Rifle scopes enable you to exactly align a rifle at different targets by lining up your eye with the target at range. They do this through zoom by utilizing a series of lenses within the scope. The scope’s positioning can be adapted for the consideration of numerous natural considerations like wind and elevation increases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based on the sight picture you are viewing with the optic as you line up 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 found within and outside of the scope. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other elements. See all eleven parts of scopes.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane a scope has determines where the reticle or crosshair is located in connection with the optic’s zoom. It literally indicates the reticle is behind or ahead of the magnification lens of the optic. Choosing the most desired style of rifle optic is based upon what kind of shooting you intend on doing.
First Focal Plane Glass Details
First focal plane scopes (FFP) feature the reticle ahead of the magnifying lens. This triggers the reticle to increase in size based upon the extent of magnification being used. The result 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 without “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are marginal
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” relationships for their rifles
- Shooters who don’t mind the reticle is bigger and requires more visual sight space than a SFP reticle
Second Focal Plane Glass Info
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. This triggers the reticle to stay at the very same size relative to the volume of zoom being used. The final result is that the reticle dimensions adjust based on the zoom employed to shoot over lengthier ranges considering that the reticle measurements present various increments which can vary with the magnification level. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These styles of glass work for:
- Far away styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots occur within shorter distances and ranges
- Shooters who select a clearer optic picture without area used up by the enlarged FFP reticle
Ins and Outs of Rifle Glass Magnification
The extent of scope magnification you need depends upon the style of shooting you would like to do. Practically every kind of rifle glass gives some amount of magnification. The quantity of magnification a scope gives is identified by the dimension, density, and curvatures of the lenses inside of the rifle optic. The magnification of the scope is the “power” of the opic. This means what the shooter is observing through the scope is magnified times the power factor of what can usually be seen by human eyes.
Single Power Lens Rifle Optic Info
A single power rifle optic and scope comes with a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not change considering that it is a fixed power optic.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes use variable power levels. The power adjustment is achieved by using the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power Level and Ranges
Here are some recommended scope powers and the distances where they may be successfully used. Highly magnified glass will not be as beneficial as lower powered optics due to the fact that too much zoom can be a negative aspect depending on your shooting distance. The very same idea applies to extended ranges where the shooter needs to have increased power to see exactly where to best aim the rifle.
Rifle Scope Lens Coating
All modern rifle optic and scope lenses are covered. Lens covering can be a significant element of a shooting system when looking into high end rifle optics and scope systems.
HD Versus ED Lenses
Some scope makers likewise use “HD” or high-definition lens coatings which use various processes, elements, polarizations, and chemicals to draw out separate colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Coating Versus Multi-Coating for Rifle Scopes
Different optic lenses can also have various finishings applied to them. All lenses normally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle scope.
Hydrophobic Lens Finishes
Water on a lens doesn’t assist with keeping a clear sight picture through an optic whatsoever. Many top of the line or high-end optic producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the exterior of the Steiner glass lens so the water particles can not bind to it or produce surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Rifle Scope Installation Options
Installing approaches for scopes are available in a couple of choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also typically come in quick release variations which use manual levers which permit rifle operators to rapidly mount and dismount the scope.
Glass Mounting Solutions with Hex Key Rings
Basic, clamp-on style mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on rifles. These varieties of scope mounts use double independent rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are manufactured for far away accuracy shooting. This type of scope mount is excellent for rifle systems which are in need of a resilient, hard use mount which will not change regardless of just how much the scope is moved about or abuse the rifle takes. These are the style of mounts you should get for a devoted optics setup on a far away hunting or tournament rifle that will almost never need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to protect against the hex screws from backing out after they are installed tightly in position. An example of these rings are the 30mm style made by the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, several scopes can also be swapped out. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten tightly to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining the original sighting settings. These kinds of mounts come in practical for shooting platforms which are transferred a lot, to remove the scope from the rifle for protection, or for optics which are used in between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. A lot of scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Optic Tubes
Another element of preventing the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the scope is less influenced by climate alterations and pressure distinctions from the outside environment which might possibly enable water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
