Scope Information
Rifle scopes allow you to exactly align a rifle at various targets by lining up your eye with the target at range. They do this through magnifying the target by employing a series of lenses inside the scope. The scope’s positioning can be dialed in for the consideration of numerous ecological aspects like wind speed and elevation to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. Many modern rifle optics have around eleven parts which are arranged internally and on the exterior of the optic. These optic pieces consist of the rifle scope’s body, lenses, elevation dials, objective focus rings, and other parts. See all eleven parts of scopes.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane a scope has decides where the reticle or crosshair is located in regard to the scopes zoom. It simply implies the reticle is located behind or before the magnification lens of the optic. Picking the very best form of rifle scope is based upon what type of hunting or shooting you plan on undertaking.
Info About First Focal Plane Glass
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based on the amount of magnification being used. The outcome is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. For example, one tick on a mil-dot reticle at 100 yards without any “zoom” is still the very same tick at one hundred yards using 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are minor
- Experienced shooters who recognize their aim point “hold over” and also “lead” relationships for their weapon
- Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane glass (SFP) include the reticle behind the magnifying lens. This causes the reticle to remain at the exact same overall size relative to the level of zoom being used. The end result is that the reticle measurements alter based upon the magnification chosen to shoot over greater distances because the reticle measurements present different increments which can vary with the magnification level. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular kinds of optics work for:
- Long distance forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots occur within shorter ranges and spaces
- Shooters who want a clearer optic picture with less space used up by the enlarged FFP reticle
About Rifle Optic Zoom
The quantity of zoom a scope offers is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Fixed Power Lens Optics
A single power rifle scope comes with a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust given that it is set from the factory.
Info About Variable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. It will list the zoom amount in a format like 2-10×32. These numbers mean the magnification of the scope can be changed between 2x and 10x power. This always involves the power levels in-between 2 and 10. The power shift is accomplished by operating the power ring part of the scope near the back of the scope by the eye bell piece.
Power Levels and Range Correlations
Here are some suggested scope power settings and the distances where they may be efficiently used. Highly magnified rifle scope glass will not be as beneficial as lower powered optics considering too much zoom can be a bad thing. The same idea relates to extended ranges where the shooter needs enough power to see where to properly aim the rifle at the target.
Lens Covering for Scopes
All modern rifle glass lenses are covered. Lens coating is a vital aspect of a rifle when looking into high end rifle optics and scope systems.
ED Versus HD Scopes
Some scope producers also use “HD” or high-definition lens coatings which use various techniques, aspects, chemicals, and polarizations to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Glass Lens Covering Versus Multi-Coating
Various optic lenses can also have various coverings applied to them. All lenses typically have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” coated. Being “much better” depends on the producer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Hydrophobic Lens Coatings
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Many top of the line and military grade optic companies will coat their lenses with a hydrophobic or hydrophilic anti-water covering.
Rifle Glass Mounting Alternatives
Installing options for scopes are available in a few choices. There are the standard scope rings which are separately installed to the optic 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 shooters to quickly mount and remove the scopes.
Hex Key Glass Rings
Normal, clamp design 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 separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope mount is great for rifles which need a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle. Several scopes can also be swapped out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping precision. These types of mounts come in convenient for shooting platforms which are carried a lot, to take off the optic from the rifle for protection, or for sight systems which are utilized in between multiple rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It normally costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle scope can spoil a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope’s tube. Most scopes protect against humidity from entering the scope tube with a series of sealing O-rings which are waterproof. Typically, these water-resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample wetness prevention for common use rifles for hunting and sporting purposes, unless you intend on taking your rifle on boats and are concerned about the optic still functioning if it is submerged in water and you can still rescue the rifle.
Gas Purged Rifle Glass Tubes
Another component of avoiding the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the scope is less influenced by condition alterations and pressure variations from the outside environment which could potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
