What You Need to Know About Rifle Optics
Rifle scopes permit you to exactly aim a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnification by utilizing a series of lenses inside the scope. The scope’s positioning can be dialed in to account for various natural things 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 upon the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the intended target. Many contemporary rifle optics have about 11 parts which are arranged internally and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other parts. Learn about the eleven parts of optics.
Rifle Scope Styles
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 lies in relation to the optic’s magnifying adjustments. It actually indicates the reticle is behind or ahead of the magnifying lens of the optic. Looking for the most effective sort of rifle scope depends upon what kind of shooting you plan on undertaking.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are very little
- Experienced shooters who know their target “hold over” as well as “lead” relationships for their firearms
- Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight area than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the magnification lens. This causes the reticle to remain at the very same dimensions in connection with the volume of zoom being used. The end result is that the reticle measurements change based on the zoom applied to shoot over greater ranges considering the markings present distinct increments which differ with the zoom. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These varieties of scopes are useful for:
- Long distance types of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots happen within much shorter ranges and distances
- Shooters who choose a clearer optic picture without space taken up by the bigger FFP reticle
Rifle Optic Zoom
The measure of scope magnification you need on your scope is based on the style of shooting you like to do. Just about every style of rifle scope offers some amount of zoom. The amount of magnification a scope gives is determined by the size, density, and curvatures of the lens glass within the rifle scope. The magnifying level of the scope is the “power” of the scope. This suggests what the shooter is checking out through the scope is magnified times the power element of what can usually be seen by human eyes.
Single Power Lens Scopes
A single power rifle optic will have a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate since it is a fixed power optic.
About Adjustable Power Lens Glass
Variable power rifle scopes can be modified between magnified settings. The power adjustment is accomplished by using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope power settings and the ranges where they can be efficiently used. Always remember that high magnification scopes and optics will not be as efficient as lower powered optics because too much zoom can be a negative thing in certain situations. The same idea applies to longer distances where the shooter needs to have enough power to see where to best aim the rifle at the target.
Details on Lens Finishes
All modern-day rifle scope and optic lenses are covered in special coatings. There are different types and qualities of glass lens finishes. Lens covering can be an important aspect of a rifle when thinking of high-end rifle optics and targeting units. The lenses are among the most significant pieces of the optic because they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses shields the lens surface area and also helps with anti glare from refracted light and color profiles.
HD Versus ED Lenses
Some optic producers also use “HD” or high-def lens finishes that use different processes, elements, rare earth compounds, and polarizations to draw out different colors and viewable target visibility through lenses. This high-definition finish is frequently used with increased density lens glass which lowers light’s chance to refract through the lens glass. Some scope suppliers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be obvious around things with hard edges and shapes as light hits the object from particular angles.
Rifle Optic Lens Single Covering Versus Multi-Coating
Various optic lenses can also have various finishes applied to them. All lenses typically have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It needs to have a finish put on it so that it will be efficiently functional in many types of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing 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 manufacturer and the amount you spent for it. Both are indicators of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are layered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Hydrophobic Lens Finishing
Water on a scope lens doesn’t help with retaining a clear sight picture through an optic in any way. Numerous top of the line or premium scope makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the exterior surfaces of the Steiner glass lens so the H2O particles can not bind to it or develop surface tension. The result is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Choices for Installing Glass on Long Guns
Mounting solutions for scopes can be found in a few choices. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also normally can be found in quick release versions which use throw levers which enable rifle shooters to quickly install and dismount the glass.
Hex Key Rifle Optic Rings
Standard, clamp-on type mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These kinds of scope mounts use double individual rings to support the optic, and are normally made from 7075 T6 billet aluminum which are designed for far away accuracy shooting. This kind of scope mount is very good for rifle systems which need a long lasting, unfailing mount which will not change no matter just how much the scope is moved or abuse the rifle takes. These are the design of mounts you should get for a dedicated scope setup on a far away hunting or competition firearm which will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to keep the hex screw threads from wiggling out after they are installed securely in position. An example of these mounting rings are the 30mm type made by the Vortex Optics company. The set typically costs around $200 USD
Optic Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be swapped out if they all use a similar style mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect nicely to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping precision. These kinds of mounts are useful and handy for shooting platforms which are hauled around a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are utilized in between several rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle optic can ruin a day of shooting and your pricey optic by bringing about fogging and producing residue inside of the scope tube. The majority of scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Optic Gas Purging
Another element of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the optic is less altered by climate changes and pressure variations from the outdoor environment which could potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
