About Scopes
Rifle scopes enable you to exactly aim a rifle at various targets by aligning your eye with the target at range. They do this through magnification by employing a series of lenses within the scope. The scope’s alignment can be dialed in to take into account different ecological factors like wind and elevation increases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will land based upon the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the target. The majority of modern rifle optics have about 11 parts which are found inside and externally on the scope. These scope parts include the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other components. Learn about the eleven parts of optics.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the optimal type of rifle optic depends on what type of shooting you plan to do.
First Focal Plane Glass
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the amount of magnification being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are very little
- Experienced shooters who know their aim point “hold over” as well as “lead” equations for their firearms
- Shooters who do not mind the reticle is bigger and uses up more visual sight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Far away kinds of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots happen within much shorter distances and ranges
- Shooters who want a clearer optic sight picture without room taken up by the bigger FFP reticle
Details on Scope Zoom
The amount of zoom a scope offers is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Optic Info
A single power rifle scope uses a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate considering that it is fixed.
About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom amount in a configuration such as 2-10×32. These numbers imply the magnification of the scope could be adjusted in between 2x and 10x power. This always involves the powers in-between 2 and 10. The power adaptation is achieved using the power ring component of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope power levels and the distances where they can be efficiently used. Always remember that higher power scopes will not be as effective as lower magnification level scope and optics due to the fact that too much magnification can be a detractor. The exact same idea applies to extended distances where the shooter needs increased power to see exactly where to best aim the rifle.
Rifle Glass Lens Finishing
All current rifle optic and scope lenses are coated. Lens covering is a crucial element of a rifle when purchasing high end rifle optics and scope systems.
HD Versus ED Rifle Glass Lens Coatings
Some rifle glass makers also use “HD” or high-def lense coatings that employ different processes, chemical applications, polarizations, and aspects to extract separate color ranges and viewable definition through lenses. This high-def covering is normally used with greater density lens glass which drops light’s ability to refract through the lens glass. Some scope suppliers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration is often obvious over items with hard edges and shapes as light hits the object from specific angles.
Details on Single Covering Versus Multi-Coating
Various scope lenses can also have various finishings applied to them. All lenses usually have at least some type of treatment or covering applied to them before being used in a rifle scope or optic. This is since the lens isn’t just a raw piece of glass. It is part of the finely tuned optic. It needs to have a coating put on it so that it will be efficiently functional in numerous types of environments, degrees of sunlight (full VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers likewise make it a point to specify if their optic lenses are covered or “multi” coated. This suggests the lens has several treatments applied to the surfaces. If a lens gets numerous treatments, it can establish that a maker is taking numerous steps to combat various environmental elements like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This additionally doesn’t always imply the multi-coated lens is better than a single layered lens. Being “better” hinges on the maker’s lens treatment solutions and the quality of glass used in developing the rifle glass.
Glass Lens Hydrophobic Finish
Water on a lens doesn’t assist with maintaining 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 finish.
Rifle Scope Installing Options
Installing solutions for scopes come in a couple of options. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also generally are made in quick release variations which use manual levers which permit rifle shooters to rapidly install and dismount the scopes.
Hex Key Scope Rings
Normal, 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 a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long range accuracy shooting. This type of scope mount is fine for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Glass Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be switched out if they all use a similar design mount. These types of mounts are handy for long guns which are carried a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between several rifles or are situationally focused.
Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can mess up a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. The majority of optics prevent wetness from getting in the scope tube with a series of sealing O-rings which are waterproof. Usually, these optics can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough humidity prevention for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle on a boat and are worried about the scope still working if it goes over the side and you can still rescue the firearm.
About Rifle Glass Tube Gas Purging
Another part of avoiding the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the optic is less altered by temp shifts and pressure distinctions from the outside environment which might potentially enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
