Rifle Optic Facts
Rifle scopes permit you to exactly aim a rifle at different targets by lining up your eye with the target over a range. They do this through magnification using a series of lenses within the scope. The scope’s positioning can be dialed in to take into account various environmental things like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes have around eleven parts which are arranged inside and externally on the optic. These parts include the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other elements. See all eleven parts of scopes.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the best type of rifle optic is based on what type of shooting you plan on doing.
First Focal Plane Optic Info
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This causes the reticle to increase in size based on the extent of zoom being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at 100 yards by using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are low
- Experienced shooters who know their aim point “hold over” and “lead” ratios for their long gun
- Shooters who do not mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Second Focal Plane Scope Info
Second focal plane glass (SFP) feature the reticle to the rear of the magnification lens. This causes the reticle to remain at the very same dimensions relative to the level of zoom being used. The outcome is that the reticle measurements evolve based upon the magnification used to shoot over greater distances given that the reticle markings represent various increments which fluctuate with the magnification. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These particular kinds of scopes work for:
- Long distance styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots take place within shorter ranges and distances
- Shooters who want a clearer optic sight picture without space taken up by the bigger FFP reticle
Ins and Outs of Optic Zoom
The amount of zoom a scope supplies is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Rifle Glass 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 type of scope can not fluctuate considering that it is a set power scope.
Adjustable Power Lens Glass Facts
Variable power rifle scopes use enhanced power. The power adjustment is accomplished by making use of the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some recommended scope powers and the distances where they can be effectively used. Consider that higher power optics and scopes will not be as effective as lower powered optics since excessive zoom can be a bad thing. The exact same concept relates to longer distances where the shooter needs to have enough power to see precisely where to properly aim the rifle.
About Scope Lens Coatings
All top teir rifle optic lenses are covered. Lens finish can be a crucial aspect of a rifle when looking at high end rifle optics and scope equipment.
HD Versus ED Lenses
Some scope makers likewise use “HD” or high-definition lens coverings which use various processes, polarizations, components, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Glass Lens Finish Versus Multi-Coating
Various optic lenses can also have different coverings applied to them. All lenses generally 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 minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and the amount you paid for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope manufacturers also make it a point to define if their optic lenses are covered or “multi” coated. This indicates the lens has numerous treatments applied to the surfaces. If a lens receives multiple treatments, it can show that a company is taking multiple actions to combat various natural elements like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This additionally does not necessarily suggest the multi-coated lens will perform better than a single covered lens. Being “better” depends on the producer’s lens treatment techniques and the quality of components used in constructing the rifle optic.
Hydrophobic Coating for Scopes
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Many top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic finish.
Alternatives for Mounting Scopes on Firearms
Installing approaches for scopes come in a couple of options. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also normally come in quick release variations which use throw levers which allow rifle shooters to rapidly install and dismount the optics.
Hex Key Rifle Optic Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long range accuracy shooting. This type of scope install is wonderful for rifles which need a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be swapped out if they all use a compatible design mount. These types of mounts are convenient for rifles which are carried a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used in between several rifles.
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. A lot of optics protect against humidity from going into the scope tube with a series of sealing O-rings which are waterproof. Usually, these scopes can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of humidity avoidance for common use rifles for hunting and sporting purposes, unless you anticipate taking your rifle aboard watercrafts and are concerned about the scope still working if it is submerged in water and you can still rescue the gun.
What to Know About Optic Tube Gas Purging
Another component of preventing the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the scope is less altered by climate shifts and pressure variations from the outside environment which could potentially allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
