Glass Facts
Rifle scopes permit you to exactly aim a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through magnifying the target by making use of a set of lenses inside the scope. The scope’s positioning can be adapted to account for numerous ecological elements like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based on the sight picture you are seeing with the optic as you align the scope’s crosshair or reticle with the target. Most modern-day rifle scopes have around 11 parts which are found internally and externally on the scope body. These scope parts consist of the rifle scope’s body, lenses, elevation dials or turrets, focus rings, and other parts. See all eleven parts of a rifle scope.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has identifies where the reticle or crosshair lies in relation to the optic’s magnification. It simply means the reticle is situated behind or in front of the magnification lens of the optic. Considering the most reliable style of rifle scope is based on what variety of shooting or hunting you intend on doing.
About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This triggers the reticle to increase in size based on the amount of zoom being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the identical tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who understand their target “hold over” and “lead” ratios for their weapon
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight room than a SFP reticle
Second Focal Plane Scope Info
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away styles of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots take place within much shorter ranges and proximities
- Shooters who want a clearer optic picture with less room taken up by the larger sized FFP reticle
Zoom for Scopes
The measure of scope magnification you need on your optic depends upon the form of shooting you want to do. Practically every kind of rifle scope delivers some degree of magnification. The level of magnification a scope gives is identified by the diameter, density, and curves of the lens glass within the rifle optic. The magnification of the scope is the “power” of the glass. This signifies what the shooter is looking at through the scope is amplified times the power aspect of what can generally be seen by human eyes.
Fixed Single Power Lens Rifle Scopes
A single power rifle optic and scope will have a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not adjust considering that it is a fixed power optic.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. It will note the zoom degree in a configuration like 2-10×32. These numbers indicate the magnification of the scope can be set in between 2x and 10x power. This additionally includes the powers in-between 2 and 10. The power adaptation is achieved utilizing the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Glass Power Level and Ranges
Here are some advised scope power settings and the distances where they may be effectively used. High power rifle scope glass will not be as beneficial as lower magnification optics considering too much magnification can be a bad thing. The same concept goes for longer ranges where the shooter needs sufficient power to see where to properly aim the rifle.
Rifle Scope Lens Finish
All modern rifle scope lenses are layered. There are various types and qualities of glass finishings. Lens finishing can be a crucial element of a rifle’s setup when thinking of high end rifle optics and targeting systems. The glass lenses are one of the most key components of the scope due to the fact that they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses safeguards the lens surface as well as helps with anti glare from refracted natural light and color perception.
Info on Rifle Optic Lens Coatings – HD Versus ED
Some optic manufacturers also use “HD” or high-definition glass coatings which use various procedures, rare earth compounds, polarizations, and elements to draw out separate colors and viewable target visibility through the lens. This high-def coating is commonly used with more costly, high density lens glass which decreases light’s capability to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” signifying extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around items with well defined shapes as light hits the object from specific angles.
Optic Lens Single Finish Versus Multi-Coating
Different optic lenses can even have various coatings applied to them. All lenses typically have at least some kind of treatment or coating applied to them before being used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It needs to have a coating applied to it so that the lens will be efficiently functional in lots of types of environments, degrees of sunshine (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 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 coated lens depends upon the scope developer and the amount you spent on it. The scope’s maker and cost are indicators of the lens quality.
Some scope manufacturers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Anti-water Finish for Rifle Glass
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finishing which is water repellent.
Alternatives for Installing Rifle Optics on Firearms
Mounting options for scopes can be found in a couple of choices. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually come in quick release versions which use toss levers which permit rifle operators to rapidly mount and remove the scopes.
Hex Key Rifle Scope Ring Mounting Solutions
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This type of scope mount is wonderful for rifles which need a resilient, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. Several scopes can also be switched 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 solidly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping the original sighting settings. These types of mounts come in convenient for rifles which are moved around a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are chosen for use between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your pricey optic by bringing about fogging and creating residue inside of the scope tube. Many scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are waterproof.
Info on Optic Tube Gas Purging
Another component of avoiding the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the glass is less altered by climate shifts and pressure distinctions from the outside environment which may possibly enable 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.
