Scope Facts
Rifle scopes permit you to exactly align a rifle at different targets by lining up your eye with the target at range. They do this through zoom by employing a series of lenses inside the scope. The scope’s alignment can be dialed in to take into account various natural considerations like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes have around 11 parts which are arranged within and externally on the scope. These scope parts consist of the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other components. See all eleven parts of optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane an optic has identifies where the reticle or crosshair lies in connection with the scopes magnifying adjustments. It simply suggests the reticle is located behind or in front of the magnification lens of the scope. Picking the very best sort of rifle scope depends on what form of shooting you anticipate undertaking.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are small
- Experienced shooters who know their target “hold over” and “lead” relationships for their firearms
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle to the rear of the magnifying lens. This causes the reticle to remain at the exact same dimensions relative to the quantity of magnification being used. The result is that the reticle dimensions adapt based on the magnification used to shoot over lengthier distances since the reticle markings present various increments which differ with the zoom level. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These particular types of optics are convenient for:
- Far away styles of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots occur within shorter distances and ranges
- Shooters who desire a clearer optic picture with less space used up by the larger sized FFP reticle
Magnification for Glass
The measure of scope magnification you need depends upon the form of shooting you choose to do. Almost every kind of rifle optic supplies some level of zoom. The amount of zoom a scope offers is determined by the dimension, thickness, and curves of the lens glass inside of the rifle optic. The zoom of the scope is the “power” of the glass. This signifies what the shooter is looking at through the scope is amplified times the power aspect of what can generally be seen by human eyes.
Single Power Lens Scopes
A single power rifle scope will have a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not fluctuate given that it is a fixed power optic.
Info About Adjustable Power Lens Glass
Variable power rifle scopes have adjustable power. It will list the magnification degree in a format like 2-10×32. These numbers suggest the zoom of the scope can be set in between 2x and 10x power. This always includes the power levels in-between 2 and 10. The power shift is accomplished by working with the power ring component of the scope near the back of the scope by the eye bell.
Optic Power Level and Ranges
Here are some recommended scope power settings and the ranges where they may be efficiently used. Highly magnified rifle scope glass will not be as useful as lower magnification level scopes considering too much zoom can be a negative aspect depending on your shooting distance. The exact same idea relates to longer distances where the shooter needs adequate power to see precisely where to properly aim the rifle.
Scope Lens Coating
All modern rifle scope lenses are layered. There are different types and qualities of glass lens finishings. Lens finishing is an essential aspect of a rifle when thinking of high end rifle optics and scope equipment. The lenses are one of the most vital parts of the optic given that they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses offers protection to the lens surface and also improves anti glare from refracted daylight and color exposure.
HD Versus ED Lenses
Some scope producers also use “HD” or high-definition lens coverings which use different techniques, elements, polarizations, and chemicals to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
What to Know About Single Coating Versus Multi-Coating
Various scope lenses can also have different coatings applied to them. All lenses typically have at least some kind of treatment or finish applied to them before they are used in a rifle scope or optic. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It must have a finish applied to it so that the lens will be optimally functional in many types of environments, degrees of light (full VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it. The scope’s maker and cost are signs of the lens quality.
Some scope manufacturers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This suggests the lens has had numerous treatments applied to them. If a lens receives numerous treatments, it can establish that a producer is taking several steps to fight various environmental aspects like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This additionally doesn’t always imply the multi-coated lens is much better than a single coated lens. Being “much better” depends upon the producer’s lens treatment innovation and the quality of glass used in creating the rifle scope.
Anti-water Finish for Scopes
Water on an optical lens doesn’t support retaining a clear sight picture through a scope whatsoever. Numerous top of the line or premium optic producers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the surface area of the Steiner optic lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Choices for Mounting Glass on Firearms
Mounting solutions for scopes are available in a couple of options. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also generally can be found in quick release versions which use manual levers which allow rifle operators to rapidly install and dismount the scopes.
Hex Key Rifle Optic Ring Mounting Solutions
Standard, clamp style mounting scope rings use hex head screws to install to the flattop style Picatinny scope mount rails on the tops of rifles. These types of scope mounts use a pair of detached rings to support the scope, and are normally made from 7075 T6 billet aluminum which are manufactured for long distance precision shooting. This kind of scope mount is great for rifle systems which need to have a durable, hard use mount which will not change regardless of just how much the scope is moved about or jarring the rifle takes. These are the design of mounts you should get for a specialized scope system on a long distance hunting or competition long gun which will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on screws to keep the hex screw threads from wiggling out after they are mounted safely in place. An example of these mounting rings are the 30mm style from the Vortex Optics company. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle before reattaching it to a different rifle. Numerous 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 swap out the optic from the rifle for protecting the scope, or for optics which are used between several rifles.
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day on the range and your pricey optic by resulting in fogging and producing residue within the scope tube. Many optics prevent moisture from getting in the optical tube with a series of sealing O-rings which are waterproof. Typically, these water resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture content prevention for basic use rifles, unless you plan on taking your rifle sailing and are concerned about the optic still functioning if it goes over the side and you can still retrieve the gun.
Scope Gas Purging
Another element of preventing the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the scope is less affected by temperature shifts and pressure distinctions from the external environment which may potentially allow water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
