Info About Glass
Rifle scopes permit you to exactly aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through zoom by making use of a set of lenses within the scope. The scope’s alignment can be adapted for consideration of varied natural aspects like wind speed and elevation increases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will land based on the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the target. The majority of contemporary rifle optics have about eleven parts which are found within and externally on the optic. These parts consist of the rifle scope’s body, lenses, adjustment dials or 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 scopes. Deciding on the best type of rifle glass depends on what type of shooting you plan to do.
First Focal Plane Optics
First focal plane glass (FFP) feature the reticle ahead of the magnification lens. This causes the reticle to increase in size based upon the level of magnification being used. The result is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. For instance, one tick on a mil-dot reticle at 100 yards without any “zoom” is still the exact same tick at one hundred yards using 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who have an idea for their target “hold over” plus “lead” ratios for their long gun
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the zoom lens. This triggers the reticle to stay at the same overall size relative to the level of magnification being used. The effect is that the reticle dimensions adapt based on the magnification chosen to shoot over greater ranges due to the fact that the reticle measurements represent distinct increments which vary with the magnification level. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular types of scopes are convenient for:
- Long distance types of shooting where shooters have more time to make ballistic computations
- Shooting where most shots take place within shorter spaces and ranges
- Shooters who choose a clearer optic sight picture without room taken up by the larger size FFP reticle
Magnification for Optics
The extent of scope magnification you need on your optic is based on the style of shooting you intend to do. Just about every type of rifle glass offers some amount of magnification. The volume of magnification a scope gives is determined by the diameter, thickness, and curves of the lenses within the rifle optic. The magnification level of the optic is the “power” of the glass. This signifies what the shooter is observing through the scope is magnified times the power element of what can usually be seen by human eyes.
Fixed Single Power Lens Glass Details
A single power rifle scope comes with a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not adjust because it is set from the factory.
Variable Power Lens Glass Details
Variable power rifle scopes use enhanced power. The power modification is performed using the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some advised scope power settings and the ranges where they may be effectively used. Remember that higher magnification glass will not be as efficient as lower powered optics since increased magnification can be a detractor. The exact same idea goes for longer ranges where the shooter needs adequate power to see where to best aim the rifle at the target.
About Rifle Glass Lens Finishes
All top teir rifle scope and optic lenses are coated. Lens covering is an essential aspect of a shooting system when buying high end rifle optics and scope systems.
Info on Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens coatings which use different processes, aspects, chemicals, and polarizations to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Coating Versus Multi-Coating
Different optic lenses can also have various coatings used to them. All lenses generally have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to 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 layered lens depends on the scope manufacturer and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the producer’s lens treatment innovation and the quality of materials used in building the rifle scope.
Rifle Glass Lens Anti-water Coating
Water on a lens does not assist with preserving 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 hydrophilic or hydrophobic coating.
Alternatives for Mounting Scopes on Firearms
Mounting options for scopes are available in a couple of choices. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also normally come in quick release versions which use manual levers which enable rifle shooters to quickly install and dismount the glass.
Hex Key Rifle Scope Ring Mounting Solutions
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope install is great for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. Several scopes can also be swapped out if they all use a complementary designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten securely 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 maintaining accuracy. These kinds of mounts are useful and beneficial for shooting platforms which are moved around a lot, to remove the optic from the rifle for protection, or for sight systems which are chosen for use in between multiple rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle scope can spoil a day on the range and your expensive optic by inducing fogging and developing residue within the scope tube. Many optics prevent wetness from getting in the scope tube with a system of sealing O-rings which are water resistant. Usually, these optics can be submerged under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture content avoidance for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle on your motorboat and are concerned about the optic still working if it goes over the side and you can still salvage the firearm.
Info Around Rifle Glass Tube Gas Purging
Another part of avoiding the accumulation of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is currently taken up by the gas, the optic is less impacted by condition changes and pressure variations from the outside environment which might potentially allow water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
