Rifle Scope Facts
Rifle scopes permit you to specifically aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnifying the target using a set of lenses within the scope. The scope’s positioning can be dialed in for consideration of various ecological considerations like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will land based upon the sight picture you are seeing via the scope as you align the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes and optics have about eleven parts which are located within and on the exterior of the optic. These parts include the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
About Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the optimal type of rifle scope depends on what type of shooting you plan on doing.
Info About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who know their target “hold over” and also “lead” equations for their firearms
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight room than a SFP reticle
Second Focal Plane Scope Details
Second focal plane optics (SFP) feature the reticle behind 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 measurement.
- Far away kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots occur within much shorter distances and ranges
- Shooters who like a clearer optic sight picture without space used up by the larger sized FFP reticle
About Optic Magnification
The extent of scope zoom you need on your scope depends on the form of shooting you choose to do. Nearly every type of rifle scope delivers some amount of magnification. The amount of zoom a scope supplies is established by the diameter, thickness, and curvatures of the lenses inside of the rifle optic. The magnifying level of the optic is the “power” of the opic. This means what the shooter is looking at through the scope is amplified times the power factor of what can typically be seen by human eyes.
About Fixed Power Lens Rifle Scopes
A single power rifle optic or scope will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not fluctuate given that it is a set power scope.
Variable Power Lens Scope Facts
Variable power rifle scopes have adjustable power. It will note the zoom level in a format like 2-10×32. These numbers suggest the zoom of the scope can be adjusted between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power modification is achieved by employing the power ring component of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range Correlation of Scopes
Here are some advised scope power settings and the ranges where they could be successfully used. Bear in mind that higher power optics will not be as practical as lower powered glass because too much zoom can be a bad thing. The same concept relates to longer ranges where the shooter needs to have enough power to see precisely where to properly aim the rifle.
Details on Lens Coating
All contemporary rifle scope lenses are covered. Lens covering can be an important aspect of a rifle when looking at high end rifle optics and scope setups.
HD Versus ED Lenses
Some rifle glass producers additionally use “HD” or high-definition glass coverings that make the most of various procedures, rare earth compounds, aspects, and polarizations to draw out a wide range of colors and viewable target visibility through the lens. This HD coating is commonly used with more costly high density glass which reduces light’s ability to refract through the lens glass. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration can be obvious around things with hard edges and shapes as light hits the object from various angles.
What to Know About Single Covering Versus Multi-Coating
Various optic lenses can likewise have different coatings used to them. All lenses typically have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” coated. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
Hydrophobic Lens Coating
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Numerous top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic coating.
Alternatives for Installing Optics on Long Guns
Installing solutions for scopes can be found in a few choices. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually are made in quick release versions which use toss levers which allow rifle operators to quickly mount and remove the glass.
Hex Key Glass Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style 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 developed for long distance accuracy shooting. This type of scope mount is fine for rifles which require a durable, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be switched out if they all use a complementary designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely 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 back on the rifle while maintaining the original sighting settings. These types of mounts come in handy for shooting platforms which are carried a lot, to remove the glass from the rifle for protection, or for aiming systems which are utilized in between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It normally costs around $250 USD
About Scope Tube Sealing and Gas Purging
Moisture inside your rifle glass can ruin a day on the range and your pricey optic by resulting in fogging and making residue within the scope’s tube. The majority of optics prevent humidity from entering the optical tube with a series of sealing O-rings which are water resistant. Generally, these water resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture avoidance for common use rifles, unless you plan on taking your rifle boating and are worried about the scope still working if it goes over the side and you can still find the gun.
Gas Purged Rifle Scope Tubes
Another element of avoiding the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the glass is less influenced by condition alterations and pressure distinctions from the outdoor environment which could possibly permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
