Info Rifle Scopes
Rifle scopes enable you to precisely align a rifle at different targets by aligning your eye with the target over a distance. They do this through magnification by using a series of lenses inside the scope. The scope’s positioning can be adapted to take into account many ecological things like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the target. A lot of contemporary rifle scopes and optics have about 11 parts which are located internally and on the exterior of the scope. These scope parts include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other parts. Learn about the eleven parts of optics.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Going for the best type of rifle scope depends on what type of shooting you plan to do.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” equations for their firearm
- Shooters who do not mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Scope Details
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 measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots happen within shorter distances and ranges
- Shooters who select a clearer optic sight picture with less space taken up by the bigger FFP reticle
Magnification for Rifle Glass
The level of scope magnification you need on your glass is based on the type of shooting you like to do. Nearly every kind of rifle optic delivers some level of zoom. The quantity of magnification a scope supplies is determined by the diameter, thickness, and curvatures of the lens glass within the rifle optic. The magnification of the optic is the “power” of the scope. This suggests what the shooter is observing through the scope is amplified times the power factor of what can usually be seen by human eyes.
Info on Single Power Lens Optics
A single power rifle 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 optic can not change since it is a set power scope.
Variable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom amount in a format such as 2-10×32. These numbers mean the zoom of the scope could be changed in between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power adaptation is achieved by operating the power ring component of the scope near the back of the scope by the eye bell piece.
Scope Power and Range Correlation
Here are some suggested scope power levels and the distances where they could be effectively used. High power rifle scope glass will not be as efficient as lower magnification level rifle scope glass since too much zoom can be a bad thing. The very same idea relates to longer ranges where the shooter needs to have increased power to see exactly where to best aim the rifle.
Optic Lens Coating
All current rifle scope lenses are coated. Lens finishing can be an essential aspect of a shooting system when thinking about high end rifle optics and scope systems.
Info on Rifle Scope Lens Coatings – HD Versus ED
Some optic producers additionally use “HD” or high-def lens coatings which make the most of different procedures, chemical applications, polarizations, and elements to extract a wide range of color ranges and viewable definition through the lens. This high-def covering is normally used with higher density glass which drops light’s potential to refract through the lens glass. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration is often obvious over things with defined outlines as light hits the object from various angles.
Single Covering Versus Multi-Coating for Rifle Optics
Various scope lenses can also have different finishings applied to them. All lenses generally have at least some kind of treatment or covering applied to them before they are used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally functional in lots of types 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 minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope makers similarly make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the maker’s lens treatment technology and the quality of products used in constructing the rifle scope.
Hydrophobic Covering for Rifle Glass
Water on a lens does not support preserving a clear sight picture through a scope whatsoever. Numerous top of the line or high-end scope makers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the surface area of the Steiner scope lens so the H2O particles can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Optic Mounting Alternatives
Mounting solutions for scopes can be found in a few options. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also typically can be found in quick release versions which use manual levers which enable rifle shooters to quickly mount and dismount the glass.
Rifle Glass Mounts with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These forms of scope mounts use double detached rings to support the optic, and are normally made from 7075 T6 billet aluminum which are created for far away accuracy shooting. This type of scope mount is effective for rifle systems which are in need of a durable, hard use mount which will not move regardless of how much the scope is moved or jarring the rifle takes. These are the style of mounts you should get for a faithful optics system on a far away hunting or sniper competition rifle which will pretty much never need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on screws to prevent the hex screw threads from backing out after they are installed safely in position. An example of these rings are the 30mm style from Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Optic Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can often be swapped 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 type Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping accuracy. These types of mounts are useful and beneficial for shooting platforms which are moved a lot, to take off the optic from the rifle for protection, or for optics which are utilized in between multiple rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It generally costs around $250 USD
Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your costly optic by bringing about fogging and creating residue inside of the scope tube. A lot of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Optic Tubes
Another part of preventing the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the scope is less impacted by climate changes and pressure distinctions from the outside environment which may possibly allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
