All About Glass
Rifle scopes enable you to specifically align a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification by making use of a series of lenses inside the scope. The scope’s positioning can be adapted to account for many environmental considerations like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based upon the sight picture you are seeing with the optic as you line up the scope’s crosshair or reticle with the target. Most modern-day rifle scopes and optics have around 11 parts which are found inside and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other components. See all eleven parts of optics.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has decides where the reticle or crosshair lies in connection with the scopes magnifying adjustments. It actually means the reticle is behind or before the magnifying lens of the scope. Considering the most suitable sort of rifle scope depends on what sort of hunting or shooting you intend on undertaking.
First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are minimal
- Experienced shooters who know their aim point “hold over” plus “lead” equations for their weapon
- Shooters who don’t mind the reticle is bigger and takes up more visual sight room than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane glass (SFP) include the reticle to the rear of the magnifying lens. This triggers the reticle to remain at the same overall size relative to the amount of magnification being used. The end result is that the reticle dimensions adapt based upon the magnification chosen to shoot over longer ranges given that the markings represent various increments which fluctuate with the magnification. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular varieties of glass work for:
- Far away types of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots take place within much shorter ranges and proximities
- Shooters who select a clearer optic picture with less area taken up by the larger sized FFP reticle
Magnification for Rifle Scopes
The amount of scope zoom you need depends on the kind of shooting you choose to do. Practically every kind of rifle scope supplies some degree of magnification. The amount of zoom a scope gives is identified by the size, density, and curvatures of the lens glass within the rifle scope. The magnification of the scope is the “power” of the scope. This means what the shooter is checking out through the scope is amplified times the power aspect of what can generally be seen by human eyes.
Info on Single Power Lens Optics
A single power rifle scope comes with a zoom 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 scope can not adjust since it is a fixed power optic.
Variable Power Lens Rifle Optic Facts
Variable power rifle scopes use enhanced power. The power change is performed by making use of the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some suggested scope powers and the distances where they could be effectively used. Keep in mind that higher magnification optics and scopes will not be as effective as lower magnification level scope and optics because too much zoom can be a bad thing. The exact same idea applies to extended distances where the shooter needs enough power to see where to properly aim the rifle.
Rifle Glass Lens Coating
All modern rifle scope and optic lenses are covered. Lens covering can be a vital element of a shooting platform when considering high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope manufacturers also use “HD” or high-definition lens coatings which use various processes, chemicals, polarizations, and aspects to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Coating Versus Multi-Coating for Scopes
Various optic lenses can even have various coatings applied to them. All lenses generally have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic assembly. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally usable in lots of types of environments, degrees of sunlight (full VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing 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 upon the scope developer and the amount you spent paying for it. Both the manufacturer and amount are indications of the lens quality.
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 maker’s lens treatment technology and the quality of materials used in building the rifle scope.
Rifle Optic Lens Hydrophobic Coating
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Many top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic coating.
Options for Mounting Optics on Firearms
Mounting solutions for scopes can be found in a couple of choices. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release versions which use throw levers which enable rifle shooters to rapidly install and dismount the glass.
Hex Key Rifle Glass Ring Mounts
Standard, clamp-on type mounting scope rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on rifles. These styles of scope mounts use two detached rings to support the scope, and are made from 7075 T6 billet aluminum which are made for long distance precision shooting. This type of scope mount is very good for rifles which need a durable, unfailing mount which will not move regardless of just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should have for a specialized optics system on a far away hunting or tournament firearm that will almost never need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to keep the hex screw threads from backing out after they are installed tightly in place. An example of these rings are the 30mm style made by the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a compatible design mount. These types of mounts come in handy for long guns which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are used between numerous rifles or are situationally focused.
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can wreck a day of shooting and your highly-priced optic by resulting in fogging and generating residue within the scope’s tube. The majority of optics protect against moisture from getting in the optical tube with a series of sealing O-rings which are waterproof. Generally, these water resistant optics can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient moisture content prevention for conventional use rifles for hunting and sporting purposes, unless you anticipate taking your rifle sailing and are worried about the optic still working if it is submerged in water and you can still rescue the firearm.
Rifle Scope Gas Purging
Another component of avoiding the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the optic is less altered by climate alterations and pressure distinctions from the outdoor environment which could potentially permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
