Rifle Optic Info
Rifle scopes allow you to specifically aim a rifle at various targets by lining up your eye with the target over a range. They do this through magnifying the target by utilizing a set of lenses inside the scope. The scope’s alignment can be adapted to account for varied 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 hit based on the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes and optics have about eleven parts which are located internally and on the exterior of the scope. These scope parts include the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other parts. Learn about the eleven parts of glass.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Finding the finest type of rifle optic is based around what type of shooting you plan on doing.
About First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are low
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” ratios for their weapon
- Shooters who don’t mind the reticle is enlarged and requires more visual sight room than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane glass (SFP) come with the reticle to the rear of the magnification lens. This triggers the reticle to remain at the same size in relation to the volume of magnification being used. The effect is that the reticle dimensions alter based on the zoom employed to shoot over greater ranges since the reticle markings represent different increments which fluctuate with the magnification level. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular varieties of glass work for:
- Long distance styles of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots occur within much shorter ranges and proximities
- Shooters who want a clearer optic picture with less area taken up by the enlarged FFP reticle
Optic Zoom
The quantity of zoom a scope supplies is determined by the size, density, 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 Scopes
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 magnification of this type of optic can not change given that it is a fixed power scope.
Adjustable Power Lens Glass
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification degree 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 utilizes the power levels in-between 2 and 10. The power adjustment is accomplished by making use of the power ring component of the scope near the back of the scope by the eye bell.
The Power and Range of Scopes
Here are some recommended scope powers and the distances where they could be effectively used. Keep in mind that high magnification optics will not be as practical as lower powered optics and scopes because too much zoom can be a bad thing. The same goes for longer ranges where the shooter needs enough power to see exactly where to properly aim the rifle at the target.
Details on Lens Covering
All contemporary rifle optic lenses are covered in special coatings. There are various types and qualities of lens coatings. When thinking about luxury rifle optical setups, Lens coating can be an essential component of defining the capability of the rifle. The lenses are among the most critical parts of the glass since they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses offers protection to the lens surface and helps with anti glare from excess sunrays and color visibility.
Info on Lens Coatings – HD Versus ED
Some scope brands likewise use “HD” or high-definition lens finishings which use various processes, chemicals, polarizations, and components to draw out separate colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Rifle Optic Lens Single Covering Versus Multi-Coating
Various optic lenses can likewise have different finishes applied to them. All lenses typically have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “much better” depends on the producer’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Anti-water Lens Coatings
Water on a lens doesn’t improve retaining a clear sight picture through a scope at all. Many top of the line or high-end optic producers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the exterior surfaces of the Steiner glass lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Choices for Mounting Glass on Firearms
Mounting approaches for scopes can be found in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also typically come in quick release versions which use throw levers which permit rifle operators to rapidly mount and dismount the optics.
Optic Mounting Solutions with Hex Key Rings
Basic, clamp-on design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These styles of scope mounts use two separate rings to support the scope, and are normally constructed from 7075 T6 billet aluminum which are manufactured for long distance precision shooting. This type of scope mount is great for rifle systems which are in need of a durable, hard use mount which will not move no matter just how much the scope is moved or abuse the rifle takes. These are the type of mounts you want for a dedicated optics setup on a reach out and touch someone scouting or competition long gun that will pretty much never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used to keep the hex screws from wiggling out after they are mounted tightly in position. An example of these mounting rings are the 30mm type made by Vortex Optics. The set usually costs around $200 USD
Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, a number of scopes can also be switched in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving precision. These types of mounts come in beneficial for shooting platforms which are shipped a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are utilized between several rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your costly optic by bringing about fogging and creating residue inside of the scope tube. Most scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Optic Tubes
Another part of avoiding the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the glass is less altered by temp alterations and pressure differences from the external environment which may possibly enable water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
