All About Rifle Scopes

Rifle scopes allow you to specifically align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by making use of a set of lenses inside the scope. The scope’s positioning can be adapted for the consideration of numerous ecological elements like wind and elevation increases or decreases to make up for bullet drop.

The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes and optics have around 11 parts which are arranged within and outside of the scope body. These scope parts include the rifle scope’s body, lenses, elevation dials, focus rings, and other elements. Learn about the eleven parts of optics.

The Varieties of Rifle Scopes

Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane a scope has identifies where the reticle or crosshair lies in relation to the optic’s magnifying adjustments. It simply indicates the reticle is situated behind or in front of the magnification lens of the scope. Looking for the very best kind of rifle optic depends upon what variety of shooting you intend on doing.

First Focal Plane Scopes

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

  • Quick acquisition, far away types of shooting
  • Shooting scenarios where calculations are low
  • Experienced shooters who understand their aim point “hold over” and “lead” relationships for their weapon
  • Shooters who do not mind the reticle is enlarged and requires more visual sight space than a SFP reticle

About Second Focal Plane Optics

Second focal plane glass (SFP) come with the reticle behind the magnifying lens. This triggers the reticle to remain at the very same overall size in relation to the amount of zoom being used. The final result is that the reticle dimensions change based on the magnification employed to shoot over longer ranges because the markings represent different increments which can vary 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 reticle measurement. These sorts of optics are convenient for:

  • Far away styles of shooting where shooters have more time to make ballistic computations
  • Shooting where most of the shots happen within much shorter ranges and distances
  • Shooters who would like a clearer optic sight picture without area taken up by the larger sized FFP reticle

Magnification for Rifle Optics

The quantity of zoom a scope offers is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.

Fixed Power Lens Scopes

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

Info About Adjustable Power Lens Optics

Variable power rifle scopes use variable power levels. The power modification is performed by the power ring part of the scope near the back of the scope by the eye bell.

Power Levels and Range Correlations

Here are some recommended scope powers and the distances where they may be effectively used. Highly magnified glass will not be as useful as lower powered scopes due to the fact that too much magnification can be a bad thing. The very same idea applies to extended ranges where the shooter needs to have sufficient power to see where to best aim the rifle at the target.

About Lens Finishes

All contemporary rifle glass lenses are coated. Lens finish is an essential aspect of a rifle when considering high end rifle optics and scope equipment.

HD Versus ED Glass Lens Coatings

Some scope makers also use “HD” or high-definition lens coatings which use various methods, polarizations, elements, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.

Optic Lens Single Finishing Versus Multi-Coating

Various optic lenses can also have different finishes applied to them. All lenses normally have at least some kind of treatment or finishing applied to them before being used in a rifle scope or optic. This is because the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It must have a coating applied to it so that it will be efficiently functional in numerous types of environments, degrees of sunshine (full VS shaded), and other shooting conditions.

This lens treatment can offer protection to the lens from scratches while decreasing glare and other less advantageous 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 producers similarly make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the producer’s lens treatment innovation and the quality of products used in building the rifle scope.

Anti-water Lens Coverings

Water on a lens does not help with keeping a clear sight picture through a scope at all. Lots of top of the line and military grade scope makers will coat their lenses with a hydrophobic or hydrophilic covering.

Choices for Installing Optics on Firearms

Mounting approaches for scopes are available in a couple of options. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also generally are made in quick release variations which use toss levers which permit rifle operators to rapidly install and dismount the scopes.

Glass Mounting Solutions with Hex Key Rings

Standard, 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 two different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long range precision shooting. This type of scope install is perfect for rifles which require a resilient, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.

Quick-Release Cantilever Scope Ring Mounts

These kinds of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle. A wide range of scopes can also be switched out if they all use a complementary style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping the original sighting settings. These kinds of mounts are useful and handy for rifles which are moved a lot, to remove the optic from the rifle for protection, or for scopes which are adopted between a number of rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It generally costs around $250 USD

Info Around Rifle Optic Tube Sealing and Gas Purging

Wetness inside your rifle optic can destroy a day of shooting and your expensive optic by causing fogging and creating residue inside of the scope tube. The majority of scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are water resistant.

Gas Purged Rifle Scope Tubes

Another part of preventing the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the scope is less altered by temperature changes and pressure differences from the external environment which might potentially allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
