Rifle scopes allow you to specifically align a rifle at different targets by aligning your eye with the target over a range. They do this through magnifying the target by using a series of lenses inside the scope. The scope’s alignment can be adapted to take into account numerous natural factors like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle optics have about eleven parts which are located inside and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other components. Learn about the eleven parts of glass.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the optimal type of rifle glass is based around what type of shooting you plan to do.
First Focal Plane Scope Facts
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are low
- Experienced shooters who recognize their aim point “hold over” as well as “lead” correlations for their weapon
- Shooters who do not mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick.
- Long distance styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots take place within much shorter ranges and proximities
- Shooters who prefer a clearer optic sight picture with less room taken up by the enlarged FFP reticle
The quantity of scope magnification you need on your glass depends on the style of shooting you plan to do. Just about every style of rifle optic gives some degree of zoom. The quantity of zoom a scope delivers is identified by the dimension, thickness, and curves of the lens glass within the rifle scope. The magnifying level of the scope is the “power” of the opic. This implies what the shooter is aiming at through the scope is amplified times the power element of what can usually be seen by human eyes.
Single Power Lens Rifle Optics
A single power rifle scope or optic comes with a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not adjust given that it is a set power scope.
Adjustable Power Lens Scope Facts
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom degree in a format such as 2-10×32. These numbers suggest the magnification of the scope could be set between 2x and 10x power. This additionally incorporates the powers in-between 2 and 10. The power modification is accomplished by employing the power ring component of the scope near the rear of the scope by the eye bell.
Rifle Glass Power Level and Ranges
Here are some advised scope power levels and the distances where they could be successfully used. Consider that high magnification optics will not be as efficient as lower powered optics since increased magnification can be a negative thing in certain situations. The same idea relates to extended distances where the shooter needs to have adequate power to see precisely where to properly aim the rifle at the target.
About Optic Lens Coverings
All contemporary rifle scope lenses are covered in special coatings. There are different types and qualities of glass finishings. Lens coating is an essential element of a rifle when thinking of high end rifle optics and targeting units. The lenses are among the most key pieces of the glass considering they are what your eye looks through while sighting a rifle in on the point of impact. The finishing on the lenses safeguards the lens surface area and also improves anti glare capabilities from excess light and color profiles.
HD Versus ED Lenses
Some rifle scope manufacturers additionally use “HD” or high-def lens coatings which apply various processes, components, rare earth compounds, and polarizations to extract different color ranges and viewable target definition through the lens. This high-definition finishing is often used with higher density lens glass which drops light’s opportunity to refract by means of the lens glass. Some scope manufacturers use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration can be obvious around items with hard edges and shapes as light hits the item from certain angles.
Single Glass Lens Finishing Versus Multi-Coating
Various optic lenses can even have various finishes applied to them. All lenses generally have at least some kind of treatment or covering applied to them before they are used in a rifle scope or optic. This is due to the fact that the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It needs to have a covering put on it so that it will be efficiently functional in many types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope designer and how much you spent on it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are coated or “multi” coated. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in developing the rifle scope.
Hydrophobic Optic Lens Finishing
Water on a scope’s lens doesn’t assist with maintaining a clear sight picture through a scope at all. Many top of the line and premium scope manufacturers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the surface of the Steiner scope lens so the H2O molecules can not bind to it or create surface tension. The result is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Scope Installation Options
Mounting approaches for scopes are available in a few choices. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually are made in quick release versions which use throw levers which permit rifle shooters to rapidly mount and remove the glass.
Hex Key Rifle Optic Ring Mounts
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long range accuracy shooting. This type of scope install is perfect for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and connect it to a different rifle. Several scopes can also be swapped out if they all use a similar style mount. These types of mounts are convenient for rifle platforms which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between numerous rifles.
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle scope can destroy a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. Most scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Optic Tubes
Another element of avoiding the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the scope is less influenced by temp changes and pressure distinctions from the outdoor environment which could potentially allow 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.
