the distances where they could be successfully used. High power scopes will not be as effective as lower magnification rifle scope glass given that too much magnification can be a bad thing. The same idea applies to extended distances where the shooter needs increased power to see where to properly aim the rifle at the target.
Info on Optic Lens Finishes
All modern rifle scope lenses are coated. There are different types and qualities of glass coverings. When looking at high end rifle targeting units, Lens coating can be a vital component of defining the capability of the rifle. The lenses are one of the most vital parts of the optic since they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses shields the lens surface area and even assists with anti glare capabilities from excess sunrays and color recognition.
ED Versus HD Scopes
Some scope producers also use “HD” or high-definition lens finishings which use different procedures, aspects, chemicals, and polarizations to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Rifle Glass
Various optic lenses can also have different coverings applied to them. All lenses typically have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope producer and how much you paid for it.
Some scope makers likewise make it a point to define if their optic lenses are covered or “multi” covered. This implies the lens has had several treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can prove that a maker is taking several actions to fight various environmental aspects like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This additionally does not always imply the multi-coated lens will perform better than a single coated lens. Being “much better” depends upon the producer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Hydrophobic Lens Finish
Water on a lens does not assist with retaining a clear sight picture through a scope whatsoever. Numerous top of the line or premium scope makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this type 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 result is that the water beads move off of the scope to keep a clear, water free sight picture.
Choices for Mounting Rifle Optics on Long Guns
Installing solutions for scopes come in a few options. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also generally can be found in quick release variations which use throw levers which permit rifle operators to quickly mount and remove the glass.
Hex Key Optic Rings
Normal, clamp style 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 separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope install is fine for rifles which require a durable, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. If they all use a comparable design mount, a number of scopes can often be switched out in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining accuracy. These kinds of mounts come in practical for rifles which are hauled around a lot, to remove the scope glass from the rifle for protection, or for scopes which are used in between a number of rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle glass can wreck a day on the range and your costly optic by triggering fogging and creating residue within the scope’s tube. Most scopes prevent wetness from getting in the scope tube with a series of sealing O-rings which are water resistant. Generally, these water-resistant optics can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture content prevention for basic use rifles, unless you plan on taking your rifle on boats and are concerned about the scope still performing if it is submerged in water and you can still find the rifle.
Info on Optic Tube Gas Purging
Another component of preventing the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the optic is less influenced by condition changes and pressure variations from the outdoor environment which may potentially allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
