Information About Scopes
Rifle scopes allow you to precisely aim a rifle at different targets by lining up your eye with the target at range. They do this through magnifying the target using a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of various ecological things like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the intended target. Many modern-day rifle scopes and optics have around 11 parts which are found inside and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, modification dials, objective focus rings, and other components. Learn about the eleven parts of glass.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has identifies where the reticle or crosshair is located in relation to the scopes magnification. It simply indicates the reticle is located behind or before the magnification lens of the optic. Looking for the most reliable style of rifle optic depends on what type of shooting or hunting you intend on doing.
First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where estimations are minimal
- Experienced shooters who know their aim point “hold over” plus “lead” equations for their long guns
- Shooters who do not mind the reticle is bigger and requires more visual sight space than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle behind the magnification lens. 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.
- Far away types of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots occur within much shorter spaces and ranges
- Shooters who choose a clearer optic sight picture with less space taken up by the bigger FFP reticle
Ins and Outs of Optic Zoom
The quantity of scope zoom you need on your scope depends upon the kind of shooting you intend to do. Just about every style of rifle optic gives some amount of magnification. The volume of zoom a scope offers is determined by the size, density, and curves of the lenses inside of the rifle optic. The magnification level of the scope is the “power” of the scope. This suggests what the shooter is checking out through the scope is amplified times the power factor of what can usually be seen by human eyes.
Fixed Power Lens Optics
A single power rifle optic comes with a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not adjust considering that it is a fixed power optic.
Adjustable Power Lens Scope Facts
Variable power rifle scopes use variable power levels. The power adjustment is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Scope Power Level and Ranges
Here are some advised scope power settings and the distances where they may be effectively used. Consider that higher magnification optics will not be as effective as lower magnification level scope and optics because increased magnification can be a bad thing. The same applies to longer ranges where the shooter needs sufficient power to see exactly where to best aim the rifle.
About Rifle Glass Lens Finishes
All modern rifle scope lenses are coated. There are different types and qualities of glass coverings. When thinking about high end rifle scope setups, Lens finish can be an important component of defining the capability of the rifle. The glass lenses are one of the most essential components of the optic as they are what your eye looks through while sighting a rifle in on the point of impact. The finishing on the lenses shields the lens surface and even helps with anti glare capabilities from refracted daylight and color presence.
HD Versus ED Lenses
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use different processes, polarizations, chemicals, and elements to draw out separate colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Covering Versus Multi-Coating for Optics
Different optic lenses can even have different coverings applied to them. All lenses generally have at least some type of treatment or covering applied to them before 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 finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently functional in many types of environments, degrees of light (full VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope manufacturer and just how much you spent for it. Both the make and cost are signs of the lens quality.
Some scope manufacturers similarly make it a point to define if their optic lenses are coated or “multi” coated. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Anti-water Covering for Rifle Scopes
Water on a scope lens doesn’t help with maintaining a clear sight picture through an optic in any way. Many top of the line and high-end optic producers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the exterior surfaces of the Steiner optic lens so the water particles can not bind to it or develop surface tension. The result is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Optic Mounting Options
Mounting approaches for scopes come in a couple of options. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also usually come in quick release versions which use manual levers which allow rifle operators to quickly install and remove the scope.
Hex Key Optic Ring Mounts
Basic, clamp-on design mounting optic rings use hex head screws to position to the flattop style Picatinny scope mount rails on rifles. These kinds of scope mounts use double individual rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are manufactured for far away precision shooting. This kind of scope mount is good for rifles which require a durable, hard use mount which will not change no matter just how much the scope is moved or jarring the rifle takes. These are the type of mounts you really want to have for a dedicated optics system on a long distance scouting or competitors firearm that will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to prevent the hex screw threads from wiggling out after they are mounted safely in place. An example of these mounting rings are the 30mm style made by Vortex Optics. The set normally costs around $200 USD
Rifle Optic Mounts 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 before reattaching it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible style mount. These types of mounts come in handy for rifle platforms which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between several rifles or are situationally focused.
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle glass can ruin a day on the range and your costly optic by triggering fogging and producing residue within the scope’s tube. Most scopes protect against wetness from getting in the scope tube with a series of sealing O-rings which are waterproof. Generally, these water resistant optics can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture prevention for basic use rifles for hunting and sporting purposes, unless you anticipate taking your rifle sailing and are worried about the optic still performing if it goes overboard and you can still salvage the rifle.
Gas Purged Optic Tubes
Another component of avoiding the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the glass is less influenced by temp changes and pressure variations from the external environment which may potentially allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
