All About Scopes
Rifle scopes allow you to exactly aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target using a set of lenses within the scope. The scope’s positioning can be adjusted for the consideration of different natural factors like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing with the optic as you align the scope’s crosshair or reticle with the target. Most contemporary rifle scopes have around eleven parts which are arranged within and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other components. Learn about the eleven parts of rifle optics.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the finest type of rifle scope depends on what type of shooting you plan on doing.
First Focal Plane Optic Info
First focal plane scopes (FFP) include the reticle ahead of the magnification lens. This induces 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 enhanced range as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the same tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who have an idea for their target “hold over” and “lead” equations for their firearm
- Shooters who don’t mind the reticle is bigger and uses up more visual sight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots happen within much shorter ranges and spaces
- Shooters who desire a clearer optic picture with less area used up by the enlarged FFP reticle
About Glass Magnification
The amount of magnification a scope supplies is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Glass
A single power rifle scope will have a magnification 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 optic can not adjust since it is fixed.
Info on Variable Power Lens Scopes
Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will note the magnification level in a configuration such as 2-10×32. These numbers indicate the magnification of the scope could be changed between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power adaptation is achieved by working with the power ring part of the scope near the rear of the scope by the eye bell piece.
Rifle Scope Power Level and Range Correlation
Here are some recommended scope powers and the ranges where they may be effectively used. Bear in mind that high magnification glass will not be as effective as lower powered optics and scopes since increased magnification can be a negative thing in certain situations. The exact same concept applies to extended ranges where the shooter needs to have increased power to see where to properly aim the rifle at the target.
Details on Rifle Scope Lens Finish
All contemporary rifle scope lenses are covered in special coatings. There are different types and qualities of glass lens coverings. Lens finish can be a crucial element of a rifle’s setup when looking at high-end rifle optics and scope units. The glass lenses are one of the most key pieces of the scope because they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses safeguards the lens surface and improves anti glare capabilities from excess sunshine and color visibility.
HD Versus ED Optic Lens Coatings
Some scope producers likewise use “HD” or high-definition lens coverings which use various procedures, components, polarizations, and chemicals to draw out different colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Details on Single Coating Versus Multi-Coating
Various scope lenses can even have different finishings applied to them. All lenses typically have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic assembly. This is because the lens isn’t just a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be optimally usable in numerous kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can safeguard the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope company and just how much you paid for it. The scope’s maker and cost are indicators of the lens quality.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” covered. This implies the lens has had several treatments applied to the surfaces of the glass. If a lens receives multiple treatments, it can establish that a company is taking multiple actions to fight various environmental elements like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This also doesn’t necessarily mean the multi-coated lens is much better than a single covered lens. Being “better” depends on the producer’s lens treatment techniques and the quality of products used in developing the rifle optic.
Hydrophobic Lens Finishes
Water on a scope’s lens doesn’t help with preserving a clear sight picture through an optic whatsoever. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the surface of the Steiner scope lens so the H2O molecules can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Rifle Scope Installing Choices
Installing solutions for scopes can be found in a couple of choices. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also generally can be found in quick release versions which use throw levers which allow rifle shooters to rapidly mount and remove the optics.
Hex Key Optic Ring Mounting Solutions
Standard, clamp-on type mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use a pair of individual rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are developed for far away precision shooting. This form of scope mount is very good for rifles which need a long lasting, rock solid mount which will not change no matter just how much the scope is moved about or abuse the rifle takes. These are the style of mounts you should get for a devoted scope setup on a long distance hunting or interdiction long gun which will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to prevent the hex screw threads from backing out after they are installed tightly in position. An example of these rings are the 30mm style made by the Vortex Optics company. The set typically costs around $200 USD
Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. If they all use a comparable style mount, multiple scopes can also be switched in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top style 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 keeping the original sighting settings. These types of mounts are useful and beneficial for shooting platforms which are transported a lot, to remove the scope from the rifle for protection, or for sight systems which are employed in between numerous rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It typically costs around $250 USD
Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day on the range and your costly optic by resulting in fogging and developing residue within the scope tube. Many scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are water resistant. Typically, these water resistant optics can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient humidity prevention for conventional use rifles, unless you intend on taking your rifle boating and are concerned about the optic still functioning if it goes over the side and you can still salvage the firearm.
Info Around Rifle Scope Tube Gas Purging
Another part of preventing the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the optic is less influenced by temperature changes and pressure distinctions from the outside environment which could possibly permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
