Rifle Glass Info
Rifle scopes allow you to specifically align a rifle at various targets by lining up your eye with the target over a distance. They do this through zoom by employing a series of lenses inside the scope. The scope’s alignment can be dialed in for consideration of many environmental elements 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 upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of contemporary rifle scopes have around eleven parts which are found within and outside of the scope body. These scope parts include the rifle scope’s body, lenses, windage dials, focus rings, and other parts. Learn about the eleven parts of rifle scopes.
About Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the finest type of rifle scope is based around what type of shooting you plan on doing.
First Focal Plane Optics
First focal plane optics (FFP) feature the reticle before the magnification lens. This induces the reticle to increase in size based on the amount of zoom being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who have an idea for their aim point “hold over” and “lead” equations for their firearm
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. This causes the reticle to stay at the same overall size in connection with the quantity of zoom being used. The outcome is that the reticle measurements adapt based upon the magnification employed to shoot over greater ranges considering that the markings represent various increments which 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 particular sorts of optics are useful for:
- Far away kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots occur within much shorter spaces and ranges
- Shooters who would like a clearer optic picture with less area used up by the larger size FFP reticle
Magnification for Optics
The measure of scope zoom you need on your optic is based on the form of shooting you would like to do. Practically every style of rifle scope delivers some amount of zoom. The quantity of zoom a scope supplies is determined by the dimension, density, and curves of the lens glass inside of the rifle scope. The magnifying level of the scope is the “power” of the scope. This indicates what the shooter is aiming at through the scope is amplified times the power element of what can usually be seen by human eyes.
Single Power Lens Rifle Scopes
A single power rifle scope or optic uses a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not adjust since it is fixed.
Adjustable Power Lens Glass
Variable power rifle scopes can be adjusted between magnification levels. These types of scopes will list the magnification level in a format such as 2-10×32. These numbers mean the zoom of the scope could be set in between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power modification is achieved utilizing the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range of Rifle Scopes
Here are some suggested scope powers and the ranges where they can be efficiently used. Keep in mind that high magnification scopes and optics will not be as effective as lower powered scopes since too much zoom can be a bad thing. The exact same concept relates to extended distances where the shooter needs to have sufficient power to see exactly where to properly aim the rifle.
About Scope Lens Coatings
All modern rifle optic and scope lenses are covered in special coatings. There are different types and qualities of coverings. When looking at high end rifle scope systems, Lens finishing can be a crucial aspect of defining the rifle’s capability. The glass lenses are among the most vital components of the optic since they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses safeguards the lens surface area and also assists with anti glare from excess light and color recognition.
Details on Lens Coatings – HD Versus ED
Some scope brands likewise use “HD” or high-definition lens finishes which use various procedures, elements, chemicals, and polarizations to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
About Single Finish Versus Multi-Coating
Different scope lenses can also have various finishes applied to them. All lenses usually have at least some kind of treatment or finishing applied to them before being used in a rifle scope or optic assembly. Since the lens isn’t just 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 efficiently functional in numerous kinds of environments, degrees of sunshine (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 makers also make it a point to define if their optic lenses are layered or “multi” coated. This suggests the lens has had multiple treatments applied to the surfaces. If a lens gets several treatments, it can prove that a company is taking several steps to combat different natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This additionally does not necessarily suggest the multi-coated lens is better than a single covered lens. Being “much better” hinges on the manufacturer’s lens treatment technology and the quality of products used in building the rifle optic.
Anti-water Rifle Optic Lens Finishing
Water on a scope’s lens doesn’t support maintaining a clear sight picture through an optic in any way. Numerous top of the line and high-end optic producers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the exterior of the Steiner scope lens so the water particles can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Optic Installation Alternatives
Mounting options for scopes come in a couple of 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 kinds of mounts also generally are made in quick release variations which use manual levers which allow rifle operators to quickly install and remove the glass.
Hex Key Glass Rings
Standard, clamp design mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a pair of independent rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are developed for long distance precision shooting. This kind of scope mount is ideal for rifles which require a durable, hard use mount which will not move no matter how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should get for a dedicated optics setup on a far away hunting or competitors long gun that will seldom need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to keep the hex screw threads from wiggling out after they are mounted securely in position. An example of these rings are the 30mm type made by Vortex Optics. The set generally costs around $200 USD
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, a number of scopes can also be swapped out. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining the original sighting settings. These types of mounts come in handy for shooting platforms which are moved a lot, to remove the glass from the rifle for protection, or for optics which are chosen for use between multiple rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Info on Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle glass can wreck a day of shooting and your highly-priced optic by triggering fogging and developing residue inside of the scope tube. Most optics prevent humidity from getting in the optical tube with a system of sealing O-rings which are waterproof. Usually, these optics can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture avoidance for standard use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on a boat and are concerned about the scope still working if it goes over the side and you can still retrieve the rifle.
Rifle Glass Gas Purging
Another element of avoiding the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the glass is less influenced by temperature level alterations and pressure variations from the outside environment which may possibly allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
