Rifle Glass Info
Rifle scopes permit you to precisely align a rifle at different targets by aligning your eye with the target at range. They do this through magnifying the target using a set of lenses inside the scope. The scope’s positioning can be dialed in to account for many ecological elements like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based on the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the intended point of impact. Many contemporary rifle scopes and optics have about 11 parts which are found within and outside of the scope body. These parts include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other parts. Learn about the eleven parts of glass.
About Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The sort of focal plane a scope has establishes where the reticle or crosshair is located relative to the optic’s magnifying adjustments. It actually means the reticle is situated behind or in front of the magnification lens of the scope. Considering the best kind of rifle scope is dependent on what sort of shooting or hunting you plan on undertaking.
About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the level of magnification being used. The benefit is that the reticle measurements are the same at the enhanced distance as they are at the non amplified range. For example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the corresponding tick at one hundred yards using 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are small
- Experienced shooters who understand their target “hold over” and also “lead” relationships for their firearm
- Shooters who don’t mind the reticle is bigger and requires more visual sight area than a SFP reticle
Second Focal Plane Scope Details
Second focal plane scopes (SFP) come with the reticle to the rear of the magnifying lens. This causes the reticle to stay at the same dimensions in connection with the amount of zoom being used. The end result is that the reticle dimensions adjust based upon the magnification used to shoot over lengthier distances considering that the reticle measurements represent different increments which differ with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These varieties of scopes are useful for:
- Long distance types of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots occur within much shorter spaces and ranges
- Shooters who like a clearer optic sight picture without space used up by the larger sized FFP reticle
Magnification for Rifle Glass
The level of scope zoom you need on your scope depends on the sort of shooting you desire to do. Pretty much every kind of rifle scope delivers some level of magnification. The amount of magnification a scope provides is established by the diameter, density, and curvatures of the lenses within the rifle scope. The magnification of the optic is the “power” of the glass. This means what the shooter is aiming at through the scope is amplified times the power aspect of what can generally be seen by human eyes.
Info on Fixed Power Lens Rifle Optics
A single power rifle scope or optic comes with a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not adjust given that it is a fixed power optic.
About Variable Power Lens Rifle Optics
Variable power rifle scopes can be changed between magnification power levels. It will list the zoom degree in a format like 2-10×32. These numbers suggest the zoom of the scope could be adjusted between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power modification is accomplished by applying the power ring component of the scope near the back of the scope by the eye bell.
The Power Level and Range of Rifle Glass
Here are some advised scope powers and the ranges where they can be efficiently used. Highly magnified scopes will not be as useful as lower magnification level glass given that too much magnification can be a negative aspect depending on your shooting distance. The exact same idea relates to extended distances where the shooter needs increased power to see precisely where to properly aim the rifle at the target.
Details on Optic Lens Coatings
All cutting-edge rifle glass lenses are layered. Lens coating can be a crucial element of a shooting system when buying high end rifle optics and scope setups.
HD Versus ED Rifle Optic Lens Coatings
Some scope producers also use “HD” or high-definition lens finishes which use various processes, elements, polarizations, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Rifle Scope Lens Single Finishing Versus Multi-Coating
Various optic lenses can also have different finishings used to them. All lenses typically have at least some type of treatment or covering used to them before they are used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing 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 makers also make it a point to specify if their optic lenses are covered or “multi” coated. Being “much better” depends on the producer’s lens treatment technology and the quality of materials used in building the rifle scope.
Hydrophobic Lens Finish
Water on an optic’s lens does not assist with keeping a clear sight picture through a scope in any way. Many top of the line or high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the surface area of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The outcome is that the water beads roll off of the scope to keep a clear, water free sight picture.
Glass Mounting Options
Mounting options for scopes come in a few choices. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also usually come in quick release versions which use toss levers which permit rifle operators to rapidly install and dismount the glass.
Rifle Optic Mounting Solutions with Hex Key Rings
Standard, clamp type mounting optic rings use hex head screws to install to the flattop style Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use a pair of individual rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are designed for far away precision shooting. This kind of scope mount is good for rifles which need a durable, unfailing mount which will not move despite how much the scope is moved about or abuse the rifle takes. These are the type of mounts you should get for a faithful optics setup on a reach out and touch someone hunting or interdiction firearm that will almost never need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount screws to prevent the hex screws from backing out after they are mounted safely in position. An example of these rings are the 30mm type made by the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible design mount. These types of mounts come in handy for rifle platforms which are transported a lot, to remove the optic from the rifle for protection, or for optics which are used in between several rifles or are situationally focused.
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can spoil a day of shooting and your highly-priced optic by triggering fogging and developing residue within the scope’s tube. A lot of scopes prevent moisture from going into the optical tube with a system of sealing O-rings which are waterproof. Usually, these water-resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture avoidance for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still performing if it falls overboard and you can still salvage the rifle.
Scope Gas Purging
Another element of avoiding the accumulation of moisture within the rifle optic 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 altered by temperature level alterations and pressure distinctions from the outside environment which may potentially enable water vapor to leak 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.
