Optic Facts

Rifle scopes permit you to precisely aim a rifle at different targets by lining up your eye with the target over a distance. They do this through zoom by utilizing a set of lenses inside the scope. The scope’s positioning can be dialed in to take into account separate environmental aspects 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 upon the sight picture you are seeing via the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern rifle scopes and optics have about eleven parts which are arranged inside and externally on the scope. These scope parts consist of the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other components. Learn about the eleven parts of rifle scopes.

The Types of Rifle Scopes

Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the optimal type of rifle optic depends on what type of shooting you plan on doing.

Info on First Focal Plane Optics

Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This triggers the reticle to increase in size based upon the level of zoom being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non amplified range. For example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These types of scopes work for:

  • Quick acquisition, long distance types of shooting
  • Shooting scenarios where calculations are small
  • Experienced shooters who have an idea for their aim point “hold over” and “lead” relationships for their long guns
  • Shooters who do not mind the reticle is enlarged and occupies more visual eyesight space than a SFP reticle

Info About Second Focal Plane Scopes

Second focal plane optics (SFP) feature the reticle to the rear of the magnifying lens. This triggers the reticle to remain at the same scale relative to the volume of zoom being used. The end result is that the reticle measurements evolve based upon the magnification chosen to shoot over lengthier distances due to the fact that the reticle measurements represent different increments which change with the zoom. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These types of glass are useful for:

  • Long distance styles of shooting where shooters have more time to make ballistic calculations
  • Shooting where most of the shots happen within shorter ranges and distances
  • Shooters who would like a clearer optic picture without room used up by the enlarged FFP reticle

Magnification for Rifle Glass

The amount of zoom a scope supplies is determined by the size, 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 Rifle Scope Facts

A single power rifle scope or optic will have a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate because it is set from the factory.

Adjustable Power Lens Optics

Variable power rifle scopes have adjustable power. These types of scopes will note the zoom degree in a configuration such as 2-10×32. These numbers suggest the zoom of the scope could be adjusted between 2x and 10x power. This also utilizes the power levels in-between 2 and 10. The power adjustment is achieved by operating the power ring component of the scope near the rear of the scope by the eye bell.

Power Levels and Range Correlations

Here are some recommended scope power levels and the ranges where they can be successfully used. Bear in mind that higher magnification scopes will not be as practical as lower magnification level scope and optics because too much magnification can be a detractor. The same concept goes for extended ranges where the shooter needs increased power to see exactly where to properly aim the rifle at the target.

Rifle Scope Lens Finish

All top teir rifle optic lenses are covered. Lens finish can be a crucial aspect of a rifle system when looking into high end rifle optics and scope systems.

HD Versus ED Scope Lens Coatings

Some scope producers likewise use “HD” or high-definition lens coverings which use different techniques, polarizations, chemicals, and components to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.

Single Finish Versus Multi-Coating for Glass

Various scope lenses can also have various finishes applied to them. All lenses generally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It must have a covering put on it so that it will be efficiently functional in lots of types of environments, degrees of sunlight (full VS shade), and other shooting conditions.

This lens treatment can protect the lens from scratches while decreasing 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 maker and how much you paid for it.

Some scope makers also make it a point to define if their optic lenses are layered or “multi” covered. Being “better” depends on the maker’s lens treatment technology and the quality of products used in developing the rifle scope.

Hydrophobic Coating for Rifle Scopes

Water on a lens does not help with maintaining 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 covering.

Scope Installation Options

Installing options for scopes come in a few options. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also typically come in quick release variations which use manual levers which enable rifle shooters to quickly install and dismount the optics.

Optic Mounts with Hex Key Rings

Normal, clamp style 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 separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is designed for long range precision shooting. This type of scope mount is perfect for rifles which need a long lasting, sound 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 Mounts

These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. Several scopes can also be swapped out if they all use a complementary style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving the original sighting settings. These kinds of mounts are useful and handy for shooting platforms which are shipped a lot, to take off the scope from the rifle for protection, or for optics which are utilized in between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It normally costs around $250 USD

Info on Rifle Glass Tube Sealing and Gas Purging

Wetness inside your rifle optic can wreck a day on the range and your pricey optic by inducing fogging and creating residue within the scope tube. The majority of scopes protect against moisture from going into the scope tube with a series of sealing O-rings which are waterproof. Usually, these water-resistant 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 plenty of wetness avoidance for basic use rifles for hunting and sporting purposes, unless you anticipate taking your rifle sailing and are worried about the scope still working if it goes over the side and you can still find the gun.

What to Know About Rifle Scope Tube Gas Purging

Another component of avoiding the buildup of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the glass is less impacted by climate changes and pressure variations from the outside environment which may potentially allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
