Rifle scopes enable you to precisely aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by making use of a series of lenses within the scope. The scope’s alignment can be adjusted for consideration of different environmental considerations like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the target. Many contemporary rifle scopes and optics have about eleven parts which are found within and outside of the scope body. These optic pieces include the rifle scope’s body, lenses, windage dials, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
About Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the optimal type of rifle glass is based around what type of shooting you plan on doing.
First Focal Plane Glass Details
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who know their target “hold over” and also “lead” correlations for their rifles
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle to the rear of 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 measurement.
- Far away forms of shooting where shooters have more time to make ballistic computations
- Shooting where most shots happen within much shorter ranges and spaces
- Shooters who would like a clearer optic picture without space used up by the larger sized FFP reticle
Rifle Glass Zoom
The amount of zoom a scope provides is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info About Fixed Single Power Lens Rifle Optics
A single power rifle scope and optic comes with a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not change given that it is set from the factory.
Info About Variable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. It will list the zoom level in a format like 2-10×32. These numbers indicate the zoom of the scope can be set between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power adjustment is accomplished 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 Glass
Here are some recommended scope power levels and the ranges where they may be effectively used. Bear in mind that higher power scopes will not be as effective as lower powered glass due to the fact that too much magnification can be a negative thing in certain situations. The same concept goes for longer ranges where the shooter needs adequate power to see exactly where to best aim the rifle at the target.
Info on Rifle Optic Lens Coatings
All modern-day rifle scope lenses are layered. There are different types and qualities of coverings. Lens finish is an important element of a rifle’s setup when looking at high-end rifle optics and scope systems. The lenses are among the most critical parts of the optic since they are what your eye sees through while sighting a rifle in on the point of impact. The coating on the lenses shields the lens surface area as well as assists with anti glare capabilities from excess light and color visibility.
HD Versus ED Rifle Optic Lens Coatings
Some scope brands also use “HD” or high-definition lens coverings which use different techniques, aspects, chemicals, and polarizations to draw out different colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finish Versus Multi-Coating for Glass
Various optic lenses can also have different coatings applied to them. All lenses typically have at least some type of treatment or finish applied to them before being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t simply a raw piece of glass. 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 VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope manufacturers similarly make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in building the rifle scope.
Hydrophobic Lens Coatings
Water on an optical lens does not support preserving a clear sight picture through a scope in any way. Many top of the line and premium scope makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It provides protection for the exterior surfaces of the Steiner glass lens so the water particles can not bind to it or develop surface tension. The outcome is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Choices for Installing Rifle Glass on Firearms
Mounting options for scopes are available in a few choices. 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 usually come in quick release versions which use throw levers which permit rifle shooters to quickly install and remove the scopes.
Rifle Optic Mounting Solutions with Hex Key Rings
Standard, clamp style mounting optic rings use hex head screws to install to the flattop style Picatinny scope mount rails on the tops of rifles. These forms of scope mounts use a pair of individual rings to support the scope, and are normally made from 7075 T6 billet aluminum which are manufactured for long distance precision shooting. This kind of scope mount is very good for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or jarring the rifle takes. These are the type of mounts you want for a dedicated optics system on a reach out and touch someone hunting or hard target interdiction firearm that will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount screws to protect against the hex screw threads from backing out after they are mounted safely 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 take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, a number of scopes can also be swapped out. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach solidly to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping accuracy. These types of mounts are useful and handy for shooting platforms which are hauled around a lot, to take off the glass from the rifle for protection, or for optics which are used between several rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It typically costs around $250 USD
Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can wreck a day on the range and your pricey optic by inducing fogging and creating residue inside of the scope’s tube. A lot of scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof. Normally, these scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture content avoidance for basic use rifles, unless you intend on taking your rifle on a boat and are concerned about the scope still performing if it goes over the side and you can still rescue the gun.
Gas Purged Glass Tubes
Another part of avoiding the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the scope is less affected by condition shifts and pressure variations from the outside environment which could possibly allow water vapor to leak 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.
