Glass Information

Rifle scopes enable you to specifically align 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 inside the scope. The scope’s alignment can be dialed in for consideration of separate natural things like wind speed and elevation decreases to make up for bullet drop.

The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the target. The majority of modern-day rifle scopes and optics have around eleven parts which are arranged within and on the exterior of the scope. These parts include the rifle scope’s body, lenses, modification turrets, objective focus rings, and other elements. Learn about the eleven parts of optics.

Rifle Scope Varieties

Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has identifies where the reticle or crosshair lies in regard to the optic’s magnifying adjustments. It actually means the reticle is behind or before the magnifying lens of the optic. Selecting the most suitable form of rifle glass depends upon what sort of shooting you anticipate undertaking.

First Focal Plane Scopes

Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are helpful for:

  • Quick acquisition, far away kinds of shooting
  • Shooting situations where estimations are minor
  • Experienced shooters who know their aim point “hold over” as well as “lead” correlations for their weapon
  • Shooters who don’t mind the reticle is enlarged and requires more visual sight space than a SFP reticle

Second Focal Plane Scopes

Second focal plane optics (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.

  • Far away styles of shooting where shooters have additional time to make ballistic estimations
  • Shooting where most of the shots take place within much shorter ranges and distances
  • Shooters who select a clearer optic picture without room used up by the larger sized FFP reticle

Glass Zoom

The extent of scope magnification you need on your glass is based on the form of shooting you wish to do. Pretty much every kind of rifle optic offers some amount of magnification. The level of zoom a scope gives is determined by the diameter, thickness, and curves of the lenses within the rifle optic. The zoom of the scope is the “power” of the opic. This implies what the shooter is aiming at through the scope is amplified times the power element of what can generally be seen by human eyes.

Fixed Single Power Lens Rifle Glass Facts

A single power rifle scope and optic will have a magnification number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not change given that it is a fixed power optic.

Adjustable Power Lens Rifle Glass

Variable power rifle scopes use variable power levels. The power modification is performed by using the power ring part of the scope near the back of the scope by the eye bell.

Power Levels and Range Correlations

Here are some suggested scope power settings and the distances where they could be effectively used. Bear in mind that high magnification scopes and optics will not be as effective as lower powered optics since excessive zoom can be a bad thing. The same goes for longer distances where the shooter needs adequate power to see exactly where to properly aim the rifle at the target.

Details on Glass Lens Covering

All state-of-the-art rifle glass lenses are covered. Lens covering can be a vital aspect of a shooting system when considering high end rifle optics and scope setups.

HD Versus ED Lenses

Some scope makers also use “HD” or high-definition lens finishes which use different methods, chemicals, aspects, and polarizations to draw out different colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.

Single Coating Versus Multi-Coating

Different optic lenses can also have various coatings applied to them. All lenses generally have at least some type of treatment or coating used to them before they are used in a rifle scope or optic.

Single covered lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope maker and how much you spent paying for it. The scope’s maker and cost are indicators of the lens quality.

Some scope makers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “much better” depends on the maker’s lens treatment technology and the quality of products used in building the rifle scope.

Anti-water Rifle Glass Lens Finishing

Water on a lens does not help with maintaining a clear sight picture through an optic whatsoever. Lots of top of the line or high-end optic makers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the exterior surfaces of the Steiner glass lens so the water molecules can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.

Alternatives for Mounting Rifle Scopes on Firearms

Installing solutions for scopes can be found in a couple of options. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally can be found in quick release variations which use throw levers which allow rifle shooters to rapidly mount and remove the optics.

Hex Key Glass Rings

Standard, clamp design mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use two detached rings to support the optic, and are made from 7075 T6 billet aluminum which are made for far away precision shooting. This form of scope mount is good for rifles which are in need of a resilient, hard use mount which will not change regardless of how much the scope is moved or abuse the rifle takes. These are the type of mounts you should get for a devoted optics system on a reach out and touch someone scouting or hard target interdiction firearm that will pretty much never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to stop the hex screws from backing out after they are installed safely in place. An example of these mounting rings are the 30mm style made by the Vortex Optics brand. The set normally costs around $200 USD

Quick-Release Cantilever Scope Ring Mounting Solutions

These types of quick-release rifle scope mounts can be used to quickly take off a scope and connect it to a different rifle. Numerous scopes can even be swapped out if they all use a compatible design mount. These types of mounts are handy for rifles which are transported a lot, to remove the optic from the rifle for protection, or for scopes which are used in between numerous rifles.

Sealing and Gas Purging for Optic Tubes

Moisture inside your rifle optic can wreck a day on the range and your costly optic by causing fogging and creating residue inside of the scope’s tube. A lot of optics protect against moisture from going into the optical tube with a series 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 push moisture past the O-rings. This should be ample moisture content prevention for conventional use rifles, unless you plan on taking your rifle aboard a watercraft and are worried about the scope still performing if it goes over the side and you can still find the rifle.

Rifle Scope Gas Purging

Another part of preventing the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the scope is less altered by condition alterations and pressure variations from the outdoor environment which could possibly enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
