Rifle scopes enable you to specifically aim a rifle at various targets by lining up your eye with the target over a distance. They do this through magnification using a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of different natural elements like wind and elevation to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based on the sight picture you are seeing with the optic as you align the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes and optics have around eleven parts which are located inside and outside of the optic. These parts include the rifle scope’s body, lenses, adjustment dials, focus rings, and other parts. Learn about the eleven parts of glass.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane a scope has establishes where the reticle or crosshair is located relative to the scopes zoom. It simply indicates the reticle is behind or before the magnifying lens of the optic. Choosing the most beneficial type of rifle optic is based on what sort of shooting you plan on undertaking.
First Focal Plane Glass Info
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This causes the reticle to increase in size based on the amount of zoom being used. The result is that the reticle measurements are the same at the enhanced range as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are marginal
- Experienced shooters who have an idea for their aim point “hold over” and “lead” equations for their long guns
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the magnifying lens. This causes the reticle to stay at the very same size relative to the volume of zoom being used. The end result is that the reticle measurements shift based upon the magnification employed to shoot over longer distances because the reticle markings represent various increments which can vary with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular sorts of optics are useful for:
- Long distance forms of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who like a clearer optic sight picture without room used up by the larger sized FFP reticle
Zoom for Rifle Scopes
The amount of magnification a scope supplies is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Optics
A single power rifle scope uses a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not adjust since it is a set power scope.
Info on Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification power levels. These types of scopes will note the zoom degree in a format like 2-10×32. These numbers mean the zoom of the scope could be changed between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power modification is achieved by making use of the power ring component of the scope near the rear of the scope by the eye bell piece.
Power Levels and Range Correlations
Here are some recommended scope powers and the distances where they can be successfully used. High power scopes will not be as effective as lower powered glass since too much magnification can be a negative aspect depending on your shooting distance. The same idea relates to longer ranges where the shooter needs increased power to see precisely where to best aim the rifle.
Rifle Glass Lens Finishing
All modern rifle scope and optic lenses are layered. There are various types and qualities of glass lens coatings. When considering high end rifle optical systems, Lens covering can be a significant element of defining the capability of the rifle. The glass lenses are among the most crucial components of the optic given that they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses protects the lens surface area as well as helps with anti glare from excess sunshine and color visibility.
Info on Glass Lens Coatings – HD Versus ED
Some rifle scope makers additionally use “HD” or high-definition lense finishings that apply different procedures, rare earth compounds, aspects, and polarizations to extract different colors and viewable definition through lenses. This high-definition coating is normally used with increased density glass which lowers light’s ability to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration is often noticeable over items with hard shapes as light hits the object from various angles.
Optic Lens Single Coating Versus Multi-Coating
Different optic lenses can likewise have various finishes used to them. All lenses generally have at least some type of treatment or finish applied to them before being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
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 maker’s lens treatment technology and the quality of materials used in building the rifle scope.
Details on Anti-water Finishing
Water on a lens doesn’t assist with keeping 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 hydrophobic or hydrophilic covering.
Rifle Scope Installing Alternatives
Mounting solutions for scopes are available in a few options. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These various types of mounts also usually can be found in quick release variations which use throw levers which enable rifle shooters to quickly install and remove the glass.
Hex Key Rifle Scope Rings
Normal, clamp style 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 a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope install is wonderful for rifles which require a long lasting, rock solid mount 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 before reattaching it to a different rifle. Multiple scopes can even be switched out if they all use a compatible design mount. These types of mounts are handy for rifle platforms which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between multiple rifles.
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle optic can ruin a day of shooting and your highly-priced optic by triggering fogging and creating residue within the scope tube. A lot of scopes protect against wetness from getting in the optical tube with a series of sealing O-rings which are waterproof. Typically, these water-resistant optics can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient wetness prevention for standard use rifles for hunting and sporting purposes, unless you anticipate taking your rifle boating and are concerned about the scope still performing if it goes over the side and you can still salvage the gun.
Info on Rifle Optic Tube Gas Purging
Another component of avoiding the buildup of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the scope is less altered by climate shifts and pressure distinctions from the outdoor environment which could possibly 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 seek out.
