What You Need to Know About Rifle Glass
Rifle scopes allow you to specifically aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by utilizing a set of lenses within the scope. The scope’s alignment can be dialed in to take into account numerous ecological things like wind speed and elevation decreases 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 viewing with the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle scopes and optics have about eleven parts which are arranged within and outside of the scope. These optic pieces include the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other parts. Learn about the eleven parts of scopes.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Finding the best type of rifle scope depends on what type of shooting you plan on doing.
Info on First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who recognize their aim point “hold over” and also “lead” correlations for their firearm
- Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight space than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Far away forms of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots occur within much shorter ranges and proximities
- Shooters who prefer a clearer optic picture without room taken up by the bigger FFP reticle
Magnification for Rifle Glass
The amount of scope zoom you need on your scope depends on the kind of shooting you would like to do. Practically every style of rifle scope provides some level of magnification. The quantity of magnification a scope gives is identified by the dimension, density, and curvatures of the lenses inside of the rifle optic. The magnification level of the optic is the “power” of the glass. This implies what the shooter is aiming at through the scope is amplified times the power factor of what can typically be seen by human eyes.
Fixed Power Lens Rifle Scopes
A single power rifle optic and scope uses 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 zoom of this kind of scope can not fluctuate considering that it is a fixed power scope.
About Adjustable Power Lens Scopes
Variable power rifle scopes have adjustable power. It will note the magnification amount in a format like 2-10×32. These numbers mean the magnification of the scope can be adjusted between 2x and 10x power. This always involves the power levels in-between 2 and 10. The power adaptation is achieved by employing the power ring part of the scope near the back of the scope by the eye bell.
Rifle Optic Power and Range Correlation
Here are some suggested scope powers and the distances where they could be effectively used. High power rifle scope glass will not be as effective as lower powered optics considering too much zoom can be a negative aspect depending on your shooting distance. The same relates to extended distances where the shooter needs adequate power to see exactly where to properly aim the rifle.
Info on Lens Finishes
All modern rifle glass lenses are coated. Lens finishing is a vital aspect of a rifle system when looking into high end rifle optics and scope systems.
Details on Lens Coatings – HD Versus ED
Some scope companies will also use “HD” or high-definition lens coatings that use various procedures, elements, chemical substances, and polarizations to extract separate color ranges and viewable definition through the lens. This high-definition covering is commonly used with increased density lens glass which lowers light’s potential to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration is often noticeable over items with hard edges and outlines as light hits the item from specific angles.
Rifle Glass Lens Single Finish Versus Multi-Coating
Various optic lenses can also have various finishes used to them. All lenses generally have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while lowering glare and other less beneficial 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 producers similarly make it a point to specify if their optic lenses are layered or “multi” coated. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in building the rifle scope.
Details on Hydrophobic Finish
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Many top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic covering which is water repellent.
Rifle Optic Mounting Options
Mounting options for scopes can be found in a few options. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also usually can be found in quick release variations which use toss levers which permit rifle shooters to quickly install and remove the optics.
Hex Key Scope Rings
Standard, clamp-on design mounting scope rings use hex head screws to position to the flattop design Picatinny scope mount rails on rifles. These kinds of scope mounts use a pair of individual rings to support the scope, and are normally made from 7075 T6 billet aluminum which are made for long distance accuracy shooting. This kind of scope mount is exceptional for rifles which need to have a resilient, rock solid mount which will not shift regardless of how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should have for a devoted optics system on a far away hunting or sniper competition firearm which will hardly ever need to be altered 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 from the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be swapped out if they all use a similar design mount. These types of mounts are convenient for long guns which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between numerous rifles or are situationally focused.
Sealing and Gas Purging for Scope Tubes
Moisture inside your rifle scope can ruin a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. Many scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Info Around Rifle Scope Tube Gas Purging
Another part of avoiding the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the scope is less impacted by temperature level alterations and pressure differences from the outdoor environment which could possibly allow water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
