What You Need to Know About Scopes
Rifle scopes permit you to precisely aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom by employing a series of lenses inside the scope. The scope’s positioning can be adjusted for the consideration of separate natural factors like wind speed and elevation to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the target. Most contemporary rifle optics have about 11 parts which are located within and on the exterior of the scope body. These scope parts include the rifle scope’s body, lenses, windage dials, objective focus rings, and other components. Learn about the eleven parts of rifle optics.
About Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the finest type of rifle scope is based on what type of shooting you plan to do.
First Focal Plane Optic Details
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are very little
- Experienced shooters who know their aim point “hold over” plus “lead” relationships for their firearm
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane glass (SFP) include the reticle behind the magnifying lens. This triggers the reticle to stay at the same scale in connection with the amount of magnification being used. The outcome is that the reticle dimensions shift based on the magnification chosen to shoot over lengthier distances due to the fact that the reticle measurements represent distinct increments which vary with the magnification level. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement. These sorts of glass work for:
- Far away forms of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who choose a clearer optic picture with less space used up by the larger size FFP reticle
Zoom for Rifle Glass
The extent of scope magnification you need is based on the type of shooting you desire to do. Pretty much every type of rifle optic offers some degree of magnification. The level of magnification a scope gives is identified by the size, density, and curvatures of the lens glass within the rifle optic. The magnification level of the optic is the “power” of the glass. This denotes what the shooter is aiming at through the scope is amplified times the power element of what can usually be seen by human eyes.
Single Power Lens Rifle Optic Info
A single power rifle scope and optic will have 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 type of optic can not change considering that it is a fixed power scope.
Adjustable Power Lens Glass
Variable power rifle scopes can be modified between magnified settings. The power change is achieved by using the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Glass Power Level and Ranges
Here are some recommended scope powers and the distances where they may be successfully used. Consider that high power scopes will not be as efficient as lower powered scope and optics since increased magnification can be a negative thing in certain situations. The very same idea applies to longer ranges where the shooter needs adequate power to see where to properly aim the rifle at the target.
Rifle Scope Lens Coating
All modern rifle optic lenses are coated. There are various types and qualities of glass lens finishings. Lens coating can be a crucial aspect of a rifle’s setup when considering high end rifle optics and targeting units. The lenses are one of the most vital components of the glass since they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses offers protection to the lens surface and also assists with anti glare capabilities from refracted light and color perception.
HD Versus ED Lenses
Some rifle glass manufacturers also use “HD” or high-definition glass finishings which take advantage of various processes, polarizations, aspects, and chemicals to enhance a wide range of color ranges and viewable target visibility through the lens. This high-def coating is typically used with higher density glass which drops light’s potential to refract through the lens glass. Some scope producers use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration is often obvious over items with well defined outlines as light hits the object from certain angles.
Single Rifle Scope Lens Finish Versus Multi-Coating
Different optic lenses can also have various coatings 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. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in lots of types of environments, degrees of light (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are coated or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
What to Know About Anti-water Finishing
Water on an optic’s lens does not improve preserving a clear sight picture through an optic in any way. Many 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 particles can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Choices for Installing Rifle Glass on Firearms
Mounting options for scopes can be found in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also typically are made in quick release versions which use throw levers which allow rifle shooters to quickly install and dismount the optics.
Hex Key Rifle Glass Ring Mounting Solutions
Basic, clamp-on design mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on rifles. These styles of scope mounts use two individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are made for long distance precision shooting. This type of scope mount is ideal for rifles which are in need of a resilient, hard use mount which will not move despite how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a devoted scope setup on a far away scouting or tournament long gun which will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used to keep the hex screw threads from wiggling out after they are mounted securely in position. An example of these rings are the 30mm type from the Vortex Optics company. The set generally costs around $200 USD
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, a number of scopes can also be swapped on the range. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten securely 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 while maintaining the original sighting settings. These kinds of mounts come in beneficial for shooting platforms which are transferred between vehicles a lot, to remove the optic from the rifle for protection, or for aiming systems which are utilized in between multiple rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. Most scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Rifle Glass Gas Purging
Another component of avoiding the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the optic is less affected by temp shifts and pressure distinctions from the external environment which might possibly enable 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 seek out.
