What You Need to Know About Rifle Glass
Rifle scopes enable you to specifically align a rifle at different targets by lining up your eye with the target over a distance. They do this through magnifying the target by making use of a series of lenses inside the scope. The scope’s alignment can be dialed in for consideration of numerous environmental elements like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the target. Most modern-day rifle scopes have about 11 parts which are found inside and externally on the scope body. These parts include the rifle scope’s body, lenses, windage dials, focus rings, and other components. See all eleven parts of a rifle optical system.
About Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane an optic has identifies where the reticle or crosshair is located in connection with the optic’s magnification. It literally indicates the reticle is situated behind or in front of the magnifying lens of the scope. Picking out the most suitable kind of rifle glass depends upon what kind of hunting or shooting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who understand their aim point “hold over” and “lead” relationships for their firearms
- Shooters who do not mind the reticle is bigger and uses up more visual eyesight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle behind the zoom lens. This causes the reticle to remain at the very same scale in connection with the level of magnification being used. The result is that the reticle dimensions adjust based upon the zoom chosen to shoot over lengthier ranges since the reticle measurements represent different increments which change with the zoom level. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement. These types of glass work for:
- Long distance forms of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and spaces
- Shooters who prefer a clearer optic sight picture without area taken up by the bigger FFP reticle
Glass Zoom
The quantity of zoom a scope provides is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Optic Info
A single power rifle scope or optic 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 scope can not adjust given that it is set from the factory.
Variable Power Lens Optics
Variable power rifle scopes can be modified between magnified settings. The power modification is performed using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some advised scope power levels and the ranges where they may be effectively used. Always remember that high power scopes will not be as efficient as lower magnification level glass because too much zoom can be a bad thing. The very same idea applies to longer distances where the shooter needs increased power to see exactly where to best aim the rifle.
Lens Finish for Glass
All cutting-edge rifle glass lenses are covered. Lens finish is a significant aspect of a rifle system when thinking about high end rifle optics and scope systems.
HD Versus ED Lens Coatings
Some optic manufacturers even use “HD” or high-definition lense coatings that take advantage of different procedures, rare earth compounds, aspects, and polarizations to enhance different colors and viewable target visibility through lenses. This high-definition coating is normally used with more costly high density glass which brings down light’s ability to refract through the lens glass. Some scope corporations use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious over items with hard edges and outlines as light hits the object from specific angles.
About Single Finish Versus Multi-Coating
Different optic lenses can likewise have various finishes used to them. All lenses typically have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope designer and how much money you spent on it. Both the manufacturer and amount are indications of the lens quality.
Some scope producers likewise make it a point to define if their optic lenses are coated or “multi” coated. This means the lens has had several treatments applied to the surfaces. If a lens receives several treatments, it can show that a company is taking multiple actions to combat various environmental elements like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This additionally doesn’t always imply the multi-coated lens is better than a single coated lens. Being “much better” depends on the maker’s lens treatment techniques and the quality of glass used in developing the rifle scope.
Anti-water Lens Coatings
Water on a scope lens doesn’t support maintaining a clear sight picture through an optic in any way. Many top of the line or premium optic manufacturers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the exterior of the Steiner glass lens so the water particles can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Scope Mounting Choices
Mounting options for scopes come in a few options. There are the standard scope rings which are individually 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 allow rifle operators to rapidly install and dismount the scopes.
Hex Key Glass Rings
Basic, clamp-on type mounting scope rings use hex head screws to install to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use double separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are designed for far away precision shooting. This form of scope mount is ideal for rifle systems which need to have a resilient, hard use mount which will not shift no matter how much the scope is moved or jarring the rifle takes. These are the design of mounts you should get for a faithful scope system on a reach out and touch someone hunting or competitors long gun that will almost never need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to protect against the hex screw threads from wiggling out after they are mounted firmly in place. An example of these mounting rings are the 30mm style made by Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. If they all use a similar style mount, multiple scopes can also be switched on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach solidly to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining accuracy. These types of mounts are useful and beneficial for rifles which are shipped a lot, to remove the glass from the rifle for protection, or for optics which are chosen for use in between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can spoil a day on the range and your costly optic by resulting in fogging and making residue within the scope’s tube. A lot of optics protect against moisture from entering the optical tube with a system of sealing O-rings which are waterproof. Typically, these water-resistant scopes can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of wetness prevention for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are concerned about the optic still working if it goes over the side and you can still rescue the firearm.
Gas Purged Rifle Scope Tubes
Another element of avoiding the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the scope is less impacted by condition shifts and pressure differences from the outdoor environment which could potentially permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
