Optic Info
Rifle scopes enable you to specifically align a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification by using a series of lenses inside the scope. The scope’s alignment can be dialed in to take into account different ecological elements like wind and elevation to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will land based upon the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes and optics have about eleven parts which are arranged inside and externally on the optic. These optic pieces consist of the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other parts. Learn about the eleven parts of glass.
About Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane a scope has identifies where the reticle or crosshair lies in regard to the optic’s magnification. It simply means the reticle is situated behind or ahead of the magnifying lens of the scope. Picking out the most desired kind of rifle optic is dependent on what kind of shooting you plan on doing.
First Focal Plane Scope Details
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where calculations are minor
- Experienced shooters who understand their aim point “hold over” and also “lead” correlations for their rifles
- Shooters who do not mind the reticle is enlarged and occupies more visual sight area than a SFP reticle
Second Focal Plane Optic Details
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. This triggers the reticle to stay at the same overall size relative to the quantity of magnification being used. The outcome is that the reticle dimensions adapt based on the magnification chosen to shoot over lengthier ranges since the reticle markings present distinct increments which fluctuate with the zoom. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick. These particular varieties of glass are beneficial for:
- Far away forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots occur within shorter spaces and ranges
- Shooters who want a clearer optic picture without room used up by the larger size FFP reticle
Zoom for Rifle Glass
The measure of scope magnification you need on your glass depends on the form of shooting you plan to do. Nearly every type of rifle optic provides some degree of magnification. The level of magnification a scope provides is identified by the diameter, density, and curvatures of the lens glass within the rifle scope. The zoom of the optic is the “power” of the glass. This suggests what the shooter is looking at through the scope is amplified times the power aspect of what can typically be seen by human eyes.
Fixed Power Lens Optics
A single power rifle scope will have a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not change considering that it is fixed.
About Adjustable Power Lens Scopes
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification degree in a configuration like 2-10×32. These numbers suggest the zoom of the scope could be set between 2x and 10x power. This additionally includes the power levels in-between 2 and 10. The power modification is achieved by employing the power ring part of the scope near the back of the scope by the eye bell.
Rifle Glass Power and Ranges
Here are some recommended scope power levels and the ranges where they could be efficiently used. Always remember that higher magnification scopes will not be as efficient as lower powered scopes because increased zoom can be a bad thing. The same concept relates to longer ranges where the shooter needs enough power to see where to best aim the rifle at the target.
Rifle Optic Lens Coating
All modern rifle optic lenses are covered. Lens finishing is an important aspect of a shooting system when purchasing high end rifle optics and scope setups.
HD Versus ED Lenses
Some glass makers even use “HD” or high-def lense coatings that make the most of different procedures, elements, rare earth compounds, and polarizations to draw out different colors and viewable target definition through the lens. This HD finish is often used with increased density lens glass which brings down light’s potential to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration can be visible around items with well defined shapes as light hits the object from specific angles.
Details on Single Finish Versus Multi-Coating
Various optic lenses can also have different finishings applied to them. All lenses typically have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic. This is due to the fact that the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It needs to have a finishing placed on it so that the lens will be optimally usable in lots of types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while decreasing glare and other less useful 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 also make it a point to specify if their optic lenses are coated or “multi” covered. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of products used in developing the rifle scope.
Rifle Scope Lens Hydrophobic Finishing
Water on an optical lens does not help with preserving a clear sight picture through a scope whatsoever. Many top of the line or premium optic manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior surfaces of the Steiner scope lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to keep a clear, water free sight picture.
Scope Mounting Options
Installing options for scopes are available in a couple of choices. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also usually come in quick release versions which use manual levers which enable rifle shooters to rapidly install and dismount the scopes.
Hex Key Glass Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount 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 is developed for long range precision shooting. This type of scope install is perfect for rifles which need a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a similar style mount. These types of mounts come in handy for rifle platforms which are transported a lot, to swap out the optic from the rifle for protection, or for optics which are used in between multiple rifles or are situationally focused.
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can wreck a day of shooting and your pricey optic by inducing fogging and developing residue inside of the scope’s tube. Many optics protect against humidity from getting in the optical tube with a series of sealing O-rings which are waterproof. Typically, these water-resistant scopes can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of wetness prevention for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are worried about the scope still performing if it goes overboard and you can still retrieve the firearm.
Info Around Rifle Glass Tube Gas Purging
Another part of preventing the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the glass is less impacted by temp shifts and pressure differences from the external environment which might potentially permit 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 seek out.
