What You Need to Know About Rifle Scopes
Rifle scopes permit you to specifically aim a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through magnification by using a set of lenses within the scope. The scope’s positioning can be adjusted to account for varied natural elements like wind speed and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based on the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the target. Many modern rifle optics have around eleven parts which are arranged internally and on the exterior of the optic. These optic pieces consist of the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other parts. See all eleven parts of a rifle optical system.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the optimal type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Scopes
First focal plane optics (FFP) feature the reticle ahead of the zoom lens. This induces the reticle to increase in size based upon the amount of zoom being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non amplified 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 using 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are minimal
- Experienced shooters who understand their aim point “hold over” and also “lead” equations for their firearm
- Shooters who do not mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. This induces the reticle to remain at the very same size in relation to the amount of zoom being used. The outcome is that the reticle measurements alter based upon the magnification employed to shoot over greater distances because the reticle markings present various increments which change with the magnification level. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular kinds of scopes are beneficial for:
- Long distance types of shooting where shooters have more time to make ballistic computations
- Shooting where most shots take place within shorter ranges and spaces
- Shooters who want a clearer optic picture with less space taken up by the larger sized FFP reticle
Details on Rifle Optic Magnification
The quantity of scope zoom you need on your optic depends on the form of shooting you would like to do. Nearly every kind of rifle optic supplies some degree of magnification. The volume of zoom a scope delivers is established by the size, thickness, and curvatures of the lens glass inside of the rifle scope. The zoom of the optic is the “power” of the scope. This denotes what the shooter is looking at through the scope is amplified times the power element of what can generally be seen by human eyes.
Info on Single Power Lens Rifle Glass
A single power rifle scope or optic will have a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust given that it is set from the factory.
About Variable Power Lens Optics
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom level in a configuration like 2-10×32. These numbers suggest the zoom of the scope could be set in between 2x and 10x power. This always includes the powers in-between 2 and 10. The power adjustment is accomplished by working with the power ring component of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Optics
Here are some suggested scope power settings and the distances where they may be efficiently used. High power rifle scope glass will not be as beneficial as lower magnification scopes since too much magnification can be a bad thing. The same idea relates to extended ranges where the shooter needs sufficient power to see exactly where to properly aim the rifle.
Optic Lens Coating
All modern-day rifle optic and scope lenses are coated. There are different types and qualities of glass coatings. When shopping for high end rifle optics and scope setups, Lens finish can be a significant component of a rifle. The lenses are among the most key pieces of the glass since they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses safeguards the lens surface area and also helps with anti glare from excess daylight and color recognition.
Info on Optic Lens Coatings – HD Versus ED
Some rifle glass suppliers also use “HD” or high-def glass finishings that take advantage of different procedures, elements, rare earth compounds, and polarizations to draw out different color ranges and viewable target definition through lenses. This HD finishing is commonly used with greater density glass which decreases light’s chance to refract through the lens glass. Some scope brands use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be noticeable around items with well defined outlines as light hits the item from various angles.
Single Finishing Versus Multi-Coating
Various optic lenses can also have different coverings used to them. All lenses typically have at least some type of treatment or coating applied to them before being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing 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 designer and the amount you spent paying for it. The scope’s maker and cost are indications of the lens quality.
Some scope manufacturers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Details on Anti-water Finish
Water on an optic’s lens does not support retaining a clear sight picture through an optic whatsoever. Lots of top of the line or high-end scope makers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the surface of the Steiner optic lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Optic Mounting Alternatives
Mounting options for scopes come in a few options. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually come in quick release versions which use toss levers which enable rifle shooters to rapidly install and remove the scope.
Hex Key Rifle Scope Rings
Basic, clamp-on style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use two independent rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are manufactured for long distance accuracy shooting. This kind of scope mount is effective for rifles which are in need of a resilient, hard use mount which will not change despite just how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should have for a specialized optics setup on a reach out and touch someone scouting or hard target interdiction rifle that will almost never need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount screws to keep the hex screw threads from wiggling out after they are installed tightly in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly detach a scope and attach it to a different rifle. Several scopes can even be switched out if they all use a compatible style mount. These types of mounts come in handy for long guns which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between multiple rifles.
Info Around Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can spoil a day of shooting and your costly optic by inducing fogging and making residue inside of the scope’s tube. Many optics prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof. Normally, these water-resistant optics can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of wetness avoidance for common use rifles for hunting and sporting purposes, unless you intend on taking your rifle on a boat and are concerned about the scope still working if it goes over the side and you can still salvage the gun.
About Rifle Glass Tube Gas Purging
Another element of preventing the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the scope is less impacted by temperature changes and pressure differences from the external environment which may possibly enable water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
