What You Need to Know About Glass
Rifle scopes allow you to exactly align a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnification by utilizing a series of lenses inside the scope. The scope’s alignment can be dialed in to account for numerous environmental elements like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the target. Most contemporary rifle scopes and optics have about eleven parts which are arranged within and outside of the scope body. These optic pieces include the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other elements. Learn about the eleven parts of glass.
About Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the best type of rifle optic is based around what type of shooting you plan on doing.
Info on First Focal Plane Scopes
First focal plane glass (FFP) include the reticle before the magnification lens. This induces the reticle to increase in size based on the level of magnification being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified range. For example, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the same tick at one hundred yards using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are very little
- Experienced shooters who understand their target “hold over” plus “lead” correlations for their long gun
- Shooters who do not mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle behind the magnification lens. This triggers the reticle to remain at the exact same dimensions in relation to the amount of magnification being used. The final result is that the reticle measurements adjust based on the magnification chosen to shoot over lengthier ranges since the markings present different increments which change with the zoom level. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred 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 calculations
- Shooting where most of the shots take place within shorter proximities and ranges
- Shooters who like a clearer optic sight picture without area taken up by the larger size FFP reticle
Magnification for Scopes
The quantity of zoom a scope offers is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Rifle Optic Info
A single power rifle scope uses a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not fluctuate since it is fixed.
Info About Adjustable Power Lens Rifle Optics
Variable power rifle scopes use enhanced power. The power adjustment is achieved by using the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range
Here are some suggested scope power levels and the distances where they could be successfully used. Bear in mind that high magnification scopes and optics will not be as effective as lower powered glass due to the fact that too much zoom can be a detractor. The very same idea applies to extended ranges where the shooter needs to have sufficient power to see precisely where to best aim the rifle at the target.
About Rifle Scope Lens Coatings
All present day rifle optic lenses are coated. Lens covering can be a significant element of a shooting platform when looking at high end rifle optics and scope systems.
HD Versus ED Rifle Optic Lens Coatings
Some scope producers also use “HD” or high-definition lens finishings which use different procedures, chemicals, polarizations, and aspects to draw out a wide range of colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Glass Lens Single Finish Versus Multi-Coating
Various scope lenses can also have various coverings applied to them. All lenses normally have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. 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 lots of types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can preserve 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 on the scope maker and how much you spent for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Hydrophobic Lens Finishes
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic covering.
Choices for Installing Rifle Scopes on Long Guns
Installing options for scopes are available in a couple of choices. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also generally can be found in quick release variations which use throw levers which enable rifle shooters to rapidly mount and remove the scopes.
Optic Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design 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 are designed for long distance accuracy shooting. This type of scope install is fine 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.
Glass Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle. A wide range of scopes can also be swapped out if they all use a similar style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving accuracy. These types of mounts are useful and practical for rifles which are transferred a lot, to remove the glass from the rifle for protection, or for scopes which are employed in between multiple rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It typically costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle scope can wreck a day on the range and your highly-priced optic by resulting in fogging and producing residue inside of the scope tube. Most optics prevent moisture from going into the scope tube with a series of sealing O-rings which are water resistant. Typically, these water resistant optics can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient wetness avoidance for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still functioning if it goes over the side and you can still rescue the firearm.
Gas Purged Rifle Scope Tubes
Another element of avoiding the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the glass is less affected by temperature level shifts and pressure differences from the outside environment which may possibly allow 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 look for.
