Optic Details

Rifle scopes enable you to precisely aim a rifle at various targets by aligning your eye with the target at range. They do this through magnifying the target by employing a set of lenses inside the scope. The scope’s positioning can be adjusted for the consideration of many natural aspects like wind and elevation increases or decreases to make up for bullet drop.

The scope’s purpose is to understand precisely where the bullet will hit based upon the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle scopes and optics have about 11 parts which are located internally and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, elevation turrets, objective focus rings, and other components. Learn about the eleven parts of rifle glass.

The Types of Rifle Scopes

Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane a scope has identifies where the reticle or crosshair lies in regard to the optic’s magnification. It simply suggests the reticle is located behind or ahead of the magnification lens of the scope. Choosing the most effective sort of rifle optic is dependent on what type of shooting you plan on undertaking.

First Focal Plane Glass

Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are useful for:

  • Quick acquisition, long distance types of shooting
  • Shooting scenarios where estimations are marginal
  • Experienced shooters who know their target “hold over” and also “lead” equations for their weapon
  • Shooters who do not mind the reticle is bigger and takes up more visual sight space than a SFP reticle

Second Focal Plane Glass Details

Second focal plane scopes (SFP) include the reticle to the rear of the magnifying lens. This causes the reticle to remain at the very same scale in connection with the amount of zoom being used. The outcome is that the reticle dimensions adjust based on the zoom chosen to shoot over greater distances considering the reticle markings represent different increments which fluctuate with the magnification level. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These particular styles of glass work for:

  • Far away kinds of shooting where shooters have more time to make ballistic estimations
  • Shooting where most of the shots take place within much shorter proximities and ranges
  • Shooters who would like a clearer optic picture without area taken up by the larger sized FFP reticle

Rifle Glass Magnification

The quantity of magnification a scope supplies is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.

Fixed Power Lens Rifle Glass Info

A single power rifle optic will have a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not adjust since it is a fixed power scope.

Adjustable Power Lens Rifle Scopes

Variable power rifle scopes use enhanced power. The power change is handled using the power ring part of the scope near the back of the scope by the eye bell.

Rifle Glass Power and Range Correlation

Here are some advised scope power levels and the ranges where they can be successfully used. High power optics will not be as efficient as lower magnification level rifle scope glass due to the fact that too much magnification can be a bad thing. The exact same idea relates to extended distances where the shooter needs to have increased power to see exactly where to properly aim the rifle at the target.

Info on Scope Lens Finish

All modern-day rifle scope and optic lenses are coated. There are various types and qualities of glass lens coatings. Lens coating is an important aspect of a rifle’s setup when thinking about high end rifle optics and targeting units. The lenses are one of the most essential components of the scope as they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses shields the lens surface area and also assists with anti glare capabilities from excess sunlight and color exposure.

HD Versus ED Rifle Glass Lens Coatings

Some scope makers likewise use “HD” or high-definition lens coverings which use different processes, polarizations, chemicals, and aspects to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.

Single Finishing Versus Multi-Coating for Rifle Glass

Various scope lenses can even have different coverings applied to them. All lenses typically have at least some kind of treatment or finishing applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It must have a finishing put on it so that the lens will be optimally usable in numerous types of environments, degrees of light (full light VS shade), and other shooting conditions.

This lens treatment can offer protection to the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.

Some scope makers likewise make it a point to define if their optic lenses are layered or “multi” coated. This indicates the lens has had numerous treatments applied to them. If a lens gets numerous treatments, it can establish that a manufacturer is taking multiple actions to combat different natural aspects like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic covering. This also does not always imply the multi-coated lens will perform much better than a single covered lens. Being “much better” is dependent on the manufacturer’s lens treatment technology and the quality of components used in creating the rifle glass.

Anti-water Glass Lens Finishing

Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic anti-water covering.

Options for Mounting Scopes on Long Guns

Installing approaches for scopes can be found in a couple of choices. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also normally can be found in quick release variations which use toss levers which permit rifle shooters to quickly mount and remove the scope.

Optic Mounting Solutions with Hex Key Rings

Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style 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 is created for long range accuracy shooting. This type of scope mount is great for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abused.

Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to rapidly detach a scope and attach it to a different rifle. Several scopes can even be switched out if they all use a compatible style mount. These types of mounts are handy for rifles which are transported a lot, to swap out the optic from the rifle for protection, or for optics which are used between numerous rifles.

About Glass Tube Sealing and Gas Purging

Moisture inside your rifle scope can destroy a day on the range and your expensive optic by triggering fogging and generating residue inside of the scope tube. Many optics prevent humidity from entering the optical tube with a system of sealing O-rings which are waterproof. Generally, these water-resistant scopes can be submerged under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample wetness avoidance for basic use rifles for hunting and sporting purposes, unless you intend on taking your rifle sailing and are concerned about the optic still functioning if it falls overboard and you can still rescue the firearm.

Optic Gas Purging

Another part of preventing the accumulation of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the glass is less impacted by condition alterations and pressure distinctions from the external environment which could potentially permit 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.
