What You Need to Know About Rifle Glass
Rifle scopes enable you to exactly align a rifle at different targets by lining up your eye with the target over a distance. They do this through magnifying the target by utilizing a series of lenses inside the scope. The scope’s alignment can be adapted for consideration of varied natural considerations like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle optics have around eleven parts which are located within and on the exterior of the scope body. These optic pieces consist of the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other elements. See all eleven parts of scopes.
About Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the best type of rifle optic depends on what type of shooting you plan on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This induces the reticle to increase in size based on the amount of magnification being used. The outcome is that the reticle measurements are the same at the amplified distance as they are at the non magnified distance. For instance, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the very same tick at 100 yards with 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are minimal
- Experienced shooters who know their target “hold over” and also “lead” ratios for their weapon
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight space than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane glass (SFP) include the reticle to the rear of the magnifying lens. This induces the reticle to stay at the exact same overall size in relation to the level of magnification being used. The effect is that the reticle dimensions shift based upon the magnification employed to shoot over longer distances due to the fact that the markings represent distinct increments which can vary with the zoom. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These types of optics work for:
- Far away forms of shooting where shooters have more time to make ballistic computations
- Shooting where most shots occur within much shorter ranges and proximities
- Shooters who want a clearer optic picture without space taken up by the larger size FFP reticle
Zoom for Glass
The amount of scope zoom you need depends upon the kind of shooting you intend to do. Nearly every style of rifle optic supplies some degree of zoom. The amount of magnification a scope offers is established by the dimension, density, and curvatures of the lens glass within the rifle scope. The zoom of the scope is the “power” of the glass. This indicates what the shooter is observing through the scope is magnified times the power element of what can generally be seen by human eyes.
Fixed Single Power Lens Rifle Optics
A single power rifle optic comes with a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not adjust since it is a fixed power optic.
Variable Power Lens Optics
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification level in a configuration like 2-10×32. These numbers imply the magnification of the scope can be changed between 2x and 10x power. This also utilizes the powers in-between 2 and 10. The power adaptation is achieved by making use of the power ring component of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Optics
Here are some suggested scope powers and the distances where they may be efficiently used. Always remember that high magnification optics and scopes will not be as practical as lower magnification level scopes due to the fact that excessive magnification can be a negative thing in certain situations. The exact same concept relates to extended distances where the shooter needs increased power to see where to best aim the rifle.
Lens Coating for Rifle Glass
All modern rifle optic and scope lenses are layered. There are various types and qualities of lens finishes. Lens finish can be an essential aspect of a rifle’s setup when thinking about high-end rifle optics and scope systems. The glass lenses are among the most significant pieces of the optic considering that they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses offers protection to the lens exterior and also improves anti glare from excess sunlight and color discernibility.
About Rifle Optic Lens Coatings – HD Versus ED
Some rifle scope producers additionally use “HD” or high-definition lense coverings which use various processes, polarizations, rare earth compounds, and elements to draw out different colors and viewable definition through lenses. This HD coating is frequently used with more costly, high density glass which lowers light’s ability to refract by means of the lens glass. Some scope producers use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how certain colors are represented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around items with well defined shapes as light hits the object from specific angles.
Single Finishing Versus Multi-Coating
Various optic lenses can likewise have various coatings applied to them. All lenses typically have at least some type of treatment or coating used to them prior to being 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 coated lens depends on the scope maker and how much you paid for it.
Some scope makers likewise make it a point to define if their optic lenses are layered or “multi” coated. This suggests the lens has had several treatments applied to the surfaces of the glass. If a lens receives several treatments, it can show that a producer is taking numerous steps to fight various natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This also does not necessarily indicate the multi-coated lens is better than a single layered lens. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle optic.
Hydrophobic Finish for Rifle Scopes
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Lots of top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic finish.
Choices for Mounting Scopes on Firearms
Mounting solutions for scopes come in a few choices. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also generally are made in quick release variations which use throw levers which allow rifle shooters to quickly install and remove the scopes.
Hex Key Rifle Optic Ring Mounts
Basic, clamp design mounting scope rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use a pair of independent rings to support the optic, and are normally made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope mount is ideal for rifles which require a durable, hard use mount which will not shift despite just how much the scope is moved or abuse the rifle takes. These are the type of mounts you really want to have for a faithful optics setup on a reach out and touch someone scouting or competition rifle that will hardly ever need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the screws to protect against the hex screws from backing out after they are mounted securely in place. An example of these rings are the 30mm type from Vortex Optics. The set usually costs around $200 USD
Rifle Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, multiple scopes can often be swapped out on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining precision. These types of mounts come in convenient for rifles which are moved a lot, to remove the glass from the rifle for protection, or for aiming systems which are employed in between multiple rifles. An example of this mount type is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can wreck a day of shooting and your expensive optic by causing fogging and developing residue inside of the scope’s tube. Most optics prevent humidity from getting in the scope tube with a system of sealing O-rings which are waterproof. Usually, these optics can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of wetness 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 is submerged in water and you can still salvage the gun.
Rifle Glass Gas Purging
Another part of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the optic is less influenced by condition alterations and pressure variations from the outside environment which might possibly permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
