What You Need to Know About Glass
Rifle scopes permit you to specifically aim a rifle at various targets by aligning your eye with the target at range. They do this through zoom by employing a series of lenses within the scope. The scope’s alignment can be dialed in for consideration of different environmental elements like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes and optics have around 11 parts which are arranged internally and on the exterior of the optic. These parts include the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other elements. See all eleven parts of an optic.
About Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the best type of rifle glass depends on what type of shooting you plan to do.
Info on First Focal Plane Scopes
First focal plane scopes (FFP) include the reticle in front of the magnification lens. This induces the reticle to increase in size based upon 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 magnified distance. As an example, one tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who have an idea for their target “hold over” plus “lead” ratios for their rifles
- Shooters who do not mind the reticle is enlarged and requires more visual sight room than a SFP reticle
Second Focal Plane Optic Details
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. This triggers the reticle to remain at the same scale relative to the level of zoom being used. The end result is that the reticle dimensions change based upon the magnification used to shoot over lengthier ranges due to the fact that the reticle measurements represent different increments which vary with the magnification. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick. These particular styles of optics work for:
- Long distance forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots happen within much shorter spaces and ranges
- Shooters who like a clearer optic sight picture without area used up by the enlarged FFP reticle
Details on Glass Zoom
The quantity of scope magnification you need on your glass depends on the sort of shooting you desire to do. Practically every kind of rifle optic offers some degree of zoom. The level of zoom a scope delivers is identified by the size, thickness, and curvatures of the lens glass within the rifle scope. The magnifying level of the optic is the “power” of the opic. This signifies what the shooter is observing through the scope is magnified times the power factor of what can normally be seen by human eyes.
About Single Power Lens Rifle Optics
A single power rifle scope or optic will have 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 magnification of this kind of optic can not change given that it is a fixed power optic.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes use enhanced power. The power adjustment is performed by the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some suggested scope powers and the ranges where they can be effectively used. Remember that high power scopes and optics will not be as practical as lower magnification level glass due to the fact that too much magnification can be a bad thing. The same idea goes for extended ranges where the shooter needs to have adequate power to see exactly where to best aim the rifle.
Details on Lens Coatings
All present day rifle scope and optic lenses are covered. Lens covering can be a vital aspect of a rifle system when considering high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope manufacturers likewise use “HD” or high-definition lens coatings which use different methods, aspects, chemicals, and polarizations to draw out separate colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Various optic lenses can also have various finishings applied to them. All lenses normally have at least some type of treatment or finish applied to them before being used in a rifle scope or optic assembly. This is since the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally usable in many types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing 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 upon the scope manufacturer and just how much you spent paying for it. Both are indicators of the lens quality.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” covered. This implies the lens has had multiple treatments applied to the surfaces of the glass. If a lens receives several treatments, it can show that a manufacturer is taking numerous actions to combat various environmental aspects like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This additionally does not always indicate the multi-coated lens will perform better than a single coated lens. Being “much better” depends on the manufacturer’s lens treatment techniques and the quality of materials used in developing the rifle scope.
About Anti-water Coating
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finish.
Alternatives for Mounting Rifle Scopes on Firearms
Mounting solutions for scopes are available in a few options. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various types of mounts also typically can be found in quick release variations which use throw levers which enable rifle shooters to quickly install and dismount the optics.
Hex Key Rifle Scope Ring Mounting Solutions
Standard, clamp-on type mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mount rails on the tops of rifles. These types of scope mounts use double separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are manufactured for long distance accuracy shooting. This kind of scope mount is good for rifles which need to have a long lasting, unfailing mount which will not shift despite just how much the scope is moved or jarring the rifle takes. These are the type of mounts you really want to have for a specialized scope setup on a far away hunting or competition rifle that will seldom need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount screws to stop the hex screw threads from wiggling out after they are mounted securely in position. An example of these rings are the 30mm style from the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly detach a scope and attach it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible design mount. These types of mounts are handy for rifle platforms which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used between multiple rifles.
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle optic can destroy a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. Many scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Glass Tubes
Another element of avoiding the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the glass is less affected by condition shifts and pressure variations from the outdoor environment which may possibly permit water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
