Rifle Scope Details
Rifle scopes permit you to specifically aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom by making use of a set of lenses inside the scope. The scope’s positioning can be adapted for the consideration of different environmental elements like wind speed and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the target. Many contemporary rifle optics have about eleven parts which are arranged within and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other components. Learn about the eleven parts of rifle glass.
About Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the finest type of rifle glass is based around what type of shooting you plan on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This triggers the reticle to increase in size based upon the extent of magnification being used. The result is that the reticle measurements are the same at the amplified range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at one hundred yards with 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are minor
- Experienced shooters who recognize their target “hold over” as well as “lead” ratios for their weapon
- Shooters who don’t mind the reticle is enlarged and requires more visual sight space than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle behind the magnification 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 forms of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots happen within much shorter ranges and spaces
- Shooters who want a clearer optic sight picture without area used up by the bigger FFP reticle
Ins and Outs of Optic Magnification
The quantity of zoom a scope offers is determined by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info on Single Power Lens Scopes
A single power rifle scope and optic uses a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not fluctuate considering that it is set from the factory.
Variable Power Lens Rifle Optics
Variable power rifle scopes can be tweaked between magnified levels. The power modification is performed using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some suggested scope power settings and the ranges where they can be effectively used. High power glass will not be as efficient as lower powered optics given that too much zoom can be a bad thing. The same concept goes for extended ranges where the shooter needs increased power to see precisely where to best aim the rifle at the target.
Rifle Scope Lens Covering
All contemporary rifle scope lenses are covered. Lens covering is a vital aspect of a rifle system when looking into high end rifle optics and scope systems.
Info on Lens Coatings – HD Versus ED
Some glass companies additionally use “HD” or high-definition lens coverings which employ different processes, polarizations, rare earth compounds, and elements to enhance separate color ranges and viewable target definition through the lens. This HD coating is normally used with more costly, high density glass which brings down light’s chance to refract by means of the lens glass. Some scope vendors use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration is often obvious around items with defined shapes as light hits the item from certain angles.
Single Rifle Optic Lens Coating Versus Multi-Coating
Different optic lenses can also have various finishes 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. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It needs to have a covering placed on it so that the lens will be optimally usable in numerous kinds of environments, degrees of light (full VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing 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 on the scope company and how much money you spent on it. Both the make and cost are indications of the lens quality.
Some scope producers similarly make it a point to specify if their optic lenses are covered or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Info on Anti-water Finishing
Water on an optic’s lens doesn’t improve keeping a clear sight picture through a scope in any way. Many top of the line or premium scope manufacturers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It deals with the surface of the Steiner glass lens so the H2O molecules can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Choices for Installing Rifle Glass on Firearms
Mounting solutions for scopes are available in a couple of choices. There are the basic scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally can be found in quick release variations which use throw levers which permit rifle operators to rapidly install and remove the glass.
Hex Key Scope Rings
Basic, clamp-on style mounting optic rings use hex head screws to position to the flattop design Picatinny scope mount rails on rifles. These varieties of scope mounts use two individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are created for long distance precision shooting. This type of scope mount is great for rifle systems which are in need of a durable, unfailing mount which will not shift despite how much the scope is moved about or abuse the rifle takes. These are the type of mounts you want for a devoted optics system on a far away hunting or hard target interdiction rifle that will almost never need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the mount’s screws to keep the hex screw threads from wiggling out after they are installed safely in place. An example of these mounting rings are the 30mm style from Vortex Optics. The set usually costs around $200 USD
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle. If they all use a comparable style mount, a number of scopes can also be switched out. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten solidly 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 while keeping the original sighting settings. These types of mounts are useful and practical for rifles which are transferred between vehicles a lot, to take off the optic from the rifle for protection, or for aiming systems which are chosen for use between multiple rifles. An example of this mount type is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle scope can mess up a day of shooting and your expensive optic by triggering fogging and developing residue inside of the scope tube. Most scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
About Glass Tube Gas Purging
Another part of preventing the buildup of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the optic is less affected by temperature changes and pressure distinctions from the outside environment which might possibly enable water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
