Rifle Optic Info
Rifle scopes enable you to precisely aim a rifle at different targets by lining up your eye with the target over a range. They accomplish this through zoom by employing a set of lenses inside the scope. The scope’s positioning can be adjusted to take into account varied ecological things like wind and elevation to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based upon the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes have around 11 parts which are found internally and externally on the optic. These scope parts include the rifle scope’s body, lenses, elevation dials or turrets, objective focus rings, and other components. Learn about the eleven parts of rifle scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the optimal type of rifle glass is based around what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This induces the reticle to increase in size based on the extent of zoom being used. The result is that the reticle measurements are the same at the enhanced range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at 100 yards by using 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are very little
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” relationships for their firearm
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. 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.
- Long distance forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots occur within shorter ranges and distances
- Shooters who want a clearer optic picture with less room used up by the larger sized FFP reticle
Optic Zoom
The amount of scope magnification you require depends upon the style of shooting you want to do. Virtually every type of rifle scope offers some level of magnification. The level of zoom a scope delivers is established by the diameter, thickness, and curvatures of the lens glass inside of the rifle scope. The magnification of the optic is the “power” of the scope. This implies what the shooter is checking out through the scope is magnified times the power element of what can generally be seen by human eyes.
Single Power Lens Optics
A single power rifle optic or scope comes with a magnification number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not adjust since it is set from the factory.
Adjustable Power Lens Scopes
Variable power rifle scopes use enhanced power. The power adjustment is achieved by the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Optics
Here are some advised scope power levels and the ranges where they may be effectively used. Highly magnified rifle scope glass will not be as effective as lower magnification level glass considering too much zoom can be a bad thing. The same concept goes for longer ranges where the shooter needs enough power to see exactly where to properly aim the rifle.
About Glass Lens Coatings
All state-of-the-art rifle optic lenses are layered. Lens finishing is a crucial aspect of a rifle’s setup when thinking about high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope producers likewise use “HD” or high-definition lens coatings which use various techniques, polarizations, components, and chemicals to draw out various colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Coating Versus Multi-Coating
Different optic lenses can also have various finishes used to them. All lenses normally have at least some type of treatment or covering used to them before being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope company and how much you spent paying for it. Both are indications of the lens quality.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” coated. This indicates the lens has numerous treatments applied to the surfaces of the glass. If a lens receives multiple treatments, it can show that a company is taking numerous steps to fight different natural elements like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This also doesn’t necessarily mean the multi-coated lens will perform much better than a single layered lens. Being “much better” depends upon the manufacturer’s lens treatment solutions and the quality of materials used in creating the rifle glass.
Anti-water Finishing for Scopes
Water on a scope lens does not improve retaining a clear sight picture through an optic whatsoever. Lots of top of the line and premium scope producers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior surfaces of the Steiner glass lens so the water particles can not bind to it or create surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Alternatives for Mounting Rifle Glass on Firearms
Installing options for scopes come in a few choices. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also generally can be found in quick release versions which use manual levers which enable rifle shooters to rapidly mount and remove the optics.
Hex Key Rifle Optic Rings
Normal, 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 two different rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long range precision shooting. This type of scope mount is perfect for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abused.
Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be switched out if they all use a similar style mount. These types of mounts are handy for rifle platforms which are transferred a lot, to remove the optic from the rifle for protection, or for optics which are used in between multiple rifles or are situationally focused.
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle scope can destroy a day of shooting and your costly optic by bringing about fogging and producing residue inside of the scope tube. A lot of scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Glass Gas Purging
Another component of preventing the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the optic is less influenced by climate alterations and pressure distinctions from the external environment which may possibly 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.
