What You Need to Know About Rifle Optics
Rifle scopes allow you to exactly align a rifle at various targets by lining up your eye with the target at range. They do this through zoom by making use of a series of lenses inside the scope. The scope’s alignment can be adapted for consideration of separate natural factors like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the target. The majority of contemporary rifle optics have about eleven parts which are arranged within and outside of the scope body. These parts consist of the rifle scope’s body, lenses, windage dials, focus rings, and other components. Learn about the eleven parts of glass.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the perfect type of rifle scope is based around what type of shooting you plan to do.
Info About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This induces the reticle to increase in size based upon the level of magnification being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non amplified range. For instance, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are small
- Experienced shooters who recognize their target “hold over” plus “lead” equations for their long gun
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Far away forms of shooting where shooters have more time to make ballistic computations
- Shooting where most shots take place within much shorter ranges and spaces
- Shooters who prefer a clearer optic sight picture without space used up by the bigger FFP reticle
Rifle Scope Magnification
The measure of scope zoom you need depends upon the form of shooting you want to do. Practically every kind of rifle optic delivers some level of zoom. The quantity of magnification a scope delivers is determined by the diameter, density, and curves of the lenses within the rifle scope. The magnification level of the scope is the “power” of the glass. This denotes what the shooter is checking out through the scope is amplified times the power factor of what can typically be seen by human eyes.
Fixed Single Power Lens Rifle Optic Facts
A single power rifle optic and scope uses a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate given that it is fixed.
Variable Power Lens Optic Facts
Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will list the zoom level in a format like 2-10×32. These numbers mean the zoom of the scope could be changed in between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power adjustment is achieved utilizing the power ring component of the scope near the back of the scope by the eye bell piece.
The Power Level and Range of Rifle Optics
Here are some recommended scope power settings and the ranges where they can be effectively used. Bear in mind that high magnification optics and scopes will not be as effective as lower magnification level scopes because excessive magnification can be a bad thing. The same concept relates to extended ranges where the shooter needs to have enough power to see where to properly aim the rifle at the target.
Info on Rifle Scope Lens Coverings
All modern-day rifle optic and scope lenses are coated. There are various types and qualities of glass finishes. When considering high end rifle scope setups, Lens finish can be a significant aspect of defining the capability of the rifle. The glass lenses are among the most critical components of the scope given that they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses offers protection to the lens surface and even helps with anti glare capabilities from refracted sunshine and color discernibility.
HD Versus ED Lenses
Some scope makers also use “HD” or high-definition lens finishes which use various methods, components, polarizations, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Coating Versus Multi-Coating for Optics
Various scope lenses can also have different coatings applied to them. All lenses generally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic. 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 must have a coating put on it so that the lens will be optimally usable in many kinds of environments, degrees of light (full light VS shaded), and other shooting conditions.
This lens treatment can safeguard 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 producer and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are covered or “multi” covered. This means the lens has multiple treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can establish that a manufacturer is taking multiple actions to fight various natural factors like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This also doesn’t always imply the multi-coated lens will perform better than a single coated lens. Being “better” hinges on the maker’s lens treatment innovation and the quality of materials used in constructing the rifle glass.
Hydrophobic Rifle Optic Lens Coating
Water on a lens doesn’t assist 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 hydrophobic or hydrophilic anti-water covering.
Alternatives for Installing Optics on Firearms
Installing options for scopes come in a couple of options. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically can be found in quick release variations which use throw levers which permit rifle operators to rapidly mount and dismount the scopes.
Scope Mounting Solutions with Hex Key Rings
Standard, clamp type mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These varieties of scope mounts use double individual rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are created for far away precision shooting. This kind of scope mount is good for rifles which need to have a resilient, rock solid mount which will not move no matter how much the scope is moved about or abuse the rifle takes. These are the style of mounts you should get for a dedicated scope setup on a reach out and touch someone hunting or sniper competition rifle that will almost never need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to keep the hex screw threads from wiggling out after they are installed tightly in place. An example of these rings are the 30mm type made by Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Scope Rings
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, several scopes can often be swapped out in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top type 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 accuracy. These types of mounts are useful and handy for shooting platforms which are moved a lot, to remove the optic from the rifle for protection, or for scopes which are chosen for use between a number of rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
Info on Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can mess up a day on the range and your expensive optic by resulting in fogging and creating residue inside of the scope’s tube. Many optics prevent moisture from entering the scope tube with a series of sealing O-rings which are water resistant. Usually, these water resistant optics can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of humidity avoidance for basic use rifles, unless you anticipate taking your rifle aboard a watercraft and are concerned about the scope still working if it goes overboard and you can still recover the rifle.
Details on Rifle Glass Tube Gas Purging
Another part of preventing the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the glass is less altered by temperature alterations and pressure distinctions from the outside environment which could possibly permit water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
