Rifle Optic Information
Rifle scopes permit you to precisely align a rifle at different targets by aligning your eye with the target over a range. They do this through zoom by utilizing a series of lenses inside the scope. The scope’s alignment can be adjusted to account for varied environmental considerations like wind and elevation increases to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended target. Many modern rifle scopes have around 11 parts which are found within and outside of the optic. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other parts. See all eleven parts of a scope.
About Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the best type of rifle glass is based around what type of shooting you plan to do.
About First Focal Plane Glass
First focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This causes the reticle to increase in size based upon the level of magnification being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the same tick at one hundred yards with 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” equations for their weapon
- Shooters who don’t mind the reticle is bigger and requires more visual sight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle behind the magnifying lens. This induces the reticle to stay at the very same size in connection with the level of magnification being used. The result is that the reticle measurements alter based on the magnification used to shoot over longer ranges considering that the markings represent various increments which differ with the magnification level. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These sorts of scopes are handy for:
- Long distance kinds of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots take place within shorter spaces and ranges
- Shooters who select a clearer optic picture without room taken up by the enlarged FFP reticle
Rifle Optic Magnification
The amount 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.
Info on Fixed Single Power Lens Rifle Optics
A single power rifle optic will have a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not fluctuate because it is a fixed power scope.
Info About Variable Power Lens Rifle Glass
Variable power rifle scopes use variable power levels. The power adjustment is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Scope Power and Range Correlation
Here are some advised scope power settings and the distances where they could be successfully used. Consider that higher magnification scopes will not be as effective as lower magnification level glass due to the fact that too much magnification can be a detractor. The exact same idea goes for extended distances where the shooter needs to have enough power to see exactly where to best aim the rifle at the target.
Info on Lens Finishing
All current rifle scope and optic lenses are coated. Lens covering is an essential element of a shooting system when thinking about high end rifle optics and scope systems.
HD Versus ED Rifle Scope Lens Coatings
Some rifle scope companies also use “HD” or high-definition glass finishes that make the most of various processes, chemicals, components, and polarizations to draw out numerous colors and viewable target visibility through lenses. This high-definition covering is normally used with greater density lens glass which brings down light’s ability to refract through the lens glass. Some scope brands use “HD” to refer to “ED” signifying extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious around items with hard edges and shapes as light hits the item from particular angles.
Rifle Glass Lens Single Coating Versus Multi-Coating
Various optic lenses can even have various finishes applied to them. All lenses normally have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is 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 shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” covered. This indicates the lens has several treatments applied to them. If a lens receives multiple treatments, it can prove that a producer is taking multiple actions to fight various environmental factors like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This additionally does not necessarily imply the multi-coated lens is better than a single covered lens. Being “better” hinges on the maker’s lens treatment innovation and the quality of products used in building the rifle glass.
Anti-water Lens Finishes
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic covering.
Options for Installing Optics on Firearms
Mounting solutions for scopes can be found in a couple of options. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also typically come in quick release versions which use throw levers which enable rifle operators to quickly mount and dismount the glass.
Hex Key Rifle Glass Rings
Basic, clamp style mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use a pair of individual rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This type of scope mount is very good for rifle systems which are in need of a long lasting, rock solid mount which will not change no matter just how much the scope is moved or jarring the rifle takes. These are the style of mounts you want for a specialized optics system on a reach out and touch someone hunting or sniper competition rifle that will rarely need to be modified or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount screws to keep the hex screw threads from wiggling out after they are mounted safely in place. An example of these mounting rings are the 30mm style made by the Vortex Optics company. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can also be switched out if they all use a compatible style mount. These types of mounts come in handy for rifle platforms which are transported a lot, to remove the optic from the rifle for protection, or for optics which are used between multiple rifles.
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle optic can ruin a day on the range and your expensive optic by resulting in fogging and developing residue within the scope tube. A lot of optics protect against humidity from getting in the optical tube with a series of sealing O-rings which are water resistant. Usually, these optics can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture content prevention for standard use rifles, unless you plan on taking your rifle on your motorboat and are worried about the optic still functioning if it is submerged in water and you can still rescue the firearm.
Info Around Glass Tube Gas Purging
Another component of preventing the accumulation of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the scope is less affected by condition alterations and pressure variations from the outside environment which may potentially permit 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 seek out.
