Rifle Optic Information
Rifle scopes allow you to exactly align a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through zoom by using a set of lenses within the scope. The scope’s alignment can be adapted to take into account different natural factors like wind speed and elevation increases to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the target. A lot of contemporary rifle optics have around eleven parts which are found inside and on the exterior of the scope. These parts include the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other components. See all eleven parts of an optic.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane a scope has establishes where the reticle or crosshair is located relative to the optic’s magnifying adjustments. It literally implies the reticle is situated behind or in front of the magnifying lens of the optic. Selecting the most suitable kind of rifle glass is based upon what style of shooting you plan on doing.
Info About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who understand their target “hold over” and also “lead” relationships for their long guns
- Shooters who do not mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Second Focal Plane Optic Facts
Second focal plane glass (SFP) include the reticle behind the magnification lens. This induces the reticle to stay at the same overall size relative to the amount of zoom being used. The effect is that the reticle dimensions evolve based on the zoom applied to shoot over greater ranges considering that the reticle markings present various increments which fluctuate with the magnification level. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These varieties of optics work for:
- Long distance forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots occur within much shorter ranges and distances
- Shooters who want a clearer optic picture with less area taken up by the larger size FFP reticle
Zoom for Rifle Glass
The quantity of zoom a scope supplies is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Scope Info
A single power rifle optic will have a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not fluctuate considering that it is a fixed power optic.
Variable Power Lens Rifle Glass Details
Variable power rifle scopes have adjustable power. It will list the zoom degree in a configuration like 2-10×32. These numbers imply the zoom of the scope could be adjusted between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power shift is accomplished by operating the power ring part of the scope near the back of the scope by the eye bell piece.
The Power Level and Range of Rifle Scopes
Here are some advised scope power levels and the ranges where they could be successfully used. High power scopes will not be as effective as lower magnification scopes considering too much zoom can be a bad thing. The exact same concept relates to extended ranges where the shooter needs to have sufficient power to see precisely where to best aim the rifle at the target.
Rifle Glass Lens Finish
All contemporary rifle optic and scope lenses are covered in special coatings. There are various types and qualities of coverings. Lens coating is a crucial element of a rifle when considering high-end rifle optics and targeting equipment. The glass lenses are among the most significant pieces of the scope due to the fact that they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses protects the lens surface and even helps with anti glare capabilities from excess daylight and color perception.
HD Versus ED Scope Lens Coatings
Some rifle glass suppliers even use “HD” or high-def lens coatings that apply various processes, aspects, chemicals, and polarizations to enhance a wide range of colors and viewable target definition through the lens. This HD coating is normally used with higher density glass which decreases light’s opportunity to refract by means of the lens glass. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how certain colors are represented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be visible around things with hard edges and outlines as light hits the object from specific angles.
Single Rifle Glass Lens Coating Versus Multi-Coating
Different optic lenses can also have various finishes applied to them. All lenses generally have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It must have a finish placed on it so that it will be optimally usable in numerous kinds of environments, degrees of light (full light VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while reducing 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 on the scope producer and how much you paid for it.
Some scope makers likewise make it a point to define if their optic lenses are layered or “multi” coated. This indicates the lens has numerous treatments applied to the surfaces. If a lens gets multiple treatments, it can prove that a company is taking numerous steps to combat different natural factors like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This additionally doesn’t necessarily mean the multi-coated lens is better than a single layered lens. Being “better” depends upon the producer’s lens treatment techniques and the quality of materials used in constructing the rifle glass.
Hydrophobic Lens Finishes
Water on an optic’s lens does not assist with retaining a clear sight picture through an optic in any way. Lots of top of the line or premium scope producers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the surface area of the Steiner glass lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to maintain a clear, water free sight picture.
Options for Installing Rifle Scopes on Long Guns
Installing solutions for scopes come in a couple of options. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually are made in quick release variations which use manual levers which allow rifle shooters to rapidly mount and remove the scope.
Optic Mounts with Hex Key Rings
Basic, clamp-on style mounting optic rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use a pair of individual rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are developed for far away precision shooting. This kind of scope mount is effective for rifles which need to have a long lasting, rock solid mount which will not change no matter 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 long distance scouting or hard target interdiction rifle that will pretty much never need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on screws to stop the hex screws from wiggling out after they are installed tightly in position. An example of these rings are the 30mm style made by the Vortex Optics company. The set usually costs around $200 USD
Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and connect it to a different rifle. Numerous scopes can even be swapped 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 in between multiple rifles.
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can spoil a day on the range and your expensive optic by inducing fogging and creating residue inside of the scope tube. A lot of optics protect against moisture from entering the optical tube with a series of sealing O-rings which are waterproof. Normally, these water resistant optics can be submerged 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 for hunting and sporting purposes, unless you plan on taking your rifle boating and are concerned about the scope still performing if it goes over the side and you can still recover the firearm.
Info on Rifle Glass Tube Gas Purging
Another element of avoiding the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the scope is less affected by condition alterations and pressure variations from the outdoor environment which could potentially 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 look for.
