Rifle Optic Facts
Rifle scopes allow you to precisely align a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through zoom by making use of a set of lenses inside the scope. The scope’s positioning can be adjusted to account for numerous natural things like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based upon the sight picture you are seeing through the optic as you line up the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle optics have around eleven parts which are arranged inside and externally on the scope. These scope parts include the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other parts. Learn about the eleven parts of rifle glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the optimal type of rifle optic depends on what type of shooting you plan to do.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where estimations are very little
- Experienced shooters who have an idea for their target “hold over” and “lead” equations for their rifles
- Shooters who don’t mind the reticle is bigger and uses up more visual sight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle 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 calculations
- Shooting where most of the shots take place within much shorter distances and ranges
- Shooters who desire a clearer optic picture without space taken up by the larger size FFP reticle
Zoom for Rifle Optics
The amount of zoom a scope supplies is determined by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Rifle Scope Facts
A single power rifle scope or optic will have a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not adjust since it is fixed.
About Variable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification amount in a format such as 2-10×32. These numbers imply the zoom of the scope could be changed between 2x and 10x power. This additionally utilizes the power levels in-between 2 and 10. The power adaptation is accomplished by applying the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some suggested scope power levels and the distances where they could be effectively used. Highly magnified rifle scope glass will not be as beneficial as lower magnification scopes considering too much magnification can be a negative aspect depending on your shooting distance. The same idea relates to extended distances where the shooter needs to have increased power to see where to properly aim the rifle.
Lens Finish for Optics
All modern rifle scope and optic lenses are layered. There are various types and qualities of finishings. When researching high end rifle optics and scope systems, Lens covering can be an essential aspect of defining the capability of the rifle. The lenses are among the most key pieces of the optic considering that they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses safeguards the lens surface as well as improves anti glare from refracted daylight and color perception.
Info on Glass Lens Coatings – HD Versus ED
Some rifle glass companies will also use “HD” or high-definition lense finishings which employ different processes, polarizations, components, and chemicals to extract a wide range of colors and viewable definition through lenses. This HD finish is normally used with more costly high density glass which reduces light’s ability to refract through the lens glass. Some scope vendors use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration may be noticeable over items with defined outlines as light hits the object from particular angles.
Single Scope Lens Coating Versus Multi-Coating
Different optic lenses can likewise have different coverings applied to them. All lenses normally have at least some type of treatment or coating used to them before being used in a rifle scope or optic.
This lens treatment can safeguard 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 layered lens depends on the scope maker and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” coated. This indicates the lens has several treatments applied to the surfaces. If a lens receives numerous treatments, it can establish that a maker is taking multiple actions to fight different environmental factors like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This additionally doesn’t necessarily mean the multi-coated lens will perform much better than a single covered lens. Being “better” hinges on the manufacturer’s lens treatment techniques and the quality of components used in developing the rifle optic.
What to Know About Anti-water Finish
Water on an optic’s lens doesn’t help with preserving a clear sight picture through an optic whatsoever. Numerous top of the line or high-end scope makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It deals with the surface of the Steiner scope lens so the water particles can not bind to it or create surface tension. The result is that the water beads roll off of the scope to keep a clear, water free sight picture.
Alternatives for Mounting Glass on Firearms
Mounting solutions for scopes can be found in a few choices. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release variations which use toss levers which enable rifle operators to rapidly mount and remove the scopes.
Hex Key Rifle Scope Rings
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 separate rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long range accuracy shooting. This type of scope install is perfect for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Optic Mounting Solutions 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 before reattaching it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible design mount. These types of mounts come in handy for rifle platforms which are carried a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used in between multiple rifles or are situationally focused.
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle scope can mess up a day on the range and your highly-priced optic by triggering fogging and generating residue inside of the scope tube. The majority of optics protect against humidity from entering the scope tube with a system of sealing O-rings which are water resistant. Usually, these water-resistant scopes can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient moisture content prevention for standard use rifles, unless you plan on taking your rifle aboard watercrafts and are concerned about the scope still performing if it is submerged in water and you can still recover the gun.
Optic Gas Purging
Another part of preventing the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the glass is less influenced by climate changes and pressure variations from the outdoor environment which might possibly 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.
