Rifle Optic Details
Rifle scopes permit you to precisely align a rifle at various targets by aligning your eye with the target over a range. They accomplish this through magnification using a series of lenses inside the scope. The scope’s alignment can be adjusted to account for different ecological elements like wind and elevation to account for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the intended target. Many contemporary rifle optics have about eleven parts which are found within and outside of the optic. These scope parts include the rifle scope’s body, lenses, elevation turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of rifle scopes.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the best type of rifle optic depends on what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are minimal
- Experienced shooters who understand their target “hold over” plus “lead” correlations for their firearm
- Shooters who do not mind the reticle is bigger and takes up more visual sight area than a SFP reticle
Second Focal Plane Optic Info
Second focal plane optics (SFP) include the reticle to the rear of the magnifying lens. This triggers the reticle to remain at the very same dimensions relative to the level of magnification being used. The effect is that the reticle dimensions adapt based on the magnification chosen to shoot over longer ranges due to the fact that the reticle measurements represent various increments which can vary with the magnification level. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick. These kinds of optics are handy for:
- Long distance styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots occur within shorter ranges and distances
- Shooters who want a clearer optic sight picture without area used up by the enlarged FFP reticle
Magnification for Scopes
The quantity of zoom a scope provides is identified 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.
Info on Fixed Power Lens Rifle Glass
A single power rifle scope or optic comes with a zoom 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 type of optic can not change because it is a fixed power optic.
Variable Power Lens Glass
Variable power rifle scopes can be changed between magnification levels. These types of scopes will list the zoom amount in a configuration such as 2-10×32. These numbers indicate the zoom of the scope can be changed between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power modification is accomplished by working with the power ring component of the scope near the back of the scope by the eye bell piece.
Power and Range Correlations
Here are some advised scope power levels and the ranges where they can be efficiently used. Always remember that higher power optics will not be as practical as lower magnification level scope and optics since too much magnification can be a bad thing. The same idea goes for extended distances where the shooter needs enough power to see precisely where to best aim the rifle.
Info on Rifle Glass Lens Coverings
All contemporary rifle scope lenses are layered. There are different types and qualities of finishes. Lens covering can be a crucial aspect of a rifle’s setup when contemplating high end rifle optics and scope equipment. The glass lenses are among the most vital parts of the scope given that they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses offers protection to the lens exterior and even improves anti glare from excess light and color presence.
About Rifle Glass Lens Coatings – HD Versus ED
Some rifle glass makers also use “HD” or high-definition lense finishings that employ different processes, aspects, polarizations, and chemical applications to draw out different color ranges and viewable target visibility through lenses. This high-def finish is commonly used with more costly, high density lens glass which brings down light’s chance to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration is often visible over items with defined outlines as light hits the object from specific angles.
Single Coating Versus Multi-Coating
Various optic lenses can also have various finishings applied to them. All lenses usually have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic. Since 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 it will be optimally functional in lots of types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing 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 on the scope maker and how much you spent paying for it. The scope’s maker and cost are signs of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are coated or “multi” coated. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in developing the rifle scope.
Anti-water Finish for Glass
Water on an optical lens does not support maintaining a clear sight picture through an optic at all. Many top of the line or premium optic manufacturers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It treats the surface of the Steiner optic lens so the water particles can not bind to it or create surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Alternatives for Installing Glass on Firearms
Mounting options for scopes come in a few choices. 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 usually can be found in quick release versions which use toss levers which permit rifle operators to rapidly mount and remove the scopes.
Hex Key Glass Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long range accuracy shooting. This type of scope install is fine for rifles which require a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Rings
These kinds of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle. If they all use a comparable design mount, multiple scopes can often be swapped out. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while keeping the original sighting settings. These types of mounts come in beneficial for rifles which are moved around a lot, to remove the scope glass from the rifle for protection, or for optics which are used between several rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by triggering fogging and producing residue inside of the scope tube. Most scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Rifle Glass Gas Purging
Another element of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the optic is less impacted by climate changes and pressure distinctions from the outdoor environment which might potentially permit water vapor to seep 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.
