Rifle Scope Facts

Rifle scopes permit you to specifically aim a rifle at various targets by lining up 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 adjusted for the consideration of varied ecological factors like wind and elevation decreases to account for bullet drop.

The scope’s function is to help shooters understand precisely where the bullet will land based on the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the target. The majority of contemporary rifle optics have about 11 parts which are located within and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other components. See all eleven parts of scopes.

Rifle Glass Varieties

Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane an optic has identifies where the reticle or crosshair is located relative to the optic’s magnifying adjustments. It simply suggests the reticle is located behind or in front of the magnifying lens of the scope. Selecting the very best type of rifle optic is dependent on what type of hunting or shooting you plan on undertaking.

Info About First Focal Plane Glass

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

  • Quick acquisition, long distance kinds of shooting
  • Shooting circumstances where estimations are marginal
  • Experienced shooters who understand their target “hold over” and also “lead” relationships for their rifles
  • Shooters who don’t mind the reticle is bigger and requires more visual sight room than a SFP reticle

About Second Focal Plane Glass

Second focal plane scopes (SFP) include the reticle to the rear of the magnifying lens. This induces the reticle to stay at the exact same scale relative to the volume of zoom being used. The effect is that the reticle measurements adapt based on the magnification applied to shoot over longer distances considering the reticle measurements represent different increments which can vary with the magnification level. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement. These sorts of scopes are useful for:

  • Long distance kinds of shooting where shooters have extra time to make ballistic estimations
  • Shooting where most shots take place within shorter distances and ranges
  • Shooters who select a clearer optic picture with less room used up by the enlarged FFP reticle

Details on Glass Magnification

The quantity of scope zoom you require depends upon the form of shooting you wish to do. Just about every type of rifle optic supplies some degree of zoom. The amount of magnification a scope gives is identified by the size, density, and curves of the lenses inside of the rifle optic. The magnifying level of the scope is the “power” of the opic. This means what the shooter is checking out through the scope is magnified times the power element of what can normally be seen by human eyes.

Single Power Lens Scope Facts

A single power rifle scope or optic will have a zoom number designator like 4×32. This implies 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 because it is a fixed power scope.

Variable Power Lens Glass Details

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

The Power Level and Range of Rifle Glass

Here are some recommended scope power levels and the ranges where they can be successfully used. Highly magnified glass will not be as effective as lower powered rifle scope glass due to the fact that too much zoom can be a bad thing. The exact same concept relates to extended ranges where the shooter needs increased power to see where to best aim the rifle.

About Lens Finishing

All contemporary rifle optic lenses are coated. There are different types and qualities of glass coatings. When considering high end rifle optical setups, Lens finish can be a vital component of a rifle. The glass lenses are one of the most critical pieces of the optic since they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses offers protection to the lens exterior and also improves anti glare capabilities from excess sunrays and color discernibility.

HD Versus ED Lenses

Some optic companies also use “HD” or high-def glass finishes which make the most of various procedures, polarizations, chemicals, and elements to extract different colors and viewable target visibility through the lens. This high-def coating is typically used with higher density lens glass which lowers light’s ability to refract through the lens glass. Some scope makers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious over objects with well defined shapes as light hits the object from specific angles.

Single 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 finish used to them prior to being used in a rifle scope or optic.

Single covered lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can safeguard the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope designer and how much you spent paying for it. Both the make and cost are indications of the lens quality.

Some scope producers similarly make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in constructing the rifle scope.

Glass Lens Anti-water Finish

Water on a scope’s lens doesn’t support maintaining a clear sight picture through a scope in any way. Numerous top of the line or high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It treats the surface area of the Steiner optic lens so the H2O molecules can not bind to it or develop surface tension. The outcome is that the water beads slide off of the scope to maintain a clear, water free sight picture.

Choices for Installing Rifle Optics on Firearms

Installing options for scopes can be found in a couple of choices. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also generally can be found in quick release versions which use manual levers which enable rifle operators to quickly mount and dismount the scope.

Optic Mounting Solutions with Hex Key Rings

Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount 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 distance precision shooting. This type of scope install is excellent for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.

Quick-Release Cantilever Rifle Optic Ring Mounts

These kinds of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle. Multiple scopes can also be switched out if they all use a similar designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining accuracy. These types of mounts come in practical for rifles which are hauled around a lot, to take off the scope glass from the rifle for protection, or for scopes which are adopted between several rifles. An example of this mount style is the 30mm mount from Vortex Optics. It generally costs around $250 USD

Sealing and Gas Purging for Rifle Glass Tubes

Moisture inside your rifle scope can destroy a day of shooting and your pricey optic by triggering fogging and developing residue inside of the scope tube. Most scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are waterproof.

Scope Gas Purging

Another component of avoiding the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the optic is less altered by climate shifts and pressure variations from the outdoor environment which could possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
