Facts About Rifle Scopes
Rifle scopes enable you to precisely aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnification by utilizing a set of lenses inside the scope. The scope’s positioning can be adjusted to take into account various environmental considerations like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are seeing with the optic as you line up the scope’s crosshair or reticle with the target. A lot of contemporary rifle scopes and optics have around eleven parts which are located internally and externally on the scope body. These scope parts include the rifle scope’s body, lenses, windage dials, focus rings, and other elements. See all eleven parts of an optic.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Finding the finest type of rifle scope depends on what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where estimations are very little
- Experienced shooters who know their target “hold over” as well as “lead” correlations for their weapon
- Shooters who don’t mind the reticle is bigger and takes up more visual sight area than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. This causes the reticle to stay at the same size relative to the level of magnification being used. The result is that the reticle dimensions change based on the magnification applied to shoot over greater distances given that the reticle measurements represent various increments which change with the magnification. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These particular styles of glass work for:
- Long distance styles 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 select a clearer optic picture without space taken up by the larger size FFP reticle
The extent of scope zoom you need is based on the style of shooting you would like to do. Virtually every type of rifle optic delivers some degree of magnification. The volume of zoom a scope gives is established by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the glass. This implies what the shooter is aiming at through the scope is amplified times the power aspect of what can typically be seen by human eyes.
Fixed Power Lens Rifle Optic Info
A single power rifle optic or scope will have a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not adjust because it is a fixed power scope.
Variable Power Lens Scopes
Variable power rifle scopes have adjustable power. It will list the zoom degree in a configuration like 2-10×32. These numbers imply the magnification of the scope can be changed in between 2x and 10x power. This always includes the powers in-between 2 and 10. The power adaptation is achieved using the power ring component of the scope near the rear of the scope by the eye bell.
The Power and Range of Glass
Here are some advised scope power settings and the ranges where they can be successfully used. Highly magnified scopes will not be as beneficial as lower powered glass considering too much zoom can be a bad thing. The same idea goes for extended distances where the shooter needs sufficient power to see exactly where to properly aim the rifle at the target.
Rifle Glass Lens Finishing
All state-of-the-art rifle scope lenses are coated. Lens coating can be a vital aspect of a shooting platform when considering high end rifle optics and scope systems.
HD Versus ED Lens Coatings
Some scope brands likewise use “HD” or high-definition lens finishings which use different methods, components, polarizations, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Rifle Scope Lens Single Finishing Versus Multi-Coating
Different optic lenses can also have different coverings used to them. All lenses usually have at least some type of treatment or finish used to them before being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it.
Some scope manufacturers likewise make it a point to define if their optic lenses are layered or “multi” coated. This indicates the lens has multiple treatments applied to the surfaces. If a lens gets multiple treatments, it can show that a producer is taking numerous steps to fight various natural factors like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This also does not necessarily mean the multi-coated lens will perform much better than a single layered lens. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle optic.
Anti-water Finishing for Optics
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Many top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Alternatives for Installing Scopes on Firearms
Mounting approaches for scopes can be found in a couple of choices. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also typically are made in quick release versions which use toss levers which enable rifle shooters to rapidly mount and remove the glass.
Hex Key Scope Ring Mounting Solutions
Standard, 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 two 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 install is great for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Scope Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly detach a scope from a rifle and reattach it to a different rifle. If they all use a comparable design mount, several scopes can often be swapped out. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top type 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 maintaining accuracy. These kinds of mounts come in convenient for rifles which are transported a lot, to remove the scope glass from the rifle for protection, or for optics which are adopted between several rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle scope can ruin a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. A lot of scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
About Optic Tube Gas Purging
Another part of avoiding the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is already taken up by the gas, the glass is less impacted by temperature level shifts and pressure distinctions from the outdoor environment which could potentially permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
