All About Rifle Optics
Rifle scopes enable you to precisely align a rifle at various targets by lining up your eye with the target over a range. They do this through magnification by utilizing a series of lenses within the scope. The scope’s positioning can be adapted for consideration of numerous environmental considerations like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the intended target. Most modern-day rifle scopes have around 11 parts which are arranged within and on the exterior of the scope body. These parts include the rifle scope’s body, lenses, modification dials, focus rings, and other parts. Learn about the eleven parts of rifle glass.
About Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the optimal type of rifle scope depends on what type of shooting you plan to do.
Info on First Focal Plane Glass
First focal plane scopes (FFP) include the reticle ahead of the magnifying lens. This triggers the reticle to increase in size based upon the extent of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non amplified range. For example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at one hundred yards using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are small
- Experienced shooters who recognize their target “hold over” and “lead” relationships for their firearm
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight area than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) include 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 reticle measurement.
- Far away forms of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots happen within shorter proximities and ranges
- Shooters who choose a clearer optic picture without room used up by the larger sized FFP reticle
Ins and Outs of Rifle Glass Zoom
The level of scope magnification you need depends on the form of shooting you would like to do. Virtually every style of rifle glass gives some amount of zoom. The quantity of magnification a scope gives is identified by the diameter, thickness, and curvatures of the lens glass within the rifle optic. The zoom of the scope is the “power” of the glass. This indicates what the shooter is aiming at through the scope is magnified times the power element of what can usually be seen by human eyes.
Single Power Lens Optics
A single power rifle scope and optic comes with a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not change given that it is a fixed power optic.
Info About Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be adjusted between magnification power levels. It will list the magnification level in a configuration like 2-10×32. These numbers suggest the magnification of the scope can be adjusted in between 2x and 10x power. This also incorporates the power levels in-between 2 and 10. The power shift is accomplished by applying the power ring component of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Rifle Scopes
Here are some suggested scope powers and the distances where they could be effectively used. High power optics will not be as efficient as lower powered scopes considering that too much magnification can be a bad thing. The same idea goes for extended ranges where the shooter needs increased power to see exactly where to best aim the rifle.
About Rifle Scope Lens Coating
All modern rifle optic lenses are covered in special coatings. There are different types and qualities of glass lens coverings. When shopping for luxury rifle targeting systems, Lens finish can be a vital element of defining the rifle’s capability. The glass lenses are among the most vital parts of the glass because they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses safeguards the lens surface and even helps with anti glare from refracted sunrays and color discernibility.
Details on Rifle Optic Lens Coatings – HD Versus ED
Some scope manufacturers also use “HD” or high-definition lens coatings which use different techniques, chemicals, aspects, and polarizations to draw out a wide range of colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Glass Lens Finishing Versus Multi-Coating
Various optic lenses can even have various finishes applied to them. All lenses generally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the finely tuned optic. It needs to have a covering applied to it so that the lens will be efficiently usable in many types of environments, degrees of light (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less advantageous 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 similarly 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.
Hydrophobic Rifle Optic Lens Finishing
Water on a scope’s lens doesn’t support maintaining a clear sight picture through a scope whatsoever. Numerous top of the line and high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the surface of the Steiner glass lens so the H2O molecules can not bind to it or produce surface tension. The result is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Rifle Scope Mounting Options
Installing options for scopes come in a few options. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also normally come in quick release versions which use toss levers which allow rifle shooters to rapidly install and dismount the glass.
Optic Mounting Solutions with Hex Key Rings
Standard, 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 two 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 fine for rifles which need a long lasting, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and attach it to a different rifle. Multiple scopes can even be swapped out if they all use a compatible design mount. These types of mounts are convenient for rifle platforms which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between several rifles.
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by causing fogging and producing residue inside of the scope tube. The majority of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Rifle Optic Gas Purging
Another element of avoiding the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the scope is less influenced by temperature shifts and pressure variations from the external environment which might potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
