About Rifle Scopes
Rifle scopes allow you to precisely align a rifle at various targets by lining up your eye with the target at range. They do this through magnifying the target by using a set of lenses within the scope. The scope’s alignment can be adjusted for the consideration of different environmental considerations like wind and elevation to account for bullet drop.
The scope’s function is to understand exactly where the bullet will land based upon the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the target. Many modern rifle scopes and optics have around eleven parts which are located inside and externally on the scope body. These optic pieces include the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other components. Learn about the eleven parts of rifle glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The sort of focal plane an optic has establishes where the reticle or crosshair lies in connection with the optic’s magnification. It simply suggests the reticle is situated behind or before the magnification lens of the optic. Picking out the most ideal type of rifle glass is based upon what variety of shooting or hunting you plan on undertaking.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are very little
- Experienced shooters who recognize their target “hold over” and “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 About Second Focal Plane Scopes
Second focal plane glass (SFP) feature the reticle to the rear of the zoom lens. This causes the reticle to remain at the same dimensions in connection with the volume of magnification being used. The final result is that the reticle dimensions shift based upon the zoom used to shoot over longer distances considering that the reticle measurements represent various increments which can vary with the zoom level. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These styles of scopes work for:
- Far away kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots take place within shorter ranges and proximities
- Shooters who like a clearer optic sight picture without room taken up by the enlarged FFP reticle
Ins and Outs of Rifle Scope Zoom
The amount of magnification a scope supplies is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Info About Single Power Lens Scopes
A single power rifle optic will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not adjust since it is a fixed power optic.
Variable Power Lens Glass
Variable power rifle scopes can be modified between magnified levels. The power modification is performed by using the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range of Optics
Here are some suggested scope power settings and the ranges where they could be successfully used. High power scopes will not be as useful as lower magnification level scopes given that too much magnification can be a bad thing. The very same idea goes for longer ranges where the shooter needs to have increased power to see where to properly aim the rifle at the target.
Optic Lens Finish
All modern-day rifle optic and scope lenses are coated. There are various types and qualities of glass coatings. When thinking about high end rifle optics and scope setups, Lens covering can be an essential component of a rifle. The glass lenses are among the most essential parts of the optic considering they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens surface area as well as improves anti glare from excess sunlight and color profiles.
HD Versus ED Lens Coatings
Some scope brands also use “HD” or high-definition lens coverings which use different techniques, chemicals, polarizations, and components to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Optic Lens Single Coating Versus Multi-Coating
Different optic lenses can also have various finishes used to them. All lenses generally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope company and the amount you spent on it. Both are indications of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the maker’s lens treatment technology and the quality of products used in building the rifle scope.
Anti-water Optic Lens Covering
Water on a lens doesn’t help with maintaining 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 anti-water covering.
Optic Installing Alternatives
Installing approaches for scopes come in a couple of choices. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also generally are made in quick release versions which use manual levers which allow rifle shooters to rapidly mount and remove the scopes.
Hex Key Optic Ring Mounting Solutions
Standard, clamp design mounting optic rings use hex head screws to install to the flattop design Picatinny scope mount rails on the tops of rifles. These styles of scope mounts use two individual rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are made for long distance precision shooting. This type of scope mount is exceptional for rifles which require a resilient, hard use mount which will not change no matter how much the scope is moved or jarring the rifle takes. These are the type of mounts you should have for a specialized scope setup on a long distance scouting or competitors rifle which will seldom need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on screws to protect against the hex screws from wiggling out after they are mounted tightly in place. An example of these mounting rings are the 30mm style made by the Vortex Optics company. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounts
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, several scopes can also be swapped in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping the original sighting settings. These types of mounts come in convenient for shooting platforms which are transferred between vehicles a lot, to remove the scope from the rifle for protection, or for aiming systems which are chosen for use between numerous rifles. An example of this mount type is the 30mm mount from Vortex Optics. It typically costs around $250 USD
Info Around Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day on the range and your pricey optic by resulting in fogging and developing residue within the scope tube. A lot of optics prevent moisture from entering the optical tube with a system of sealing O-rings which are water resistant. Generally, these water-resistant optics can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture avoidance for standard use rifles, unless you intend on taking your rifle sailing and are concerned about the optic still working if it goes over the side and you can still rescue the rifle.
Gas Purged Scope Tubes
Another part of avoiding the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the scope is less affected by climate alterations and pressure variations from the external environment which could potentially permit 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 seek out.
