Rifle scopes permit you to specifically align a rifle at different targets by lining up your eye with the target over a range. They accomplish this through magnification by utilizing a series of lenses within the scope. The scope’s alignment can be adapted for consideration of various natural things like wind speed and elevation increases to account 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 optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle optics have about eleven parts which are found internally and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, modification dials or turrets, focus rings, and other parts. Learn about the eleven parts of glass.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the best type of rifle optic depends on what type of shooting you plan to do.
First Focal Plane Optic Facts
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where calculations are minimal
- Experienced shooters who understand their aim point “hold over” as well as “lead” ratios for their firearms
- Shooters who do not mind the reticle is enlarged and occupies more visual sight space than a SFP reticle
About 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” 100 yard tick measurement would be 1/5th of the non “zoom” tick.
- Long distance forms of shooting where shooters have additional time to make ballistic computations
- Shooting where most of the shots occur within shorter ranges and spaces
- Shooters who like a clearer optic picture with less room used up by the larger size FFP reticle
Magnification for Scopes
The quantity of scope zoom you need depends upon the style of shooting you intend to do. Nearly every kind of rifle glass gives some degree of zoom. The amount of zoom a scope provides is determined by the size, thickness, and curves of the lenses inside of the rifle scope. The magnification level of the scope is the “power” of the scope. This signifies what the shooter is looking at through the scope is amplified times the power factor of what can normally be seen by human eyes.
Single Power Lens Scope Details
A single power rifle optic or scope will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not adjust given that it is set from the factory.
Adjustable Power Lens Scopes
Variable power rifle scopes can be adjusted between magnification power levels. These types of scopes will note the magnification degree in a format such as 2-10×32. These numbers suggest the zoom of the scope could be set between 2x and 10x power. This also involves the powers in-between 2 and 10. The power manipulation is accomplished by applying the power ring component of the scope near the back of the scope by the eye bell piece.
Power and Range
Here are some recommended scope power settings and the distances where they may be efficiently used. Always remember that high power scopes will not be as practical as lower magnification level optics since increased zoom can be a negative thing in certain situations. The exact same idea relates to extended distances where the shooter needs sufficient power to see exactly where to properly aim the rifle.
About Lens Coverings
All modern-day rifle optic lenses are layered. Lens finish can be a vital aspect of a rifle’s setup when considering high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope producers also use “HD” or high-definition lens coatings which use different methods, aspects, polarizations, and chemicals to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Rifle Scope Lens Coating Versus Multi-Coating
Various optic lenses can also have various finishings applied to them. All lenses typically have at least some kind of treatment or covering applied to them before being used in a rifle scope or optic assembly. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally functional in many kinds of environments, degrees of light (full light VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers likewise make it a point to define if their optic lenses are layered or “multi” covered. This indicates the lens has several treatments applied to them. If a lens gets numerous treatments, it can show that a company is taking several steps to combat different natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This additionally doesn’t always suggest the multi-coated lens will perform better than a single layered lens. Being “better” hinges on the maker’s lens treatment techniques and the quality of products used in developing the rifle scope.
What to Know About Hydrophobic Coating
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic coating.
Choices for Installing Rifle Optics on Long Guns
Mounting options for scopes come in a few options. There are the standard scope rings which are separately mounted to the scope 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 permit rifle operators to quickly install and remove the glass.
Rifle Glass Mounting Solutions with Hex Key Rings
Standard, clamp-on style mounting optic rings use hex head screws to install to the flattop design Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use double independent rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are created for far away accuracy shooting. This form of scope mount is ideal for rifle systems which require a long lasting, unfailing mount which will not shift regardless of how much the scope is moved or jarring the rifle takes. These are the design of mounts you want for a devoted optics setup on a far away scouting or sniper competition long gun which will pretty much never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on screws to stop the hex screws from backing out after they are mounted safely in place. An example of these rings are the 30mm type from the Vortex Optics company. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Scope 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 switched out if they all use a similar style mount. These types of mounts are handy for long guns which are transferred a lot, to remove the optic from the rifle for protection, or for optics which are used in between several rifles.
Info Around Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your costly optic by triggering fogging and creating residue inside of the scope tube. Many scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Rifle Optic Gas Purging
Another element of avoiding the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the glass is less altered by temp alterations and pressure distinctions from the external environment which may potentially enable water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
