Optic Information
Rifle scopes allow you to specifically align a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnifying the target using a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of different ecological things like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern rifle optics have around 11 parts which are arranged internally and on the exterior of the optic. These parts include the rifle scope’s body, lenses, elevation dials or turrets, objective 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 scopes. The style of focal plane a scope has identifies where the reticle or crosshair is located in regard to the optic’s zoom. It literally indicates the reticle is behind or in front of the magnification lens of the optic. Choosing the most desired type of rifle glass depends upon what form of shooting you intend on doing.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This causes the reticle to increase in size based on the level of zoom being used. The result is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are marginal
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” ratios for their rifles
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight room than a SFP reticle
Second Focal Plane Optics
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.
- Long distance styles of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots happen within shorter spaces and ranges
- Shooters who choose a clearer optic picture without area taken up by the bigger FFP reticle
Rifle Optic Zoom
The quantity of zoom a scope offers is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Scopes
A single power rifle scope uses a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not change given that it is a fixed power optic.
About Variable Power Lens Rifle Scopes
Variable power rifle scopes can be tweaked between magnified levels. The power adjustment is accomplished by the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some advised scope powers and the distances where they may be effectively used. Always remember that higher magnification optics will not be as effective as lower powered optics because excessive zoom can be a detractor. The same concept goes for longer ranges where the shooter needs enough power to see where to best aim the rifle.
Details on Lens Finishing
All cutting-edge rifle optic lenses are layered. Lens finishing can be an essential aspect of a rifle when purchasing high end rifle optics and scope setups.
About Lens Coatings – HD Versus ED
Some scope brands likewise use “HD” or high-definition lens finishes which use different processes, elements, chemicals, and polarizations to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finish Versus Multi-Coating for Rifle Scopes
Different scope lenses can even have various coverings applied to them. All lenses normally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in many kinds of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are layered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in building the rifle scope.
Anti-water Coating for Rifle Optics
Water on a scope lens does not improve retaining a clear sight picture through a scope at all. Numerous top of the line or high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the exterior of the Steiner optic lens so the H2O molecules can not bind to it or create surface tension. The result is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Options for Mounting Rifle Scopes on Long Guns
Mounting approaches for scopes can be found in a couple of choices. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These various types of mounts also usually can be found in quick release variations which use manual levers which permit rifle shooters to rapidly mount and dismount the optics.
Hex Key Scope Ring Mounts
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope mount is perfect for rifles which need a long lasting, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle. A wide range of scopes can also be swapped out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping the original sighting settings. These kinds of mounts are useful and convenient for shooting platforms which are moved a lot, to take off the glass from the rifle for protection, or for optics which are employed between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle optic can destroy a day on the range and your expensive optic by inducing fogging and developing residue within the scope’s tube. Many scopes prevent humidity from entering the scope tube with a series of sealing O-rings which are water resistant. Generally, these water-resistant scopes can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture content prevention for standard use rifles for hunting and sporting purposes, unless you anticipate taking your rifle sailing and are concerned about the scope still functioning if it falls overboard and you can still recover the rifle.
Scope Gas Purging
Another part of avoiding the buildup of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the optic is less affected by temperature changes and pressure differences from the external environment which could potentially enable water vapor to permeate 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.
