Scope Details
Rifle scopes allow you to specifically aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through zoom using a set of lenses within the scope. The scope’s alignment can be dialed in to account for varied environmental considerations like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based on the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle optics have about eleven parts which are found internally and on the exterior of the scope. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane an optic has identifies where the reticle or crosshair lies relative to the scopes magnifying adjustments. It literally implies the reticle is behind or ahead of the magnification lens of the scope. Selecting the best kind of rifle optic depends upon what type of shooting you anticipate undertaking.
First Focal Plane Glass
First focal plane optics (FFP) feature the reticle before the magnifying lens. This triggers the reticle to increase in size based on the level of magnification being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are very little
- Experienced shooters who know their target “hold over” plus “lead” correlations for their rifles
- Shooters who do not mind the reticle is bigger and uses up more visual sight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (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.
- Long distance types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots happen within shorter ranges and spaces
- Shooters who would like a clearer optic sight picture with less area taken up by the larger sized FFP reticle
Rifle Glass Magnification
The quantity of zoom a scope supplies 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.
About Fixed Power Lens Rifle Glass
A single power rifle scope and optic comes with a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust given that it is a set power scope.
Adjustable Power Lens Rifle Scope Facts
Variable power rifle scopes use enhanced power. The power adjustment is achieved using the power ring part of the scope near the back of the scope by the eye bell.
Rifle Glass Power Level and Ranges
Here are some advised scope power settings and the ranges where they may be successfully used. Highly magnified scopes will not be as efficient as lower magnification level rifle scope glass since too much zoom can be a negative aspect depending on your shooting distance. The exact same idea relates to longer ranges where the shooter needs to have adequate power to see where to properly aim the rifle at the target.
Optic Lens Finishing
All contemporary rifle optic and scope lenses are coated. There are different types and qualities of finishings. When researching high end rifle optical systems, Lens finish can be a critical component of defining the rifle’s capability. The lenses are one of the most significant components of the glass given that they are what your eye sees through while sighting a rifle in on the point of impact. The coating on the lenses shields the lens surface and even assists with anti glare capabilities from refracted sunlight and color presence.
Info on Lens Coatings – HD Versus ED
Some scope producers likewise use “HD” or high-definition lens finishes which use different procedures, polarizations, chemicals, and elements to draw out a wide range of colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Coating Versus Multi-Coating
Different optic lenses can even have various finishes applied to them. All lenses generally have at least some type of treatment or covering 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 is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally usable in numerous kinds of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This indicates the lens has several treatments applied to them. If a lens receives several treatments, it can prove that a manufacturer is taking numerous actions to fight various natural factors like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This also doesn’t necessarily imply the multi-coated lens will perform better than a single covered lens. Being “much better” hinges on the maker’s lens treatment innovation and the quality of products used in developing the rifle optic.
Hydrophobic Lens Coating
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic finish which is water repellent.
Optic Mounting Options
Installing options for scopes come in a couple of options. There are the basic scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally are made in quick release variations which use manual levers which permit rifle operators to rapidly mount and remove the glass.
Hex Key Rifle Optic Ring Mounts
Basic, clamp design mounting scope rings use hex head screws to position to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two individual rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are designed for far away precision shooting. This type of scope mount is good for rifle systems which are in need of a durable, rock solid mount which will not move despite how much the scope is moved about or jarring the rifle takes. These are the style of mounts you want for a faithful optics system on a far away scouting or interdiction rifle that will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount screws to prevent the hex screw threads from backing out after they are installed tightly in place. An example of these rings are the 30mm style from Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope and connect it to a different rifle. Several scopes can also be swapped out if they all use a similar style mount. These types of mounts are convenient for rifle platforms which are carried a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used in between multiple rifles or are situationally focused.
Info Around Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your costly optic by resulting in fogging and producing residue within the scope’s tube. Many scopes protect against humidity from entering the scope tube with a system of sealing O-rings which are water resistant. Typically, these water-resistant optics can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture content prevention for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle boating and are worried about the scope still working if it goes over the side and you can still find the rifle.
Gas Purged Rifle Scope Tubes
Another part of preventing the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the glass is less altered by condition shifts and pressure differences from the outdoor environment which may potentially permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
