Rifle scopes enable you to specifically aim a rifle at various targets by aligning your eye with the target over a range. They accomplish this through magnification by making use of a series of lenses inside the scope. The scope’s positioning can be adapted for consideration of different environmental aspects like wind and elevation to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based upon the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle scopes and optics have about 11 parts which are located internally and on the exterior of the optic. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other parts. See all eleven parts of scopes.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the perfect type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who have an idea for their target “hold over” and “lead” correlations for their firearm
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
Second Focal Plane Optic Facts
Second focal plane scopes (SFP) include the reticle behind the magnifying lens. This induces the reticle to remain at the very same size in connection with the volume of zoom being used. The end result is that the reticle dimensions evolve based on the zoom employed to shoot over lengthier distances considering that the reticle markings represent distinct increments which change with the zoom level. 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 glass work for:
- Far away kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots occur within much shorter spaces and ranges
- Shooters who like a clearer optic sight picture with less room taken up by the larger sized FFP reticle
About Rifle Scope Zoom
The measure of scope zoom you need on your scope depends on the form of shooting you wish to do. Practically every style of rifle optic offers some amount of magnification. The level of magnification a scope supplies is established by the diameter, thickness, and curvatures of the lens glass within the rifle scope. The magnifying level of the scope is the “power” of the scope. This indicates what the shooter is aiming at through the scope is amplified times the power element of what can generally be seen by human eyes.
Fixed Power Lens Rifle Optics
A single power rifle optic and scope uses a zoom 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 type of optic can not adjust because it is set from the factory.
Variable Power Lens Rifle Optics
Variable power rifle scopes use enhanced power. The power adjustment is performed by the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Scopes
Here are some recommended scope power settings and the ranges where they could be successfully used. High power optics will not be as effective as lower powered glass considering that too much zoom can be a bad thing. The same idea relates to longer ranges where the shooter needs to have increased power to see where to best aim the rifle at the target.
Rifle Scope Lens Coating
All modern rifle optic and scope lenses are covered in special coatings. There are various types and qualities of glass finishes. Lens coating is an essential aspect of a rifle when looking into high-end rifle optics and scope equipment. The lenses are one of the most essential parts of the scope because they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses protects the lens exterior and even assists with anti glare from excess sunrays and color exposure.
Details on Optic Lens Coatings – HD Versus ED
Some rifle glass manufacturers even use “HD” or high-def glass finishes which apply various processes, polarizations, components, and chemicals to enhance separate colors and viewable target definition through lenses. This HD finish is often used with more costly, high density glass which decreases light’s ability to refract by means of the lens glass. Some scope manufacturers 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 or deviance which is also called color distortion or fringing. Chromatic aberration can be noticeable over things with hard edges and outlines as light hits the object from particular angles.
Single Covering Versus Multi-Coating
Various optic lenses can likewise have various coverings used to them. All lenses generally have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while decreasing 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 producer and how much you paid for it.
Some scope producers similarly make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Hydrophobic Lens Finishes
Water on an optic’s lens doesn’t assist with preserving a clear sight picture through a scope in any way. Many top of the line and premium scope manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the exterior of the Steiner scope lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Choices for Mounting Rifle Scopes on Long Guns
Mounting options for scopes can be found in a few choices. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically can be found in quick release variations which use throw levers which allow rifle shooters to rapidly install and remove the optics.
Hex Key Rifle Optic Rings
Normal, clamp design 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 often made from 7075 T6 billet aluminum which is developed for long range precision shooting. This type of scope mount is perfect for rifles which require a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly detach a scope and connect it to a different rifle. Numerous scopes can even be switched out if they all use a similar design mount. These types of mounts are convenient for rifle platforms which are transferred a lot, to swap out the optic from the rifle for protection, or for scopes which are used between several rifles.
Details on Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by triggering fogging and creating residue within the scope’s tube. A lot of scopes prevent humidity from entering the optical tube with a system of sealing O-rings which are water resistant. Generally, these scopes can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture content prevention for standard use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on boats and are worried about the scope still performing if it is submerged in water and you can still recover the rifle.
Rifle Glass Gas Purging
Another element of preventing the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the scope is less impacted by climate changes and pressure variations from the outdoor environment which might possibly permit water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
