What You Need to Know About Scopes

Rifle scopes enable you to specifically aim a rifle at various targets by lining up your eye with the target over a distance. They do this through magnifying the target using a series of lenses within the scope. The scope’s positioning can be adapted for consideration of various natural considerations like wind speed and elevation to make up for bullet drop.

The scope’s function is to help shooters understand precisely where the bullet will hit based on the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the target. Most modern rifle scopes and optics have around eleven parts which are found inside and outside of the scope body. These parts include the rifle scope’s body, lenses, modification turrets, focus rings, and other elements. See all eleven parts of a rifle optical system.

The Styles of Rifle Scopes

Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Opting for the finest type of rifle optic is based around what type of shooting you plan on doing.

Info on First Focal Plane Optics

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

  • Quick acquisition, long distance types of shooting
  • Shooting situations where computations are marginal
  • Experienced shooters who know their aim point “hold over” and also “lead” correlations for their firearm
  • Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight room than a SFP reticle

Second Focal Plane Optics

Second focal plane scopes (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.

  • Far away kinds of shooting where shooters have increased time to make ballistic calculations
  • Shooting where most of the shots occur within much shorter distances and ranges
  • Shooters who like a clearer optic picture without room used up by the enlarged FFP reticle

Magnification for Optics

The quantity of scope magnification you need on your scope depends on the sort of shooting you would like to do. Almost every style of rifle optic offers some degree of zoom. The quantity of magnification a scope provides is determined by the size, thickness, and curvatures of the lenses inside of the rifle optic. The magnification of the optic is the “power” of the scope. This means what the shooter is observing through the scope is amplified times the power aspect of what can generally be seen by human eyes.

Fixed Single Power Lens Optics

A single power rifle 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 magnification of this type of optic can not adjust considering that it is a fixed power scope.

Variable Power Lens Optic Facts

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

The Power and Range of Scopes

Here are some recommended scope powers and the distances where they could be efficiently used. Remember that high power optics and scopes will not be as practical as lower powered optics and scopes because too much zoom can be a detractor. 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 modern rifle glass lenses are covered. Lens covering is a significant element of a rifle system when looking at high end rifle optics and scope equipment.

HD Versus ED Lens Coatings

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

Single Covering Versus Multi-Coating

Different optic lenses can also have different finishings applied to them. All lenses usually have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic. This is since the lens isn’t just a raw piece of glass. It becomes part of the finely tuned optic. It must have a coating placed on it so that the lens will be efficiently usable in lots of kinds of environments, degrees of light (full VS shade), and other shooting conditions.

Single layered lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope maker and just how much you spent paying for it. Both the manufacturer and amount are indicators of the lens quality.

Some scope makers also make it a point to specify if their optic lenses are coated or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in building the rifle scope.

Rifle Glass Lens Hydrophobic Coating

Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end scope companies will coat their lenses with a hydrophobic or hydrophilic finish which is water repellent.

Choices for Installing Rifle Scopes on Firearms

Mounting approaches for scopes come in a few options. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also typically come in quick release versions which use throw levers which enable rifle operators to quickly install and dismount the glass.

Scope Mounts with Hex Key Rings

Normal, clamp style 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 two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range precision shooting. This type of scope install is excellent for rifles which require a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abused.

Quick-Release Cantilever Rifle Optic Rings

These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach it to a different rifle. Numerous scopes can even be swapped out if they all use a compatible design mount. These types of mounts are convenient for rifle platforms which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are used in between numerous rifles.

Sealing and Gas Purging for Rifle Optic Tubes

Moisture inside your rifle optic can mess up a day on the range and your pricey optic by triggering fogging and developing residue inside of the scope’s tube. Many optics prevent moisture from going into the optical tube with a series of sealing O-rings which are waterproof. Usually, these water-resistant scopes can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture avoidance for conventional use rifles, unless you anticipate taking your rifle on a boat and are worried about the scope still working if it falls overboard and you can still recover the gun.

Gas Purged Rifle Optic Tubes

Another part of avoiding the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the scope is less impacted by condition shifts and pressure differences from the outdoor environment which could possibly enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
