Facts About Glass
Rifle scopes allow you to specifically aim a rifle at various targets by aligning your eye with the target at range. They do this through magnifying the target by making use of a series of lenses within the scope. The scope’s alignment can be adjusted to take into account separate environmental considerations like wind speed and elevation to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle scopes have about 11 parts which are arranged internally and externally on the scope body. These scope parts include the rifle scope’s body, lenses, windage and elevation 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” type of scopes. Picking the best type of rifle optic is based on what type of shooting you plan on doing.
Info About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who understand their target “hold over” and “lead” ratios for their firearm
- Shooters who do not mind the reticle is enlarged and requires more visual sight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle behind the magnification lens. This causes the reticle to stay at the exact same overall size in relation to the level of magnification being used. The end result is that the reticle dimensions alter based upon the zoom employed to shoot over longer ranges considering the reticle measurements present distinct increments which differ with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement. These particular sorts of glass are convenient for:
- Long distance forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots take place within much shorter ranges and spaces
- Shooters who desire a clearer optic sight picture without room taken up by the larger size FFP reticle
Zoom for Scopes
The quantity of scope magnification you need depends on the type of shooting you plan to do. Pretty much every type of rifle optic supplies some degree of magnification. The amount of zoom a scope delivers is established by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification level of the scope is the “power” of the glass. This indicates what the shooter is aiming at through the scope is magnified times the power element of what can typically be seen by human eyes.
Single Power Lens Rifle Optic Info
A single power rifle optic will have a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not fluctuate since it is a set power scope.
Variable Power Lens Scope Info
Variable power rifle scopes can be changed between magnification increments. These types of scopes will list the magnification level in a configuration like 2-10×32. These numbers suggest the zoom of the scope could be set in between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power modification is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell.
Scope Power and Ranges
Here are some recommended scope power settings and the distances where they may be efficiently used. High power scopes will not be as effective as lower magnification level glass considering that too much magnification can be a negative aspect depending on your shooting distance. The very same idea applies to longer ranges where the shooter needs to have enough power to see exactly where to properly aim the rifle.
Glass Lens Covering
All state-of-the-art rifle glass lenses are coated. Lens coating can be a significant aspect of a shooting system when looking into high end rifle optics and scope systems.
About Glass Lens Coatings – HD Versus ED
Some scope makers likewise use “HD” or high-definition lens coverings which use different processes, components, polarizations, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finish Versus Multi-Coating
Different optic lenses can also have different coatings used to them. All lenses typically have at least some type of treatment or finishing used to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing glare and other less useful 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 paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” coated. This indicates the lens has several treatments applied to them. If a lens gets multiple treatments, it can prove that a manufacturer is taking multiple actions to fight different environmental elements like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This also does not necessarily imply the multi-coated lens will perform better than a single coated lens. Being “better” depends on the producer’s lens treatment innovation and the quality of materials used in creating the rifle optic.
Anti-water Lens Coatings
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Many top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Choices for Installing Rifle Scopes on Long Guns
Installing approaches for scopes are available in a couple of 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 normally can be found in quick release variations which use toss levers which permit rifle shooters to rapidly mount and dismount the scopes.
Rifle Scope Mounts with Hex Key Rings
Standard, 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 made from 7075 T6 billet aluminum which is created for long range accuracy shooting. This type of scope install is great for rifles which require a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Glass Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, a number of scopes can often be switched out. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining accuracy. These types of mounts come in convenient for shooting platforms which are moved around a lot, to remove the glass from the rifle for protection, or for aiming systems which are chosen for use between multiple rifles. An example of this mount style is the 30mm mount from Vortex Optics. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle glass can spoil a day of shooting and your expensive optic by causing fogging and making residue inside of the scope tube. A lot of optics protect against moisture from entering the optical tube with a series of sealing O-rings which are water resistant. Typically, these water-resistant scopes can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture avoidance for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle on boats and are worried about the optic still functioning if it goes overboard and you can still salvage the gun.
Gas Purged Optic Tubes
Another part of preventing the buildup of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the optic is less impacted by temperature level shifts and pressure variations from the external environment which might 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.
