Facts About Rifle Optics
Rifle scopes permit you to exactly aim a rifle at various targets by lining up your eye with the target over a range. They do this through zoom by using a series of lenses inside the scope. The scope’s alignment can be adapted to account for different natural aspects like wind and elevation to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based upon the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the target. A lot of modern-day rifle scopes and optics have around 11 parts which are located internally and externally on the optic. These scope parts consist of the rifle scope’s body, lenses, windage turrets, focus rings, and other parts. 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 optics. Deciding upon the finest type of rifle scope depends on what type of shooting you plan to do.
First Focal Plane Scope Info
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This triggers the reticle to increase in size based upon the extent of zoom being used. The result 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 one hundred yards with no “zoom” is still the same tick at 100 yards by using 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who have an idea for their target “hold over” and also “lead” equations for their firearm
- Shooters who do not mind the reticle is enlarged and occupies more visual sight space than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification 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.
- Far away kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most shots take place within shorter ranges and distances
- Shooters who prefer a clearer optic picture with less area taken up by the bigger FFP reticle
Zoom for Optics
The quantity of magnification a scope supplies is figured out by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Glass Info
A single power rifle scope and optic comes with a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not adjust given that it is set from the factory.
Variable Power Lens Rifle Scope Info
Variable power rifle scopes use variable power levels. The power adjustment is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power and Ranges
Here are some recommended scope power levels and the ranges where they may be successfully used. High power glass will not be as efficient as lower magnification level rifle scope glass given that too much zoom can be a negative aspect depending on your shooting distance. The same idea relates to longer distances where the shooter needs to have sufficient power to see precisely where to best aim the rifle.
Lens Finishing for Scopes
All state-of-the-art rifle scope lenses are covered. Lens coating can be an essential element of a rifle’s setup when purchasing high end rifle optics and scope equipment.
About Lens Coatings – HD Versus ED
Some scope producers also use “HD” or high-definition lens coatings which use different methods, chemicals, polarizations, and components to draw out separate colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Info on Single Coating Versus Multi-Coating
Various scope lenses can even have various finishes applied to them. All lenses normally have at least some kind of treatment or finish applied to them before they are used in a rifle scope or optic. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally usable in many types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while decreasing glare and other less beneficial 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 manufacturers similarly make it a point to specify if their optic lenses are coated or “multi” coated. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Hydrophobic Finishing for Optics
Water on a lens doesn’t improve retaining a clear sight picture through an optic whatsoever. Lots of 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 exterior surfaces of the Steiner glass lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads roll off of the scope to keep a clear, water free sight picture.
Options for Mounting Optics on Long Guns
Mounting solutions for scopes can be found in a couple of options. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also normally come in quick release versions which use throw levers which enable rifle shooters to quickly mount and remove the scopes.
Hex Key Scope Rings
Basic, clamp-on style mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mount rails on the tops of rifles. These forms of scope mounts use two detached rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are designed for far away precision shooting. This type of scope mount is effective for rifle systems which need a long lasting, rock solid mount which will not change regardless of how much the scope is moved about or abuse the rifle takes. These are the type of mounts you should have for a devoted optics setup on a reach out and touch someone scouting or hard target interdiction rifle that will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on screws to keep the hex screws from wiggling out after they are installed securely in position. An example of these rings are the 30mm style made by the Vortex Optics brand. The set generally costs around $200 USD
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and attach it to a different rifle. Several scopes can also be switched out if they all use a compatible style mount. These types of mounts are handy for rifles which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used in between several rifles.
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle glass can spoil a day on the range and your expensive optic by inducing fogging and generating residue inside of the scope tube. Most optics protect against wetness from getting in the scope tube with a system of sealing O-rings which are water resistant. Generally, these scopes can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture prevention for basic use rifles, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still working if it is submerged in water and you can still retrieve the gun.
Gas Purged Rifle Scope Tubes
Another element of preventing the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the glass is less influenced by condition alterations 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 exist. These are good qualities of a good rifle scope to look for.
