Scope Information
Rifle scopes enable you to exactly align a rifle at different targets by aligning your eye with the target over a range. They do this through magnification by employing a set of lenses within the scope. The scope’s alignment can be dialed in for consideration of varied environmental factors like wind and elevation to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based on the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle scopes have about 11 parts which are found inside and externally on the scope body. These parts include the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other components. Learn about the eleven parts of rifle scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The type of focal plane a scope has establishes where the reticle or crosshair is located relative to the scopes zoom. It literally suggests the reticle is behind or ahead of the magnifying lens of the optic. Looking for the most ideal type of rifle optic depends upon what kind of hunting or shooting you anticipate doing.
Info on First Focal Plane Glass
First focal plane scopes (FFP) include the reticle in front of the zoom lens. This causes the reticle to increase in size based on the level of zoom being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non amplified distance. As an example, one tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are marginal
- Experienced shooters who recognize their aim point “hold over” and “lead” equations for their weapon
- Shooters who do not mind the reticle is enlarged and occupies more visual sight space than a SFP reticle
Second Focal Plane Glass Info
Second focal plane scopes (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick.
- Far away styles of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots occur within shorter ranges and spaces
- Shooters who desire a clearer optic picture without area used up by the larger sized FFP reticle
Ins and Outs of Rifle Glass Magnification
The quantity of zoom a scope supplies is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Glass
A single power rifle scope and optic comes with a zoom number designator like 4×32. This indicates the magnification 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 scope.
Info on Variable Power Lens Rifle Optics
Variable power rifle scopes use variable power levels. The power change is achieved using the power ring part of the scope near the back of the scope by the eye bell.
Scope Power Level and Ranges
Here are some suggested scope power settings and the distances where they can be efficiently used. Highly magnified optics will not be as beneficial as lower powered rifle scope glass considering that too much zoom can be a bad thing. The exact same concept applies to longer distances where the shooter needs sufficient power to see exactly where to best aim the rifle.
Lens Finish for Rifle Optics
All state-of-the-art rifle scope lenses are covered. Lens coating is a crucial aspect of a shooting system when thinking about high end rifle optics and scope setups.
HD Versus ED Rifle Glass Lens Coatings
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use different procedures, elements, polarizations, and chemicals to draw out various colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Rifle Glass Lens Single Covering Versus Multi-Coating
Different optic lenses can also have different coverings applied to them. All lenses usually have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a finish put on it so that it will be efficiently functional in lots of kinds of environments, degrees of light (full light VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while lowering glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” coated. This indicates the lens has multiple treatments applied to them. If a lens receives several treatments, it can establish that a company is taking several actions to fight various environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This additionally doesn’t always indicate the multi-coated lens is better than a single covered lens. Being “much better” hinges on the manufacturer’s lens treatment solutions and the quality of products used in building the rifle optic.
Hydrophobic Optic Lens Covering
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic finishing.
Alternatives for Mounting Rifle Scopes on Firearms
Installing options for scopes are available in a few choices. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also normally are made in quick release variations which use manual levers which permit rifle shooters to quickly mount and dismount the optics.
Hex Key Glass Ring Mounting Solutions
Basic, clamp-on style mounting optic rings use hex head screws to position to the flattop style Picatinny scope mounting rails on rifles. These forms of scope mounts use a pair of separate rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are made for far away precision shooting. This kind of scope mount is ideal for rifle systems which need to have a long lasting, hard use mount which will not move despite how much the scope is moved or jarring the rifle takes. These are the design of mounts you should have for a dedicated scope system on a far away hunting or competitors firearm which will rarely 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 backing out after they are installed firmly in position. An example of these rings are the 30mm type from the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and attach it to a different rifle. Multiple scopes can even be swapped out if they all use a compatible design mount. These types of mounts are handy for rifles which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between multiple rifles or are situationally focused.
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. Most scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Rifle Scope Gas Purging
Another element of preventing the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the scope is less influenced by temperature shifts and pressure distinctions from the outdoor environment which may potentially enable water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
