Scope Details

Rifle scopes permit you to precisely align a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification by making use of a series of lenses within the scope. The scope’s positioning can be adapted for consideration of numerous environmental elements like wind speed and elevation decreases to make up for bullet drop.

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

Rifle Scope Styles

Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the finest type of rifle optic depends on what type of shooting you plan to do.

First Focal Plane Scope Facts

First focal plane optics (FFP) include the reticle before the magnifying lens. This induces the reticle to increase in size based on the level of zoom being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These types of scopes are practical for:

  • Quick acquisition, long distance kinds of shooting
  • Shooting scenarios where estimations are minimal
  • Experienced shooters who understand their target “hold over” as well as “lead” correlations for their firearm
  • Shooters who do not mind the reticle is bigger and occupies more visual sight space than a SFP reticle

Second Focal Plane Optic Info

Second focal plane glass (SFP) include the reticle to the rear of the zoom lens. This triggers the reticle to remain at the very same scale relative to the volume of magnification being used. The end result is that the reticle measurements alter based upon the zoom used to shoot over lengthier distances considering the markings present different increments which differ with the magnification level. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular styles of optics are handy for:

  • Far away kinds of shooting where shooters have additional time to make ballistic computations
  • Shooting where most shots take place within shorter ranges and distances
  • Shooters who would like a clearer optic sight picture with less space taken up by the larger sized FFP reticle

Rifle Scope Zoom

The extent of scope magnification you need on your glass depends on the style of shooting you desire to do. Practically every kind of rifle scope delivers some amount of zoom. The volume of zoom a scope provides is identified by the dimension, density, and curvatures of the lens glass within the rifle optic. The magnifying level of the optic is the “power” of the glass. This means what the shooter is checking out through the scope is amplified times the power aspect of what can typically be seen by human eyes.

About Fixed Single Power Lens Glass

A single power rifle scope and optic comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not fluctuate considering that it is a set power scope.

Variable Power Lens Optic Details

Variable power rifle scopes have adjustable power. It will note the magnification amount in a format like 2-10×32. These numbers mean the magnification of the scope could be set in between 2x and 10x power. This also utilizes the powers in-between 2 and 10. The power adjustment is achieved by operating the power ring part of the scope near the rear of the scope by the eye bell.

Scope Power Level and Range Correlation

Here are some advised scope powers and the ranges where they may be efficiently used. Highly magnified optics will not be as efficient as lower powered scopes considering too much magnification can be a negative aspect depending on your shooting distance. The exact same idea goes for longer ranges where the shooter needs to have enough power to see exactly where to best aim the rifle.

Lens Covering for Rifle Optics

All modern-day rifle scope and optic lenses are layered. Lens finish can be an essential aspect of a shooting system when purchasing high end rifle optics and scope equipment.

ED Versus HD Optics

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

Details on Single Covering Versus Multi-Coating

Various optic lenses can likewise have different coatings used to them. All lenses normally have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.

This lens treatment can safeguard the lens from scratches while minimizing 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 similarly make it a point to specify if their optic lenses are covered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle scope.

Anti-water Lens Finishing

Water on an optical lens does not support maintaining a clear sight picture through an optic whatsoever. Numerous top of the line or high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the exterior of the Steiner optic lens so the water particles can not bind to it or produce surface tension. The result is that the water beads sheet off of the scope to maintain a clear, water free sight picture.

Choices for Installing Scopes on Firearms

Mounting solutions for scopes can be found in a couple of options. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally can be found in quick release versions which use toss levers which allow rifle operators to quickly install and dismount the optics.

Hex Key Optic Ring Mounting Solutions

Basic, clamp-on type mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on rifles. These styles of scope mounts use two detached rings to support the optic, and are normally made from 7075 T6 billet aluminum which are made for far away accuracy shooting. This type of scope mount is excellent for rifle systems which need a durable, unfailing mount which will not move despite how much the scope is moved or abuse the rifle takes. These are the type of mounts you want for a specialized optics setup on a far away hunting or competitors rifle that will almost never need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to keep the hex screws from backing out after they are mounted securely in position. An example of these rings are the 30mm style from Vortex Optics. The set normally costs around $200 USD

Quick-Release Cantilever Scope Ring Mounting Solutions

These types of quick-release rifle scope mounts can be used to quickly take off a scope and attach it to a different rifle. Numerous scopes can also be swapped out if they all use a similar style mount. These types of mounts come in handy for rifle platforms which are carried a lot, to remove the optic from the rifle for protection, or for optics which are used in between multiple rifles.

Sealing and Gas Purging for Glass Tubes

Wetness 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. A lot of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.

Rifle Optic Gas Purging

Another component of preventing the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the scope is less altered by condition changes and pressure distinctions from the outside environment which may potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
