Rifle Optic Info
Rifle scopes allow you to specifically align a rifle at various targets by lining up your eye with the target over a range. They accomplish this through zoom by utilizing a set of lenses inside the scope. The scope’s positioning can be dialed in for the consideration of many ecological factors like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the intended target. Many modern-day rifle scopes and optics have about 11 parts which are arranged inside and on the exterior of the scope. These parts consist of the rifle scope’s body, lenses, modification dials, objective focus rings, and other components. See all eleven parts of an optic.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane a scope has decides where the reticle or crosshair lies in regard to the scopes magnification. It simply suggests the reticle is behind or before the magnification lens of the scope. Selecting the very best form of rifle glass is based upon what kind of hunting or shooting you plan on doing.
First Focal Plane Scope Details
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who know their aim point “hold over” and “lead” equations for their long gun
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle behind 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 measurement.
- Long distance kinds of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots take place within shorter proximities and ranges
- Shooters who prefer a clearer optic picture without area taken up by the larger sized FFP reticle
About Glass Magnification
The measure of scope magnification you require is based on the kind of shooting you want to do. Virtually every type of rifle scope gives some degree of magnification. The quantity of magnification a scope offers is determined by the diameter, density, and curvatures of the lens glass within the rifle optic. The magnifying level of the scope is the “power” of the glass. This suggests what the shooter is checking out through the scope is amplified times the power factor of what can usually be seen by human eyes.
Fixed Power Lens Rifle Glass Info
A single power rifle optic and scope will have a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate considering that it is a fixed power optic.
Variable Power Lens Rifle Glass Info
Variable power rifle scopes can be modified between magnified settings. The power change is handled by using the power ring part of the scope near the rear of the scope by the eye bell.
Optic Power Level and Ranges
Here are some recommended scope power levels and the distances where they can be effectively used. Bear in mind that higher power glass will not be as practical as lower magnification level glass due to the fact that increased zoom can be a negative thing in certain situations. The same idea relates to extended ranges where the shooter needs sufficient power to see where to properly aim the rifle.
Rifle Glass Lens Finishing
All modern-day rifle optic lenses are covered. Lens covering can be an essential element of a shooting platform when considering high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope producers likewise use “HD” or high-definition lens coverings which use various techniques, chemicals, aspects, and polarizations to draw out different 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.
Glass Lens Single Coating Versus Multi-Coating
Various scope lenses can also have various coverings applied to them. All lenses normally have at least some kind of treatment or covering applied to them before they are used in a rifle scope or optic assembly. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It must have a finishing placed on it so that the lens will be efficiently usable in many types of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope makers similarly make it a point to specify if their optic lenses are layered or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in building the rifle scope.
Anti-water Coating for Optics
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic coating which is water repellent.
Glass Installation Choices
Mounting solutions for scopes come in a couple of options. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also generally come in quick release versions which use throw levers which allow rifle shooters to quickly mount and dismount the optics.
Glass Mounts with Hex Key Rings
Standard, clamp-on type mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use a pair of independent rings to support the scope, and are made from 7075 T6 billet aluminum which are manufactured for far away accuracy shooting. This type of scope mount is effective for rifles which need to have a resilient, hard use mount which will not change no matter how much the scope is moved or abuse the rifle takes. These are the design of mounts you really want to have for a devoted optics system on a long distance hunting or interdiction firearm which will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount screws to stop the hex screw threads from backing out after they are installed tightly in position. An example of these mounting rings are the 30mm style from Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible design mount. These types of mounts come in handy for long guns which are carried a lot, to remove the optic from the rifle for protection, or for optics which are used between numerous rifles.
About Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your pricey optic by bringing about fogging and producing residue inside of the scope tube. Most scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Rifle Scope Gas Purging
Another component of preventing the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the optic is less impacted by temperature alterations and pressure distinctions from the outdoor environment which may potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
