About Rifle Glass
Rifle scopes enable you to specifically align a rifle at different targets by lining up your eye with the target at range. They accomplish this through zoom by employing a set of lenses inside the scope. The scope’s positioning can be dialed in for consideration of numerous environmental aspects like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based on the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the target. Most contemporary rifle scopes have around eleven parts which are located within and externally on the optic. These scope parts consist of the rifle scope’s body, lenses, windage turrets, objective focus rings, and other components. Learn about the eleven parts of rifle glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the finest type of rifle glass is based on what type of shooting you plan to do.
First Focal Plane Glass
First focal plane glass (FFP) feature the reticle before the zoom lens. This induces the reticle to increase in size based on the amount of zoom being used. The result is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at one hundred yards by using 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who understand their target “hold over” as well as “lead” correlations for their firearms
- Shooters who don’t mind the reticle is bigger and takes up more visual sight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots take place within much shorter ranges and proximities
- Shooters who would like a clearer optic sight picture with less area taken up by the bigger FFP reticle
Magnification for Rifle Glass
The quantity of zoom a scope offers is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Rifle Glass
A single power rifle scope or optic will have a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not fluctuate because it is set from the factory.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be tweaked between magnified levels. The power change is achieved using the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope power settings and the ranges where they can be efficiently used. Consider that higher power glass will not be as efficient as lower magnification level optics due to the fact that too much zoom can be a detractor. The exact same idea relates to extended distances where the shooter needs adequate power to see where to best aim the rifle at the target.
Details on Scope Lens Coating
All modern rifle optic lenses are layered. There are different types and qualities of glass coatings. Lens coating can be an important element of a rifle when thinking of luxury rifle optics and targeting equipment. The glass lenses are among the most critical components of the glass since they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses protects the lens surface area as well as helps with anti glare capabilities from refracted daylight and color profiles.
HD Versus ED Lenses
Some optic manufacturers will also use “HD” or high-definition glass coatings that apply different procedures, components, polarizations, and chemicals to enhance different colors and viewable target visibility through the lens. This high-def finishing is normally used with greater density lens glass which reduces light’s potential to refract through the lens glass. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration can be obvious around items with hard shapes as light hits the item from particular angles.
Details on Single Coating Versus Multi-Coating
Different optic lenses can likewise have different coverings applied to them. All lenses generally have at least some type of treatment or finish used to them before they are used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in developing the rifle scope.
Anti-water Rifle Scope Lens Finish
Water on a scope’s lens doesn’t improve maintaining a clear sight picture through an optic whatsoever. Lots of top of the line or premium optic makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the exterior surfaces of the Steiner glass lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Choices for Installing Rifle Optics on Firearms
Installing options for scopes come in a couple of choices. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also usually come in quick release variations which use manual levers which permit rifle shooters to quickly mount and dismount the scope.
Rifle Glass Mounting Solutions with Hex Key Rings
Standard, clamp design 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 a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope install is fine for rifles which require a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Rifle Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be switched out if they all use a similar style mount. These types of mounts are convenient for rifle platforms which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between multiple rifles.
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle glass can mess up a day on the range and your highly-priced optic by triggering fogging and creating residue inside of the scope tube. A lot of scopes protect against moisture from getting in the optical tube with a system of sealing O-rings which are waterproof. Generally, these water-resistant scopes can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture avoidance for common use rifles, unless you plan on taking your rifle on boats and are concerned about the optic still performing if it falls overboard and you can still recover the gun.
Info on Scope Tube Gas Purging
Another part of avoiding the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the optic is less impacted by climate changes and pressure variations from the outdoor environment which may potentially enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
