What You Need to Know About Rifle Glass
Rifle scopes allow you to precisely align a rifle at different targets by lining up your eye with the target over a range. They accomplish this through zoom by making use of a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of different natural things like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the intended point of impact. Many contemporary rifle scopes and optics have around eleven parts which are located inside and externally on the optic. These scope parts include the rifle scope’s body, lenses, adjustment turrets, focus rings, and other parts. Learn about the eleven parts of optics.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane an optic has establishes where the reticle or crosshair is located in regard to the scopes magnification. It simply suggests the reticle is located behind or ahead of the magnifying lens of the optic. Picking out the most ideal style of rifle optic is based on what variety of hunting or shooting you plan on undertaking.
Info About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This triggers the reticle to increase in size based upon the amount of magnification being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the exact same tick at one hundred yards by using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are very little
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” ratios for their long guns
- Shooters who do not mind the reticle is bigger and takes up more visual sight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) include 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 reticle measurement.
- Far away styles of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots happen within much shorter proximities and ranges
- Shooters who want a clearer optic picture with less area taken up by the larger size FFP reticle
Zoom for Rifle Glass
The amount of scope magnification you require is based on the style of shooting you desire to do. Almost every style of rifle optic offers some degree of zoom. The quantity of magnification a scope supplies is identified by the diameter, density, and curvatures of the lens glass inside of the rifle optic. The magnifying level of the scope is the “power” of the scope. This indicates what the shooter is checking out through the scope is amplified times the power factor of what can normally be seen by human eyes.
Single Power Lens Rifle Optics
A single power rifle scope will have 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 change given that it is a fixed power scope.
Variable Power Lens Optic Info
Variable power rifle scopes can be adjusted between magnification power levels. These types of scopes will note the zoom level in a format such as 2-10×32. These numbers indicate the zoom of the scope could be changed between 2x and 10x power. This additionally includes the powers in-between 2 and 10. The power manipulation is achieved utilizing the power ring component of the scope near the back of the scope by the eye bell piece.
Power and Range
Here are some suggested scope powers and the distances where they could be effectively used. Always remember that higher magnification scopes will not be as efficient as lower powered optics due to the fact that too much magnification can be a detractor. The same concept goes for extended ranges where the shooter needs to have enough power to see where to best aim the rifle.
Rifle Glass Lens Coating
All contemporary rifle optic lenses are layered. There are various types and qualities of finishes. When considering high end rifle optical units, Lens finishing can be a significant element of defining the capability of the rifle. The glass lenses are among the most essential pieces of the scope since they are what your eye looks through while sighting a rifle in on the point of impact. The finishing on the lenses safeguards the lens surface and even assists with anti glare capabilities from refracted sunrays and color discernibility.
About Lens Coatings – HD Versus ED
Some scope producers likewise use “HD” or high-definition lens coverings which use different methods, polarizations, chemicals, and elements to draw out separate colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Rifle Glass Lens Single Coating Versus Multi-Coating
Various optic lenses can also have different coatings applied to them. All lenses generally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
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 lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope developer and just how much you spent on it. Both the make and cost are indicators of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Hydrophobic Lens Covering
Water on an optic’s lens does not help with preserving a clear sight picture through an optic whatsoever. Many top of the line or high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior of the Steiner scope lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Alternatives for Installing Rifle Glass on Long Guns
Mounting solutions for scopes are available in a few options. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically can be found in quick release versions which use toss levers which enable rifle operators to rapidly mount and remove the glass.
Hex Key Rifle Scope Rings
Standard, clamp-on style mounting optic rings use hex head screws to position to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two detached rings to support the optic, and are normally made from 7075 T6 billet aluminum or similar materials which are developed for far away accuracy shooting. This type of scope mount is exceptional for rifle systems which require a durable, rock solid mount which will not move no matter how much the scope is moved about or abuse the rifle takes. These are the style of mounts you really want to have for a faithful scope setup on a far away hunting or sniper competition long gun that will seldom need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the mount’s screws to stop the hex screws from backing out after they are mounted securely in position. An example of these rings are the 30mm type made by the Vortex Optics company. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle. Several scopes can also be switched out if they all use a similar style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining accuracy. These kinds of mounts are useful and convenient for shooting platforms which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are utilized between a number of rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It usually costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can mess up a day of shooting and your pricey optic by bringing about fogging and developing residue inside of the scope tube. A lot of scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
What to Know About Scope Tube Gas Purging
Another element of avoiding the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less affected by temperature shifts and pressure distinctions from the external environment which could potentially enable 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 look for.
