What You Need to Know About Rifle Optics

Rifle scopes enable you to precisely align a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by using a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of different ecological things like wind and elevation to account 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 optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of modern rifle scopes have about 11 parts which are arranged internally and on the exterior of the scope. These scope parts consist of the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other elements. See all eleven parts of a rifle scope.

Rifle Scope Types

Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the finest type of rifle glass is based around what type of shooting you plan to do.

First Focal Plane Optic Facts

Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are beneficial for:

  • Quick acquisition, long distance types of shooting
  • Shooting circumstances where calculations are very little
  • Experienced shooters who recognize their target “hold over” and also “lead” correlations for their long guns
  • Shooters who do not mind the reticle is bigger and requires more visual sight room than a SFP reticle

Second Focal Plane Glass Details

Second focal plane optics (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement.

  • Far away styles of shooting where shooters have additional time to make ballistic computations
  • Shooting where most shots occur within much shorter distances and ranges
  • Shooters who choose a clearer optic picture with less room taken up by the enlarged FFP reticle

Optic Magnification

The extent of scope zoom you need on your optic depends upon the form of shooting you would like to do. Nearly every kind of rifle scope gives some level of magnification. The level of zoom a scope offers is established by the diameter, thickness, and curvatures of the lens glass inside of the rifle optic. The magnification level of the scope is the “power” of the glass. This suggests what the shooter is checking out through the scope is amplified times the power element of what can usually be seen by human eyes.

Fixed Power Lens Glass Facts

A single power rifle optic and scope uses a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not change considering that it is a fixed power optic.

Adjustable Power Lens Rifle Scopes

Variable power rifle scopes can be changed between magnification power levels. It will list the zoom degree in a format such as 2-10×32. These numbers imply the magnification of the scope could be set in between 2x and 10x power. This always involves the powers in-between 2 and 10. The power shift is accomplished utilizing the power ring part of the scope near the rear of the scope by the eye bell.

Power and Range Correlations

Here are some suggested scope powers and the ranges where they can be efficiently used. High power rifle scope glass will not be as effective as lower powered glass considering that too much magnification can be a negative aspect depending on your shooting distance. The exact same concept relates to longer distances where the shooter needs to have enough power to see precisely where to best aim the rifle.

Rifle Scope Lens Finish

All modern-day rifle optic and scope lenses are layered. There are various types and qualities of coatings. Lens covering is a crucial element of a rifle when considering high end rifle optics and scope systems. The glass lenses are one of the most important pieces of the optic due to the fact that they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses offers protection to the lens surface area and helps with anti glare from excess sunlight and color exposure.

HD Versus ED Rifle Scope Lens Coatings

Some scope brands also use “HD” or high-definition lens coatings which use different procedures, chemicals, components, and polarizations to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.

Single Optic Lens Coating Versus Multi-Coating

Various scope lenses can also have various finishes applied to them. All lenses normally have at least some kind of treatment or coating 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 is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be optimally usable in lots of types of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.

This lens treatment can offer protection to the lens from scratches while lowering glare and other less advantageous 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 manufacturers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of products used in constructing the rifle scope.

Hydrophobic Covering for Scopes

Water on a lens doesn’t assist with maintaining 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 finishing.

Scope Mounting Options

Installing solutions for scopes can be found in a couple of choices. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also usually come in quick release versions which use manual levers which permit rifle operators to quickly mount and remove the scopes.

Hex Key Optic Rings

Normal, 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 made from 7075 T6 billet aluminum which are developed for long range accuracy shooting. This type of scope mount is fine for rifles which need a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.

Glass Mounting Solutions with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to quickly take off a scope and connect it to a different rifle. Several scopes can also be swapped out if they all use a similar style mount. These types of mounts are handy for long guns which are transported a lot, to remove the optic from the rifle for protection, or for optics which are used between several rifles or are situationally focused.

What to Know About Rifle Optic Tube Sealing and Gas Purging

Moisture inside your rifle optic can mess up a day of shooting and your costly optic by triggering fogging and creating residue inside of the scope tube. Most scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant.

Details on Glass Tube Gas Purging

Another part of avoiding the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the optic is less altered by climate shifts and pressure variations from the outside environment which may potentially enable 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.
