All About Rifle Glass
Rifle scopes permit you to specifically align a rifle at various targets by lining up your eye with the target over a range. They do this through magnification by making use of a series of lenses inside the scope. The scope’s positioning can be dialed in for consideration of separate natural elements like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based on the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of modern rifle scopes and optics have around 11 parts which are arranged internally and externally on the scope. These parts include the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other parts. Learn about the eleven parts of rifle glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the best type of rifle glass is based around what type of shooting you plan on doing.
Info About First Focal Plane Scopes
First focal plane glass (FFP) include the reticle ahead of the magnifying lens. This causes the reticle to increase in size based on the amount of zoom being used. The outcome is that the reticle measurements are the same at the enhanced distance as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are minor
- Experienced shooters who know their aim point “hold over” plus “lead” equations for their firearm
- Shooters who do not mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) feature 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 measurement.
- Far away styles of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots take place within much shorter ranges and proximities
- Shooters who select a clearer optic sight picture without area taken up by the larger size FFP reticle
Rifle Scope Zoom
The quantity of scope zoom you need on your scope is based on the kind of shooting you desire to do. Virtually every style of rifle glass provides some amount of zoom. The amount of zoom a scope offers is determined by the dimension, thickness, and curves of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope. This implies what the shooter is aiming at through the scope is amplified times the power element of what can generally be seen by human eyes.
About Single Power Lens Rifle Scopes
A single power rifle scope and optic comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not fluctuate considering that it is a fixed power scope.
Info About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom degree in a configuration such as 2-10×32. These numbers indicate the magnification of the scope could be changed in between 2x and 10x power. This also incorporates the power levels in-between 2 and 10. The power manipulation is achieved utilizing the power ring part of the scope near the back of the scope by the eye bell piece.
Power and Range
Here are some recommended scope power settings and the ranges where they can be successfully used. Always remember that higher power scopes and optics will not be as practical as lower magnification level optics and scopes because excessive magnification can be a detractor. The same relates to extended ranges where the shooter needs increased power to see where to best aim the rifle.
Info on Glass Lens Covering
All modern-day rifle optic and scope lenses are layered. There are different types and qualities of coverings. When looking at luxury rifle optics and scope units, Lens finish can be an essential element of a rifle. The glass lenses are among the most key parts of the glass considering that they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses shields the lens surface area and helps with anti glare from refracted direct sunlight and color perception.
ED Versus HD Scopes
Some rifle scope companies even use “HD” or high-def lense coverings that apply different procedures, elements, polarizations, and chemical applications to enhance a wide range of color ranges and viewable definition through the lens. This high-def finish is normally used with more costly, high density lens glass which drops light’s ability to refract by means of the lens glass. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration may be visible over things with defined shapes as light hits the object from particular angles.
About Single Finishing Versus Multi-Coating
Different optic lenses can also have various finishes applied to them. All lenses usually have at least some kind of treatment or finishing applied to them prior to being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It needs to have a coating placed on it so that it will be efficiently usable in lots of kinds of environments, degrees of sunlight (full VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope company and the amount you spent paying for it. Both are indications of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are covered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Scope Lens Coating
Water on a lens does not help with keeping a clear sight picture through a scope at all. Many top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish which is water repellent.
Alternatives for Installing Rifle Scopes on Long Guns
Mounting solutions for scopes come in a couple of choices. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically come in quick release versions which use manual levers which enable rifle shooters to rapidly mount and remove the glass.
Hex Key Optic Ring Mounting Solutions
Standard, 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 are designed for long range accuracy shooting. This type of scope mount is great for rifles which require a durable, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Scope Rings
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 even be switched out if they all use a similar design mount. These types of mounts are convenient for rifle platforms which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between multiple rifles.
Info Around Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your pricey optic by bringing about fogging and developing residue inside of the scope tube. Most scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another part of avoiding the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the scope is less altered by condition changes and pressure variations from the outdoor environment which may potentially allow water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
