Information Glass
Rifle scopes enable you to specifically aim a rifle at various targets by lining up your eye with the target over a range. They do this through zoom by using a set of lenses inside the scope. The scope’s positioning can be adapted to account for varied ecological considerations like wind and elevation increases or decreases to make up 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 seeing using the optic as you line up the scope’s crosshair or reticle with the target. The majority of modern rifle scopes have around 11 parts which are arranged within and outside of the scope body. These scope parts consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of scopes.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane a scope has identifies where the reticle or crosshair lies in relation to the scopes magnifying adjustments. It simply indicates the reticle is situated behind or before the magnifying lens of the scope. Picking the most effective type of rifle scope is dependent on what sort of shooting you plan on doing.
First Focal Plane Scopes
First focal plane scopes (FFP) feature the reticle ahead of the magnifying lens. This induces the reticle to increase in size based upon the extent of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the identical tick at one hundred yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who recognize their target “hold over” plus “lead” correlations for their long gun
- Shooters who don’t mind the reticle is bigger and occupies more visual sight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane glass (SFP) feature the reticle behind the magnification lens. This triggers the reticle to remain at the very same dimensions relative to the quantity of zoom being used. The effect is that the reticle dimensions shift based upon the magnification chosen to shoot over longer distances because the reticle markings represent distinct increments which differ with the zoom. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These types of scopes are handy for:
- Far away kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots happen within shorter proximities and ranges
- Shooters who select a clearer optic picture without room used up by the larger size FFP reticle
Ins and Outs of Glass Zoom
The level of scope magnification you need on your optic depends on the type of shooting you would like to do. Pretty much every kind of rifle optic supplies some amount of magnification. The amount of magnification a scope offers is identified by the diameter, density, and curves of the lens glass within the rifle optic. The magnification level of the optic is the “power” of the opic. This suggests what the shooter is looking at through the scope is amplified times the power factor of what can typically be seen by human eyes.
Fixed Power Lens Rifle Optic Facts
A single power rifle scope or optic comes with a magnification number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not adjust given that it is a fixed power scope.
About Adjustable Power Lens Scopes
Variable power rifle scopes use variable power levels. The power modification is performed using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Scopes
Here are some suggested scope power levels and the distances where they could be efficiently used. Keep in mind that higher power scopes and optics will not be as efficient as lower powered optics and scopes since increased magnification can be a bad thing. The same idea relates to extended distances where the shooter needs increased power to see precisely where to best aim the rifle at the target.
Info on Lens Coverings
All state-of-the-art rifle glass lenses are layered. Lens finish can be a crucial aspect of a shooting platform when buying high end rifle optics and scope systems.
Details on Lens Coatings – HD Versus ED
Some optic suppliers also use “HD” or high-def glass finishes that take advantage of various processes, rare earth compounds, polarizations, and aspects to enhance various color ranges and viewable definition through the lens. This HD coating is often used with higher density glass which lowers light’s capability to refract through the lens glass. Some scope suppliers use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration may be obvious around objects with defined shapes as light hits the item from particular angles.
Single Covering Versus Multi-Coating
Various scope lenses can also have various finishings applied to them. All lenses generally have at least some kind of treatment or finishing applied to them before being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It must have a finish placed on it so that it will be optimally functional in numerous types of environments, degrees of sunshine (full light VS shade), 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 safeguard 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 upon the scope manufacturer and the amount you spent for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Hydrophobic Optic Lens Finish
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic coating.
Alternatives for Installing Scopes on Long Guns
Installing options for scopes come in a few choices. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various types of mounts also normally are made in quick release versions which use throw levers which permit rifle shooters to rapidly install and dismount the scope.
Hex Key Scope Ring Mounts
Normal, 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 different rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope mount is wonderful for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and attach it to a different rifle. Several scopes can also be swapped out if they all use a compatible style mount. These types of mounts are handy for long guns which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between multiple rifles.
What to Know About Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. The majority of scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Glass Tubes
Another element of preventing the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the optic is less affected by temperature changes and pressure variations from the outside environment which might potentially enable water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
