Facts About Scopes
Rifle scopes allow you to exactly align a rifle at various targets by aligning your eye with the target at range. They do this through magnification by utilizing a set of lenses inside the scope. The scope’s alignment can be adapted for consideration of varied ecological aspects like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based upon the sight picture you are viewing through the optic as you line up the scope’s crosshair or reticle with the intended target. Many modern-day rifle optics have around eleven parts which are arranged internally and externally on the scope body. These parts consist of the rifle scope’s body, lenses, adjustment dials, focus rings, and other components. See all eleven parts of a rifle scope.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane an optic has determines where the reticle or crosshair is located relative to the scopes zoom. It actually implies the reticle is behind or before the magnifying lens of the scope. Picking the most desired sort of rifle optic is based on what style of shooting you intend on undertaking.
First Focal Plane Optic Facts
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are marginal
- Experienced shooters who recognize their target “hold over” as well as “lead” relationships for their firearm
- Shooters who don’t mind the reticle is bigger and uses up more visual sight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane glass (SFP) feature the reticle behind the magnifying lens. This causes the reticle to remain at the exact same overall size relative to the amount of magnification being used. The outcome is that the reticle dimensions evolve based upon the zoom used to shoot over lengthier distances due to the fact that the reticle measurements present various increments which change with the magnification. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These styles of optics are handy for:
- Long distance styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots happen within much shorter ranges and spaces
- Shooters who choose a clearer optic sight picture with less area taken up by the bigger FFP reticle
About Glass Zoom
The quantity 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.
About Single Power Lens Rifle Optics
A single power rifle scope comes with a magnification number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not fluctuate because it is a fixed power optic.
Variable Power Lens Glass Facts
Variable power rifle scopes have adjustable power. It will note the magnification level in a format such as 2-10×32. These numbers suggest the zoom of the scope could be set between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power manipulation is achieved by applying the power ring component of the scope near the rear of the scope by the eye bell piece.
The Power and Range of Rifle Scopes
Here are some suggested scope power levels and the distances where they can be effectively used. Highly magnified glass will not be as useful as lower powered scopes because too much magnification can be a negative aspect depending on your shooting distance. The same concept goes for longer ranges where the shooter needs to have sufficient power to see where to properly aim the rifle.
Rifle Optic Lens Covering
All modern-day rifle optic and scope lenses are covered in special coatings. There are various types and qualities of glass lens coverings. Lens finish is a crucial element of a rifle when thinking of high-end rifle optics and scope systems. The lenses are among the most essential parts of the scope because they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses safeguards the lens exterior as well as improves anti glare from refracted sunlight and color recognition.
HD Versus ED Optic Lens Coatings
Some scope makers likewise use “HD” or high-definition lens coverings which use various techniques, polarizations, chemicals, and components to draw out different colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Covering Versus Multi-Coating
Different optic lenses can likewise have different coatings used to them. All lenses normally have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you paid for it.
Some scope makers similarly make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in building the rifle scope.
Anti-water Covering for Scopes
Water on an optic’s lens doesn’t improve retaining a clear sight picture through an optic whatsoever. Numerous top of the line or high-end optic makers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the exterior of the Steiner scope lens so the H2O molecules can not bind to it or produce surface tension. The result is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Scope Installation Choices
Mounting approaches for scopes can be found 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 typically are made in quick release variations which use throw levers which permit rifle operators to rapidly mount and dismount the glass.
Hex Key Rifle Glass Rings
Basic, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on the tops of rifles. These forms of scope mounts use a pair of independent rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are created for long distance precision shooting. This kind of scope mount is great for rifle systems which need a long lasting, rock solid mount which will not shift despite how much the scope is moved about or abuse the rifle takes. These are the type of mounts you really want to have for a faithful optics system on a far away hunting or sniper competition rifle that will seldom need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount screws to keep the hex screws from backing out after they are installed tightly in place. An example of these rings are the 30mm type from the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Scope Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. If they all use a similar design mount, a number of scopes can also be switched out. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect nicely to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while preserving accuracy. These kinds of mounts are useful and beneficial for shooting platforms which are hauled around a lot, to remove the scope glass from the rifle for protection, or for aiming systems which are used between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day on the range and your pricey optic by resulting in fogging and developing residue within the scope tube. Most optics prevent wetness from going into the scope tube with a system of sealing O-rings which are water resistant. Usually, these water resistant optics can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture avoidance for standard use rifles, unless you anticipate taking your rifle on a boat and are concerned about the optic still performing if it is submerged in water and you can still rescue the rifle.
Gas Purged Optic Tubes
Another element of preventing the buildup of wetness inside of the rifle optic 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 altered by temp shifts and pressure differences from the outdoor environment which may possibly enable water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
