Rifle Optic Info
Rifle scopes allow you to exactly aim a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through magnifying the target by employing a set of lenses inside the scope. The scope’s alignment can be adjusted for consideration of numerous ecological things like wind speed and elevation increases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the target. Many modern rifle scopes and optics have around 11 parts which are found within and on the exterior of the optic. These optic pieces include the rifle scope’s body, lenses, windage and elevation dials, focus rings, and other parts. See all eleven parts of optics.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has decides where the reticle or crosshair lies in relation to the optic’s magnifying adjustments. It simply means the reticle is situated behind or in front of the magnifying lens of the optic. Considering the most desired type of rifle glass is based upon what form of hunting or shooting you plan on doing.
About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting situations where computations are minimal
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” equations for their long gun
- Shooters who don’t mind the reticle is bigger and requires more visual sight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick.
- Far away kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who desire a clearer optic sight picture with less space taken up by the enlarged FFP reticle
Rifle Scope Zoom
The quantity of zoom a scope offers is figured out 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 Scopes
A single power rifle scope will have a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate since it is a fixed power scope.
Variable Power Lens Scopes
Variable power rifle scopes can be adjusted between magnification power levels. These types of scopes will list the magnification degree in a format such as 2-10×32. These numbers suggest the zoom of the scope could be set in between 2x and 10x power. This additionally utilizes the powers in-between 2 and 10. The power adaptation is accomplished by employing the power ring component of the scope near the back of the scope by the eye bell piece.
Glass Power and Range Correlation
Here are some suggested scope power levels and the distances where they could be successfully used. High power rifle scope glass will not be as efficient as lower magnification level rifle scope glass considering too much zoom can be a bad thing. The same relates to extended distances where the shooter needs sufficient power to see exactly where to best aim the rifle at the target.
Lens Covering for Rifle Glass
All modern-day rifle optic lenses are covered in special coatings. There are various types and qualities of lens coatings. Lens finishing can be an important element of a rifle when considering high end rifle optics and scope units. The glass lenses are one of the most crucial components of the scope given that they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses shields the lens surface area and even improves anti glare capabilities from excess daylight and color discernibility.
Details on Lens Coatings – HD Versus ED
Some rifle glass producers will also use “HD” or high-def lens finishings which take advantage of different processes, polarizations, elements, and chemicals to enhance various color ranges and viewable target visibility through the lens. This high-def covering is frequently used with more costly high density lens glass which reduces light’s chance to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious around objects with well defined outlines as light hits the item from particular angles.
Single Rifle Glass Lens Covering Versus Multi-Coating
Various optic lenses can likewise have different coatings used to them. All lenses typically have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Rifle Optic Lens Hydrophobic Finish
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic covering which is water repellent.
Alternatives for Installing Optics on Long Guns
Installing options for scopes come in a few options. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also normally are made in quick release variations which use toss levers which enable rifle shooters to rapidly install and remove the scope.
Rifle Optic Mounting Solutions with Hex Key Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation 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 are developed for long range accuracy shooting. This type of scope install is fine for rifles which require a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Glass Ring Mounting Solutions
These types 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 design mount, multiple scopes can also be swapped in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining the original sighting settings. These kinds of mounts are useful and practical for shooting platforms which are transferred a lot, to take off the scope glass from the rifle for protection, or for optics which are used between numerous rifles. An example of this mount type is the 30mm mount from Vortex Optics. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle scope can mess up a day of shooting and your costly optic by triggering fogging and developing 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.
Rifle Scope Gas Purging
Another element of avoiding the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the scope is less affected by condition alterations and pressure distinctions from the external environment which could potentially permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
