What You Need to Know About Glass
Rifle scopes permit you to precisely align a rifle at various targets by lining up your eye with the target over a range. They do this through magnification by utilizing a set of lenses inside the scope. The scope’s positioning can be adjusted to take into account numerous ecological elements like wind speed and elevation to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the intended target. Most contemporary rifle optics have about 11 parts which are located inside and externally on the scope body. These scope parts include the rifle scope’s body, lenses, elevation turrets or dials, focus rings, and other parts. See all eleven parts of a rifle scope.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the perfect type of rifle glass is based around what type of shooting you plan to do.
First Focal Plane Optic Details
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who have an idea for their target “hold over” plus “lead” ratios for their firearms
- Shooters who do not mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle behind the magnifying lens. This causes the reticle to remain at the very same dimensions in relation to the quantity of magnification being used. The end result is that the reticle measurements evolve based on the magnification applied to shoot over greater distances considering the markings represent various increments which differ with the zoom. 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 reticle measurement. These types of glass are convenient for:
- Long distance kinds of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots happen within shorter proximities and ranges
- Shooters who would like a clearer optic picture with less area taken up by the bigger FFP reticle
Magnification for Rifle Optics
The quantity of scope zoom you need on your glass depends upon the kind of shooting you would like to do. Virtually every kind of rifle optic supplies some amount of zoom. The level of zoom a scope supplies is identified by the size, thickness, and curvatures of the lens glass inside of the rifle optic. The zoom 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 typically be seen by human eyes.
Info on Fixed Single Power Lens Rifle Optics
A single power rifle scope uses a magnification 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 change considering that it is a set power scope.
Variable Power Lens Scope Info
Variable power rifle scopes can be changed between magnification power levels. These types of scopes will list the magnification level in a configuration like 2-10×32. These numbers suggest the zoom of the scope can be set in between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power adjustment is accomplished by making use of the power ring component of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range Correlation of Glass
Here are some suggested scope power levels and the ranges where they may be efficiently used. Highly magnified scopes will not be as efficient as lower magnification level optics because too much magnification can be a negative aspect depending on your shooting distance. The same idea applies to extended distances where the shooter needs to have increased power to see where to best aim the rifle.
Lens Finishing for Rifle Optics
All contemporary rifle optic lenses are coated. There are different types and qualities of glass lens coatings. Lens covering can be a crucial element of a rifle’s setup when considering high-end rifle optics and scope units. The lenses are among the most important pieces of the glass since they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses offers protection to the lens surface and even helps with anti glare capabilities from excess sunshine and color exposure.
HD Versus ED Rifle Scope Lens Coatings
Some optic makers will also use “HD” or high-definition glass finishes that use various procedures, elements, chemical substances, and polarizations to enhance a wide range of color ranges and viewable target definition through lenses. This high-definition coating is typically used with more costly high density glass which reduces light’s chance to refract through the lens glass. Some scope brands use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration may be obvious over items with hard edges and outlines as light hits the object from various angles.
Single Covering Versus Multi-Coating for Rifle Scopes
Various optic lenses can even have various coatings applied to them. All lenses normally have at least some kind of treatment or finishing applied to them before being used in a rifle scope or optic. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It must have a finishing put on it so that it will be efficiently usable in lots of kinds of environments, degrees of light (full VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends on the scope designer and how much you spent paying for it. Both the make and cost are indications of the lens quality.
Some scope producers likewise make it a point to define if their optic lenses are layered or “multi” coated. This indicates the lens has had numerous treatments applied to the surfaces of the glass. If a lens receives multiple treatments, it can indicate that a maker is taking several steps to combat different environmental factors like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This also doesn’t always indicate the multi-coated lens is much better than a single coated lens. Being “better” hinges on the maker’s lens treatment techniques and the quality of products used in developing the rifle scope.
Anti-water Lens Coverings
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Many top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic finish.
Rifle Glass Installation Alternatives
Mounting solutions for scopes are available in a couple of options. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also generally come in quick release variations which use toss levers which enable rifle shooters to quickly install and dismount the optics.
Hex Key Rifle Optic Rings
Standard, clamp design mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on the tops of rifles. These forms of scope mounts use double individual rings to support the scope, and are made from 7075 T6 billet aluminum which are manufactured for far away accuracy shooting. This form of scope mount is effective for rifles which require a durable, unfailing mount which will not shift no matter just how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should have for a specialized scope system on a reach out and touch someone scouting or sniper competition long gun which will seldom need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount screws to keep the hex screw threads from backing out after they are installed firmly in place. An example of these rings are the 30mm style made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Optic Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. If they all use a comparable design mount, multiple scopes can often be swapped on the range. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving accuracy. These types of mounts come in handy for rifles which are moved around a lot, to take off the scope from the rifle for protection, or for sight systems which are utilized between several rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It typically costs around $250 USD
Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can mess up a day of shooting and your pricey optic by triggering fogging and making residue inside of the scope tube. Most scopes prevent wetness from entering the optical tube with a system of sealing O-rings which are waterproof. Normally, these water resistant 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 more than enough humidity avoidance for standard use rifles for hunting and sporting purposes, unless you anticipate taking your rifle boating and are concerned about the optic still performing if it is submerged in water and you can still find the firearm.
Rifle Glass Gas Purging
Another element of avoiding the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the optic is less impacted by temperature changes and pressure distinctions from the external environment which may possibly enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
