Information About Rifle Optics
Rifle scopes enable you to specifically aim a rifle at various targets by lining up your eye with the target over a range. They do this through zoom using a set of lenses inside the scope. The scope’s positioning can be adjusted for the consideration of varied ecological considerations like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will land based on the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the target. A lot of contemporary rifle scopes have about 11 parts which are found inside and externally on the scope. These parts consist of the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other components. Learn about the eleven parts of optics.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The type of focal plane a scope has determines where the reticle or crosshair lies in regard to the optic’s zoom. It literally suggests the reticle is located behind or in front of the magnification lens of the optic. Selecting the most suitable style of rifle scope is based upon what kind of shooting or hunting you intend on undertaking.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who recognize their aim point “hold over” and “lead” correlations for their firearms
- Shooters who do not mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle to the rear of 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 reticle measurement.
- Far away kinds of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who choose a clearer optic sight picture without space taken up by the bigger FFP reticle
Rifle Glass Magnification
The extent of scope zoom you require depends upon the kind of shooting you choose to do. Just about every type of rifle scope delivers some level of zoom. The amount of magnification a scope delivers is established by the dimension, thickness, and curves of the lens glass within the rifle optic. The zoom of the scope is the “power” of the scope. This denotes what the shooter is observing through the scope is magnified times the power aspect of what can usually be seen by human eyes.
Fixed Power Lens Scopes
A single power rifle scope or optic will have a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate since it is a fixed power scope.
Adjustable Power Lens Rifle Scope Info
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 mean the zoom of the scope can be changed in between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power adjustment is accomplished by applying the power ring component of the scope near the back of the scope by the eye bell.
The Power Level and Range of Optics
Here are some suggested scope powers and the distances where they may be effectively used. High power glass will not be as effective as lower powered scopes since too much zoom can be a negative aspect depending on your shooting distance. The exact same concept applies to longer distances where the shooter needs increased power to see precisely where to properly aim the rifle at the target.
Optic Lens Covering
All modern-day rifle optic lenses are coated. There are various types and qualities of glass lens finishes. When considering high end rifle targeting units, Lens finish can be a significant component of defining the rifle’s capability. The lenses are among the most important parts of the glass considering that they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses shields the lens exterior as well as helps with anti glare capabilities from excess sunrays and color presence.
HD Versus ED Lenses
Some scope makers also use “HD” or high-definition lens finishings which use various processes, chemicals, polarizations, and elements to draw out different colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Optic Lens Single Coating Versus Multi-Coating
Various optic lenses can even have various coverings applied to them. All lenses normally have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It must have a coating put on it so that the lens will be optimally usable in numerous types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can safeguard the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope maker and the amount you paid for it. Both the make and cost are indicators of the lens quality.
Some scope producers likewise make it a point to specify if their optic lenses are layered or “multi” covered. This indicates the lens has had multiple treatments applied to the surfaces of the glass. If a lens receives several treatments, it can establish that a maker is taking several steps to fight different natural factors like an anti-glare covering, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This also does not always indicate the multi-coated lens is better than a single layered lens. Being “much better” depends upon the manufacturer’s lens treatment techniques and the quality of glass used in constructing the rifle scope.
Anti-water Optic Lens Coating
Water on a lens does not assist with keeping 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 hydrophilic or hydrophobic coating.
Rifle Glass Installation Options
Mounting approaches for scopes are available in a few options. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally come in quick release variations which use toss levers which permit rifle operators to quickly mount and remove the glass.
Hex Key Glass Ring Mounts
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount 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 accuracy shooting. This type of scope install is fine for rifles which need a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be switched out if they all use a compatible design mount. These types of mounts are handy for rifle platforms which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles or are situationally focused.
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle optic can spoil a day on the range and your highly-priced optic by resulting in fogging and making residue inside of the scope tube. Many optics protect against moisture from going into the optical tube with a series of sealing O-rings which are water resistant. Normally, these water resistant optics can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture content avoidance for basic use rifles, unless you plan on taking your rifle on boats and are concerned about the optic still performing if it goes over the side and you can still recover the gun.
Gas Purged Optic Tubes
Another element of avoiding the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the glass is less impacted by temperature level shifts and pressure variations from the outside environment which might potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
