About Rifle Scopes
Rifle scopes allow you to precisely aim a rifle at various targets by lining up your eye with the target at range. They do this through magnification by using a set of lenses within the scope. The scope’s alignment can be adjusted for consideration of many environmental elements like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the target. A lot of contemporary rifle scopes have about eleven parts which are found internally and on the exterior of the scope body. These scope parts consist of the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other elements. See all eleven parts of an optic.
About Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The sort of focal plane an optic has establishes where the reticle or crosshair lies in connection with the optic’s magnifying adjustments. It literally means the reticle is behind or ahead of the magnification lens of the optic. Picking the most ideal sort of rifle glass depends upon what kind of shooting you intend on undertaking.
First Focal Plane Optic Details
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where computations are minimal
- Experienced shooters who understand their target “hold over” and “lead” correlations for their rifles
- Shooters who don’t mind the reticle is bigger and occupies more visual sight area than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle behind 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 measurement.
- Far away forms of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots happen within shorter proximities and ranges
- Shooters who select a clearer optic picture without room taken up by the larger sized FFP reticle
Zoom for Optics
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 Power Lens Rifle Glass Details
A single power rifle optic and scope will have a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not change given that it is a fixed power optic.
Info on Adjustable Power Lens Optics
Variable power rifle scopes use variable power levels. The power modification is performed by making use of the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range Correlation of Glass
Here are some advised scope powers and the ranges where they could be efficiently used. Highly magnified glass will not be as beneficial as lower powered rifle scope glass considering too much zoom can be a bad thing. The same applies to longer distances where the shooter needs adequate power to see precisely where to best aim the rifle.
Info on Rifle Glass Lens Coverings
All modern-day rifle glass lenses are covered. Lens covering is a vital element of a shooting system when looking into high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope brands also use “HD” or high-definition lens finishings which use various processes, aspects, polarizations, and chemicals to draw out different 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 Finish Versus Multi-Coating for Rifle Glass
Various optic lenses can also have various coatings applied to them. All lenses usually have at least some kind of treatment or covering 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 finely tuned optic. It requires a coating to be applied to it so that the lens will be optimally usable in many types of environments, degrees of sunshine (full VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can preserve 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 on the scope company and how much you spent on it. The scope’s maker and cost are indicators of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are layered or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of products used in developing the rifle scope.
Hydrophobic Finish for Optics
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Many top of the line and high-end scope companies will coat their lenses with a hydrophobic or hydrophilic coating.
Options for Mounting Glass on Long Guns
Mounting options for scopes can be found in a few options. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These various types of mounts also usually can be found in quick release variations which use toss levers which enable rifle operators to rapidly mount and dismount the scope.
Hex Key Rifle Glass Ring Mounting Solutions
Standard, 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 a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope mount is great for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, multiple scopes can also be switched out in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining precision. These kinds of mounts come in handy for shooting platforms which are transferred a lot, to take off the optic from the rifle for protection, or for optics which are employed between numerous rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It generally costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle optic can mess up a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. The majority of scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Details on Glass Tube Gas Purging
Another element of avoiding the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the scope is less influenced by temp alterations and pressure distinctions from the external environment which may potentially 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 look for.
