Scope Info

Rifle scopes allow you to exactly align a rifle at various targets by aligning your eye with the target over a distance. They do this through magnifying the target using a set of lenses within the scope. The scope’s alignment can be adapted for the consideration of various environmental considerations like wind and elevation increases to make up for bullet drop.

The scope’s purpose is to understand exactly where the bullet will land based upon the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle optics have around eleven parts which are found internally and outside of the optic. These optic pieces consist of the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other elements. See all eleven parts of a rifle scope.

Rifle Scope Styles

Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane an optic has establishes where the reticle or crosshair lies in connection with the optic’s magnification. It literally suggests the reticle is behind or in front of the magnifying lens of the scope. Looking for the most ideal kind of rifle scope depends upon what style of shooting or hunting you plan on undertaking.

About First Focal Plane Glass

First focal plane scopes (FFP) come with the reticle ahead of the magnification lens. This causes the reticle to increase in size based upon the amount of magnification being used. The outcome is that the reticle measurements are the same at the enhanced distance as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the identical tick at one hundred yards with 5x “zoom”. These kinds of scopes are useful for:

  • Quick acquisition, far away types of shooting
  • Shooting situations where computations are small
  • Experienced shooters who understand their target “hold over” and “lead” ratios for their firearm
  • Shooters who do not mind the reticle is bigger and uses up more visual sight area than a SFP reticle

About Second Focal Plane Scopes

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

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

Rifle Glass Magnification

The level of scope magnification you require is based on the form of shooting you plan to do. Virtually every kind of rifle scope provides some degree of magnification. The quantity of zoom a scope gives is established by the diameter, density, and curvatures of the lenses inside of the rifle optic. The magnification level of the optic is the “power” of the scope. This denotes what the shooter is checking out through the scope is magnified times the power aspect of what can normally be seen by human eyes.

Fixed Power Lens Glass

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

Adjustable Power Lens Glass Info

Variable power rifle scopes have adjustable power. These types of scopes will list the magnification degree in a format such as 2-10×32. These numbers mean the magnification of the scope could be set in between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power shift is accomplished using the power ring part of the scope near the back of the scope by the eye bell.

Power Levels and Range

Here are some suggested scope power levels and the distances where they could be successfully used. Highly magnified rifle scope glass will not be as beneficial as lower magnification optics due to the fact that too much zoom can be a bad thing. The exact same concept relates to longer distances where the shooter needs to have sufficient power to see precisely where to best aim the rifle at the target.

Lens Covering for Optics

All current rifle glass lenses are coated. Lens covering is a vital element of a shooting system when purchasing high end rifle optics and scope equipment.

Details on Rifle Optic Lens Coatings – HD Versus ED

Some scope manufacturers additionally use “HD” or high-definition glass coverings which employ different procedures, aspects, chemicals, and polarizations to extract different color ranges and viewable definition through the lens. This high-def finishing is normally used with more costly high density lens glass which brings down light’s chance to refract through the lens glass. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how certain colors are represented on the chroma spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration can be noticeable over objects with hard edges and shapes as light hits the item from particular angles.

Optic Lens Single Finishing Versus Multi-Coating

Different scope lenses can also have different coatings applied to them. All lenses generally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally functional in many types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.

Single covered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can safeguard the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope company and the amount you paid for it. Both are indicators of the lens quality.

Some scope producers also make it a point to define if their optic lenses are coated or “multi” covered. This suggests the lens has several treatments applied to the surfaces. If a lens receives multiple treatments, it can show that a company is taking multiple steps to combat various natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This additionally doesn’t necessarily imply the multi-coated lens will perform better than a single layered lens. Being “much better” hinges on the manufacturer’s lens treatment technology and the quality of materials used in building the rifle optic.

Rifle Glass Lens Hydrophobic Finish

Water on a lens doesn’t help with preserving a clear sight picture through a scope in any way. Lots of top of the line and high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the surface area of the Steiner optic lens so the water molecules can not bind to it or produce surface tension. The result is that the water beads sheet off of the scope to preserve a clear, water free sight picture.

Optic Mounting Options

Installing options for scopes are available in a couple of options. There are the basic scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also typically are made in quick release variations which use toss levers which allow rifle operators to rapidly install and remove the scopes.

Hex Key Rifle Scope Rings

Standard, clamp type mounting scope rings use hex head screws to fix to the flattop style Picatinny scope mount rails on the tops of rifles. These forms of scope mounts use a pair of detached rings to support the optic, and are normally made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance accuracy shooting. This form of scope mount is good for rifles which are in need of a resilient, hard use mount which will not change regardless of just how much the scope is moved about or abuse the rifle takes. These are the style of mounts you really want to have for a faithful scope setup on a long distance hunting or sniper competition rifle that will seldom need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to stop the hex screw threads from wiggling out after they are installed safely in position. An example of these mounting rings are the 30mm type from the Vortex Optics company. The set usually costs around $200 USD

Quick-Release Cantilever Rifle Optic Ring Mounting Solutions

These types of quick-release rifle scope mounts can be used to rapidly remove a scope and connect it to a different rifle. Several scopes can also be swapped out if they all use a compatible style mount. These types of mounts come in handy for rifle platforms which are carried a lot, to swap out the optic from the rifle for protection, or for optics which are used between multiple rifles or are situationally focused.

What to Know About Glass Tube Sealing and Gas Purging

Wetness inside your rifle optic can ruin a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. Most scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof.

Scope Gas Purging

Another element of avoiding the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the glass is less impacted by climate changes and pressure differences from the outdoor environment which could possibly allow water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
