Rifle Glass Facts
Rifle scopes enable you to exactly aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnifying the target by making use of a series of lenses within the scope. The scope’s alignment can be dialed in for consideration of many environmental factors like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle scopes and optics have about 11 parts which are arranged internally and outside of the scope body. These scope parts include the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane an optic has decides where the reticle or crosshair is located in regard to the optic’s zoom. It actually indicates the reticle is located behind or ahead of the magnification lens of the scope. Selecting the very best kind of rifle glass is based upon what kind of shooting you anticipate doing.
First Focal Plane Glass Info
First focal plane glass (FFP) come with the reticle before the magnification lens. This induces the reticle to increase in size based upon the amount of magnification being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the same tick at 100 yards with 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are minimal
- Experienced shooters who recognize their aim point “hold over” as well as “lead” ratios for their firearm
- Shooters who don’t mind the reticle is bigger and occupies more visual sight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane glass (SFP) feature the reticle to the rear of the magnifying lens. This triggers the reticle to stay at the same overall size in relation to the level of magnification being used. The effect is that the reticle dimensions adapt based on the magnification chosen to shoot over lengthier ranges considering the reticle measurements present distinct increments which vary with the zoom level. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These particular sorts of glass work for:
- Far away styles of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who would like a clearer optic sight picture with less space used up by the larger sized FFP reticle
About Optic Magnification
The amount of scope magnification you require depends on the style of shooting you would like to do. Almost every kind of rifle glass offers some degree of magnification. The volume of zoom a scope provides is determined by the dimension, thickness, and curves of the lens glass inside of the rifle optic. The magnification of the scope is the “power” of the scope. This suggests what the shooter is aiming at through the scope is amplified times the power factor of what can typically be seen by human eyes.
Single Power Lens Optics
A single power rifle optic comes with a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not fluctuate since it is fixed.
Adjustable Power Lens Scopes
Variable power rifle scopes have adjustable power. It will list the zoom level in a format such as 2-10×32. These numbers imply the magnification of the scope could be set in between 2x and 10x power. This additionally includes the powers in-between 2 and 10. The power modification is accomplished utilizing the power ring component of the scope near the back of the scope by the eye bell piece.
Power Levels and Range Correlations
Here are some advised scope power levels and the ranges where they can be efficiently used. Always remember that high magnification scopes will not be as effective as lower powered scopes since too much zoom can be a negative thing in certain situations. The same concept relates to longer ranges where the shooter needs sufficient power to see precisely where to properly aim the rifle.
Info on Rifle Optic Lens Coating
All modern rifle optic and scope lenses are covered. Lens finish can be a vital aspect of a shooting platform when looking into high end rifle optics and scope equipment.
Details on Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens finishes which use different methods, polarizations, chemicals, and aspects to draw out separate colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Various scope lenses can also have various coatings applied to them. All lenses normally have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic. This is because the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that it will be efficiently functional in lots of kinds of environments, degrees of sunshine (full VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope designer and just how much you paid for it. Both the make and cost are signs of the lens quality.
Some scope manufacturers likewise make it a point to define if their optic lenses are covered or “multi” coated. This suggests the lens has had multiple treatments applied to them. If a lens receives several treatments, it can prove that a company is taking multiple actions to combat different environmental factors like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This additionally doesn’t necessarily indicate the multi-coated lens will perform much better than a single layered lens. Being “better” is dependent on the producer’s lens treatment technology and the quality of glass used in creating the rifle glass.
Anti-water Lens Finishes
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Many top of the line and military grade scope companies will coat their lenses with a hydrophobic or hydrophilic finish which is water repellent.
Options for Mounting Glass on Firearms
Installing approaches for scopes are available in a couple of options. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually come in quick release versions which use toss levers which enable rifle shooters to rapidly mount and dismount the scopes.
Hex Key Rifle Scope Rings
Standard, clamp style mounting optic rings use hex head screws to position to the flattop design Picatinny scope mount rails on the tops of rifles. These types of scope mounts use two independent rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are made for far away accuracy shooting. This form of scope mount is good for rifle systems which need to have a long lasting, rock solid mount which will not change regardless of how much the scope is moved or abuse the rifle takes. These are the style of mounts you really want to have for a specialized scope system on a far away scouting or sniper competition long gun that will pretty much never need to be modified or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the screws to keep the hex screw threads from backing out after they are installed securely in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can even be switched out if they all use a similar style mount. These types of mounts are handy for long guns which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between several rifles or are situationally focused.
Scope Tube Sealing and Gas Purging
Moisture inside your rifle glass can mess up a day on the range and your highly-priced optic by resulting in fogging and making residue inside of the scope tube. Many scopes protect against moisture from entering the scope tube with a series of sealing O-rings which are water resistant. Typically, these water resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient humidity avoidance for conventional use rifles, unless you plan on taking your rifle on a boat and are concerned about the optic still working if it goes over the side and you can still recover the rifle.
Rifle Glass Gas Purging
Another element of avoiding the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the scope is less altered by condition alterations and pressure distinctions from the outside environment which might possibly allow water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
