What You Need to Know About Rifle Glass
Rifle scopes enable you to precisely align a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through magnification using a set of lenses inside the scope. The scope’s alignment can be dialed in for consideration of numerous natural aspects like wind speed and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle scopes and optics have about 11 parts which are found internally and externally on the scope body. These scope parts consist of the rifle scope’s body, lenses, modification turrets, objective focus rings, and other parts. See all eleven parts of optics.
About Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the best type of rifle glass depends on what type of shooting you plan to do.
Info About First Focal Plane Glass
First focal plane scopes (FFP) include the reticle before the magnifying lens. This causes the reticle to increase in size based upon the amount of zoom being used. The result is that the reticle measurements are the same at the magnified range as they are at the non amplified distance. For example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are minimal
- Experienced shooters who know their target “hold over” plus “lead” ratios for their weapon
- Shooters who do not mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away forms of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots take place within much shorter spaces and ranges
- Shooters who select a clearer optic picture without area taken up by the bigger FFP reticle
Rifle Optic Zoom
The quantity of scope magnification you require depends on the kind of shooting you choose to do. Pretty much every kind of rifle glass offers some amount of zoom. The quantity of magnification a scope offers is determined by the size, density, and curvatures of the lenses inside of the rifle optic. The magnification level of the scope is the “power” of the opic. This suggests what the shooter is checking out through the scope is amplified times the power aspect of what can typically be seen by human eyes.
About Single Power Lens Rifle Glass
A single power rifle scope and optic uses a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not fluctuate because it is a fixed power optic.
Variable Power Lens Optic Facts
Variable power rifle scopes use variable power levels. The power change is accomplished by the power ring part of the scope near the back of the scope by the eye bell.
Glass Power Level and Ranges
Here are some advised scope power levels and the ranges where they can be successfully used. Bear in mind that high magnification optics and scopes will not be as effective as lower magnification level glass because increased zoom can be a bad thing. The exact same concept relates to extended distances where the shooter needs to have increased power to see precisely where to properly aim the rifle.
About Rifle Glass Lens Coverings
All contemporary rifle scope and optic lenses are coated. There are different types and qualities of lens coatings. Lens covering can be a crucial element of a rifle’s setup when thinking of high end rifle optics and scope units. The glass lenses are one of the most critical parts of the scope given that they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses offers protection to the lens surface area and helps with anti glare capabilities from excess natural light and color perception.
About Scope Lens Coatings – HD Versus ED
Some scope manufacturers likewise use “HD” or high-definition lens finishings which use different processes, aspects, chemicals, and polarizations to draw out a wide range of colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
About Single Covering Versus Multi-Coating
Various optic lenses can also have different finishes applied to them. All lenses generally have at least some kind of treatment or finishing applied to them before they are used in a rifle scope or optic assembly. 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 requires a coating to be applied to it so that it will be optimally usable in many kinds of environments, degrees of sunshine (full VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Hydrophobic Lens Finishes
Water on a scope lens does not improve retaining a clear sight picture through a scope whatsoever. Numerous top of the line and premium optic makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the exterior surfaces of the Steiner scope lens so the H2O particles can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to keep a clear, water free sight picture.
Alternatives for Installing Glass on Long Guns
Mounting approaches for scopes can be found in a few choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also usually can be found in quick release versions which use throw levers which enable rifle operators to rapidly mount and remove the glass.
Glass Mounting Solutions with Hex Key Rings
Basic, clamp-on design mounting optic rings use hex head screws to position to the flattop design Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use double independent rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance precision shooting. This kind of scope mount is exceptional for rifles which are in need of a long lasting, hard use mount which will not shift despite how much the scope is moved or jarring the rifle takes. These are the style of mounts you should have for a dedicated optics setup on a long distance hunting or sniper competition long gun that will pretty much never need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the screws to stop the hex screw threads from backing out after they are mounted safely in position. An example of these rings are the 30mm type made by the Vortex Optics company. The set generally costs around $200 USD
Quick-Release Cantilever Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle. If they all use a similar design mount, multiple scopes can often be switched out on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining accuracy. These types of mounts are useful and beneficial for shooting platforms which are moved around a lot, to remove the scope from the rifle for protection, or for aiming systems which are employed in between numerous rifles. An example of this mount style is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle optic can destroy a day of shooting and your pricey optic by bringing about fogging and producing 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.
Details on Rifle Glass Tube Gas Purging
Another element of preventing the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the glass is less altered by condition changes and pressure differences from the outside environment which may potentially permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
