Optic Details
Rifle scopes permit you to exactly align a rifle at various targets by lining up your eye with the target at range. They do this through magnifying the target by using a set of lenses within the scope. The scope’s positioning can be adjusted for consideration of different natural considerations like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based upon the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle scopes and optics have about eleven parts which are arranged inside and externally on the scope body. These scope parts consist of the rifle scope’s body, lenses, elevation dials, objective focus rings, and other elements. See all eleven parts of an optic.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the optimal type of rifle scope is based around what type of shooting you plan on doing.
First Focal Plane Glass Details
First focal plane optics (FFP) come with the reticle ahead of the zoom lens. This causes the reticle to increase in size based upon the amount of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified range. For example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are minimal
- Experienced shooters who understand their target “hold over” as well as “lead” correlations for their weapon
- Shooters who do not mind the reticle is bigger and requires more visual sight room than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle behind the zoom lens. 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 measurement.
- Far away kinds of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots occur within shorter spaces and ranges
- Shooters who would like a clearer optic sight picture without room used up by the bigger FFP reticle
Scope Zoom
The amount of scope zoom you need on your scope depends upon the form of shooting you plan to do. Just about every kind of rifle optic provides some level of magnification. The quantity of magnification a scope offers is identified by the diameter, thickness, and curves of the lens glass within the rifle optic. The magnification level of the optic is the “power” of the opic. This indicates what the shooter is looking at through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Info About Fixed Power Lens Rifle Scopes
A single power rifle optic or scope comes with a zoom 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 type of optic can not fluctuate considering that it is fixed.
Info About Variable Power Lens Rifle Glass
Variable power rifle scopes use enhanced power. The power adjustment is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some suggested scope powers and the ranges where they can be efficiently used. Always remember that higher magnification optics will not be as practical as lower powered scopes since excessive zoom can be a detractor. The exact same idea goes for longer distances where the shooter needs increased power to see exactly where to properly aim the rifle at the target.
Details on Rifle Optic Lens Covering
All modern rifle optic and scope lenses are covered in special coatings. There are different types and qualities of coverings. When shopping for luxury rifle optical devices, Lens coating can be a crucial element of defining the rifle’s capability. The lenses are one of the most crucial pieces of the glass as they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses shields the lens surface area and helps with anti glare capabilities from excess light and color discernibility.
HD Versus ED Lens Coatings
Some scope producers also use “HD” or high-definition lens coatings which use different processes, aspects, chemicals, and polarizations to draw out different colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
About Single Covering Versus Multi-Coating
Different optic lenses can also have various coatings applied to them. All lenses generally have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic assembly. This is since the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It must have a coating applied to it so that it will be efficiently usable in lots of kinds of environments, degrees of sunshine (full VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while decreasing glare and other less useful 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 manufacturers also make it a point to specify if their optic lenses are coated or “multi” coated. This implies the lens has numerous treatments applied to them. If a lens gets several treatments, it can establish that a manufacturer is taking numerous steps to combat various environmental factors like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This also does not always indicate the multi-coated lens is better than a single coated lens. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle glass.
Info on Anti-water Coating
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Many top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic anti-water covering.
Scope Installing Alternatives
Installing approaches for scopes come in a couple of options. There are the basic scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually can be found in quick release versions which use toss levers which allow rifle operators to rapidly install and dismount the scopes.
Rifle Glass Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are made from 7075 T6 billet aluminum which is designed for long range accuracy shooting. This type of scope mount is excellent for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Optic Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can often be switched in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely 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 back on the rifle while retaining precision. These kinds of mounts are useful and convenient for rifles which are moved around a lot, to remove the optic from the rifle for protection, or for aiming systems which are employed in between a number of rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It normally costs around $250 USD
What to Know About Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can spoil a day on the range and your pricey optic by inducing fogging and generating residue inside of the scope’s tube. Most scopes prevent wetness from getting in the scope tube with a series of sealing O-rings which are waterproof. Generally, these water resistant scopes can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient humidity prevention for conventional use rifles for hunting and sporting purposes, unless you anticipate taking your rifle sailing and are worried about the optic still functioning if it is submerged in water and you can still rescue the rifle.
Info on Optic Tube Gas Purging
Another part of avoiding the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the scope is less altered by condition changes and pressure distinctions from the outside environment which may potentially permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
