Info Rifle Scopes
Rifle scopes permit you to precisely aim a rifle at various targets by lining up your eye with the target over a range. They do this through magnifying the target by using a set of lenses within the scope. The scope’s alignment can be adjusted to take into account various natural considerations like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based on the sight picture you are seeing through the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle scopes and optics have about eleven parts which are found within and externally on the optic. These optic pieces include the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other parts. See all eleven parts of a scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the perfect type of rifle scope is based on what type of shooting you plan on doing.
First Focal Plane Optics
First focal plane glass (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 benefit 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 without “zoom” is still the identical tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are very little
- Experienced shooters who have an idea for their target “hold over” plus “lead” ratios for their firearm
- Shooters who do not mind the reticle is bigger and requires more visual eyesight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle to the rear of the zoom lens. This induces the reticle to remain at the exact same dimensions relative to the quantity of zoom being used. The result is that the reticle measurements change based on the zoom chosen to shoot over greater distances considering the reticle measurements represent various increments which fluctuate with the magnification. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular sorts of glass work for:
- Far away styles of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots take place within much shorter proximities and ranges
- Shooters who choose a clearer optic picture without room used up by the bigger FFP reticle
Zoom for Rifle Scopes
The quantity of zoom a scope offers is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Info on Fixed Power Lens Optics
A single power rifle scope or optic will have a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not adjust given that it is a fixed power scope.
Info on Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification levels. These types of scopes will list the magnification level in a format such as 2-10×32. These numbers imply the zoom of the scope could be adjusted between 2x and 10x power. This also incorporates the power levels in-between 2 and 10. The power manipulation is achieved using the power ring component of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope power settings and the ranges where they could be efficiently used. High power scopes will not be as beneficial as lower magnification glass since too much magnification can be a negative aspect depending on your shooting distance. The exact same concept goes for longer ranges where the shooter needs enough power to see precisely where to properly aim the rifle at the target.
Details on Lens Finishes
All top teir rifle scope lenses are covered. Lens finishing is a vital element of a shooting platform when buying high end rifle optics and scope equipment.
About Lens Coatings – HD Versus ED
Some scope brands also use “HD” or high-definition lens coverings which use various methods, polarizations, chemicals, and elements to draw out separate 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 Finish Versus Multi-Coating
Different optic lenses can also have different coverings used to them. All lenses usually have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is usually a protective and improving 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 covered lens depends on the scope company and the amount you paid for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Lens Coverings
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic finishing.
Rifle Optic Installation Options
Installing options for scopes come in a few choices. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also typically are made in quick release variations which use toss levers which permit rifle shooters to quickly mount and remove the scopes.
Hex Key Scope Rings
Basic, clamp-on style mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on rifles. These forms of scope mounts use double detached rings to support the optic, and are normally made from 7075 T6 billet aluminum which are designed for far away precision shooting. This type of scope mount is effective for rifle systems which are in need of a resilient, rock solid mount which will not move regardless of just how much the scope is moved or abuse the rifle takes. These are the type of mounts you should have for a dedicated scope system on a long distance hunting or tournament rifle that will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to stop the hex screw threads from wiggling out after they are mounted firmly in place. An example of these rings are the 30mm style from Vortex Optics. The set usually costs around $200 USD
Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle. If they all use a comparable design mount, a number of scopes can often be swapped out in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely 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 retaining precision. These kinds of mounts come in handy for shooting platforms which are transferred between vehicles a lot, to remove the optic from the rifle for protection, or for optics which are employed in between a number of rifles. An example of this mount type is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle optic can mess up a day of shooting and your expensive optic by causing fogging and creating residue inside of the scope tube. Most scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are waterproof.
About Scope Tube Gas Purging
Another component of preventing the buildup of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the optic is less impacted by temperature alterations and pressure variations from the outdoor environment which could 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.
