What You Need to Know About Rifle Scopes
Rifle scopes allow you to precisely aim a rifle at various targets by aligning your eye with the target over a range. They do this through zoom by using a set of lenses within the scope. The scope’s alignment can be adapted to account for various natural things like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters 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 target. Many modern rifle optics have about eleven parts which are located inside and externally on the scope body. These scope parts include the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other components. See all eleven parts of a rifle scope.
About Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Finding the optimal type of rifle optic is based on what type of shooting you plan on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who understand their aim point “hold over” and “lead” correlations for their weapon
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. This causes the reticle to stay at the same size in connection with the quantity of zoom being used. The end result is that the reticle dimensions adjust based on the zoom chosen to shoot over lengthier distances since the markings present distinct 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 reticle measurement. These particular kinds of optics work for:
- Far away forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots take place within shorter ranges and distances
- Shooters who want a clearer optic picture without space taken up by the larger size FFP reticle
Details on Optic Zoom
The level of scope magnification you require is based on the kind of shooting you choose to do. Just about every kind of rifle optic supplies some level of magnification. The amount of zoom a scope offers is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnifying level of the optic is the “power” of the glass. This means what the shooter is aiming at through the scope is magnified times the power element of what can typically be seen by human eyes.
About Fixed Single Power Lens Rifle Optics
A single power rifle scope and optic will have 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 magnification of this type of scope can not change given that it is a set power scope.
Variable Power Lens Glass
Variable power rifle scopes use enhanced power. The power adjustment is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Rifle Optics
Here are some suggested scope powers and the distances where they can be efficiently used. Remember that higher magnification optics will not be as effective as lower powered optics and scopes due to the fact that excessive magnification can be a detractor. The same concept applies to longer ranges where the shooter needs to have sufficient power to see precisely where to best aim the rifle at the target.
Optic Lens Covering
All cutting-edge rifle optic lenses are coated. Lens finishing is a crucial aspect of a shooting system when thinking about high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope producers also use “HD” or high-definition lens finishes which use different techniques, components, polarizations, and chemicals to draw out different colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
About Single Finish Versus Multi-Coating
Different optic lenses can likewise have different coverings used to them. All lenses typically have at least some type of treatment or finish applied to them before being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope developer and how much money you spent for it. The scope’s maker and cost are indicators of the lens quality.
Some scope producers similarly make it a point to specify if their optic lenses are coated or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
Rifle Optic Lens Hydrophobic Covering
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic anti-water coating.
Choices for Mounting Scopes on Firearms
Mounting options for scopes can be found in a couple of options. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release variations which use toss levers which enable rifle operators to quickly install and remove the scope.
Optic Mounting Solutions with Hex Key Rings
Standard, clamp-on design mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These styles of scope mounts use two detached rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are made for long distance precision shooting. This form of scope mount is good for rifle systems which need to have a resilient, hard use mount which will not move regardless of how much the scope is moved about or jarring the rifle takes. These are the design of mounts you really want to have for a dedicated scope system on a reach out and touch someone scouting or hard target interdiction firearm which will rarely need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the mount’s screws to keep the hex screw threads from wiggling out after they are installed firmly in place. An example of these rings are the 30mm style made by the Vortex Optics company. The set generally costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be switched out if they all use a similar style mount. These types of mounts are convenient for rifle platforms which are transferred a lot, to swap out the optic from the rifle for protection, or for optics which are used between several rifles.
About Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle glass can destroy a day on the range and your costly optic by causing fogging and creating residue within the scope’s tube. A lot of scopes prevent moisture from entering the optical tube with a series of sealing O-rings which are water resistant. Normally, these water resistant scopes can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of wetness avoidance for conventional use rifles, unless you anticipate taking your rifle on a boat and are worried about the scope still performing if it is submerged in water and you can still rescue the gun.
Info Around Rifle Optic Tube Gas Purging
Another part of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is currently taken up by the gas, the glass is less impacted by temp shifts and pressure distinctions from the outside environment which might possibly enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
