What You Need to Know About Glass
Rifle scopes allow you to specifically aim a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnification by utilizing a series of lenses inside the scope. The scope’s positioning can be adjusted to account for many environmental aspects like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will land based upon the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle optics have around eleven parts which are found internally and on the exterior of the optic. These optic pieces include the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other elements. Learn about the eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the best type of rifle glass depends on what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who recognize their aim point “hold over” and also “lead” correlations for their firearm
- Shooters who do not mind the reticle is bigger and requires more visual sight room than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots happen within much shorter spaces and ranges
- Shooters who like a clearer optic sight picture with less room used up by the bigger FFP reticle
About Rifle Optic Magnification
The level of scope zoom you need is based on the sort of shooting you intend to do. Practically every style of rifle scope offers some degree of magnification. The volume of zoom a scope gives is established by the size, density, and curvatures of the lenses inside of the rifle optic. The magnification of the scope is the “power” of the glass. This indicates what the shooter is looking at through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Single Power Lens Rifle Scope Facts
A single power rifle scope will have a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not fluctuate since it is fixed.
Adjustable Power Lens Optics
Variable power rifle scopes can be changed between magnification power levels. It will list the magnification amount in a configuration such as 2-10×32. These numbers indicate the magnification of the scope can be adjusted between 2x and 10x power. This always includes the powers in-between 2 and 10. The power adjustment is accomplished by applying the power ring component of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range of Rifle Optics
Here are some suggested scope power settings and the distances where they may be efficiently used. Highly magnified glass will not be as efficient as lower magnification level scopes since too much zoom can be a negative aspect depending on your shooting distance. The same idea applies to extended ranges where the shooter needs to have adequate power to see precisely where to properly aim the rifle at the target.
Rifle Scope Lens Covering
All top teir rifle glass lenses are layered. Lens covering is a vital element of a rifle when thinking about high end rifle optics and scope systems.
HD Versus ED Rifle Optic Lens Coatings
Some scope brands likewise use “HD” or high-definition lens finishes which use various procedures, components, chemicals, and polarizations to draw out separate colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Different optic lenses can likewise have different coatings used to them. All lenses normally have at least some type of treatment or finishing used to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope company and the amount you paid for it. Both are indicators of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are covered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of products used in developing the rifle scope.
About 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 hydrophobic or hydrophilic covering.
Scope Mounting Options
Mounting approaches for scopes can be found in a few options. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also generally can be found in quick release variations which use manual levers which enable rifle operators to quickly install and dismount the scopes.
Hex Key Rifle Optic Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long range accuracy shooting. This type of scope mount is excellent for rifles which require a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Scope Rings
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, multiple scopes can also be swapped on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping precision. These kinds of mounts come in practical for rifles which are transported a lot, to take off the optic from the rifle for protection, or for scopes which are chosen for use in between multiple rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It normally costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle optic can destroy a day of shooting and your costly optic by triggering fogging and developing residue inside of the scope tube. A lot of scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Scope Tubes
Another component of preventing the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the optic is less influenced by temp shifts and pressure differences from the outdoor environment which might possibly permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
