Rifle Optic Information
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target over a range. They do this through magnifying the target by employing a set of lenses within the scope. The scope’s alignment can be dialed in for the consideration of separate natural considerations like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended target. Most modern-day rifle scopes and optics have around 11 parts which are located inside and on the exterior of the scope. These parts include the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other elements. See all eleven parts of scopes.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the best type of rifle glass is based around what type of shooting you plan on doing.
Info on First Focal Plane Glass
First focal plane optics (FFP) include the reticle in front of the magnifying lens. This induces the reticle to increase in size based upon the level of magnification being used. The outcome 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 100 yards with no “zoom” is still the same tick at one hundred yards by using 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where calculations are small
- Experienced shooters who have an idea for their target “hold over” as well as “lead” ratios for their firearms
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle to the rear of the magnification lens. This triggers the reticle to stay at the same dimensions in relation to the quantity of zoom being used. The effect is that the reticle measurements adjust based on the magnification employed to shoot over greater distances because the markings represent various increments which differ with the zoom level. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These varieties of optics are handy for:
- Long distance forms of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots happen within much shorter ranges and distances
- Shooters who want a clearer optic picture without area used up by the larger sized FFP reticle
Zoom for Scopes
The amount of scope magnification you need on your glass depends upon the form of shooting you desire to do. Virtually every type of rifle optic gives some amount of zoom. The volume of magnification a scope delivers is established by the dimension, density, and curvatures of the lenses inside of the rifle optic. The zoom of the scope is the “power” of the scope. This implies what the shooter is checking out through the scope is amplified times the power aspect of what can usually be seen by human eyes.
Fixed Power Lens Optics
A single power rifle scope or optic uses a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate considering that it is a fixed power optic.
Adjustable Power Lens Optic Details
Variable power rifle scopes have adjustable power. It will list the magnification degree in a format such as 2-10×32. These numbers imply the magnification of the scope could be adjusted between 2x and 10x power. This always involves the powers in-between 2 and 10. The power manipulation is achieved by employing the power ring component of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some recommended scope powers and the distances where they could be efficiently used. Bear in mind that high magnification optics will not be as effective as lower magnification level glass due to the fact that too much zoom can be a detractor. The same concept relates to extended distances where the shooter needs sufficient power to see exactly where to properly aim the rifle.
Info on Rifle Scope Lens Covering
All modern rifle scope lenses are covered in special coatings. There are various types and qualities of glass lens finishings. When shopping for high end rifle optical systems, Lens coating can be a critical component of a rifle. The lenses are one of the most crucial components of the optic as they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses shields the lens exterior and also assists with anti glare from refracted natural light and color visibility.
ED Versus HD Rifle Optics
Some glass producers also use “HD” or high-definition lens coatings that make the most of various processes, chemicals, polarizations, and aspects to draw out a wide range of colors and viewable target visibility through lenses. This high-definition coating is commonly used with greater density glass which lowers light’s capability to refract by means of the lens glass. Some scope suppliers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration may be noticeable over objects with hard edges and shapes as light hits the item from various angles.
Rifle Glass Lens Single Covering Versus Multi-Coating
Different optic lenses can also have various coatings applied to them. All lenses typically have at least some type of treatment or covering used to them before being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while lowering 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 maker and how much you paid for it.
Some scope manufacturers likewise make it a point to define if their optic lenses are coated or “multi” coated. This means the lens has had several treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can indicate that a producer is taking numerous actions to combat various natural factors like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This also doesn’t always mean the multi-coated lens will perform better than a single layered lens. Being “better” is dependent on the maker’s lens treatment solutions and the quality of materials used in developing the rifle glass.
About Anti-water Finish
Water on a scope lens does not assist with preserving a clear sight picture through an optic in any way. Numerous top of the line and high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the exterior surfaces of the Steiner optic lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Alternatives for Mounting Rifle Scopes on Firearms
Mounting approaches for scopes can be found in a couple of options. There are the basic scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also typically can be found in quick release versions which use manual levers which allow rifle operators to quickly mount and dismount the optics.
Hex Key Rifle Scope Ring Mounting Solutions
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 a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope mount is perfect for rifles which need a resilient, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be switched out if they all use a similar design mount. These types of mounts come in handy for rifles which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between numerous rifles or are situationally focused.
Info Around Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. Most scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Optic Tubes
Another element of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less impacted by condition changes and pressure variations from the outside environment which may potentially permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
