Rifle Scope Info
Rifle scopes allow you to exactly align a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through magnification by using a series of lenses inside the scope. The scope’s alignment can be dialed in for the consideration of different natural things like wind speed and elevation to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of contemporary rifle scopes and optics have about eleven parts which are located internally and outside of the scope body. These 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 optics.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The sort of focal plane an optic has establishes where the reticle or crosshair is located in connection with the optic’s magnifying adjustments. It literally suggests the reticle is located behind or ahead of the magnifying lens of the scope. Picking out the very best style of rifle scope is based on what type of hunting or shooting you anticipate doing.
First Focal Plane Scope Facts
First focal plane scopes (FFP) include the reticle in front of the magnifying lens. This causes the reticle to increase in size based upon the amount of magnification being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the identical tick at 100 yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are marginal
- Experienced shooters who understand their aim point “hold over” plus “lead” relationships for their weapon
- Shooters who do not mind the reticle is enlarged and takes up more visual sight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle to the rear of the magnifying lens. This triggers the reticle to remain at the same scale relative to the quantity of magnification being used. The outcome is that the reticle measurements adjust based on the zoom used to shoot over greater ranges given that the reticle markings represent various increments which vary with the zoom. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular styles of glass work for:
- Far away types of shooting where shooters have more time to make ballistic computations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who prefer a clearer optic sight picture without room used up by the larger size FFP reticle
The amount of zoom a scope offers is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Info About Fixed Power Lens Rifle Optics
A single power rifle optic will have a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not adjust considering that it is a fixed power scope.
About Variable Power Lens Rifle Scopes
Variable power rifle scopes use variable power levels. The power modification is handled by the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range of Optics
Here are some advised scope powers and the ranges where they may be effectively used. Highly magnified optics will not be as useful as lower magnification glass given that too much magnification can be a negative aspect depending on your shooting distance. The same idea relates to extended distances where the shooter needs to have adequate power to see exactly where to best aim the rifle.
Details on Lens Finishes
All modern-day rifle scope and optic lenses are coated. There are different types and qualities of lens finishes. When researching high end rifle optical setups, Lens coating can be a significant element of defining the rifle’s capability. The lenses are among the most critical parts of the optic as they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses offers protection to the lens exterior and improves anti glare from refracted daylight and color presence.
ED Versus HD Rifle Optics
Some glass makers also use “HD” or high-def lense finishings that use various processes, rare earth compounds, elements, and polarizations to draw out separate color ranges and viewable target definition through the lens. This high-definition finish is commonly used with increased density glass which lowers light’s capability to refract through the lens glass. Some scope corporations use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration can be visible over things with well defined shapes as light hits the item from specific angles.
Glass Lens Single Finishing Versus Multi-Coating
Various optic lenses can also have different coatings applied to them. All lenses usually have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope manufacturers similarly make it a point to specify if their optic lenses are coated or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in developing the rifle scope.
Anti-water Lens Finish
Water on a scope’s lens does not help with keeping a clear sight picture through an optic at all. Lots of top of the line and high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the exterior surfaces of the Steiner scope lens so the H2O particles can not bind to it or create surface tension. The outcome is that the water beads move off of the scope to preserve a clear, water free sight picture.
Options for Mounting Glass on Firearms
Mounting options for scopes are available in a couple of choices. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally can be found in quick release versions which use throw levers which permit rifle operators to rapidly install and dismount the optics.
Rifle Scope Mounts with Hex Key Rings
Normal, clamp style 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 a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope mount is great for rifles which need a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and attach it to a different rifle. Multiple scopes can even be swapped out if they all use a compatible design mount. These types of mounts are handy for long guns which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles.
About Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your expensive optic by inducing fogging and making residue within the scope tube. A lot of scopes protect against humidity from entering the optical tube with a system of sealing O-rings which are waterproof. Normally, these optics can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient moisture content avoidance for basic use rifles, unless you anticipate taking your rifle aboard watercrafts and are concerned about the scope still performing if it falls overboard and you can still salvage the firearm.
Rifle Scope Gas Purging
Another part of avoiding the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the glass is less altered by temp shifts and pressure differences from the outdoor environment which may possibly permit 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 look for.
