Facts About 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 zoom by employing a set of lenses within the scope. The scope’s alignment can be dialed in for the consideration of varied ecological things like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Most modern rifle scopes and optics have around eleven parts which are arranged within and on the exterior of the scope body. These parts include the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other components. See all eleven parts of scopes.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the best type of rifle optic is based on what type of shooting you plan on doing.
Info on First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are minimal
- Experienced shooters who have an idea for their aim point “hold over” and “lead” correlations for their long guns
- Shooters who do not mind the reticle is bigger and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. This triggers the reticle to stay at the exact same scale relative to the volume of magnification being used. The result is that the reticle measurements evolve based on the magnification employed to shoot over greater distances because the reticle markings represent distinct increments which vary with the zoom level. In the FFP example 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 varieties of glass work for:
- Far away forms of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots happen within much shorter spaces and ranges
- Shooters who want a clearer optic picture without area taken up by the enlarged FFP reticle
Details on Optic Magnification
The level of scope zoom you need on your glass depends on the form of shooting you wish to do. Just about every kind of rifle scope gives some amount of magnification. The volume of magnification a scope provides is established by the dimension, density, and curvatures of the lens glass inside of the rifle scope. The magnification of the optic is the “power” of the opic. This denotes what the shooter is checking out through the scope is amplified times the power element of what can usually be seen by human eyes.
Fixed Single Power Lens Rifle Scope Facts
A single power rifle scope or optic will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not change because it is set from the factory.
Info About Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will list the magnification degree in a format such as 2-10×32. These numbers mean the zoom of the scope can be changed between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power adaptation is achieved by working with the power ring part of the scope near the back of the scope by the eye bell piece.
Rifle Scope Power Level and Range Correlation
Here are some suggested scope power settings and the distances where they may be successfully used. Keep in mind that higher power optics will not be as practical as lower powered scope and optics because increased zoom can be a negative thing in certain situations. The exact same idea goes for extended ranges where the shooter needs to have adequate power to see exactly where to best aim the rifle.
Details on Lens Coating
All contemporary rifle glass lenses are covered. Lens covering can be a crucial element of a shooting platform when looking at high end rifle optics and scope setups.
Details on Lens Coatings – HD Versus ED
Some scope brands likewise use “HD” or high-definition lens coverings which use different methods, chemicals, polarizations, and aspects to draw out various colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Rifle Scope Lens Single Covering Versus Multi-Coating
Different optic lenses can likewise have various coverings used to them. All lenses typically 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 safeguard the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are coated or “multi” coated. This suggests the lens has several treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can indicate that a maker is taking multiple actions to fight various natural factors like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This additionally doesn’t necessarily indicate the multi-coated lens will perform better than a single layered lens. Being “better” is dependent on the producer’s lens treatment innovation and the quality of materials used in developing the rifle optic.
Details on Anti-water Covering
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic coating.
Alternatives for Mounting Rifle Optics on Long Guns
Installing options for scopes come in a couple of options. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also usually are made in quick release versions which use manual levers which enable rifle operators to quickly mount and remove the scopes.
Scope Mounting Solutions with Hex Key Rings
Standard, clamp style mounting optic rings use hex head screws to install to the flattop style Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use double detached rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are made for far away accuracy shooting. This kind of scope mount is effective for rifles which are in need of a durable, hard use mount which will not change despite how much the scope is moved about or jarring the rifle takes. These are the style of mounts you really want to have for a dedicated optics system on a long distance hunting or competition long gun that will hardly ever need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used to protect against the hex screws from wiggling out after they are installed securely in place. An example of these mounting rings are the 30mm type made by the Vortex Optics brand. The set generally costs around $200 USD
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle. If they all use a comparable style mount, several scopes can often be swapped out. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect nicely to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving the original sighting settings. These kinds of mounts are useful and beneficial for rifles which are transported a lot, to take off the scope from the rifle for protection, or for sight systems which are used between several rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It usually costs around $250 USD
Details on Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your costly optic by causing fogging and generating residue within the scope tube. Most scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are waterproof. Generally, these scopes can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient wetness avoidance for standard use rifles, unless you intend on taking your rifle boating and are worried about the optic still working if it is submerged in water and you can still recover the gun.
Rifle Glass Gas Purging
Another element of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the optic is less affected by condition shifts and pressure distinctions from the external environment which could potentially enable water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
