Rifle Scope Information
Rifle scopes permit you to exactly aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnifying the target by using a set of lenses within the scope. The scope’s alignment can be adjusted for consideration of numerous ecological considerations like wind and elevation decreases to make up 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 viewing with the optic as you line up the scope’s crosshair or reticle with the target. Many contemporary rifle scopes and optics have around eleven parts which are arranged inside and on the exterior of the scope body. These optic pieces consist of the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other components. See all eleven parts of a rifle scope.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the optimal type of rifle scope is based around what type of shooting you plan on doing.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are low
- Experienced shooters who understand their aim point “hold over” and “lead” equations for their long guns
- Shooters who do not mind the reticle is bigger and uses up more visual eyesight room than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle behind the magnification lens. This causes the reticle to remain at the very same overall size in relation to the level of zoom being used. The result is that the reticle dimensions evolve based on the zoom used to shoot over greater distances considering the reticle measurements represent various increments which change with the magnification. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick. These particular types of scopes work for:
- Long distance kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who select a clearer optic picture without room used up by the larger sized FFP reticle
Ins and Outs of Rifle Scope Magnification
The measure of scope zoom you need on your optic depends upon the style of shooting you wish to do. Pretty much every style of rifle glass offers some level of zoom. The level of magnification a scope offers is identified by the size, thickness, and curvatures of the lens glass within the rifle scope. The magnifying level of the optic is the “power” of the opic. This suggests what the shooter is looking at through the scope is magnified times the power aspect of what can normally be seen by human eyes.
Info on Single Power Lens Rifle Glass
A single power rifle scope comes with a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not change considering that it is a fixed power scope.
Variable Power Lens Rifle Scope Info
Variable power rifle scopes have adjustable power. It will list the magnification level in a format like 2-10×32. These numbers imply the magnification of the scope can be changed between 2x and 10x power. This additionally incorporates the powers in-between 2 and 10. The power manipulation is achieved utilizing the power ring component of the scope near the rear of the scope by the eye bell.
Rifle Scope Power Level and Range Correlation
Here are some recommended scope powers and the ranges where they could be efficiently used. Always remember that high power optics and scopes will not be as effective as lower powered scopes since too much zoom can be a bad thing. The same relates to extended ranges where the shooter needs adequate power to see precisely where to properly aim the rifle at the target.
Lens Covering for Rifle Glass
All modern rifle scope lenses are covered in special coatings. There are various types and qualities of glass coverings. Lens coating is a crucial element of a rifle’s setup when considering high end rifle optics and targeting units. The lenses are among the most essential pieces of the optic as they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses offers protection to the lens exterior and also assists with anti glare capabilities from excess daylight and color perception.
HD Versus ED Rifle Optic Lens Coatings
Some scope makers additionally use “HD” or high-def lens coverings that make the most of various procedures, elements, rare earth compounds, and polarizations to enhance numerous color ranges and viewable target visibility through the lens. This high-definition finishing is commonly used with more costly, high density lens glass which lowers light’s ability to refract by means of the lens glass. Some scope vendors use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration can be obvious over things with hard outlines as light hits the item from specific angles.
Scope Lens Single Coating Versus Multi-Coating
Various optic lenses can also have different finishes applied to them. All lenses normally have at least some kind of treatment or finishing 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 simply a raw piece of glass. It is part of the finely tuned optic. It needs to have a coating placed on it so that it will be optimally functional in lots of kinds of environments, degrees of light (full 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 lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope designer and the amount you spent on it. Both the manufacturer and amount are indications of the lens quality.
Some scope manufacturers likewise make it a point to define if their optic lenses are coated or “multi” covered. This indicates the lens has numerous treatments applied to them. If a lens receives multiple treatments, it can prove that a maker is taking numerous actions to combat different environmental factors like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This additionally does not always suggest the multi-coated lens is better than a single covered lens. Being “much better” is dependent on the maker’s lens treatment innovation and the quality of components used in building the rifle optic.
Optic Lens Anti-water Finish
Water on a lens doesn’t assist with maintaining a clear sight picture through an optic in any way. Many top of the line or high-end optic makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It provides protection for the surface of the Steiner scope lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Alternatives for Installing Scopes on Long Guns
Mounting approaches for scopes can be found in a few choices. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also typically come in quick release versions which use throw levers which permit rifle shooters to quickly install and remove the glass.
Hex Key Rifle Scope Ring Mounts
Standard, clamp-on type mounting scope rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on rifles. These types of scope mounts use double independent rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are made for far away precision shooting. This kind of scope mount is effective for rifles which are in need of a long lasting, hard use mount which will not change despite how much the scope is moved about or abuse the rifle takes. These are the style of mounts you really want to have for a faithful optics setup on a reach out and touch someone scouting or tournament firearm that will almost never need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to protect against the hex screws from wiggling out after they are installed securely in place. An example of these mounting rings are the 30mm type from Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Optic 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. If they all use a similar design mount, several scopes can also be switched out. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining precision. These types of mounts are useful and handy for shooting platforms which are hauled around a lot, to remove the scope glass from the rifle for protection, or for sight systems which are adopted between several rifles. An example of this mount style is the 30mm mount from Vortex Optics. It generally costs around $250 USD
About Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can spoil a day of shooting and your expensive optic by triggering fogging and generating residue inside of the scope’s tube. Most scopes protect against wetness from entering the optical tube with a series of sealing O-rings which are water resistant. Typically, these water-resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample humidity avoidance for common use rifles, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still performing if it goes over the side and you can still rescue the rifle.
Gas Purged Scope Tubes
Another part of preventing the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the optic is less affected by temp shifts and pressure differences from the external environment which may potentially allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
