About Glass
Rifle scopes enable you to specifically align a rifle at various targets by aligning your eye with the target at range. They do this through magnification using a set of lenses inside the scope. The scope’s positioning can be adapted for the consideration of separate natural considerations like wind and elevation increases 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 seeing via the optic as you line up the scope’s crosshair or reticle with the target. A lot of modern-day rifle scopes and optics have about eleven parts which are found inside and externally on the scope. These parts include the rifle scope’s body, lenses, adjustment dials, focus rings, and other parts. Learn about the eleven parts of scopes.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the best type of rifle glass is based around what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based on the extent of magnification being used. The result is that the reticle measurements are the same at the enhanced range as they are at the non amplified distance. For instance, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are minimal
- Experienced shooters who understand their target “hold over” and “lead” equations for their rifles
- Shooters who don’t mind the reticle is enlarged and requires more visual sight space than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) come with the reticle behind the magnification 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.
- Far away forms of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots occur within much shorter spaces and ranges
- Shooters who choose a clearer optic picture with less room used up by the bigger FFP reticle
Zoom for Optics
The quantity of scope magnification you need on your scope depends on the style of shooting you want to do. Practically every kind of rifle glass provides some degree of zoom. The quantity of zoom a scope offers is established 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 suggests what the shooter is aiming at through the scope is magnified times the power factor of what can usually be seen by human eyes.
About Fixed Single Power Lens Rifle Scopes
A single power rifle scope and optic comes with a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not adjust since it is a fixed power scope.
Info About Variable Power Lens Scopes
Variable power rifle scopes can be changed between magnification increments. It will list the magnification degree in a configuration such as 2-10×32. These numbers imply the magnification of the scope could be adjusted between 2x and 10x power. This always includes the powers in-between 2 and 10. The power adaptation is accomplished using the power ring component of the scope near the rear of the scope by the eye bell piece.
Rifle Optic Power and Range Correlation
Here are some recommended scope power levels and the ranges where they may be successfully used. Bear in mind that higher magnification glass will not be as efficient as lower magnification level scopes due to the fact that increased magnification can be a detractor. The same idea goes for longer ranges where the shooter needs to have enough power to see exactly where to properly aim the rifle.
Lens Coating for Rifle Glass
All contemporary rifle optic and scope lenses are covered in special coatings. There are various types and qualities of lens finishings. Lens covering is an important element of a rifle’s setup when looking at high-end rifle optics and targeting equipment. The glass lenses are among the most vital pieces of the scope given that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses offers protection to the lens surface area and also assists with anti glare capabilities from excess sunrays and color visibility.
HD Versus ED Lenses
Some scope producers also use “HD” or high-definition lens coverings which use different techniques, polarizations, aspects, and chemicals to draw out different colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Coating Versus Multi-Coating
Various optic lenses can also have different finishings applied to them. All lenses usually have at least some type of treatment or covering used to them before being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope producers likewise make it a point to specify if their optic lenses are layered or “multi” coated. This means the lens has numerous treatments applied to them. If a lens receives numerous treatments, it can indicate that a producer is taking numerous actions to combat different environmental factors like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This additionally does not always imply the multi-coated lens is better than a single covered lens. Being “better” depends on the maker’s lens treatment techniques and the quality of products used in creating the rifle scope.
Anti-water Rifle Optic Lens Finishing
Water on a lens does not help with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end scope companies will coat their lenses with a hydrophobic or hydrophilic finish.
Options for Installing Rifle Scopes on Long Guns
Installing options for scopes can be found in a couple of options. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also typically come in quick release variations which use throw levers which enable rifle shooters to quickly install and remove the glass.
Hex Key Glass Rings
Normal, 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 distance precision shooting. This type of scope install is wonderful for rifles which require a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle. If they all use a comparable design mount, multiple scopes can often be switched on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining accuracy. These types of mounts are useful and practical for shooting platforms which are shipped a lot, to take off the scope from the rifle for protection, or for optics which are used between several rifles. An example of this mount style is the 30mm mount from Vortex Optics. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle scope can destroy a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. A lot of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Info Around Rifle Optic Tube Gas Purging
Another element of preventing the buildup of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the optic is less affected by temp shifts and pressure distinctions from the outside environment which could potentially permit water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
