Information Rifle Glass
Rifle scopes allow you to precisely aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification by employing a set of lenses within the scope. The scope’s alignment can be adapted for consideration of numerous natural considerations like wind and elevation increases to account for bullet drop.
The scope’s function is to 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 intended point of impact. The majority of modern rifle scopes have around eleven parts which are arranged within and outside of the optic. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials or turrets, focus rings, and other elements. See all eleven parts of a rifle scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the optimal type of rifle scope is based around what type of shooting you plan on doing.
First Focal Plane Optic Details
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who understand their target “hold over” and “lead” relationships for their weapon
- Shooters who don’t mind the reticle is bigger and requires more visual sight space than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane optics (SFP) come with 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 forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots occur within much shorter ranges and distances
- Shooters who desire a clearer optic sight picture with less area taken up by the larger sized FFP reticle
Magnification for Rifle Optics
The amount of magnification a scope provides is figured out by the diameter, thickness, 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 Glass Details
A single power rifle optic or scope will have a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not adjust because it is a fixed power scope.
About Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will list the magnification level in a configuration like 2-10×32. These numbers suggest the zoom of the scope could be set between 2x and 10x power. This also 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.
Rifle Optic Power and Range Correlation
Here are some recommended scope powers and the distances where they can be effectively used. Consider that higher power optics will not be as practical as lower powered scopes because too much magnification can be a bad thing. The exact same idea applies to extended distances where the shooter needs adequate power to see exactly where to best aim the rifle.
Scope Lens Finishing
All present day rifle scope lenses are covered. Lens covering is an important aspect of a rifle’s setup when considering high end rifle optics and scope setups.
About Rifle Optic Lens Coatings – HD Versus ED
Some scope brands likewise use “HD” or high-definition lens coverings which use different methods, chemicals, polarizations, and elements to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Covering Versus Multi-Coating
Different optic lenses can also have various finishes applied to them. All lenses generally have at least some type of treatment or covering applied to them before being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope makers likewise make it a point to specify if their optic lenses are coated or “multi” coated. This indicates the lens has several treatments applied to the surfaces. If a lens receives numerous treatments, it can show that a manufacturer is taking multiple steps to combat different natural elements like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This additionally does not necessarily imply the multi-coated lens is better than a single coated lens. Being “better” depends upon the maker’s lens treatment techniques and the quality of components used in developing the rifle scope.
Hydrophobic Lens Finish
Water on a lens does not help with maintaining a clear sight picture through a scope whatsoever. Many top of the line and premium optic producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with 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 slide off of the scope to preserve a clear, water free sight picture.
Rifle Glass Installing Options
Installing solutions for scopes come in a few 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 kinds of mounts also usually can be found in quick release variations which use throw levers which allow rifle operators to rapidly install and dismount the optics.
Rifle Optic Mounting Solutions with Hex Key Rings
Basic, clamp type mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mount rails on rifles. These varieties of scope mounts use a pair of independent rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are developed for long distance precision shooting. This kind of scope mount is ideal for rifle systems which need to have a resilient, rock solid mount which will not move despite how much the scope is moved or jarring the rifle takes. These are the design of mounts you really want to have for a specialized optics setup on a long distance hunting or interdiction rifle that will almost never need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount screws to protect against the hex screw threads from wiggling out after they are mounted securely 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 Rifle Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and connect it to a different rifle. Multiple scopes can even be swapped out if they all use a similar style mount. These types of mounts are convenient for rifles which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles.
Info on Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day on the range and your pricey optic by causing fogging and producing residue inside of the scope tube. A lot of optics prevent humidity from entering the scope tube with a system of sealing O-rings which are water resistant. Generally, these water resistant scopes can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of wetness avoidance for conventional use rifles, unless you intend on taking your rifle on your motorboat and are worried about the optic still working if it is submerged in water and you can still retrieve the firearm.
Rifle Glass Gas Purging
Another component of avoiding the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the scope is less impacted by condition shifts and pressure distinctions from the outdoor environment which might potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
