All About Rifle Optics

Rifle scopes allow you to specifically aim a rifle at different targets by lining up your eye with the target over a range. They do this through zoom by employing a set of lenses within the scope. The scope’s alignment can be adapted to account for different natural things like wind speed and elevation increases or decreases to make up for bullet drop.

The scope’s function is to help shooters understand precisely where the bullet will hit based upon the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the target. A lot of modern-day rifle optics have around 11 parts which are arranged internally and externally on the scope. These parts include 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” type of scopes. Choosing the optimal type of rifle scope depends on what type of shooting you plan to do.

First Focal Plane Optics

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

  • Quick acquisition, far away types of shooting
  • Shooting situations where estimations are minimal
  • Experienced shooters who know their aim point “hold over” plus “lead” correlations for their firearms
  • Shooters who do not mind the reticle is enlarged and uses up more visual sight area than a SFP reticle

About Second Focal Plane Scopes

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

  • Long distance types of shooting where shooters have additional time to make ballistic calculations
  • Shooting where most of the shots take place within much shorter ranges and spaces
  • Shooters who choose a clearer optic sight picture with less room used up by the enlarged FFP reticle

Details on Glass Zoom

The quantity of scope zoom you need is based on the type of shooting you like to do. Just about every type of rifle glass offers some level of zoom. The amount of magnification a scope offers is identified by the diameter, density, and curvatures of the lens glass within the rifle optic. The zoom of the optic is the “power” of the scope. This indicates what the shooter is checking out through the scope is amplified times the power factor of what can normally be seen by human eyes.

Fixed Power Lens Rifle Glass

A single power rifle scope and optic comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not fluctuate because it is a fixed power scope.

Variable Power Lens Rifle Glass

Variable power rifle scopes have adjustable power. It will list the zoom degree in a configuration such as 2-10×32. These numbers suggest the magnification of the scope could be adjusted between 2x and 10x power. This additionally involves the power levels in-between 2 and 10. The power manipulation is achieved by working with the power ring component of the scope near the back of the scope by the eye bell piece.

Power and Range Correlations

Here are some suggested scope powers and the ranges where they could be efficiently used. Remember that higher magnification scopes will not be as efficient as lower powered scopes since increased magnification can be a negative thing in certain situations. The same goes for longer ranges where the shooter needs increased power to see exactly where to best aim the rifle at the target.

Lens Covering for Scopes

All current rifle optic lenses are layered. Lens finishing can be a crucial element of a rifle when considering high end rifle optics and scope systems.

HD Versus ED Optic Lens Coatings

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

Single Rifle Glass Lens Finish Versus Multi-Coating

Different optic lenses can likewise have various finishings applied to them. All lenses generally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.

This lens treatment can safeguard the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.

Some scope producers likewise make it a point to define if their optic lenses are covered or “multi” coated. This suggests the lens has several treatments applied to them. If a lens receives numerous treatments, it can prove that a company is taking multiple actions to combat different environmental factors like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This also does not always indicate the multi-coated lens is better than a single coated lens. Being “better” depends on the producer’s lens treatment solutions and the quality of products used in creating the rifle optic.

Hydrophobic Lens Coatings

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

Rifle Scope Installation Choices

Installing solutions for scopes are available in a few options. There are the basic scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release versions which use throw levers which allow rifle shooters to rapidly install and remove the scope.

Rifle Scope Mounting Solutions with Hex Key Rings

Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use a pair of detached rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This form of scope mount is ideal for rifle systems which need to have a long lasting, unfailing mount which will not shift despite how much the scope is moved or abuse the rifle takes. These are the design of mounts you should get for a specialized optics system on a far away scouting or tournament rifle which will seldom need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount screws to prevent the hex screw threads from wiggling out after they are mounted securely in place. An example of these rings are the 30mm style from Vortex Optics. The set generally costs around $200 USD

Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be switched out if they all use a compatible design mount. These types of mounts are convenient for rifles which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between several rifles.

Sealing and Gas Purging for Optic Tubes

Wetness inside your rifle optic can destroy a day of shooting and your costly optic by triggering fogging and generating residue inside of the scope tube. A lot of scopes prevent moisture from going into the optical tube with a series of sealing O-rings which are water resistant. Generally, these water resistant optics can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture avoidance for common use rifles for hunting and sporting purposes, unless you anticipate taking your rifle boating and are worried about the optic still performing if it goes over the side and you can still find the firearm.

Gas Purged Rifle Optic Tubes

Another part of avoiding the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this area is currently occupied by the gas, the scope is less affected by temperature changes and pressure variations from the outdoor environment which could possibly allow water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
