About Rifle Optics
Rifle scopes allow you to precisely align a rifle at various targets by lining up your eye with the target over a distance. They do this through magnification by using a set of lenses within the scope. The scope’s alignment can be adjusted for consideration of different environmental things like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based on the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the target. A lot of modern rifle optics have about eleven parts which are arranged internally and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, modification dials, objective focus rings, and other elements. See all eleven parts of an optic.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane an optic has establishes where the reticle or crosshair lies relative to the optic’s magnification. It simply indicates the reticle is situated behind or before the magnification lens of the scope. Picking the best type of rifle glass is dependent on what variety of shooting or hunting you intend on undertaking.
Info About First Focal Plane Glass
First focal plane glass (FFP) include the reticle before the zoom lens. This causes the reticle to increase in size based on the extent of magnification being used. The outcome is that the reticle measurements are the same at the enhanced distance as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at one hundred yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are marginal
- Experienced shooters who know their aim point “hold over” and also “lead” correlations for their rifles
- Shooters who don’t mind the reticle is bigger and occupies more visual sight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots happen within shorter ranges and spaces
- Shooters who select a clearer optic sight picture without space used up by the larger sized FFP reticle
Zoom for Optics
The quantity of zoom a scope provides is identified by the size, density, 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 Optic Facts
A single power rifle scope will have a magnification number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not change considering that it is a fixed power optic.
About Variable Power Lens Optics
Variable power rifle scopes can be tweaked between magnified settings. The power adjustment is performed by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some recommended scope power levels and the distances where they may be efficiently used. Keep in mind that high power glass will not be as efficient as lower powered scope and optics since excessive zoom can be a bad thing. The exact same idea goes for longer ranges where the shooter needs to have enough power to see exactly where to best aim the rifle at the target.
Lens Finish for Rifle Glass
All contemporary rifle scope lenses are coated. There are different types and qualities of lens finishes. When shopping for high end rifle scope systems, Lens covering can be a significant component of defining the rifle’s capability. The glass lenses are one of the most crucial pieces of the scope considering they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses safeguards the lens surface area and even improves anti glare capabilities from excess daylight and color profiles.
About Glass Lens Coatings – HD Versus ED
Some glass makers also use “HD” or high-definition lense coatings which use different processes, polarizations, rare earth compounds, and elements to enhance different colors and viewable definition through lenses. This high-def coating is frequently used with more costly high density glass which drops light’s capability to refract through the lens glass. Some scope vendors use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be noticeable over things with well defined shapes as light hits the object from certain angles.
Single Scope Lens Covering Versus Multi-Coating
Various optic lenses can likewise have various coverings applied to them. All lenses normally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is usually a protective and boosting 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 optic. The quality of a single coated lens depends on the scope designer and how much you spent for it. The scope’s maker and cost are indications 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 maker’s lens treatment innovation and the quality of products used in developing the rifle scope.
Anti-water Lens Coatings
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Alternatives for Installing Rifle Glass on Firearms
Installing solutions for scopes are available in a couple of options. There are the basic scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also normally are made in quick release variations which use throw levers which enable rifle operators to rapidly install and remove the scopes.
Scope Mounting Solutions with Hex Key Rings
Basic, clamp type mounting scope rings use hex head screws to install to the flattop design Picatinny scope mounting rails on rifles. These styles of scope mounts use a pair of independent rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are created for long distance precision shooting. This kind of scope mount is good for rifles which are in need of a resilient, unfailing mount which will not change regardless of how much the scope is moved about or jarring the rifle takes. These are the design of mounts you want for a devoted optics setup on a far away hunting or hard target interdiction firearm that will hardly ever need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to stop the hex screws from backing out after they are mounted securely in position. An example of these rings are the 30mm type from the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle. Several scopes can also be swapped out if they all use a complementary style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while retaining precision. These types of mounts come in beneficial for rifles which are carried a lot, to remove the optic from the rifle for protection, or for aiming systems which are utilized in between numerous rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle optic can ruin a day of shooting and your pricey optic by bringing about fogging and creating residue inside of the scope tube. Most scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Scope Gas Purging
Another element of preventing the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the glass is less influenced by climate changes and pressure differences from the outside environment which might possibly allow water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
