Scope Information
Rifle scopes permit you to exactly aim a rifle at various targets by aligning your eye with the target at range. They do this through magnification using a series of lenses within the scope. The scope’s alignment can be adapted for consideration of many ecological things like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will land based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the target. Most contemporary rifle scopes have about 11 parts which are found inside and externally on the scope body. These parts include the rifle scope’s body, lenses, elevation turrets, focus rings, and other elements. See all eleven parts of an optic.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the finest type of rifle scope depends on what type of shooting you plan to do.
First Focal Plane Scopes
First focal plane glass (FFP) come with the reticle ahead of the zoom lens. This induces the reticle to increase in size based upon the level of zoom being used. The result is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. For instance, one tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at 100 yards with 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are very little
- Experienced shooters who recognize their target “hold over” and “lead” correlations for their long guns
- Shooters who do not mind the reticle is enlarged and takes up more visual sight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane glass (SFP) feature the reticle behind the magnifying lens. This triggers the reticle to remain at the same scale relative to the quantity of zoom being used. The outcome is that the reticle dimensions adjust based upon the magnification used to shoot over lengthier ranges because the reticle measurements represent distinct increments which differ with the magnification. 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. These particular kinds of glass work for:
- Long distance types of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots take place within shorter ranges and spaces
- Shooters who select a clearer optic picture with less room used up by the bigger FFP reticle
Magnification for Scopes
The quantity of scope zoom you need on your scope is based on the style of shooting you want to do. Almost every kind of rifle scope provides some level of zoom. The volume of zoom a scope gives is determined by the diameter, density, and curves of the lens glass within the rifle optic. The magnification level of the scope is the “power” of the scope. This denotes what the shooter is observing through the scope is amplified times the power aspect of what can typically be seen by human eyes.
Fixed Power Lens Rifle Optics
A single power rifle optic and scope comes with a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not fluctuate because it is set from the factory.
Adjustable Power Lens Rifle Glass Info
Variable power rifle scopes can be changed between magnification increments. It will list the zoom amount in a format such as 2-10×32. These numbers indicate the zoom of the scope can be set between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power adjustment is accomplished using the power ring component of the scope near the rear of the scope by the eye bell piece.
Power and Range
Here are some suggested scope power levels and the ranges where they can be efficiently used. Keep in mind that higher magnification optics and scopes will not be as efficient as lower magnification level glass since too much magnification can be a bad thing. The same concept goes for extended distances where the shooter needs increased power to see where to properly aim the rifle at the target.
Info on Lens Finish
All contemporary rifle optic lenses are layered. Lens finish can be a crucial element of a shooting system when thinking about high end rifle optics and scope systems.
Info on Lens Coatings – HD Versus ED
Some scope makers additionally use “HD” or high-def lense finishes that apply various processes, polarizations, elements, and chemicals to extract a wide range of colors and viewable definition through lenses. This high-def coating is normally used with greater density lens glass which brings down light’s capability to refract by means of the lens glass. Some scope producers use “HD” to refer to “ED” suggesting 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 visible around items with hard outlines as light hits the object from certain angles.
Rifle Scope Lens Single Coating Versus Multi-Coating
Different scope lenses can also have various coverings applied to them. All lenses generally have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It needs to have a finishing put on it so that the lens will be optimally functional in lots of kinds of environments, degrees of light (full VS shaded), and other shooting conditions.
This lens treatment can safeguard 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 maker and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” coated. This suggests the lens has had numerous treatments applied to the surfaces of the glass. If a lens gets several treatments, it can show that a maker is taking several steps to combat different environmental elements like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also doesn’t necessarily mean the multi-coated lens will perform much better than a single covered lens. Being “much better” hinges on the manufacturer’s lens treatment techniques and the quality of materials used in creating the rifle optic.
Anti-water Rifle Glass Lens Coating
Water on a lens does not help with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade scope companies will coat their lenses with a hydrophobic or hydrophilic finishing.
Alternatives for Installing Rifle Optics on Firearms
Installing approaches for scopes come in a few choices. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also generally come in quick release variations which use manual levers which allow rifle operators to rapidly mount and dismount the glass.
Rifle Glass Mounts with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range precision shooting. This type of scope install is fine for rifles which need a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle. A wide range of scopes can also be switched out if they all use a complementary designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining the original sighting settings. These types of mounts are useful and convenient for shooting platforms which are moved around a lot, to take off the scope from the rifle for protection, or for sight systems which are chosen for use in between a number of rifles. An example of this mount style is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Info on Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day of shooting and your costly optic by bringing about fogging and producing residue inside of the scope tube. A lot of scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Scope Tubes
Another part of avoiding the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the optic is less altered by temperature level shifts and pressure differences from the outdoor environment which may potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
