Optic Info
Rifle scopes allow you to specifically align a rifle at different targets by aligning your eye with the target over a range. They accomplish this through magnifying the target by employing a series of lenses inside the scope. The scope’s alignment can be adjusted to take into account numerous ecological things like wind speed and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended target. Many modern rifle optics have around 11 parts which are located within and outside of the optic. These scope parts include the rifle scope’s body, lenses, windage turrets, objective focus rings, and other elements. See all eleven parts of scopes.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the optimal type of rifle optic is based around what type of shooting you plan to do.
Info on First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This causes the reticle to increase in size based on the amount of zoom being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at one hundred yards by using 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are low
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” correlations for their rifles
- Shooters who don’t mind the reticle is bigger and uses up more visual sight room than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away styles of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who would like a clearer optic sight picture without room taken up by the bigger FFP reticle
Glass Zoom
The quantity of zoom a scope provides is determined 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.
Single Power Lens Rifle Optics
A single power rifle optic or scope comes with a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not fluctuate since it is set from the factory.
About Variable Power Lens Rifle Optics
Variable power rifle scopes can be tweaked between magnified settings. The power adjustment is handled by the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some suggested scope power levels and the ranges where they could be effectively used. Highly magnified scopes will not be as effective as lower powered glass due to the fact that too much magnification can be a bad thing. The same concept goes for longer distances where the shooter needs enough power to see precisely where to best aim the rifle at the target.
Rifle Glass Lens Finishing
All top teir rifle optic lenses are layered. Lens finish can be a crucial aspect of a rifle when purchasing high end rifle optics and scope systems.
Details on Lens Coatings – HD Versus ED
Some rifle scope suppliers also use “HD” or high-definition lense coatings that take advantage of various processes, rare earth compounds, aspects, and polarizations to enhance separate colors and viewable target definition through the lens. This HD finish is normally used with higher density glass which lowers light’s capability to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration can be visible over items with hard outlines as light hits the item from specific angles.
Single Covering Versus Multi-Coating
Various optic lenses can also have different coatings used to them. All lenses usually have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic.
This lens treatment can safeguard 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 layered lens depends on the scope producer and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” coated. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in developing the rifle scope.
About Hydrophobic Finishing
Water on a lens does not assist with keeping a clear sight picture through an optic whatsoever. Many top of the line or premium optic producers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It provides protection for the surface of the Steiner optic lens so the H2O particles can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Glass Installing Options
Mounting solutions for scopes are available in a couple of choices. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually come in quick release versions which use toss levers which allow rifle shooters to rapidly install and remove the optics.
Hex Key Optic Ring Mounts
Basic, clamp style mounting optic rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use two detached rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are made for long distance accuracy shooting. This kind of scope mount is very good for rifle systems which require a durable, unfailing mount which will not change regardless of just how much the scope is moved about or abuse the rifle takes. These are the style of mounts you should get for a faithful optics system on a reach out and touch someone hunting or competitors firearm that will hardly ever need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount screws to keep the hex screws from backing out after they are mounted safely in position. An example of these mounting rings are the 30mm style made by Vortex Optics. The set usually costs around $200 USD
Glass Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible design mount. These types of mounts are handy for long guns which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between numerous rifles or are situationally focused.
Info on Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your costly optic by inducing fogging and creating residue within the scope’s tube. A lot of optics protect against wetness from getting in the scope tube with a system 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 force moisture past the O-rings. This should be sufficient humidity avoidance for standard use rifles, unless you plan on taking your rifle on your motorboat and are worried about the scope still functioning if it goes over the side and you can still retrieve the rifle.
Gas Purged Rifle Glass Tubes
Another component of preventing the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the optic is less influenced by condition shifts and pressure distinctions from the outdoor environment which may potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
