What You Need to Know About Rifle Glass

Rifle scopes enable you to specifically align a rifle at different targets by aligning your eye with the target over a distance. They do this through zoom using a set of lenses within the scope. The scope’s positioning can be dialed in to take into account various natural factors like wind speed and elevation increases or decreases to make up for bullet drop.

The scope’s purpose is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most modern rifle scopes and optics have about 11 parts which are arranged within and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other elements. See all eleven parts of scopes.

About Optic Types

Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the perfect type of rifle optic is based around what type of shooting you plan to do.

First Focal Plane Scope Facts

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

  • Quick acquisition, far away types of shooting
  • Shooting scenarios where computations are minimal
  • Experienced shooters who recognize their aim point “hold over” and “lead” correlations for their firearms
  • Shooters who do not mind the reticle is bigger and requires more visual eyesight space than a SFP reticle

About Second Focal Plane Optics

Second focal plane optics (SFP) come with the reticle behind 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.

  • Long distance forms of shooting where shooters have more time to make ballistic estimations
  • Shooting where most of the shots take place within much shorter ranges and proximities
  • Shooters who prefer a clearer optic picture with less area used up by the larger size FFP reticle

Magnification for Rifle Scopes

The extent of scope magnification you need on your glass depends upon the form of shooting you desire to do. Pretty much every kind of rifle scope offers some level of magnification. The amount of zoom a scope offers is determined by the dimension, density, and curves of the lenses within the rifle optic. The magnifying level of the scope is the “power” of the opic. This suggests what the shooter is looking at through the scope is amplified times the power aspect of what can usually be seen by human eyes.

Info About Single Power Lens Glass

A single power rifle scope or optic comes with a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change considering that it is a set power scope.

Variable Power Lens Scopes

Variable power rifle scopes use variable power levels. The power modification is handled by making use of the power ring part of the scope near the rear of the scope by the eye bell.

Rifle Optic Power and Ranges

Here are some advised scope powers and the distances where they may be successfully used. Always remember that high power optics and scopes will not be as practical as lower powered optics and scopes due to the fact that too much zoom can be a negative thing in certain situations. The exact same idea relates to longer ranges where the shooter needs to have sufficient power to see precisely where to best aim the rifle at the target.

About Optic Lens Finish

All contemporary rifle scope lenses are covered in special coatings. There are different types and qualities of coverings. When researching luxury rifle optical systems, Lens finishing can be a critical aspect of defining the capability of the rifle. The glass lenses are one of the most vital pieces of the optic as they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses shields the lens surface and also assists with anti glare capabilities from refracted daylight and color presence.

Details on Lens Coatings – HD Versus ED

Some glass producers even use “HD” or high-definition glass coatings that employ various procedures, chemicals, polarizations, and elements to enhance various colors and viewable target definition through lenses. This high-def coating is often used with greater density lens glass which reduces light’s capability to refract through the lens glass. Some scope manufacturers use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable over things with hard edges and outlines as light hits the object from various angles.

Single Finish Versus Multi-Coating for Optics

Various optic lenses can also have various finishings applied to them. All lenses typically have at least some type of treatment or coating used to them before being used in a rifle scope or optic.

Single layered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope developer and just how much you paid for it. Both the make and cost are signs of the lens quality.

Some scope producers also make it a point to specify if their optic lenses are coated or “multi” coated. Being “much better” depends on the producer’s lens treatment technology and the quality of materials used in developing the rifle scope.

About Hydrophobic Finishing

Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Many top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic finish.

Optic Installation Alternatives

Installing options for scopes are available in a couple of choices. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also normally come in quick release versions which use manual levers which enable rifle operators to rapidly install and remove the scopes.

Hex Key Rifle Scope Ring Mounts

Standard, clamp style mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on rifles. These forms of scope mounts use a pair of individual rings to support the scope, and are made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This kind of scope mount is very good for rifle systems which require a durable, rock solid mount which will not change despite how much the scope is moved about or abuse the rifle takes. These are the style of mounts you should have for a dedicated scope system on a long distance scouting or competitors firearm that will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the mount’s screws to prevent the hex screws from wiggling out after they are installed firmly in position. An example of these rings are the 30mm style from the Vortex Optics brand. The set generally costs around $200 USD

Glass Mounts with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to rapidly 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 design mount. These types of mounts are handy for rifle platforms which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are used between multiple rifles or are situationally focused.

About Glass Tube Sealing and Gas Purging

Moisture inside your rifle optic can mess up a day on the range and your costly optic by causing fogging and making residue within the scope tube. A lot of optics protect against humidity from going into the scope tube with a series of sealing O-rings which are water resistant. Normally, these optics 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 prevention for basic use rifles, unless you intend on taking your rifle on your motorboat and are concerned about the optic still functioning if it goes over the side and you can still rescue the gun.

Glass Gas Purging

Another part of preventing the accumulation of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the scope is less affected by condition changes and pressure distinctions from the outdoor environment which could potentially allow 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 look for.
