Optic Facts
Rifle scopes permit you to precisely align a rifle at different targets by aligning your eye with the target over a range. They accomplish this through zoom by utilizing a series of lenses inside the scope. The scope’s positioning can be dialed in for consideration of various ecological things like wind and elevation to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based on the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle scopes and optics have around 11 parts which are arranged internally and outside of the optic. These parts include the rifle scope’s body, lenses, windage and elevation dials or turrets, objective focus rings, and other components. Learn about the eleven parts of rifle glass.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the perfect type of rifle glass depends on what type of shooting you plan on doing.
Info About First Focal Plane Optics
First focal plane glass (FFP) feature the reticle in front of the magnifying lens. This induces the reticle to increase in size based upon the amount of zoom being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are very little
- Experienced shooters who recognize their target “hold over” and also “lead” ratios for their firearms
- Shooters who do not mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance types of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots occur within much shorter spaces and ranges
- Shooters who would like a clearer optic picture with less area used up by the bigger FFP reticle
Glass Magnification
The quantity of magnification a scope supplies is identified by the size, thickness, 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 Rifle Scopes
A single power rifle scope or optic uses a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not adjust considering that it is a fixed power scope.
Variable Power Lens Rifle Optics
Variable power rifle scopes can be tweaked between magnified levels. The power change is accomplished by making use of the power ring part of the scope near the back of the scope by the eye bell.
Scope Power and Ranges
Here are some suggested scope power levels and the ranges where they may be effectively used. Bear in mind that higher magnification glass will not be as efficient as lower powered scopes because too much magnification can be a bad thing. The same goes for longer ranges where the shooter needs to have increased power to see exactly where to best aim the rifle.
Info on Rifle Optic Lens Finish
All present day rifle scope and optic lenses are covered. Lens finish is an important element of a shooting system when purchasing high end rifle optics and scope setups.
ED Versus HD Optics
Some glass companies even use “HD” or high-def lense finishes which use different procedures, elements, polarizations, and chemicals to enhance a wide range of colors and viewable target definition through lenses. This high-def coating is often used with more costly, high density glass which lowers light’s ability to refract through the lens glass. Some scope brands use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be obvious over things with well defined outlines as light hits the object from certain angles.
Scope Lens Single Finishing Versus Multi-Coating
Various scope lenses can even have various coverings applied to them. All lenses usually have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many kinds of environments, degrees of light (full light VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope designer and just how much you spent paying for it. Both are indications of the lens quality.
Some scope makers likewise make it a point to specify if their optic lenses are layered or “multi” coated. This suggests the lens has several treatments applied to the surfaces of the glass. If a lens gets several treatments, it can show that a producer is taking numerous steps to fight various environmental factors like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This also does not necessarily indicate the multi-coated lens is much better than a single coated lens. Being “better” depends upon the producer’s lens treatment techniques and the quality of glass used in creating the rifle optic.
Anti-water Lens Covering
Water on an optical lens does not assist with preserving a clear sight picture through a scope whatsoever. Many top of the line and premium scope producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the surface of the Steiner optic lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Scope Mounting Alternatives
Mounting options for scopes are available in a few choices. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also generally are made in quick release versions which use manual levers which enable rifle shooters to rapidly install and remove the scopes.
Hex Key Rifle Scope Rings
Standard, clamp-on type mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These forms of scope mounts use two individual rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance precision shooting. This type of scope mount is excellent for rifle systems which require a resilient, unfailing mount which will not change despite just how much the scope is moved or abuse the rifle takes. These are the design of mounts you should have for a faithful scope system on a long distance scouting or hard target interdiction firearm which will almost never need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on the screws to protect against the hex screw threads from backing out after they are installed safely in position. An example of these rings are the 30mm style from the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle. Several scopes can also be swapped out if they all use a complementary designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while preserving the original sighting settings. These kinds of mounts come in convenient for rifles which are shipped a lot, to take off the glass from the rifle for protection, or for optics which are employed between numerous rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your highly-priced optic by causing fogging and making residue inside of the scope’s tube. Many scopes protect against humidity from getting in the optical tube with a series of sealing O-rings which are water resistant. Usually, these water resistant optics can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of humidity prevention for basic use rifles, unless you anticipate taking your rifle sailing and are worried about the scope still working if it goes over the side and you can still recover the firearm.
Optic Gas Purging
Another element of avoiding the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the optic is less impacted by temp shifts and pressure distinctions from the outdoor environment which might potentially permit 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.
