Rifle Optic Information
Rifle scopes enable you to precisely align a rifle at various targets by lining up your eye with the target over a distance. They do this through magnifying the target by employing a series of lenses within the scope. The scope’s alignment can be adjusted to account for many ecological elements like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are seeing via the scope as you line up the scope’s crosshair or reticle with the target. A lot of modern rifle optics have about eleven parts which are located within and outside of the scope body. These parts consist of the rifle scope’s body, lenses, windage and elevation dials or turrets, focus rings, and other components. Learn about the eleven parts of rifle optics.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the best type of rifle scope is based around what type of shooting you plan to do.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where estimations are small
- Experienced shooters who understand their aim point “hold over” and “lead” ratios for their weapon
- Shooters who don’t mind the reticle is bigger and occupies more visual sight room than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane optics (SFP) come with the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Long distance types of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots occur within much shorter proximities and ranges
- Shooters who want a clearer optic picture with less room taken up by the enlarged FFP reticle
Details on Scope Zoom
The quantity of magnification a scope offers is determined 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.
Fixed Power Lens Scope Details
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 given that it is set from the factory.
Adjustable Power Lens Scope Details
Variable power rifle scopes can be adjusted between magnification levels. It will note the magnification degree in a configuration such as 2-10×32. These numbers mean the zoom of the scope can be changed between 2x and 10x power. This always incorporates the power levels in-between 2 and 10. The power adjustment is accomplished by applying the power ring component of the scope near the back of the scope by the eye bell piece.
Rifle Optic Power and Ranges
Here are some suggested scope power levels and the distances where they could be effectively used. Bear in mind that higher magnification optics will not be as efficient as lower powered optics and scopes due to the fact that increased magnification can be a bad thing. The very same idea relates to longer distances where the shooter needs to have increased power to see exactly where to properly aim the rifle at the target.
Info on Rifle Optic Lens Coatings
All state-of-the-art rifle scope lenses are covered. Lens covering is an essential aspect of a shooting platform when thinking about high end rifle optics and scope setups.
ED Versus HD Glass
Some scope producers also use “HD” or high-definition lens coatings which use various processes, polarizations, chemicals, and elements to draw out different colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Optic Lens Single Covering Versus Multi-Coating
Different scope lenses can even have various coverings applied to them. All lenses usually have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. 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 optimally functional in many types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope designer and just how much you spent paying for it. Both the manufacturer and amount are signs of the lens quality.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” coated. This suggests the lens has had numerous treatments applied to them. If a lens receives numerous treatments, it can show that a producer is taking multiple actions to fight different environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This also doesn’t always suggest the multi-coated lens will perform better than a single coated lens. Being “better” is dependent on the producer’s lens treatment solutions and the quality of glass used in constructing the rifle scope.
Hydrophobic Coating for Glass
Water on an optical lens does not assist with keeping a clear sight picture through a scope whatsoever. Numerous top of the line or high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the surface area of the Steiner glass lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads roll off of the scope to keep a clear, water free sight picture.
Rifle Optic Mounting Alternatives
Installing options for scopes come in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally come in quick release versions which use toss levers which enable rifle operators to rapidly install and remove the glass.
Hex Key Rifle Scope Rings
Standard, clamp-on style mounting optic rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These forms of scope mounts use double detached rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope mount is very good for rifles which are in need of a resilient, rock solid mount which will not shift despite just how much the scope is moved or jarring the rifle takes. These are the type of mounts you should have for a dedicated scope setup on a far away hunting or hard target interdiction firearm which will rarely need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on screws to keep the hex screws from wiggling out after they are installed firmly in place. An example of these rings are the 30mm style made by the Vortex Optics company. The set typically costs around $200 USD
Optic Mounting Solutions 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. Several scopes can also be swapped out if they all use a similar style mount. These types of mounts are convenient for long guns which are transferred a lot, to swap out the optic from the rifle for protection, or for optics which are used between multiple rifles or are situationally focused.
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can spoil a day of shooting and your pricey optic by inducing fogging and developing residue within the scope’s tube. Most scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are water resistant. Typically, these water resistant optics can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient wetness prevention for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still performing if it goes over the side and you can still find the firearm.
What to Know About Scope Tube Gas Purging
Another part of preventing the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the glass is less affected by climate shifts and pressure distinctions from the outside environment which might potentially allow water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
