Rifle Optic Facts
Rifle scopes permit you to precisely aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnification using a series of lenses inside the scope. The scope’s alignment can be adjusted for the consideration of various ecological considerations like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the intended target. Many contemporary rifle optics have around 11 parts which are located within and outside of the optic. These scope parts consist of the rifle scope’s body, lenses, modification dials, objective focus rings, and other components. See all eleven parts of a rifle optical system.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the optimal type of rifle scope is based around what type of shooting you plan on doing.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” correlations for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual sight room than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle to the rear of the magnification lens. This triggers the reticle to remain at the same size in connection with the amount of magnification being used. The result is that the reticle dimensions shift based on the magnification used to shoot over greater distances considering the markings represent different increments which fluctuate with the zoom level. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement. These varieties of glass work for:
- Long distance types of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots occur within much shorter ranges and distances
- Shooters who desire a clearer optic picture with less space taken up by the bigger FFP reticle
About Optic Magnification
The amount of magnification a scope offers is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
About Single Power Lens Rifle Scopes
A single power rifle optic and scope comes with a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not fluctuate because it is set from the factory.
Variable Power Lens Scopes
Variable power rifle scopes can be changed between magnification increments. It will list the magnification level in a configuration like 2-10×32. These numbers imply the magnification of the scope can be set between 2x and 10x power. This always includes the powers in-between 2 and 10. The power shift is achieved by applying the power ring part of the scope near the back of the scope by the eye bell piece.
The Power Level and Range Correlation of Rifle Optics
Here are some advised scope power levels and the distances where they can be effectively used. Keep in mind that high magnification scopes and optics will not be as efficient as lower magnification level glass because excessive magnification can be a negative thing in certain situations. The same concept applies to extended ranges where the shooter needs to have adequate power to see where to properly aim the rifle at the target.
Info on Lens Covering
All modern-day rifle scope and optic lenses are layered. There are various types and qualities of lens finishes. Lens finish can be an important aspect of a rifle when contemplating high-end rifle optics and targeting equipment. The lenses are among the most critical parts of the optic considering they are what your eye sees through while sighting a rifle in on the point of impact. The covering on the lenses safeguards the lens surface and also improves anti glare from refracted daylight and color exposure.
HD Versus ED Lenses
Some scope producers likewise use “HD” or high-definition lens coatings which use various methods, elements, chemicals, and polarizations to draw out separate colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Scope Lens Single Finishing Versus Multi-Coating
Various optic lenses can even have various coatings applied to them. All lenses usually have at least some kind 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 becomes part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently functional in lots of kinds of environments, degrees of light (full VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope company and how much money you paid for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope producers likewise make it a point to specify if their optic lenses are layered or “multi” covered. This indicates the lens has had multiple treatments applied to the surfaces. If a lens gets multiple treatments, it can prove that a maker is taking multiple steps to fight various environmental factors like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This additionally does not necessarily imply the multi-coated lens will perform much better than a single covered lens. Being “much better” hinges on the producer’s lens treatment solutions and the quality of glass used in building the rifle glass.
Info on Hydrophobic Covering
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic coating.
Alternatives for Mounting Optics on Firearms
Installing solutions for scopes come in a few choices. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also generally come in quick release variations which use throw levers which enable rifle operators to rapidly mount and dismount the glass.
Rifle Glass Mounts with Hex Key Rings
Basic, clamp style mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mount rails on the tops of rifles. These forms of scope mounts use two separate rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are made for long distance accuracy shooting. This kind of scope mount is effective for rifles which need to have a long lasting, rock solid mount which will not move regardless of just how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a dedicated optics system on a long distance hunting or competitors firearm that will hardly ever need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to prevent the hex screws from backing out after they are mounted safely in place. An example of these rings are the 30mm type from Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle. Multiple scopes can also be switched out if they all use a complementary style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining the original sighting settings. These kinds of mounts come in convenient for rifles which are moved around a lot, to take off the scope glass from the rifle for protection, or for sight systems which are employed in between a number of rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
What to Know About Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can wreck a day on the range and your pricey optic by causing fogging and generating residue within the scope tube. Many optics prevent humidity from going into the scope tube with a series of sealing O-rings which are waterproof. Generally, these scopes can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture content avoidance for conventional use rifles, unless you intend on taking your rifle sailing and are worried about the scope still working if it is submerged in water and you can still find the rifle.
Gas Purged Rifle Glass Tubes
Another component of avoiding the buildup of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the optic is less affected by condition shifts and pressure variations from the outdoor 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 good rifle scope to look for.
