Rifle Optic Information
Rifle scopes allow you to precisely align a rifle at various targets by aligning your eye with the target over a range. They accomplish this through magnification using a series of lenses inside the scope. The scope’s positioning can be adapted to account for different ecological aspects like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based upon the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes and optics have around 11 parts which are found internally and outside of the scope body. These parts include the rifle scope’s body, lenses, modification turrets, focus rings, and other parts. See all eleven parts of optics.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the best type of rifle scope is based around what type of shooting you plan on doing.
First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the extent of magnification being used. The benefit is that the reticle measurements are the same at the magnified 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 by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are minimal
- Experienced shooters who understand their aim point “hold over” and “lead” equations for their firearms
- Shooters who do not mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle to the rear of the zoom 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 measurement.
- Far away kinds of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who want a clearer optic picture with less room used up by the larger size FFP reticle
Optic Zoom
The quantity of zoom a scope supplies 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 Power Lens Optic Details
A single power rifle optic and scope will have 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 optic can not adjust since it is a fixed power scope.
Variable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. It will note the magnification degree in a format like 2-10×32. These numbers mean the zoom of the scope could be set in between 2x and 10x power. This also utilizes the powers in-between 2 and 10. The power adaptation is accomplished utilizing the power ring part of the scope near the back of the scope by the eye bell.
Glass Power and Ranges
Here are some advised scope power levels and the distances where they may be successfully used. Consider that higher power glass will not be as effective as lower powered glass since increased zoom can be a negative thing in certain situations. The exact same concept relates to longer ranges where the shooter needs enough power to see precisely where to best aim the rifle.
Rifle Scope Lens Finish
All modern rifle scope lenses are covered in special coatings. There are various types and qualities of glass lens coatings. When considering luxury rifle optics and scope units, Lens finish can be an essential aspect of defining the capability of the rifle. The lenses are among the most vital components of the scope due to the fact that they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses shields the lens surface area and even improves anti glare capabilities from refracted sunlight and color discernibility.
ED Versus HD Optics
Some scope manufacturers likewise use “HD” or high-definition lens coatings which use different techniques, aspects, 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” indicating extra-low dispersion glass.
Single Rifle Scope Lens Coating Versus Multi-Coating
Different optic lenses can also have various coatings 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. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely 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 light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends on the scope developer and how much you spent on it. Both the make and cost are indicators of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are covered or “multi” coated. This means the lens has had numerous treatments applied to the surfaces. If a lens receives multiple treatments, it can indicate that a producer is taking numerous actions to combat various environmental aspects like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This also does not always suggest the multi-coated lens is better than a single layered lens. Being “much better” depends on the maker’s lens treatment technology and the quality of products used in constructing the rifle scope.
Anti-water Lens Covering
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Lots of top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic finishing which is water repellent.
Optic Installation Choices
Mounting approaches for scopes are available in a couple of options. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally can be found in quick release variations which use toss levers which permit rifle shooters to rapidly mount and dismount the scope.
Hex Key Glass Ring Mounting Solutions
Basic, clamp design mounting optic rings use hex head screws to position to the flattop style Picatinny scope mounting rails on rifles. These types of scope mounts use two separate rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance precision shooting. This type of scope mount is excellent for rifle systems which need a resilient, rock solid mount which will not change regardless of how much the scope is moved or abuse the rifle takes. These are the design of mounts you really want to have for a faithful optics setup on a far away hunting or competitors long gun that will hardly ever need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the screws to stop the hex screw threads from wiggling out after they are mounted safely in place. An example of these rings are the 30mm style from Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle. Several scopes can also be switched out if they all use a complementary style mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect nicely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving precision. These kinds of mounts are useful and convenient for rifles which are transferred between vehicles a lot, to take off the optic from the rifle for protection, or for optics which are employed between several rifles. An example of this mount style is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle scope can mess up a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. The majority of scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Rifle Optic Gas Purging
Another part of preventing the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the optic is less impacted by condition alterations and pressure distinctions from the outdoor environment which may potentially permit water vapor to leak 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.
