Rifle scopes allow you to specifically aim a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnification by using a set of lenses within the scope. The scope’s positioning can be dialed in for the consideration of many environmental considerations like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle scopes have about eleven parts which are located internally and on the exterior of the scope. These scope parts consist of the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other components. See all eleven parts of optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the optimal type of rifle glass is based around what type of shooting you plan on doing.
First Focal Plane Optic Info
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This induces 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 enhanced range as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at one hundred yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are minimal
- Experienced shooters who understand their aim point “hold over” plus “lead” equations for their firearm
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight area than a SFP reticle
Second Focal Plane Glass Info
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Long distance types of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots occur within much shorter spaces and ranges
- Shooters who like a clearer optic sight picture with less space taken up by the bigger FFP reticle
The measure of scope zoom you need on your glass depends on the sort of shooting you choose to do. Just about every kind of rifle optic provides some degree of zoom. The quantity of magnification a scope provides is determined by the diameter, density, and curves of the lenses within the rifle optic. The magnification of the scope is the “power” of the scope. This signifies what the shooter is checking out through the scope is magnified times the power factor of what can generally be seen by human eyes.
Single Power Lens Glass Facts
A single power rifle optic uses a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not fluctuate since it is a fixed power scope.
Adjustable Power Lens Glass Info
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom degree in a configuration such as 2-10×32. These numbers indicate the zoom of the scope can be set between 2x and 10x power. This additionally involves the power levels in-between 2 and 10. The power manipulation is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell piece.
The Power and Range of Scopes
Here are some suggested scope power settings and the distances where they may be effectively used. Remember that higher magnification scopes will not be as effective as lower magnification level optics since too much magnification can be a detractor. The very same idea applies to longer distances where the shooter needs sufficient power to see exactly where to best aim the rifle.
Info on Lens Covering
All modern rifle scope lenses are layered. There are various types and qualities of finishes. Lens coating can be a crucial element of a rifle when thinking about luxury rifle optics and scope units. The glass lenses are among the most critical pieces of the scope since they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens surface and assists with anti glare capabilities from refracted daylight and color visibility.
ED Versus HD Optics
Some scope manufacturers also use “HD” or high-definition lense coverings that take advantage of different procedures, polarizations, elements, and chemicals to enhance a wide range of color ranges and viewable definition through lenses. This high-definition finishing is often used with more costly, high density lens glass which brings down light’s chance to refract by means of the lens glass. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be obvious around objects with well defined outlines as light hits the item from specific angles.
What to Know About Single Finishing Versus Multi-Coating
Various scope lenses can also have different finishings applied to them. All lenses usually have at least some type of treatment or finish applied to them before being used in a rifle scope or optic assembly. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It needs to have a finishing put on it so that the lens will be optimally usable in lots of kinds of environments, degrees of sunshine (full VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can shield the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends on the scope producer and just how much you spent on it. Both are indicators of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Anti-water Covering for Scopes
Water on a lens doesn’t help with preserving a clear sight picture through a scope in any way. Numerous top of the line or high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the surface area of the Steiner glass lens so the H2O molecules can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Options for Installing Scopes on Firearms
Mounting options for scopes come in a couple of options. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally can be found in quick release versions which use throw levers which permit rifle operators to rapidly install and remove the scopes.
Optic Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These kinds of scope mounts use two individual rings to support the optic, and are made 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 need to have a resilient, unfailing mount which will not change no matter just how much the scope is moved about or abuse the rifle takes. These are the design of mounts you really want to have for a faithful optics setup on a far away scouting or hard target interdiction rifle that will almost never need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount’s screws to protect against the hex screw threads from wiggling out after they are installed safely in place. An example of these rings are the 30mm type from the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, multiple scopes can also be switched out. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping precision. These kinds of mounts are useful and practical for shooting platforms which are transferred between vehicles a lot, to remove the scope from the rifle for protection, or for sight systems which are chosen for use between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle scope can mess up a day of shooting and your costly optic by bringing about fogging and producing residue inside of the scope tube. Many scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Scope Gas Purging
Another element of avoiding the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the glass is less impacted by temp changes and pressure differences from the outside environment which may potentially allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
