Rifle Glass Facts
Rifle scopes allow you to exactly aim a rifle at different targets by lining up your eye with the target over a distance. They do this through magnification by utilizing a series of lenses within the scope. The scope’s positioning can be adjusted to take into account numerous environmental things like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the target. The majority of contemporary rifle scopes and optics have around eleven parts which are arranged internally and on the exterior of the optic. These optic pieces consist of the rifle scope’s body, lenses, adjustment turrets, focus rings, and other elements. Learn about the eleven parts of scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the best type of rifle scope is based around what type of shooting you plan to do.
About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are low
- Experienced shooters who have an idea for their target “hold over” and also “lead” ratios for their long gun
- Shooters who do not mind the reticle is bigger and takes up more visual sight space than a SFP reticle
Second Focal Plane Scope Info
Second focal plane optics (SFP) feature the reticle behind the zoom lens. 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 reticle measurement.
- Long distance forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots occur within shorter proximities and ranges
- Shooters who prefer a clearer optic sight picture without space taken up by the larger size FFP reticle
Rifle Scope Zoom
The amount of scope magnification you need on your glass depends upon the kind of shooting you plan to do. Practically every style of rifle scope offers some amount of magnification. The quantity of zoom a scope delivers is established by the dimension, density, and curves of the lens glass inside of the rifle optic. The magnification of the optic is the “power” of the glass. This signifies what the shooter is aiming at through the scope is amplified times the power factor of what can normally be seen by human eyes.
Fixed Power Lens Glass
A single power rifle scope and optic will have a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not fluctuate since it is a fixed power optic.
Variable Power Lens Rifle Glass
Variable power rifle scopes have adjustable power. It will list the magnification amount in a format like 2-10×32. These numbers imply the zoom of the scope can be changed in between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power adaptation is accomplished by operating the power ring component of the scope near the rear of the scope by the eye bell piece.
Power and Range
Here are some recommended scope powers and the distances where they may be efficiently used. High power optics will not be as effective as lower magnification glass because too much magnification can be a negative aspect depending on your shooting distance. The very same idea relates to longer distances where the shooter needs to have sufficient power to see exactly where to best aim the rifle.
Info on Lens Finishes
All modern rifle scope lenses are layered. Lens covering can be a significant aspect of a rifle when thinking about high end rifle optics and scope setups.
ED Versus HD Rifle Optics
Some scope manufacturers likewise use “HD” or high-definition lens finishings which use different techniques, chemicals, components, and polarizations to draw out various colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Glass Lens Single Covering Versus Multi-Coating
Different scope lenses can even have various coverings applied to them. All lenses usually have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally functional in numerous types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can safeguard the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope designer and the amount you spent paying for it. The scope’s maker and cost are indications of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are coated or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of products used in building the rifle scope.
Hydrophobic Glass Lens Coating
Water on a lens does not help with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic coating which is water repellent.
Options for Mounting Rifle Glass on Firearms
Mounting solutions for scopes are available in a couple of choices. There are the basic scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also normally are made in quick release versions which use throw levers which enable rifle operators to quickly mount and dismount the scope.
Hex Key Scope Ring Mounts
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount 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 created for long distance precision shooting. This type of scope install is fine for rifles which need a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly take off a scope and connect it to a different rifle. Numerous scopes can even be swapped out if they all use a similar style mount. These types of mounts are convenient for rifle platforms which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between multiple rifles.
About Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. Most scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Details on Rifle Scope Tube Gas Purging
Another part of avoiding the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the scope is less altered by condition changes and pressure distinctions from the outdoor environment which may possibly permit 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.
