Scope Information
Rifle scopes permit you to precisely align a rifle at various targets by aligning your eye with the target at range. They do this through zoom by employing a set of lenses inside the scope. The scope’s positioning can be adjusted for consideration of many ecological elements like wind and elevation to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Most modern rifle scopes and optics have around 11 parts which are arranged inside and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, modification turrets, objective focus rings, and other elements. Learn about the eleven parts of rifle scopes.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane an optic has decides where the reticle or crosshair is located in regard to the scopes zoom. It literally indicates the reticle is located behind or ahead of the magnifying lens of the optic. Considering the most desired form of rifle optic depends upon what style of shooting 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, long distance kinds of shooting
- Shooting circumstances where calculations are minor
- Experienced shooters who recognize their aim point “hold over” plus “lead” equations for their firearms
- Shooters who do not mind the reticle is enlarged and takes up more visual sight room than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane scopes (SFP) feature the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots occur within much shorter ranges and spaces
- Shooters who select a clearer optic sight picture without room used up by the enlarged FFP reticle
Scope Magnification
The level of scope zoom you require depends upon the kind of shooting you desire to do. Almost every style of rifle glass supplies some degree of magnification. The amount of magnification a scope supplies is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle optic. The magnification of the optic is the “power” of the glass. This indicates what the shooter is looking at through the scope is magnified times the power element of what can typically be seen by human eyes.
About Fixed Power Lens Optics
A single power rifle optic and scope uses a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not fluctuate since it is fixed.
Adjustable Power Lens Rifle Scope Info
Variable power rifle scopes have adjustable power. It will list the zoom amount in a format like 2-10×32. These numbers imply the magnification of the scope can be adjusted between 2x and 10x power. This additionally includes the powers in-between 2 and 10. The power adaptation is achieved utilizing the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range Correlation of Rifle Optics
Here are some recommended scope power settings and the distances where they could be successfully used. Consider that higher magnification scopes and optics will not be as effective as lower magnification level scopes due to the fact that excessive zoom can be a bad thing. The same idea applies to extended distances where the shooter needs to have increased power to see precisely where to best aim the rifle at the target.
About Lens Covering
All cutting-edge rifle optic and scope lenses are covered. Lens finish is an essential aspect of a rifle system when thinking about high end rifle optics and scope systems.
HD Versus ED Lenses
Some rifle scope companies will also use “HD” or high-def glass finishes which apply various procedures, rare earth compounds, polarizations, and elements to enhance numerous colors and viewable target definition through the lens. This HD finish is frequently used with more costly, high density lens glass which drops light’s potential to refract through the lens glass. Some scope makers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration may be noticeable over objects with hard outlines as light hits the object from certain angles.
Info on Single Coating Versus Multi-Coating
Various optic lenses can also have various finishings used to them. All lenses typically have at least some type of treatment or coating used to them before being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” coated. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in developing the rifle scope.
Info on Hydrophobic Finishing
Water on an optic’s lens doesn’t help with retaining a clear sight picture through an optic whatsoever. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It deals with the surface of the Steiner scope lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Choices for Installing Rifle Glass on Firearms
Mounting approaches for scopes can be found in a few options. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually can be found in quick release variations which use manual levers which enable rifle shooters to quickly mount and remove the glass.
Hex Key Rifle Glass Ring Mounting Solutions
Standard, clamp-on type mounting scope rings use hex head screws to position to the flattop style Picatinny scope mounting rails on rifles. These types of scope mounts use two individual rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are designed for far away precision shooting. This form of scope mount is good for rifles which are in need of a long lasting, rock solid mount which will not change regardless of just how much the scope is moved or jarring the rifle takes. These are the design of mounts you really want to have for a dedicated optics system on a reach out and touch someone scouting or competitors firearm which will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on screws to protect against the hex screws from wiggling out after they are mounted tightly in place. An example of these rings are the 30mm style made by the Vortex Optics brand. The set normally costs around $200 USD
Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and connect it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible style mount. These types of mounts are convenient for long guns which are carried a lot, to swap out the optic from the rifle for protection, or for optics which are used in between multiple rifles or are situationally focused.
What to Know About Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle glass can destroy a day of shooting and your pricey optic by inducing fogging and creating residue within the scope tube. Most optics protect against wetness from entering the optical tube with a system of sealing O-rings which are water resistant. Usually, these water-resistant optics can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture avoidance for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle sailing and are concerned about the scope still working if it goes overboard and you can still salvage the firearm.
Optic Gas Purging
Another component of preventing the accumulation of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the scope is less altered by climate changes and pressure differences from the external environment which might potentially permit water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
