Information Rifle Optics
Rifle scopes enable you to specifically aim a rifle at various targets by lining up your eye with the target over a range. They accomplish this through zoom by using a set of lenses inside the scope. The scope’s alignment can be adjusted for consideration of numerous environmental factors like wind speed and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle scopes and optics have about 11 parts which are located within and on the exterior of the optic. These optic pieces include the rifle scope’s body, lenses, elevation turrets, focus rings, and other components. See all eleven parts of optics.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the perfect type of rifle glass depends on what type of shooting you plan on doing.
First Focal Plane Scope Details
First focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This triggers the reticle to increase in size based on the amount of zoom being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who know their aim point “hold over” plus “lead” equations for their long gun
- Shooters who do not mind the reticle is enlarged and requires more visual sight room than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. This causes the reticle to stay at the exact same dimensions in connection with the amount of zoom being used. The end result is that the reticle measurements evolve based upon the magnification used to shoot over greater ranges considering that the reticle measurements present distinct increments which can vary with the zoom level. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular kinds of glass are handy for:
- Long distance types of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots occur within shorter proximities and ranges
- Shooters who prefer a clearer optic picture with less room used up by the bigger FFP reticle
Details on Rifle Scope Magnification
The quantity of magnification a scope provides is figured out by the diameter, 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 Rifle Scopes
A single power rifle scope comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust considering that it is a set power scope.
Adjustable Power Lens Rifle Scope Details
Variable power rifle scopes use variable power levels. The power adjustment is achieved by using the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range
Here are some advised scope power levels and the ranges where they could be efficiently used. High power optics will not be as effective as lower magnification level scopes given that too much zoom can be a bad thing. The very same idea relates to longer distances where the shooter needs sufficient power to see exactly where to best aim the rifle.
Info on Lens Coverings
All current rifle glass lenses are layered. Lens covering is an essential aspect of a shooting system when considering high end rifle optics and scope equipment.
About Optic Lens Coatings – HD Versus ED
Some scope producers also use “HD” or high-definition lens finishings which use different processes, polarizations, components, and chemicals to draw out various colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Info on Single Covering Versus Multi-Coating
Different optic lenses can also have different finishings applied to them. All lenses normally have at least some type of treatment or finishing used to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while lowering glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope maker and how much money you spent for it. Both the make and cost are indications of the lens quality.
Some scope producers likewise make it a point to define if their optic lenses are layered or “multi” coated. This suggests the lens has multiple treatments applied to the surfaces. If a lens receives multiple treatments, it can indicate that a company is taking numerous steps to fight various environmental aspects like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This also doesn’t necessarily indicate the multi-coated lens is much better than a single coated lens. Being “better” hinges on the producer’s lens treatment techniques and the quality of glass used in building the rifle optic.
Hydrophobic Rifle Optic Lens Finishing
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Many top of the line and military grade optic companies will coat their lenses with a hydrophobic or hydrophilic covering.
Optic Mounting Options
Mounting solutions for scopes can be found in a couple of options. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also normally come in quick release versions which use toss levers which permit rifle shooters to quickly install and dismount the scope.
Hex Key Glass Rings
Basic, clamp-on design mounting optic rings use hex head screws to position to the flattop style Picatinny scope mount rails on rifles. These forms of scope mounts use two separate rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are designed for long distance accuracy shooting. This type of scope mount is exceptional for rifles which require a resilient, rock solid mount which will not shift no matter just how much the scope is moved or abuse the rifle takes. These are the design of mounts you should get for a dedicated optics setup on a long distance hunting or interdiction long gun which will almost never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to keep the hex screws from backing out after they are installed tightly in position. An example of these rings are the 30mm style from the Vortex Optics company. The set usually costs around $200 USD
Rifle Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, a number of scopes can often be swapped out. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving accuracy. These types of mounts are useful and convenient for rifles which are moved around a lot, to remove the scope glass from the rifle for protection, or for scopes which are employed between multiple rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It normally costs around $250 USD
Info on Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by causing fogging and creating residue inside of the scope tube. A lot of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
What to Know About Optic Tube Gas Purging
Another component of avoiding the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the scope is less impacted by condition shifts and pressure differences from the outside environment which might possibly allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
