What You Need to Know About Rifle Glass
Rifle scopes permit you to exactly align a rifle at various targets by aligning your eye with the target at range. They do this through magnifying the target using a series of lenses inside the scope. The scope’s alignment can be dialed in for the consideration of varied natural things like wind speed and elevation to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many contemporary rifle optics have around 11 parts which are located inside and on the exterior of the scope. These scope parts consist of the rifle scope’s body, lenses, elevation dials, objective focus rings, and other parts. Learn about the eleven parts of rifle glass.
About Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the perfect type of rifle glass depends on what type of shooting you plan to do.
First Focal Plane Optic Details
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon 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 magnified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at 100 yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are low
- Experienced shooters who have an idea for their target “hold over” and “lead” correlations for their weapon
- Shooters who don’t mind the reticle is enlarged and requires more visual sight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle behind the zoom lens. 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.
- Long distance kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots take place within much shorter ranges and distances
- Shooters who like a clearer optic picture without area used up by the enlarged FFP reticle
Ins and Outs of Rifle Scope Zoom
The level of scope zoom you require depends on the sort of shooting you would like to do. Virtually every kind of rifle scope supplies some degree of magnification. The amount of magnification a scope provides is identified by the size, density, and curvatures of the lens glass inside of the rifle optic. The magnification of the optic is the “power” of the glass. This implies what the shooter is aiming at through the scope is amplified times the power element of what can typically be seen by human eyes.
Fixed Single Power Lens Rifle Glass Info
A single power rifle scope comes with a magnification 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 kind of optic can not change since it is a set power scope.
Adjustable Power Lens Optics
Variable power rifle scopes use enhanced power. The power change is achieved using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope powers and the ranges where they may be efficiently used. Highly magnified glass will not be as useful as lower powered scopes considering too much zoom can be a bad thing. The same idea relates to longer ranges where the shooter needs adequate power to see where to best aim the rifle at the target.
Lens Finish for Scopes
All contemporary rifle scope lenses are covered. Lens finishing is an essential element of a shooting platform when purchasing high end rifle optics and scope setups.
About Scope Lens Coatings – HD Versus ED
Some scope producers also use “HD” or high-definition lens finishings which use different procedures, components, chemicals, and polarizations to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Info on Single Finishing Versus Multi-Coating
Various optic lenses can also have different coverings applied to them. All lenses generally have at least some type of treatment or covering applied to them before being used in a rifle scope or optic assembly. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It must have a finish put on it so that the lens will be efficiently functional in numerous types of environments, degrees of sunshine (full VS shade), and other shooting conditions.
This lens treatment can offer protection to 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 coated lens depends on the scope producer and how much you paid for it.
Some scope producers similarly make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Details on Anti-water Coating
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic finish.
Options for Installing Optics on Firearms
Mounting options for scopes can be found 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 kinds of mounts also normally are made in quick release versions which use toss levers which enable rifle shooters to rapidly install and remove the scope.
Hex Key Rifle Optic Rings
Basic, clamp-on style 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 two detached rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are designed for long distance accuracy shooting. This kind of scope mount is very good for rifle systems which require a durable, rock solid mount which will not change regardless of just how much the scope is moved or abuse the rifle takes. These are the type of mounts you should have for a faithful optics system on a reach out and touch someone scouting or sniper competition long gun that will pretty much never need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to keep the hex screws from backing out after they are mounted tightly in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. If they all use a similar style mount, multiple scopes can often be switched out in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten tightly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining the original sighting settings. These kinds of mounts are useful and convenient for rifles which are transferred a lot, to take off the glass from the rifle for protection, or for optics which are employed in between a number of rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle optic can destroy a day on the range and your pricey optic by inducing fogging and creating residue within the scope tube. The majority of scopes prevent wetness from entering the optical tube with a series of sealing O-rings which are water resistant. Normally, these optics can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough humidity avoidance for conventional use rifles, unless you anticipate taking your rifle aboard watercrafts and are worried about the optic still functioning if it is submerged in water and you can still retrieve the gun.
Glass Gas Purging
Another part of avoiding the buildup of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is already taken up by the gas, the scope is less affected by temp changes and pressure variations from the outdoor environment which might possibly permit water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
