Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnification using a series of lenses within the scope. The scope’s positioning can be adjusted for consideration of various ecological elements like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will land based on the sight picture you are seeing with the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes and optics have around eleven parts which are arranged within and outside of the scope. These optic pieces include the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the finest type of rifle optic is based on what type of shooting you plan on doing.
First Focal Plane Optic Details
First focal plane glass (FFP) include the reticle in front of the zoom lens. This triggers the reticle to increase in size based upon the amount of magnification being used. The outcome is that the reticle measurements are the same at the enhanced range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the identical tick at 100 yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are small
- Experienced shooters who have an idea for their target “hold over” plus “lead” relationships for their firearms
- Shooters who do not mind the reticle is bigger and occupies more visual sight room than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) feature the reticle behind the magnification lens. This causes the reticle to remain at the very same scale relative to the volume of zoom being used. The end result is that the reticle dimensions shift based on the zoom employed to shoot over longer ranges due to the fact that the markings represent various increments which can vary with the magnification level. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular kinds of scopes are convenient for:
- Far away types of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots occur within much shorter ranges and proximities
- Shooters who select a clearer optic sight picture with less area taken up by the enlarged FFP reticle
The amount of scope magnification you need on your scope depends on the kind of shooting you would like to do. Virtually every style of rifle optic delivers some level of zoom. The quantity of zoom a scope offers is identified by the size, density, and curvatures of the lens glass within the rifle scope. The zoom of the optic is the “power” of the scope. This signifies what the shooter is observing through the scope is amplified times the power factor of what can normally be seen by human eyes.
About Fixed Power Lens Glass
A single power rifle scope uses a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not change considering that it is a set power scope.
About Variable Power Lens Scopes
Variable power rifle scopes use variable power levels. The power change is accomplished by the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Scopes
Here are some recommended scope power levels and the distances where they can be efficiently used. High power optics will not be as beneficial as lower powered optics because too much magnification can be a negative aspect depending on your shooting distance. The exact same concept relates to longer distances where the shooter needs adequate power to see precisely where to properly aim the rifle at the target.
Rifle Scope Lens Finish
All modern-day rifle scope lenses are covered in special coatings. There are different types and qualities of lens finishes. Lens finish can be a crucial element of a rifle’s setup when considering high end rifle optics and targeting systems. The glass lenses are among the most crucial components of the glass considering that they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses offers protection to the lens surface area and also helps with anti glare from excess daylight and color perception.
Details on Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens coverings which use different processes, elements, polarizations, and chemicals to draw out separate colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
What to Know About Single Covering Versus Multi-Coating
Different scope lenses can also have different finishes applied to them. All lenses normally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic. This is due to the fact that the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in numerous kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope producer and how much money you paid for it. The scope’s maker and cost are signs of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Hydrophobic Covering for Rifle Optics
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Numerous top of the line and military grade scope makers will coat their lenses with a hydrophobic or hydrophilic coating.
Alternatives for Mounting Rifle Glass on Firearms
Mounting approaches for scopes come in a few choices. There are the basic scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also usually come in quick release versions which use toss levers which permit rifle operators to quickly install and remove the optics.
Hex Key Scope Rings
Standard, clamp-on type mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These kinds of scope mounts use two separate rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are manufactured for far away accuracy shooting. This kind of scope mount is great for rifles which need to have a durable, unfailing mount which will not move regardless of 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 setup on a reach out and touch someone hunting or sniper competition long gun that will rarely need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to keep the hex screws from wiggling out after they are installed safely in position. An example of these rings are the 30mm type from the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle. If they all use a similar design mount, multiple scopes can often be switched in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten tightly to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining accuracy. These types of mounts are useful and practical for shooting platforms which are transferred between vehicles a lot, to take off the glass from the rifle for protection, or for optics which are employed between a number of rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle scope can ruin a day of shooting and your expensive optic by triggering fogging and developing residue inside of the scope tube. The majority of scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
About Rifle Scope Tube Gas Purging
Another element of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the scope is less impacted by temperature changes and pressure distinctions from the outdoor environment which might potentially allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
