Facts About Rifle Scopes
Rifle scopes enable you to exactly align a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through magnification by utilizing a series of lenses within the scope. The scope’s positioning can be adjusted to take into account various ecological elements like wind and elevation to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based upon the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of modern rifle optics have about 11 parts which are found internally and externally on the scope. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other parts. Learn about the eleven parts of glass.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane an optic has establishes where the reticle or crosshair is located in regard to the scopes magnification. It literally suggests the reticle is behind or ahead of the magnifying lens of the scope. Selecting the most suitable type of rifle glass is based upon what sort of hunting or shooting you anticipate undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This causes the reticle to increase in size based upon the level of magnification being used. The outcome is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the identical tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are low
- Experienced shooters who understand their target “hold over” plus “lead” relationships for their weapon
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight room than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle to the rear of the magnifying lens. This triggers the reticle to remain at the same overall size relative to the amount of magnification being used. The final result is that the reticle measurements evolve based upon the magnification used to shoot over greater distances given that the markings represent various increments which fluctuate with the zoom. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular types of optics are useful for:
- Far away kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots occur within much shorter ranges and spaces
- Shooters who select a clearer optic picture without room used up by the larger sized FFP reticle
Zoom for Rifle Optics
The amount of zoom a scope offers is figured out by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Glass
A single power rifle optic and scope comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate because it is fixed.
About Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be tweaked between magnified levels. The power change is handled by the power ring part of the scope near the back of the scope by the eye bell.
Scope Power and Ranges
Here are some recommended scope powers and the ranges where they could be effectively used. Keep in mind that high magnification scopes will not be as efficient as lower powered glass since too much zoom can be a bad thing. The same idea applies to longer distances where the shooter needs sufficient power to see exactly where to best aim the rifle at the target.
Info on Rifle Optic Lens Coatings
All modern-day rifle scope lenses are coated. Lens finish can be a vital element of a shooting system when thinking about high end rifle optics and scope systems.
HD Versus ED Lenses
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use various techniques, polarizations, components, and chemicals to draw out different colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Rifle Optic Lens Finishing 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 prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope makers similarly make it a point to specify if their optic lenses are layered or “multi” covered. Being “better” depends on the producer’s lens treatment innovation and the quality of products used in developing the rifle scope.
Anti-water Lens Coverings
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic covering.
Rifle Scope Installing Choices
Mounting approaches for scopes are available in a couple of options. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also generally come in quick release variations which use throw levers which allow rifle operators to rapidly mount and remove the scope.
Hex Key Scope Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope install is great for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be switched out if they all use a similar style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping the original sighting settings. These kinds of mounts are useful and practical for shooting platforms which are transferred a lot, to take off the scope from the rifle for protection, or for scopes which are adopted in between several rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It typically costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle glass can ruin a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope tube. Many scopes protect against wetness from going into the optical tube with a series of sealing O-rings which are waterproof. Normally, these optics can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture prevention for standard use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on your motorboat and are worried about the optic still working if it is submerged in water and you can still recover the gun.
Gas Purged Rifle Optic Tubes
Another element of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the optic is less affected by temperature level shifts and pressure distinctions from the outside environment which may potentially allow water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
