Facts About Rifle Optics
Rifle scopes enable you to precisely aim a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnification by employing a set of lenses inside the scope. The scope’s positioning can be dialed in for consideration of separate ecological elements like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle scopes have around 11 parts which are found within and on the exterior of the scope body. These scope parts include the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other components. See all eleven parts of optics.
The Types 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 in regard to the optic’s zoom. It literally means the reticle is located behind or before the magnifying lens of the scope. Picking the most desired form of rifle scope is based upon what kind of shooting you plan on undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are minor
- Experienced shooters who know their target “hold over” and also “lead” equations for their firearm
- Shooters who don’t mind the reticle is bigger and occupies more visual sight room than a SFP reticle
Second Focal Plane Glass Info
Second focal plane optics (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away styles of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots take place within shorter spaces and ranges
- Shooters who select a clearer optic sight picture without area used up by the larger size FFP reticle
Details on Scope Zoom
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.
About Fixed Single Power Lens Optics
A single power rifle scope uses a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not fluctuate considering that it is a set power scope.
Adjustable Power Lens Optics
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom amount in a format like 2-10×32. These numbers imply the magnification of the scope could be changed between 2x and 10x power. This always involves the powers in-between 2 and 10. The power modification is achieved by applying the power ring component of the scope near the back of the scope by the eye bell.
The Power and Range of Rifle Optics
Here are some advised scope power settings and the distances where they may be effectively used. High power glass will not be as useful as lower magnification glass considering too much zoom can be a bad thing. The very same idea relates to longer distances where the shooter needs to have sufficient power to see where to properly aim the rifle.
About Glass Lens Finish
All modern-day rifle optic lenses are covered in special coatings. There are different types and qualities of glass coverings. When thinking about luxury rifle scope setups, Lens finishing can be a crucial aspect of a rifle. The lenses are among the most key components of the optic considering that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses safeguards the lens surface and assists with anti glare capabilities from excess natural light and color perception.
HD Versus ED Lenses
Some scope producers also use “HD” or high-definition lens coatings which use different procedures, polarizations, chemicals, and aspects to draw out various colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Optic Lens Finish 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 coating applied to them prior to being used in a rifle scope or optic. 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 needs to have a coating applied to it so that it will be optimally functional in many types of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are covered or “multi” coated. This implies the lens has had numerous treatments applied to them. If a lens receives several treatments, it can indicate that a manufacturer is taking several actions to fight various natural aspects like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This additionally doesn’t always indicate the multi-coated lens will perform much better than a single covered lens. Being “much better” hinges on the manufacturer’s lens treatment techniques and the quality of materials used in developing the rifle scope.
Info on Hydrophobic Finish
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 military grade optic companies will coat their lenses with a hydrophobic or hydrophilic anti-water finish.
Options for Installing Optics on Firearms
Mounting approaches for scopes can be found in a few options. There are the standard scope rings which are separately installed 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 permit rifle shooters to rapidly mount and dismount the glass.
Hex Key Rifle Glass Ring Mounts
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which is 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 abused.
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, multiple scopes can often be switched out on the range. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach solidly 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 preserving precision. These types of mounts come in beneficial for shooting platforms which are carried a lot, to take off the glass from the rifle for protection, or for aiming systems which are used between several rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle optic can ruin a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. Most scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Optic Gas Purging
Another element of avoiding the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the optic is less influenced by temperature level changes and pressure variations from the outdoor environment which might possibly enable water vapor to permeate 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.
