Rifle Glass Info
Rifle scopes permit you to specifically align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnification by employing a series of lenses within the scope. The scope’s alignment can be adapted to account for many environmental elements like wind speed and elevation increases to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based on the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes have around eleven parts which are located inside and outside of the optic. These parts include the rifle scope’s body, lenses, elevation turrets, objective focus rings, and other parts. Learn about the eleven parts of optics.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the optimal type of rifle scope is based on what type of shooting you plan on doing.
Info About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the level of magnification being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non amplified range. For example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the very same tick at one hundred yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are marginal
- Experienced shooters who understand their target “hold over” and “lead” ratios for their rifles
- Shooters who don’t mind the reticle is bigger and uses up more visual sight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the magnification 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.
- Far away forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots occur within shorter distances and ranges
- Shooters who desire a clearer optic sight picture without room used up by the larger size FFP reticle
Details on Rifle Scope Magnification
The measure of scope zoom you need on your glass is based on the type of shooting you want to do. Pretty much every kind of rifle scope delivers some amount of zoom. The level of magnification a scope supplies is determined by the dimension, thickness, and curves of the lenses inside of the rifle scope. The magnification 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 aspect of what can typically be seen by human eyes.
Single Power Lens Rifle Scopes
A single power rifle scope and optic will have a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust because it is a fixed power scope.
Variable Power Lens Rifle Optic Details
Variable power rifle scopes can be adjusted between magnification power levels. These types of scopes will list the magnification level in a configuration such as 2-10×32. These numbers imply the magnification of the scope could be changed in between 2x and 10x power. This additionally includes the power levels in-between 2 and 10. The power shift is accomplished by employing the power ring part of the scope near the back of the scope by the eye bell piece.
Power Levels and Range
Here are some suggested scope power settings and the distances where they could be successfully used. High power rifle scope glass will not be as beneficial as lower magnification scopes given that too much magnification can be a negative aspect depending on your shooting distance. The same idea applies to longer ranges where the shooter needs to have sufficient power to see exactly where to best aim the rifle.
Lens Covering for Rifle Optics
All modern-day rifle scope lenses are layered. There are different types and qualities of lens coverings. When thinking about high end rifle scope units, Lens finishing can be a critical component of a rifle. The glass lenses are among the most critical components of the scope since they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses safeguards the lens exterior and improves anti glare from excess sunrays and color exposure.
About Rifle Optic Lens Coatings – HD Versus ED
Some scope makers likewise use “HD” or high-definition lens coverings which use various techniques, polarizations, chemicals, and components to draw out various 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.
Details on Single Finish Versus Multi-Coating
Various optic lenses can also have various coatings applied to them. All lenses usually have at least some type of treatment or coating used to them before being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and the amount you spent on it. Both are indicators of the lens quality.
Some scope producers also make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Anti-water Scope Lens Finishing
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Lots of top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic anti-water covering.
Choices for Mounting Rifle Glass on Firearms
Mounting approaches for scopes are available in a couple of choices. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually are made in quick release variations which use throw levers which permit rifle shooters to rapidly install and remove the optics.
Hex Key Rifle Scope Ring Mounts
Basic, clamp-on design mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on rifles. These kinds of scope mounts use two individual rings to support the scope, and are normally made from 7075 T6 billet aluminum which are developed for far away accuracy shooting. This form of scope mount is good for rifle systems which need to have a resilient, hard use mount which will not shift despite just how much the scope is moved about or jarring the rifle takes. These are the design of mounts you should get for a specialized scope system on a far away scouting or sniper competition rifle that will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the mount’s screws to keep the hex screws from wiggling out after they are mounted tightly in position. An example of these mounting rings are the 30mm type from the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Glass Rings
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. Several scopes can also be swapped out if they all use a complementary style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining accuracy. These kinds of mounts come in beneficial for rifles which are hauled around a lot, to remove the glass from the rifle for protection, or for aiming systems which are adopted in between numerous rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle optic can destroy a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. A lot of scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
About Rifle Scope Tube Gas Purging
Another element of preventing the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the optic is less affected by temperature alterations and pressure differences from the external environment which may potentially permit water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
