What You Need to Know About Rifle Scopes
Rifle scopes permit you to specifically aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnification by utilizing a series of lenses inside the scope. The scope’s alignment can be adjusted to account for many environmental elements like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based on the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle scopes and optics have around 11 parts which are arranged internally and on the exterior of the optic. These parts include the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other parts. See all eleven parts of an optic.
About Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the perfect type of rifle glass is based around what type of shooting you plan on doing.
First Focal Plane Scopes
First focal plane optics (FFP) feature the reticle in front of the zoom lens. This causes the reticle to increase in size based upon the amount of magnification being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at 100 yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting situations where calculations are low
- Experienced shooters who have an idea for their target “hold over” and also “lead” relationships for their firearm
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight area than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle behind 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 reticle measurement.
- Far away styles of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots occur within shorter spaces and ranges
- Shooters who like a clearer optic sight picture with less space taken up by the larger sized FFP reticle
Scope Magnification
The quantity of zoom a scope offers 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.
Single Power Lens Rifle Scope Facts
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 given that it is a set power scope.
About Adjustable Power Lens Glass
Variable power rifle scopes have adjustable power. It will note the zoom amount in a format such as 2-10×32. These numbers mean the zoom of the scope can be set between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power modification is achieved by operating the power ring component of the scope near the rear of the scope by the eye bell.
Scope Power Level and Ranges
Here are some advised scope power levels and the ranges where they could be successfully used. Always remember that high power scopes and optics will not be as practical as lower magnification level optics due to the fact that increased zoom can be a bad thing. The same idea relates to longer distances where the shooter needs to have sufficient power to see precisely where to properly aim the rifle at the target.
Info on Lens Coverings
All modern-day rifle scope and optic lenses are layered. There are different types and qualities of lens finishings. When thinking about luxury rifle scope setups, Lens finish can be a significant element of defining the capability of the rifle. The lenses are among the most crucial pieces of the optic because they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses shields the lens surface and also improves anti glare from refracted light and color visibility.
Info on Lens Coatings – HD Versus ED
Some optic producers even use “HD” or high-definition lens finishings which take advantage of different processes, chemical applications, polarizations, and components to extract various colors and viewable definition through the lens. This HD finishing is often used with more costly high density glass which decreases light’s chance to refract by means of the lens glass. Some scope suppliers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration is often obvious over things with hard outlines as light hits the object from various angles.
Single Finishing Versus Multi-Coating
Different optic lenses can likewise have different finishes used to them. All lenses typically have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope designer and just how much you spent on it. Both are indications of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in building the rifle scope.
Rifle Glass Lens Hydrophobic Finishing
Water on a lens does not improve maintaining a clear sight picture through an optic in any way. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the exterior surfaces of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The outcome is that the water beads move off of the scope to maintain a clear, water free sight picture.
Rifle Scope Mounting Choices
Mounting approaches for scopes come in a few options. There are the basic scope rings which are individually installed 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 variations which use toss levers which enable rifle shooters to rapidly mount and dismount the optics.
Rifle Optic Mounting Solutions with Hex Key Rings
Basic, clamp-on type mounting optic rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These varieties of scope mounts use a pair of detached rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are manufactured for far away precision shooting. This type of scope mount is very good for rifle systems which are in need of a resilient, hard use mount which will not change despite how much the scope is moved or abuse the rifle takes. These are the design of mounts you want for a dedicated optics setup on a reach out and touch someone hunting or competition firearm that will hardly ever 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 screw threads from backing out after they are installed tightly in place. An example of these rings are the 30mm style made by Vortex Optics. The set normally costs around $200 USD
Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and connect it to a different rifle. Multiple scopes can also be switched out if they all use a similar style mount. These types of mounts are convenient for long guns which are carried 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.
Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your costly optic by causing fogging and producing residue inside of the scope tube. Most scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are waterproof.
Glass Gas Purging
Another component of avoiding the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the optic is less altered by temperature level alterations and pressure differences from the outside environment which could possibly enable water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
