Rifle Glass Information
Rifle scopes enable you to precisely aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom by using a set of lenses within the scope. The scope’s alignment can be adjusted for consideration of varied environmental things like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based upon the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle scopes have about eleven parts which are located inside and on the exterior of the scope. These scope parts consist of the rifle scope’s body, lenses, elevation turrets, focus rings, and other parts. Learn about the eleven parts of rifle glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the finest type of rifle glass is based around what type of shooting you plan to do.
About First Focal Plane Glass
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 level of magnification being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the exact 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 calculations are very little
- Experienced shooters who understand their aim point “hold over” plus “lead” ratios for their firearms
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Scope Info
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- 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 distances and ranges
- Shooters who choose a clearer optic sight picture with less room used up by the larger size FFP reticle
Zoom for Scopes
The amount of zoom a scope offers is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Scopes
A single power rifle optic uses a magnification 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 type of scope can not change since it is fixed.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes use variable power levels. The power change is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Glass Power Level and Range Correlation
Here are some advised scope power settings and the distances where they may be effectively used. High power glass will not be as effective as lower powered scopes considering that too much magnification can be a bad thing. The same idea relates to longer ranges where the shooter needs to have increased power to see where to best aim the rifle.
About Lens Covering
All state-of-the-art rifle scope lenses are layered. Lens covering can be an important element of a shooting platform when thinking about high end rifle optics and scope equipment.
HD Versus ED Lenses
Some scope brands likewise use “HD” or high-definition lens finishings which use various methods, chemicals, aspects, and polarizations to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Optics
Various optic lenses can also have different coverings used to them. All lenses usually have at least some type of treatment or finishing used to them before they are used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. This lens treatment can shield the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends on the scope maker and just how much you paid for it. Both are signs of the lens quality.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” coated. This suggests the lens has multiple treatments applied to the surfaces. If a lens receives numerous treatments, it can indicate that a company is taking multiple steps to fight different natural aspects like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic covering. This also does not necessarily mean the multi-coated lens is much better than a single covered lens. Being “much better” hinges on the maker’s lens treatment technology and the quality of components used in building the rifle scope.
Details on Anti-water Covering
Water on a lens does not help with maintaining a clear sight picture through an optic whatsoever. Lots of top of the line or high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the surface of the Steiner glass lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Choices for Installing Rifle Scopes on Long Guns
Mounting approaches for scopes are available in a few choices. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also typically can be found in quick release variations which use toss levers which enable rifle operators to quickly mount and dismount the scope.
Hex Key Rifle Optic Rings
Standard, clamp-on design mounting optic 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 double individual rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are developed for far away accuracy shooting. This form of scope mount is great for rifle systems which require a resilient, rock solid mount which will not shift regardless of how much the scope is moved or abuse the rifle takes. These are the design of mounts you should get for a specialized scope system on a long distance hunting or tournament rifle which will pretty much never need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on screws to prevent 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 the Vortex Optics company. The set generally costs around $200 USD
Quick-Release Cantilever Scope Rings
These kinds of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle. Multiple scopes can also be switched out if they all use a similar style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining accuracy. These kinds of mounts come in practical for shooting platforms which are transferred a lot, to take off the glass from the rifle for protection, or for aiming systems which are used in between multiple rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle optic can wreck a day on the range and your pricey optic by resulting in fogging and making residue inside of the scope’s tube. A lot of scopes protect against humidity from getting in the optical tube with a system of sealing O-rings which are waterproof. Generally, these water-resistant scopes can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture content prevention for common use rifles, unless you anticipate taking your rifle on boats and are concerned about the scope still working if it goes over the side and you can still salvage the gun.
Info Around Rifle Scope Tube Gas Purging
Another component of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the glass is less impacted by temperature level changes and pressure variations from the external environment which might potentially permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
