Scope Facts

Rifle scopes enable you to precisely aim a rifle at various targets by aligning your eye with the target over a range. They do this through magnifying the target by using a series of lenses within the scope. The scope’s positioning can be dialed in for consideration of different environmental elements like wind speed and elevation decreases 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 seeing through the optic as you align the scope’s crosshair or reticle with the intended target. A lot of modern rifle optics have around eleven parts which are arranged internally and on the exterior of the scope body. These scope parts include the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other components. Learn about the eleven parts of scopes.

Rifle Optic Varieties

Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane a scope has establishes where the reticle or crosshair lies relative to the scopes magnification. It simply indicates the reticle is situated behind or before the magnification lens of the optic. Deciding upon the most effective sort of rifle glass depends upon what variety of hunting or shooting you plan on undertaking.

About 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, long distance types of shooting
• Shooting scenarios where calculations are marginal
• Experienced shooters who recognize their aim point “hold over” plus “lead” correlations for their rifles
• Shooters who don’t mind the reticle is bigger and requires more visual eyesight space than a SFP reticle

About Second Focal Plane Glass

Second focal plane optics (SFP) feature 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.

• Long distance kinds of shooting where shooters have extra time to make ballistic estimations
• Shooting where most of the shots happen within shorter spaces and ranges
• Shooters who choose a clearer optic sight picture without room used up by the bigger FFP reticle

Magnification for Rifle Optics

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

Fixed Power Lens Rifle Scope Details

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 kind of scope can not fluctuate considering that it is a set power scope.

Adjustable Power Lens Scope Details

Variable power rifle scopes use enhanced power. The power modification is handled by using 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 power levels and the ranges where they could be effectively used. Remember that high magnification scopes will not be as effective as lower powered scope and optics since too much magnification can be a bad thing. The same idea relates to extended distances where the shooter needs to have increased power to see precisely where to properly aim the rifle.

Details on Lens Finishing

All modern-day rifle optic and scope lenses are coated. There are various types and qualities of lens finishes. Lens finishing is an essential aspect of a rifle when contemplating luxury rifle optics and targeting equipment. The lenses are one of the most essential parts of the scope considering they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses safeguards the lens surface area and even assists with anti glare from excess natural light and color perception.

HD Versus ED Lens Coatings

Some optic suppliers will also use “HD” or high-def lens coverings that apply different processes, elements, chemicals, and polarizations to extract separate color ranges and viewable definition through the lens. This HD finishing is normally used with higher density glass which drops light’s ability to refract through the lens glass. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration is often obvious over items with hard edges and outlines as light hits the item from various angles.

Scope Lens Single Finish Versus Multi-Coating

Different optic lenses can also have various coatings used to them. All lenses generally have at least some type of treatment or finishing used 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 beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it.

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

Anti-water Lens Coatings

Water on an optical lens doesn’t support keeping a clear sight picture through an optic at all. Many top of the line or high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the surface area of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The result is that the water beads sheet off of the scope to maintain a clear, water free sight picture.

Choices for Installing Rifle Scopes on Long Guns

Installing options 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 types of mounts also usually can be found in quick release versions which use throw levers which permit rifle operators to quickly install and dismount the scope.

Hex Key Scope Ring Mounting Solutions

Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This type of scope mount is perfect for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abused.

Rifle Optic Mounts with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a similar design mount. These types of mounts come in handy for rifle platforms which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles.

Sealing and Gas Purging for Rifle Scope Tubes

Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. Most scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are water resistant.

Rifle Optic Gas Purging

Another element of preventing the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the scope is less affected by temp changes and pressure variations from the external environment which could possibly allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
