Rifle scopes permit you to exactly align a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by making use of a series of lenses inside the scope. The scope’s alignment can be adapted for consideration of varied natural factors like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the target. The majority of modern-day rifle scopes have about eleven parts which are found inside and externally on the optic. These optic pieces include the rifle scope’s body, lenses, adjustment turrets, focus rings, and other elements. See all eleven parts of a scope.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The type of focal plane a scope has identifies where the reticle or crosshair is located in connection with the scopes zoom. It literally indicates the reticle is situated behind or ahead of the magnification lens of the optic. Deciding upon the most reliable form of rifle glass is based upon what form of hunting or shooting you plan on doing.
Info About 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 types of shooting
- Shooting situations where estimations are minimal
- Experienced shooters who understand their target “hold over” and “lead” correlations for their firearm
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight room than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots occur within much shorter distances and ranges
- Shooters who prefer a clearer optic picture with less room used up by the larger size FFP reticle
Zoom for Glass
The extent of scope zoom you need on your glass depends upon the type of shooting you choose to do. Just about every style of rifle optic supplies some amount of magnification. The volume of magnification a scope provides is identified by the size, thickness, and curves of the lens glass within the rifle optic. The zoom of the optic is the “power” of the opic. This suggests what the shooter is checking out through the scope is amplified times the power factor of what can generally be seen by human eyes.
Fixed Single Power Lens Rifle Optics
A single power rifle optic uses a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate because it is fixed.
Adjustable Power Lens Rifle Glass Info
Variable power rifle scopes can be tweaked between magnified settings. The power adjustment is accomplished by the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Glass Power and Ranges
Here are some recommended scope power settings and the distances where they may be efficiently used. Keep in mind that high power glass will not be as practical as lower magnification level scopes because too much magnification can be a bad thing. The same idea relates to extended distances where the shooter needs to have enough power to see where to best aim the rifle at the target.
Details on Lens Coatings
All modern rifle scope lenses are covered in special coatings. There are different types and qualities of lens coatings. When considering luxury rifle optical devices, Lens finishing can be a vital aspect of a rifle. The glass lenses are among the most significant parts of the scope since they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses shields the lens exterior as well as helps with anti glare from excess natural light and color discernibility.
HD Versus ED Lenses
Some scope brands likewise use “HD” or high-definition lens finishings which use different processes, polarizations, chemicals, and elements to draw out a wide range of colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Glass
Various optic lenses can likewise have different coatings applied to them. All lenses usually have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while lowering 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 the amount you spent paying for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of products used in building the rifle scope.
Anti-water Scope Lens Finish
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic finishing.
Options for Installing Glass on Long Guns
Mounting approaches for scopes can be found in a couple of options. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also typically are made in quick release versions which use throw levers which allow rifle operators to quickly mount and remove the scopes.
Glass Mounts with Hex Key Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope mount is wonderful for rifles which require a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Glass Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle. If they all use a comparable style mount, a number of scopes can often be switched in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining the original sighting settings. These types of mounts are useful and convenient for rifles which are moved a lot, to remove the optic from the rifle for protection, or for scopes which are utilized between several rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle scope can wreck a day of shooting and your highly-priced optic by resulting in fogging and making residue inside of the scope tube. Many scopes prevent humidity from entering the scope tube with a series of sealing O-rings which are waterproof. Generally, these water-resistant optics can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture prevention for common use rifles for hunting and sporting purposes, unless you anticipate taking your rifle aboard watercrafts and are concerned about the optic still working if it is submerged in water and you can still find the gun.
Rifle Optic Gas Purging
Another component of avoiding the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the optic is less altered by temperature level changes and pressure variations from the outdoor environment which may potentially permit 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.
