What You Need to Know About Rifle Optics
Rifle scopes allow you to specifically align a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through magnification using a set of lenses within the scope. The scope’s positioning can be adjusted for the consideration of different natural elements like wind speed and elevation increases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the target. The majority of modern-day rifle optics have about 11 parts which are arranged internally and outside of the optic. These optic pieces consist of the rifle scope’s body, lenses, elevation dials or turrets, objective focus rings, and other components. Learn about the eleven parts of glass.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Opting for the best type of rifle scope is based on what type of shooting you plan on doing.
About First Focal Plane Scopes
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 level of magnification being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non amplified distance. For example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the same tick at 100 yards using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are small
- Experienced shooters who have an idea for their target “hold over” and “lead” relationships for their weapon
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) come with 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.
- Long distance kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots happen within shorter ranges and spaces
- Shooters who prefer a clearer optic sight picture with less space taken up by the larger sized FFP reticle
Zoom for Rifle Glass
The level of scope zoom you need on your glass depends on the sort of shooting you like to do. Virtually every kind of rifle scope offers some level of magnification. The amount of zoom a scope delivers is established by the diameter, density, and curves of the lens glass inside of the rifle scope. The magnifying level of the scope is the “power” of the glass. This indicates what the shooter is looking at through the scope is magnified times the power element of what can generally be seen by human eyes.
Fixed Single Power Lens Rifle Optics
A single power rifle optic uses a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not adjust since it is set from the factory.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes use enhanced power. The power modification is accomplished by the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some suggested scope power settings and the ranges where they could be efficiently used. Bear in mind that higher magnification optics will not be as effective as lower powered scope and optics due to the fact that increased magnification can be a negative thing in certain situations. The same concept relates to extended distances where the shooter needs increased power to see precisely where to properly aim the rifle.
Info on Glass Lens Finish
All current rifle optic lenses are covered. Lens finish can be a significant aspect of a shooting platform when looking into high end rifle optics and scope setups.
HD Versus ED Lenses
Some scope manufacturers also use “HD” or high-definition lens finishings which use various methods, elements, polarizations, and chemicals to draw out various colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Optics
Various optic lenses can likewise have different finishes applied to them. All lenses generally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can safeguard 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 coated lens depends upon the scope manufacturer and the amount you spent for it. Both are signs of the lens quality.
Some scope makers likewise make it a point to specify if their optic lenses are covered or “multi” covered. This indicates the lens has several treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can show that a manufacturer is taking several actions to combat different natural factors like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This additionally doesn’t necessarily imply the multi-coated lens will perform better than a single coated lens. Being “better” depends on the producer’s lens treatment solutions and the quality of components used in creating the rifle glass.
Anti-water Lens Covering
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic finishing.
Rifle Optic Installation Alternatives
Installing solutions for scopes are available in a couple of choices. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically can be found in quick release variations which use throw levers which enable rifle shooters to quickly install and dismount the glass.
Hex Key Scope Ring Mounts
Standard, clamp style 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 is designed for long range accuracy shooting. This type of scope mount is wonderful for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Glass Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be switched out if they all use a similar design mount. These types of mounts are handy for rifles which are carried a lot, to remove the optic from the rifle for protection, or for optics which are used in between multiple rifles.
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle scope can destroy a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. The majority of scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Optic Gas Purging
Another component of avoiding the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the scope is less altered by temperature level alterations and pressure variations from the outside environment which might possibly allow 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.
