Optic Information
Rifle scopes permit 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 using a set of lenses within the scope. The scope’s alignment can be adapted to account for numerous ecological aspects like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will land based upon the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the target. Most modern rifle optics have around 11 parts which are located internally and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other components. Learn about the eleven parts of rifle optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The sort of focal plane a scope has establishes where the reticle or crosshair is located relative to the scopes magnifying adjustments. It simply indicates the reticle is located behind or in front of the magnification lens of the optic. Picking the most reliable sort of rifle scope is based on what variety of shooting or hunting you intend on undertaking.
First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who recognize their aim point “hold over” as well as “lead” correlations for their long guns
- Shooters who do not mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Second Focal Plane Scope Details
Second focal plane optics (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Far away styles of shooting where shooters have more time to make ballistic computations
- Shooting where most shots take place within much shorter ranges and proximities
- Shooters who like a clearer optic sight picture with less room used up by the enlarged FFP reticle
Rifle Optic Magnification
The quantity of zoom a scope provides is figured out 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 Single Power Lens Optics
A single power rifle optic will have a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not change considering that it is a fixed power optic.
Variable Power Lens Glass
Variable power rifle scopes have adjustable power. It will list the zoom degree in a format like 2-10×32. These numbers imply the magnification of the scope could be adjusted between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power adaptation is accomplished by employing the power ring part of the scope near the back of the scope by the eye bell piece.
Power Levels and Range
Here are some advised scope powers and the distances where they can be effectively used. Bear in mind that high magnification optics and scopes will not be as effective as lower magnification level optics and scopes because too much magnification can be a bad thing. The same relates to longer ranges where the shooter needs sufficient power to see exactly where to best aim the rifle at the target.
Details on Lens Coatings
All state-of-the-art rifle optic and scope lenses are covered. Lens finish is an essential element of a rifle’s setup when thinking about high end rifle optics and scope equipment.
About Rifle Glass Lens Coatings – HD Versus ED
Some optic makers additionally use “HD” or high-def lense finishes which make the most of various processes, rare earth compounds, components, and polarizations to enhance a wide range of color ranges and viewable target definition through lenses. This high-def covering is often used with higher density lens glass which reduces light’s ability to refract by means of the lens glass. Some scope producers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how colors are represented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around objects with well defined outlines as light hits the item from various angles.
Single Coating Versus Multi-Coating for Rifle Scopes
Various optic lenses can even have different coverings applied to them. All lenses typically have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally functional in many types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is typically 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 covered lens depends upon the scope designer and how much you spent paying for it. Both the make and cost are indications of the lens quality.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” covered. This indicates the lens has several treatments applied to the surfaces. If a lens receives several treatments, it can prove that a manufacturer is taking numerous steps to combat different natural aspects like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This additionally does not always mean the multi-coated lens is much better than a single layered lens. Being “better” hinges on the producer’s lens treatment technology and the quality of materials used in building the rifle glass.
Hydrophobic Lens Finishing
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Lots of top of the line and military grade scope companies will coat their lenses with a hydrophobic or hydrophilic finish.
Options for Installing Optics on Long Guns
Mounting approaches for scopes are available in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release variations which use throw levers which permit rifle shooters to quickly mount and remove the optics.
Hex Key Glass Ring Mounts
Normal, clamp design 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 often made from 7075 T6 billet aluminum which is designed for long range precision shooting. This type of scope install is perfect for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle. A wide range of scopes can also be swapped out if they all use a similar designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping the original sighting settings. These types of mounts come in beneficial for rifles which are moved a lot, to take off the glass from the rifle for protection, or for optics which are used between multiple rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle scope can wreck a day on the range and your costly optic by resulting in fogging and producing residue inside of the scope tube. The majority of optics protect against moisture from going into the scope tube with a series of sealing O-rings which are water resistant. Normally, these optics can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture avoidance for standard use rifles, unless you plan on taking your rifle sailing and are worried about the scope still performing if it is submerged in water and you can still rescue the rifle.
Gas Purged Rifle Optic Tubes
Another component of avoiding the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is currently occupied by the gas, the scope is less altered by temp shifts and pressure variations from the outdoor environment which could potentially permit 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 seek out.
