Optic Facts
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target over a range. They accomplish this through magnification using a set of lenses inside the scope. The scope’s alignment can be adjusted to take into account many ecological things like wind speed and elevation to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing with the optic as you align the scope’s crosshair or reticle with the target. Many modern-day rifle scopes and optics have about eleven parts which are arranged inside and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials or turrets, objective focus rings, and other components. See all eleven parts of an optic.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the best type of rifle optic is based around what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are marginal
- Experienced shooters who understand their target “hold over” as well as “lead” ratios for their firearms
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight area than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the zoom lens. This causes the reticle to stay at the same size relative to the amount of magnification being used. The outcome is that the reticle measurements alter based upon the magnification employed to shoot over longer ranges since the markings present different increments which differ with the zoom level. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These particular varieties of glass work for:
- Far away kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots occur within shorter ranges and proximities
- Shooters who select a clearer optic sight picture with less area taken up by the bigger FFP reticle
Rifle Scope Zoom
The extent of scope zoom you need on your scope depends upon the form of shooting you like to do. Almost every type of rifle optic delivers some amount of magnification. The level of zoom a scope offers is established by the dimension, thickness, and curves of the lens glass within the rifle scope. The magnifying level of the optic is the “power” of the scope. This implies what the shooter is observing through the scope is amplified times the power factor of what can usually be seen by human eyes.
Fixed Power Lens Rifle Glass
A single power rifle optic or scope comes with a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust because it is set from the factory.
Variable Power Lens Scopes
Variable power rifle scopes have adjustable power. It will list the magnification amount in a format like 2-10×32. These numbers imply the zoom of the scope could be set in between 2x and 10x power. This additionally incorporates 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 rear of the scope by the eye bell piece.
Scope Power Level and Ranges
Here are some recommended scope powers and the distances where they may be efficiently used. Always remember that higher power optics will not be as efficient as lower magnification level optics since too much magnification can be a detractor. The same idea applies to longer ranges where the shooter needs enough power to see precisely where to properly aim the rifle.
About Rifle Glass Lens Coatings
All modern-day rifle optic and scope lenses are coated. Lens covering is a significant element of a rifle system when looking into high end rifle optics and scope equipment.
About Lens Coatings – HD Versus ED
Some scope producers likewise use “HD” or high-definition lens coatings which use different methods, aspects, polarizations, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Optics
Various scope lenses can also have different finishes applied to them. All lenses usually have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a finish applied to it so that it will be efficiently functional in numerous kinds of environments, degrees of sunlight (full VS shade), and other shooting conditions.
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 lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope developer and how much money you spent for it. Both the make and cost are signs of the lens quality.
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 manufacturer’s lens treatment technology and the quality of products used in building the rifle scope.
Hydrophobic Lens Coverings
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic coating.
Options for Mounting Rifle Glass on Firearms
Mounting approaches for scopes come in a couple of choices. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release variations which use throw levers which enable rifle operators to rapidly mount and remove the optics.
Hex Key Rifle Scope Rings
Basic, clamp-on style mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on rifles. These styles of scope mounts use a pair of individual rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are created for far away precision shooting. This type of scope mount is effective for rifle systems which require a durable, unfailing mount which will not shift no matter how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a devoted scope setup on a far away hunting or hard target interdiction long gun which will hardly ever need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to protect against the hex screws from wiggling out after they are mounted securely in position. An example of these rings are the 30mm type made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be switched out if they all use a compatible style mount. These types of mounts come in handy for rifles which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are used in between several rifles or are situationally focused.
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can wreck a day of shooting and your pricey optic by causing fogging and developing residue within the scope tube. The majority of scopes prevent humidity from going into the scope tube with a series of sealing O-rings which are waterproof. Normally, these water resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture content prevention for conventional use rifles for hunting and sporting purposes, unless you intend on taking your rifle on boats and are worried about the optic still working if it falls overboard and you can still salvage the gun.
Rifle Glass Gas Purging
Another element of avoiding the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the glass is less affected by temperature level changes and pressure differences from the outside environment which may possibly enable 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 look for.
