Scope Info
Rifle scopes permit you to exactly aim a rifle at different targets by aligning your eye with the target at range. They do this through zoom by utilizing a set of lenses within the scope. The scope’s alignment can be dialed in for consideration of different ecological factors like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based on the sight picture you are seeing via the scope as you align the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle optics have around 11 parts which are arranged within and on the exterior of the scope body. These scope parts include the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other elements. See all eleven parts of an optic.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the optimal type of rifle scope is based on what type of shooting you plan to do.
About First Focal Plane Optics
First focal plane scopes (FFP) come with the reticle ahead of the zoom lens. This causes the reticle to increase in size based on the extent of zoom being used. The benefit is that the reticle measurements are the same at the enhanced distance as they are at the non magnified distance. For example, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where estimations are minimal
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” equations for their long gun
- Shooters who do not mind the reticle is enlarged and takes up more visual sight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle behind the magnifying lens. This triggers the reticle to stay at the same size relative to the quantity of magnification being used. The outcome is that the reticle measurements change based on the magnification employed to shoot over longer ranges considering that the reticle markings present distinct increments which can vary with the zoom level. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular varieties of scopes are useful for:
- Far away forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots occur within shorter spaces and ranges
- Shooters who prefer a clearer optic picture without room taken up by the larger size FFP reticle
Ins and Outs of Optic Zoom
The amount of scope magnification you need on your scope depends on the kind of shooting you wish to do. Almost every style of rifle scope offers some amount of zoom. The quantity of magnification a scope offers is determined by the size, density, and curvatures of the lenses within the rifle scope. The magnifying level of the scope is the “power” of the opic. This indicates what the shooter is aiming at through the scope is amplified times the power element of what can usually be seen by human eyes.
Fixed Single Power Lens Glass Facts
A single power rifle optic and scope will have a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not adjust considering that it is a fixed power optic.
Adjustable Power Lens Scopes
Variable power rifle scopes can be modified between magnified levels. The power modification is accomplished by using the power ring part of the scope near the back of the scope by the eye bell.
Optic Power and Range Correlation
Here are some advised scope powers and the ranges where they may be effectively used. High power scopes will not be as efficient as lower magnification level optics due to the fact that too much zoom can be a negative aspect depending on your shooting distance. The same goes for extended ranges where the shooter needs enough power to see where to properly aim the rifle.
About Lens Finishes
All modern rifle optic and scope lenses are covered in special coatings. There are various types and qualities of glass coatings. Lens covering is an important aspect of a rifle when thinking about high-end rifle optics and scope systems. The lenses are among the most vital components of the scope because they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses protects the lens exterior and helps with anti glare capabilities from refracted light and color presence.
HD Versus ED Lenses
Some scope manufacturers likewise use “HD” or high-definition lens finishes which use different procedures, chemicals, polarizations, and components to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Rifle Scope Lens Single Finish Versus Multi-Coating
Different scope lenses can also have different coatings applied to them. All lenses usually have at least some kind of treatment or finish applied to them before 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 carefully tuned optic. It must have a covering placed on it so that it will be efficiently usable in many types of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope manufacturer and just how much you spent paying for it. Both the make and cost are signs of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are layered or “multi” coated. This means the lens has multiple treatments applied to the surfaces. If a lens gets several treatments, it can indicate that a producer is taking multiple steps to combat different environmental aspects like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This additionally does not necessarily mean the multi-coated lens is much better than a single covered lens. Being “much better” depends on the producer’s lens treatment techniques and the quality of glass used in developing the rifle scope.
Glass Lens Anti-water Finishing
Water on a scope’s lens doesn’t help with preserving a clear sight picture through an optic in any way. Lots of top of the line and high-end optic producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It provides protection for the surface of the Steiner glass lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Choices for Mounting Rifle Glass on Firearms
Installing options for scopes are available in a couple of options. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also generally can be found in quick release variations which use manual levers which permit rifle shooters to rapidly install and remove the optics.
Scope Mounting Solutions with Hex Key Rings
Basic, clamp design mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These forms of scope mounts use double individual rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are created for far away precision shooting. This form of scope mount is excellent for rifle systems which require a resilient, hard use mount which will not move regardless of just how much the scope is moved or abuse the rifle takes. These are the style of mounts you want for a devoted scope system on a far away hunting or competition rifle which will almost never need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to protect against the hex screws from wiggling out after they are mounted safely in position. An example of these mounting rings are the 30mm type from the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a compatible design mount. These types of mounts are convenient for long guns which are carried a lot, to swap out the optic from the rifle for protection, or for scopes which are used between several rifles.
Info on Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day on the range and your expensive optic by resulting in fogging and producing residue within the scope’s tube. Most optics protect against wetness from entering the optical tube with a series of sealing O-rings which are water resistant. Generally, these water-resistant scopes can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture content prevention for standard use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on a boat and are concerned about the optic still working if it is submerged in water and you can still recover the gun.
Gas Purged Glass Tubes
Another component of avoiding the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the optic is less altered by climate shifts and pressure distinctions from the outside environment which might potentially permit water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
