Rifle scopes allow you to exactly aim a rifle at various targets by lining up your eye with the target at range. They do this through magnification by using a series of lenses within the scope. The scope’s alignment can be dialed in to account for various ecological elements like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based upon the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes and optics have around 11 parts which are found within and externally on the optic. These scope parts include the rifle scope’s body, lenses, modification turrets, focus rings, and other elements. See all eleven parts of scopes.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the optimal type of rifle scope is based around what type of shooting you plan to do.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This triggers the reticle to increase in size based on the extent of magnification being used. The outcome is that the reticle measurements are the same at the magnified distance as they are at the non magnified range. As an example, one tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are marginal
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” equations for their rifles
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle to the rear of 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 reticle measurement.
- Far away kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots take place within shorter ranges and distances
- Shooters who desire a clearer optic sight picture without space used up by the larger size FFP reticle
Rifle Scope Zoom
The level of scope magnification you require depends upon the form of shooting you desire to do. Virtually every kind of rifle optic delivers some level of magnification. The volume of zoom a scope supplies is determined by the size, thickness, and curves of the lenses within the rifle scope. The magnifying level of the optic is the “power” of the opic. This suggests what the shooter is observing through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Fixed Power Lens Glass Info
A single power rifle optic uses a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not change because it is a set power scope.
Variable Power Lens Rifle Optics
Variable power rifle scopes use enhanced power. The power change is accomplished using the power ring part of the scope near the rear of the scope by the eye bell.
Optic Power and Range Correlation
Here are some advised scope power levels and the distances where they may be effectively used. Highly magnified rifle scope glass will not be as efficient as lower magnification scopes considering too much zoom can be a bad thing. The same applies to extended ranges where the shooter needs to have sufficient power to see where to properly aim the rifle at the target.
Info on Lens Coverings
All modern rifle scope and optic lenses are coated. There are different types and qualities of glass finishes. When considering high end rifle scope units, Lens coating can be a crucial aspect of a rifle. The lenses are one of the most essential components of the glass considering that they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses safeguards the lens exterior as well as improves anti glare from refracted sunrays and color visibility.
ED Versus HD Optics
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use different techniques, chemicals, aspects, and polarizations to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Finish Versus Multi-Coating
Different optic lenses can also have various finishings applied to them. All lenses generally have at least some type of treatment or covering applied to them before being used in a rifle scope or optic assembly. 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 generally a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope developer and how much you spent for it. Both the make and cost are signs of the lens quality.
Some scope manufacturers similarly make it a point to specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of products used in developing the rifle scope.
Hydrophobic Lens Finish
Water on a lens does not help with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade optic companies will coat their lenses with a hydrophobic or hydrophilic finish.
Options for Mounting Rifle Scopes on Firearms
Mounting solutions for scopes can be found in a few options. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually are made in quick release versions which use toss levers which permit rifle shooters to rapidly install and remove the optics.
Hex Key Optic Rings
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 two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long distance precision shooting. This type of scope mount is excellent for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly detach a scope from a rifle and reattach it to a different rifle. Several scopes can also be swapped out if they all use a similar designed mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top type 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 retaining the original sighting settings. These types of mounts are useful and handy for rifles which are transferred a lot, to remove the scope from the rifle for protection, or for scopes which are adopted in between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It usually costs around $250 USD
Info on Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your costly optic by bringing about fogging and producing residue inside of the scope tube. Most scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Info Around Rifle Optic Tube Gas Purging
Another element of avoiding the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the optic is less influenced by climate alterations and pressure differences from the outside environment which may possibly permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
