Information About Glass
Rifle scopes enable you to exactly aim a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through magnifying the target by employing a series of lenses inside the scope. The scope’s positioning can be adjusted to account for separate natural factors like wind speed and elevation to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based upon the sight picture you are seeing via the scope as you align the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle scopes have around eleven parts which are arranged within and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, elevation turrets, focus rings, and other elements. Learn about the eleven parts of scopes.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has establishes where the reticle or crosshair is located in relation to the optic’s magnifying adjustments. It actually implies the reticle is situated behind or ahead of the magnifying lens of the optic. Looking for the most beneficial kind of rifle glass is based on what variety of hunting or shooting you plan on doing.
First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are small
- Experienced shooters who recognize their aim point “hold over” and “lead” correlations for their long guns
- Shooters who do not mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane glass (SFP) include the reticle behind the magnification lens. This induces the reticle to remain at the exact same size relative to the amount of magnification being used. The end result is that the reticle dimensions alter based upon the zoom chosen to shoot over lengthier ranges given that the reticle measurements represent different increments which vary with the zoom. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick. These kinds of scopes work for:
- Far away forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots occur within shorter ranges and proximities
- Shooters who want a clearer optic picture without area taken up by the larger sized FFP reticle
Details on Rifle Scope Zoom
The amount of scope magnification you need on your glass depends upon the type of shooting you desire to do. Virtually every type of rifle optic gives some degree of zoom. The level of magnification a scope offers is determined by the size, thickness, and curvatures of the lenses within the rifle optic. The magnification of the scope is the “power” of the opic. This denotes what the shooter is observing through the scope is amplified times the power factor of what can normally be seen by human eyes.
Fixed Single Power Lens Optic Info
A single power rifle optic comes with a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not fluctuate since it is a set power scope.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be changed between magnification increments. These types of scopes will list the magnification amount in a configuration like 2-10×32. These numbers mean the magnification of the scope could be adjusted between 2x and 10x power. This additionally utilizes the powers in-between 2 and 10. The power manipulation is accomplished by working with the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power Level and Ranges
Here are some advised scope power settings and the distances where they can be efficiently used. Consider that higher magnification glass will not be as effective as lower magnification level scopes since too much magnification can be a negative thing in certain situations. The exact same concept applies to extended distances where the shooter needs adequate power to see precisely where to best aim the rifle.
Info on Lens Finishes
All present day rifle scope and optic lenses are covered. Lens finishing can be a vital element of a rifle’s setup when looking at high end rifle optics and scope equipment.
HD Versus ED Rifle Optic Lens Coatings
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use different processes, chemicals, components, and polarizations to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Rifle Glass
Different optic lenses can likewise have different coatings applied to them. All lenses normally have at least some type of treatment or finishing used to them before they are used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can protect 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 maker and just how much you paid for it. The scope’s maker and cost are indications of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” coated. Being “much better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Hydrophobic Rifle Scope Lens Finish
Water on an optical lens does not help with keeping a clear sight picture through a scope in any way. Lots of top of the line or premium optic producers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It treats the surface of the Steiner scope lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Rifle Optic Installation Alternatives
Mounting solutions for scopes come in a couple of options. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also typically can be found in quick release variations which use manual levers which allow rifle operators to quickly install and remove the glass.
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 different rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long range precision shooting. This type of scope install is wonderful for rifles which require a resilient, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle. If they all use a similar style mount, several scopes can often be swapped out. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten solidly 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 preserving accuracy. These kinds of mounts are useful and beneficial for rifles which are moved a lot, to remove the scope glass from the rifle for protection, or for aiming systems which are used between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle scope can ruin a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. The majority of scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Optic Tubes
Another part of avoiding the buildup of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is currently taken up by the gas, the scope is less impacted by temperature level shifts and pressure distinctions from the external environment which could potentially allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
