Rifle scopes permit you to exactly aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by utilizing a series of lenses inside the scope. The scope’s positioning can be adjusted for consideration of varied natural considerations like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to understand precisely where the bullet will land based on the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes have around 11 parts which are arranged within and externally on the scope. These parts include the rifle scope’s body, lenses, modification dials or turrets, focus rings, and other elements. Learn about the eleven parts of scopes.
About Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the finest type of rifle optic is based around what type of shooting you plan to do.
Info About First Focal Plane Glass
First focal plane glass (FFP) include the reticle before the magnifying lens. This triggers the reticle to increase in size based on the extent of magnification being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non magnified distance. As an example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the corresponding tick at one hundred yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are minor
- Experienced shooters who have an idea for their target “hold over” and “lead” correlations for their long guns
- Shooters who do not mind the reticle is bigger and uses up more visual eyesight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle behind 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 reticle measurement.
- Far away types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots take place within much shorter ranges and spaces
- Shooters who select a clearer optic sight picture without room used up by the enlarged FFP reticle
Zoom for Glass
The amount of magnification a scope supplies is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Scope Details
A single power rifle optic and scope will have a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not fluctuate given that it is set from the factory.
About Variable Power Lens Glass
Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will list the magnification level in a configuration such as 2-10×32. These numbers imply the magnification of the scope can be changed between 2x and 10x power. This additionally involves the power levels in-between 2 and 10. The power manipulation is achieved by operating the power ring part of the scope near the rear of the scope by the eye bell piece.
Rifle Scope Power and Ranges
Here are some advised scope power levels and the ranges where they can be effectively used. Always remember that higher magnification optics and scopes will not be as practical as lower powered scopes due to the fact that increased magnification can be a detractor. The exact same idea applies to longer distances where the shooter needs to have adequate power to see where to properly aim the rifle at the target.
Info on Rifle Scope Lens Finishes
All contemporary rifle glass lenses are coated. Lens finish can be an important element of a rifle system when considering high end rifle optics and scope systems.
Details on Lens Coatings – HD Versus ED
Some rifle glass suppliers will also use “HD” or high-definition lense coatings which apply different procedures, chemical applications, polarizations, and components to enhance various colors and viewable definition through lenses. This high-def coating is often used with increased density glass which lowers light’s ability to refract through the lens glass. Some scope vendors use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration may be obvious around objects with hard shapes as light hits the item from various angles.
Single Covering Versus Multi-Coating for Rifle 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 assembly. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It needs to have a finish placed on it so that it will be efficiently usable in numerous types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and just how much you paid for it. Both are indicators of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Details on Hydrophobic Finishing
Water on an optical lens does not support preserving a clear sight picture through a scope in any way. Numerous top of the line or premium optic makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the surface of the Steiner glass lens so the H2O molecules can not bind to it or develop surface tension. The result is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Glass Installing Choices
Mounting solutions for scopes can be found 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 various kinds of mounts also generally come in quick release versions which use throw levers which permit rifle operators to rapidly install and dismount the scopes.
Hex Key Rifle Glass Ring Mounting Solutions
Standard, clamp-on design mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on rifles. These varieties of scope mounts use double detached rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are created for far away accuracy shooting. This kind of scope mount is ideal for rifle systems which are in need of a long lasting, rock solid mount which will not change regardless of how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should have for a dedicated optics system on a far away hunting or hard target interdiction long gun that will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to protect against the hex screw threads from wiggling out after they are installed tightly in position. An example of these mounting rings are the 30mm style from Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Scope Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle. A wide range of scopes can also be swapped out if they all use a similar designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving precision. These types of mounts are useful and convenient for rifles which are moved a lot, to take off the scope glass from the rifle for protection, or for optics which are adopted between a number of rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle optic can ruin a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. Most scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Scope Tubes
Another component of avoiding the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the glass is less impacted by climate changes and pressure distinctions from the outside environment which may 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 seek out.
