Rifle scopes allow you to exactly align a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnification by employing a set of lenses within the scope. The scope’s alignment can be adjusted to account for varied environmental factors like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes have about 11 parts which are arranged within and outside of the optic. These scope parts consist of the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other elements. See all eleven parts of an optic.
About Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the optimal type of rifle optic is based on what type of shooting you plan to do.
Info on First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who understand their target “hold over” and also “lead” relationships for their rifles
- Shooters who do not mind the reticle is enlarged and takes up 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 same size in relation to the volume of zoom being used. The final result is that the reticle dimensions adapt based on the magnification employed to shoot over lengthier distances considering that the markings represent various increments which change with the magnification level. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement. These sorts of optics work for:
- Long distance forms of shooting where shooters have additional time to make ballistic computations
- Shooting where most of the shots occur within shorter proximities and ranges
- Shooters who like a clearer optic picture without room used up by the bigger FFP reticle
The quantity of scope magnification you require is based on the type of shooting you would like to do. Almost every style of rifle scope gives some level of magnification. The volume of magnification a scope gives is determined by the size, density, and curvatures of the lenses within the rifle optic. The magnification level of the optic is the “power” of the scope. This signifies what the shooter is observing through the scope is amplified times the power aspect of what can normally be seen by human eyes.
Info About Single Power Lens Glass
A single power rifle scope or optic will have 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 zoom of this kind of scope can not adjust given that it is fixed.
Adjustable Power Lens Scope Details
Variable power rifle scopes use variable power levels. The power modification is handled by the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range of Rifle Optics
Here are some advised scope power levels and the ranges where they can be successfully used. Keep in mind that high power scopes and optics will not be as practical as lower magnification level glass due to the fact that increased zoom can be a negative thing in certain situations. The exact same concept relates to extended distances where the shooter needs adequate power to see exactly where to properly aim the rifle.
Lens Finish for Glass
All present day rifle glass lenses are covered. Lens covering is a crucial aspect of a shooting system when looking at high end rifle optics and scope systems.
HD Versus ED Rifle Scope Lens Coatings
Some scope producers likewise use “HD” or high-definition lens coatings which use different techniques, polarizations, chemicals, and components to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finish Versus Multi-Coating
Various optic lenses can likewise have various finishes used to them. All lenses normally have at least some type of treatment or covering used to them before being used in a rifle scope or optic.
This lens treatment can safeguard 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 covered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” coated. This suggests the lens has multiple treatments applied to the surfaces of the glass. If a lens receives several treatments, it can indicate that a manufacturer is taking numerous steps to fight different environmental factors like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This also doesn’t always indicate the multi-coated lens is much better than a single covered lens. Being “better” hinges on the maker’s lens treatment innovation and the quality of components used in constructing the rifle scope.
Details on Hydrophobic Coating
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Numerous top of the line and military grade optic makers will coat their lenses with a hydrophilic or hydrophobic covering which is water repellent.
Alternatives for Mounting Optics on Long Guns
Installing options for scopes can be found in a few choices. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also usually come in quick release versions which use throw levers which permit rifle shooters to quickly mount and dismount the optics.
Hex Key Rifle Glass Ring Mounts
Normal, clamp style 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 range accuracy shooting. This type of scope mount is great for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be swapped out if they all use a complementary designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining the original sighting settings. These kinds of mounts come in handy for shooting platforms which are hauled around a lot, to remove the glass from the rifle for protection, or for scopes which are used between a number of rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can wreck a day on the range and your pricey optic by inducing fogging and generating residue inside of the scope’s tube. Most optics protect against humidity from entering the scope tube with a system of sealing O-rings which are waterproof. Normally, these scopes can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of wetness prevention for conventional use rifles for hunting and sporting purposes, unless you anticipate taking your rifle sailing and are concerned about the optic still working if it is submerged in water and you can still retrieve the firearm.
About Rifle Optic Tube Gas Purging
Another part of preventing the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the optic is less affected by climate shifts and pressure variations from the external environment which might potentially allow water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
