What You Need to Know About Rifle Scopes
Rifle scopes permit you to specifically align a rifle at various targets by aligning your eye with the target at range. They do this through magnifying the target by employing a series of lenses within the scope. The scope’s alignment can be dialed in for consideration of separate environmental things like wind 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 viewing via the optic as you line up the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle optics have about 11 parts which are found internally and outside of the scope body. These scope parts consist of the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other components. Learn about the eleven parts of optics.
About Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the optimal type of rifle glass is based around what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This triggers the reticle to increase in size based on the extent of zoom being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. For instance, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the corresponding tick at 100 yards with 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are marginal
- Experienced shooters who understand their aim point “hold over” plus “lead” ratios for their firearm
- Shooters who do not mind the reticle is enlarged and requires more visual sight space than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Far away types of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and proximities
- Shooters who like a clearer optic picture without area taken up by the enlarged FFP reticle
Ins and Outs of Scope Zoom
The quantity of magnification a scope offers is identified by the diameter, 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 Optic Details
A single power rifle optic will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate because it is fixed.
About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be modified between magnified levels. The power adjustment is accomplished by the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Glass
Here are some advised scope powers and the ranges where they can be successfully used. Highly magnified scopes will not be as efficient as lower magnification level glass since too much zoom can be a negative aspect depending on your shooting distance. The exact same concept relates to extended distances where the shooter needs increased power to see where to properly aim the rifle.
Rifle Optic Lens Covering
All modern-day rifle optic lenses are coated. There are different types and qualities of glass lens finishings. When considering high end rifle optical units, Lens finishing can be a very important element of defining the rifle’s capability. The glass lenses are one of the most significant parts of the scope as they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses offers protection to the lens surface as well as helps with anti glare from excess natural light and color presence.
HD Versus ED Lenses
Some rifle scope producers even use “HD” or high-def glass coatings that take advantage of different procedures, polarizations, chemicals, and aspects to enhance a wide range of color ranges and viewable definition through lenses. This HD finishing is frequently used with increased density lens glass which brings down light’s ability to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how certain colors are represented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be noticeable around objects with well defined shapes as light hits the object from certain angles.
Single Rifle Scope Lens Finish Versus Multi-Coating
Different optic lenses can likewise have different coverings used to them. All lenses usually have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” covered. This means the lens has multiple treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can indicate that a producer is taking several actions to combat different natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This additionally doesn’t always imply the multi-coated lens will perform better than a single covered lens. Being “better” depends on the manufacturer’s lens treatment solutions and the quality of materials used in constructing the rifle optic.
Anti-water Rifle Glass Lens Coating
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Many top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic coating.
Rifle Glass Mounting Alternatives
Installing solutions for scopes can be found in a couple of options. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also typically can be found in quick release variations which use toss levers which permit rifle operators to quickly mount and remove the optics.
Rifle Optic Mounting Solutions with Hex Key Rings
Basic, clamp type mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use double separate rings to support the scope, and are usually 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 rifles which need to have a resilient, rock solid mount which will not move regardless of just how much the scope is moved or jarring the rifle takes. These are the design of mounts you should get for a dedicated optics system on a long distance hunting or competitors firearm which will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the mount’s screws to stop the hex screw threads from wiggling out after they are mounted securely in position. An example of these mounting rings are the 30mm type from Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. Multiple scopes can also be switched out if they all use a similar style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top type 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 preserving the original sighting settings. These kinds of mounts are useful and convenient for rifles which are carried a lot, to take off the optic from the rifle for protection, or for scopes which are used between multiple rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It usually costs around $250 USD
Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. The majority of scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Optic Tubes
Another component of avoiding the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the scope is less affected by temperature level changes and pressure variations from the outdoor environment which may possibly permit water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
