Rifle Glass Information
Rifle scopes enable you to precisely align a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnification by making use of a series of lenses inside the scope. The scope’s alignment can be dialed in to account for different ecological things like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle scopes and optics have around 11 parts which are arranged inside and on the exterior of the scope. These parts include the rifle scope’s body, lenses, adjustment dials, focus rings, and other parts. Learn about the eleven parts of scopes.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane an optic has identifies where the reticle or crosshair is located in relation to the optic’s magnifying adjustments. It simply implies the reticle is behind or in front of the magnification lens of the scope. Picking out the most reliable style of rifle scope depends on what type of shooting you anticipate doing.
First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are very little
- Experienced shooters who know their target “hold over” as well as “lead” correlations for their long gun
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight area than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane optics (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Far away forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots occur within much shorter ranges and distances
- Shooters who like a clearer optic picture with less room taken up by the enlarged FFP reticle
About Rifle Optic Magnification
The quantity of zoom a scope supplies is identified by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Rifle Optics
A single power rifle scope or optic uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not fluctuate because it is a fixed power optic.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be tweaked between magnified levels. The power adjustment is performed by the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some suggested scope power levels and the distances where they can be effectively used. Highly magnified glass will not be as useful as lower magnification glass because too much magnification can be a bad thing. The exact same concept goes for longer distances where the shooter needs enough power to see exactly where to properly aim the rifle at the target.
Rifle Optic Lens Covering
All modern rifle scope lenses are coated. Lens coating can be an essential aspect of a rifle when looking into high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some rifle scope suppliers also use “HD” or high-definition lense finishings which make the most of various procedures, components, polarizations, and chemicals to extract various color ranges and viewable target definition through the lens. This high-def finish is commonly used with higher density glass which drops light’s ability to refract by means of the lens glass. Some scope corporations use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration may be visible over things with hard edges and shapes as light hits the item from certain angles.
Details on Single Coating Versus Multi-Coating
Different scope lenses can even have different finishings applied to them. All lenses generally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It needs to have a finishing put on it so that the lens will be efficiently functional in numerous types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can safeguard 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 maker and the amount you paid for it. Both the manufacturer and amount are indications of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the producer’s lens treatment innovation and the quality of products used in developing the rifle scope.
What to Know About Anti-water Finish
Water on a lens does not assist 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 hydrophobic or hydrophilic finish.
Options for Installing Optics on Firearms
Installing options for scopes are available in a few options. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally can be found in quick release versions which use manual levers which allow rifle operators to quickly install and dismount the scope.
Hex Key Optic Rings
Basic, clamp-on style mounting optic rings use hex head screws to position to the flattop design Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use double detached rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are developed for long distance accuracy shooting. This type of scope mount is good for rifles which require a resilient, unfailing mount which will not move no matter just how much the scope is moved or jarring the rifle takes. These are the style of mounts you should get for a specialized scope system on a far away hunting or interdiction firearm which will seldom need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount screws to prevent the hex screws from backing out after they are mounted securely in place. An example of these mounting rings are the 30mm style made by Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Glass 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. Multiple scopes can also be swapped out if they all use a similar designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining accuracy. These kinds of mounts are useful and beneficial for shooting platforms which are moved a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are utilized in between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle scope can mess up a day of shooting and your costly optic by bringing about fogging and producing residue inside of the scope tube. Many scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Rifle Optic Gas Purging
Another element of preventing the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the glass is less impacted by temperature changes and pressure differences from the outside environment which might 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 seek out.
