Information About Rifle Optics
Rifle scopes permit you to precisely aim a rifle at various targets by lining up your eye with the target over a range. They accomplish this through zoom by using a series of lenses within the scope. The scope’s alignment can be dialed in to account for different natural things like wind and elevation to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle scopes have around eleven parts which are located internally and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, modification turrets, objective focus rings, and other elements. Learn about the eleven parts of scopes.
About Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane an optic has identifies where the reticle or crosshair is located in connection with the scopes magnification. It actually means the reticle is behind or ahead of the magnifying lens of the optic. Deciding upon the most beneficial type of rifle glass is based on what type of shooting you intend on undertaking.
Info About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are minor
- Experienced shooters who understand their target “hold over” and also “lead” equations for their firearms
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle to the rear of the magnifying lens. This triggers the reticle to stay at the exact same scale in relation to the amount of magnification being used. The result is that the reticle measurements shift based on the magnification applied to shoot over longer distances given that the reticle measurements present various increments which fluctuate with the zoom level. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These types of glass work for:
- Long distance styles of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots take place within shorter spaces and ranges
- Shooters who would like a clearer optic picture with less space taken up by the bigger FFP reticle
About Scope Magnification
The amount of zoom a scope provides is determined by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Info on Single Power Lens Scopes
A single power rifle optic and scope will have a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not change since it is a fixed power scope.
Info About Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be changed between magnification power levels. These types of scopes will list the magnification degree in a configuration such as 2-10×32. These numbers mean the magnification of the scope could be set between 2x and 10x power. This also utilizes the powers in-between 2 and 10. The power manipulation is achieved by employing the power ring component of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope power settings and the ranges where they could be successfully used. Bear in mind that high power glass will not be as effective as lower magnification level scopes because increased zoom can be a detractor. The same idea goes for longer ranges where the shooter needs enough power to see precisely where to properly aim the rifle at the target.
Details on Rifle Scope Lens Coatings
All contemporary rifle optic and scope lenses are coated. There are different types and qualities of glass coverings. When considering high end rifle optical units, Lens covering can be a critical component of defining the rifle’s capability. The lenses are one of the most significant pieces 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 protects the lens surface area and even assists with anti glare capabilities from refracted sunrays and color recognition.
ED Versus HD Rifle Glass
Some scope suppliers also use “HD” or high-definition lense coverings that use various procedures, elements, rare earth compounds, and polarizations to enhance numerous colors and viewable target definition through the lens. This high-definition covering is often used with more costly, high density glass which drops light’s opportunity to refract through the lens glass. Some scope corporations use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious over things with defined outlines as light hits the object from particular angles.
Details on Single Coating Versus Multi-Coating
Different 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. This is because the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It must have a covering placed on it so that it will be efficiently usable in many kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are layered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in building the rifle scope.
Hydrophobic Coating for Rifle Glass
Water on an optical lens does not help with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior of the Steiner optic lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads move off of the scope to maintain a clear, water free sight picture.
Glass Installation Options
Mounting solutions for scopes can be found in a few choices. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also typically are made in quick release variations which use toss levers which enable rifle operators to rapidly mount and remove the optics.
Glass Mounting Solutions with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These styles of scope mounts use a pair of separate rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance precision shooting. This kind of scope mount is effective for rifle systems which are in need of a resilient, rock solid mount which will not shift despite how much the scope is moved or jarring the rifle takes. These are the design of mounts you really want to have for a specialized scope system on a reach out and touch someone scouting or competitors firearm that will hardly ever need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used to prevent the hex screw threads from wiggling out after they are mounted safely in place. An example of these mounting rings are the 30mm type made by the Vortex Optics brand. The set typically costs around $200 USD
Rifle Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible style mount. These types of mounts are handy for rifles which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between several rifles or are situationally focused.
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle optic can mess up a day on the range and your highly-priced optic by triggering fogging and making residue within the scope tube. The majority of optics protect against wetness from getting in the optical tube with a series of sealing O-rings which are water resistant. Typically, these water-resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture prevention for common use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on boats and are worried about the scope still performing if it is submerged in water and you can still recover the firearm.
About Rifle Glass Tube Gas Purging
Another part of preventing the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the optic is less impacted by condition alterations and pressure differences from the outdoor environment which could possibly enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
