Information About Rifle Scopes
Rifle scopes enable you to exactly align a rifle at various targets by lining up your eye with the target at range. They do this through magnification by utilizing a set of lenses within the scope. The scope’s positioning can be dialed in to take into account separate natural things like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based on the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the target. Most modern rifle scopes have around eleven parts which are arranged internally and externally on the scope. These parts consist of the rifle scope’s body, lenses, elevation turrets or dials, focus rings, and other elements. Learn about the eleven parts of glass.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane an optic has decides where the reticle or crosshair lies in relation to the optic’s magnification. It simply suggests the reticle is situated behind or before the magnifying lens of the scope. Picking the best sort of rifle optic is based upon what sort of shooting or hunting you anticipate doing.
First Focal Plane Scopes
First focal plane scopes (FFP) feature the reticle before the zoom lens. This causes the reticle to increase in size based upon the amount of zoom being used. The benefit 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 one hundred yards without “zoom” is still the very same tick at one hundred yards by using 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who know their aim point “hold over” and also “lead” correlations for their long guns
- Shooters who do not mind the reticle is bigger and takes up more visual sight room than a SFP reticle
Second Focal Plane Optics
Second focal plane glass (SFP) include the reticle to the rear of the magnifying lens. This causes the reticle to stay at the very same size in relation to the quantity of zoom being used. The outcome is that the reticle dimensions adapt based on the zoom applied to shoot over greater distances considering that the markings represent distinct increments which can vary with the magnification. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These styles of scopes are beneficial for:
- Far away kinds of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots happen within shorter proximities and ranges
- Shooters who would like a clearer optic sight picture without space taken up by the larger sized FFP reticle
Rifle Glass Zoom
The amount of zoom a scope offers is figured out by the diameter, thickness, 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 Scopes
A single power rifle scope and optic will have a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not change because it is fixed.
Adjustable Power Lens Rifle Optic Info
Variable power rifle scopes can be adjusted between magnification power levels. It will list the magnification degree in a configuration such as 2-10×32. These numbers mean the zoom of the scope can be changed between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power shift is achieved by applying the power ring component of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some suggested scope power levels and the ranges where they can be efficiently used. High power scopes will not be as beneficial as lower powered optics due to the fact that too much zoom can be a bad thing. The same idea applies to extended ranges where the shooter needs to have sufficient power to see exactly where to properly aim the rifle at the target.
Rifle Optic Lens Finishing
All modern rifle scope and optic lenses are layered. Lens covering is a vital element of a shooting system when looking at high end rifle optics and scope systems.
HD Versus ED Rifle Scope Lens Coatings
Some scope makers also use “HD” or high-definition lens coatings which use different techniques, elements, chemicals, and polarizations to draw out a wide range of colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finish Versus Multi-Coating for Rifle Optics
Different scope lenses can even have different finishes applied to them. All lenses generally have at least some kind of treatment or finishing 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 functional in numerous kinds of environments, degrees of light (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less advantageous 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 likewise make it a point to define if their optic lenses are coated or “multi” coated. This implies the lens has multiple treatments applied to the surfaces of the glass. If a lens receives multiple treatments, it can show that a company is taking multiple steps to fight various environmental elements like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This also does not always suggest the multi-coated lens is better than a single coated lens. Being “much better” is dependent on the manufacturer’s lens treatment innovation and the quality of components used in building the rifle optic.
Hydrophobic Lens Coating
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic finishing which is water repellent.
Glass Installation Options
Mounting approaches for scopes come in a couple of choices. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release variations which use toss levers which enable rifle operators to quickly mount and dismount the optics.
Hex Key Glass Ring Mounting Solutions
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount 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 is created for long range precision shooting. This type of scope install is excellent for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abused.
Rifle Glass Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly remove 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 attach securely to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping accuracy. These types of mounts come in beneficial for shooting platforms which are transferred between vehicles a lot, to remove the optic from the rifle for protection, or for optics which are chosen for use 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 Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. Many optics prevent wetness from getting in the optical tube with a system of sealing O-rings which are waterproof. Generally, these water-resistant scopes can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of humidity prevention for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle on boats and are worried about the scope still performing if it goes over the side and you can still rescue the rifle.
Gas Purged Optic Tubes
Another part of preventing the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the glass is less altered by temperature level shifts and pressure variations from the outdoor environment which may possibly allow 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.
