Rifle Scope Information
Rifle scopes allow you to exactly align a rifle at various targets by aligning your eye with the target at range. They do this through zoom by using a series of lenses inside the scope. The scope’s alignment can be dialed in for the consideration of various natural things like wind speed 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 upon the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the intended target. Most modern-day rifle scopes and optics have about 11 parts which are found within and outside of the optic. These optic pieces consist of the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other elements. See all eleven parts of a scope.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane a scope has identifies where the reticle or crosshair lies in relation to the optic’s magnifying adjustments. It actually implies the reticle is behind or ahead of the magnification lens of the scope. Considering the most beneficial style of rifle scope depends upon what style of hunting or shooting you intend on undertaking.
First Focal Plane Optics
First focal plane glass (FFP) feature the reticle before the magnification lens. This causes the reticle to increase in size based on the level of magnification being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the identical tick at one hundred yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are minor
- Experienced shooters who understand their aim point “hold over” and “lead” correlations for their long guns
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) feature the reticle to the rear of the magnification lens. This causes the reticle to remain at the same scale in relation to the amount of magnification being used. The outcome is that the reticle measurements change based on the magnification used to shoot over longer ranges given that the reticle markings present distinct increments which vary with the zoom. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular sorts of scopes work for:
- Long distance types of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots take place within shorter spaces and ranges
- Shooters who like a clearer optic sight picture with less room taken up by the larger size FFP reticle
Optic Zoom
The level of scope zoom you need on your glass depends upon the type of shooting you would like to do. Just about every type of rifle glass offers some degree of zoom. The volume of magnification a scope offers is established by the size, thickness, and curves of the lenses inside of the rifle scope. The zoom of the optic is the “power” of the scope. This indicates what the shooter is observing through the scope is magnified times the power factor of what can usually be seen by human eyes.
Fixed Power Lens Glass
A single power rifle scope or optic uses 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 fluctuate since it is a set power scope.
Adjustable Power Lens Optics
Variable power rifle scopes can be changed between magnification increments. These types of scopes will note the magnification degree in a configuration like 2-10×32. These numbers suggest the magnification of the scope could be set in between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power shift is achieved using the power ring part of the scope near the back of the scope by the eye bell piece.
Optic Power Level and Range Correlation
Here are some suggested scope power levels and the ranges where they can be successfully used. Highly magnified rifle scope glass will not be as effective as lower magnification scopes due to the fact that too much magnification can be a bad thing. The same applies to extended distances where the shooter needs to have increased power to see exactly where to properly aim the rifle.
Rifle Optic Lens Finishing
All contemporary rifle optic lenses are covered in special coatings. There are various types and qualities of finishings. When considering high end rifle scope devices, Lens covering can be an essential element of a rifle. The glass lenses are one of the most crucial parts of the optic since they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses offers protection to the lens surface as well as assists with anti glare capabilities from refracted sunrays and color presence.
HD Versus ED Scope Lens Coatings
Some scope manufacturers also use “HD” or high-definition lens coverings which use different methods, aspects, polarizations, and chemicals to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Glass
Various scope lenses can also have different coverings applied to them. All lenses normally have at least some type of treatment or coating applied to them before being used in a rifle scope or optic. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently functional in numerous types of environments, degrees of light (full VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope makers similarly make it a point to specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the maker’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Hydrophobic Coating for Scopes
Water on a lens does not help with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic finishing.
Choices for Installing Glass on Long Guns
Installing approaches for scopes come in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally are made in quick release variations which use throw levers which allow rifle shooters to rapidly mount and dismount the glass.
Hex Key Rifle Optic Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design 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 developed for long distance precision shooting. This type of scope install is wonderful for rifles which require a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Ring Mounts
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. Multiple scopes can also be swapped out if they all use a complementary designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping accuracy. These kinds of mounts are useful and beneficial for shooting platforms which are moved around a lot, to remove the glass from the rifle for protection, or for aiming systems which are used in between a number of rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It usually costs around $250 USD
Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your pricey optic by bringing about fogging and developing residue inside of the scope tube. A lot of scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another element of preventing the accumulation of wetness within 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 scope is less altered by climate alterations and pressure variations from the outdoor environment which may possibly enable water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
