Dead-Hold BDC MOA Reticle
The customized design of this reticle helps eliminate guesswork on hold-over and windage corrections. Good for hunting and shooting at varying ranges where estimating hold-over is a concern.
Second focal plane (SFP) reticles are located near the scope’s eyepiece behind the image erecting and magnifying lenses. This style of reticle does not visually change in size when you change the magnification. The advantage of an SFP reticle is that it always maintains the same appearance. Listed reticle subtensions used for estimating range, holdover, and wind drift correction are only accurate at one particular magnification.

Information About Rifle Scopes
Rifle scopes permit you to precisely aim a rifle at different targets by lining up your eye with the target at range. They do this through zoom by using a set of lenses within the scope. The scope’s alignment can be adjusted for consideration of different natural elements like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based upon the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle scopes and optics have around 11 parts which are located inside and externally on the optic. These scope parts include the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of rifle scopes.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the perfect type of rifle optic depends on what type of shooting you plan on doing.
First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the amount of magnification being used. The result 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 without “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are very little
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” ratios for their rifles
- Shooters who don’t mind the reticle is bigger and requires more visual sight room than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the magnification 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 reticle measurement.
- Far away forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots take place within shorter ranges and spaces
- Shooters who select a clearer optic picture with less space used up by the enlarged FFP reticle
Rifle Scope Magnification
The amount of zoom a scope offers is determined by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Rifle Scope Info
A single power rifle scope or optic comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not change because it is a set power scope.
Adjustable Power Lens Optic Facts
Variable power rifle scopes use variable power levels. The power modification is handled by the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Optic Power and Ranges
Here are some recommended scope powers and the ranges where they can be successfully used. High power optics will not be as beneficial as lower powered rifle scope glass considering too much magnification can be a negative aspect depending on your shooting distance. The same idea relates to longer distances where the shooter needs to have sufficient power to see where to best aim the rifle.
Lens Finishing for Glass
All modern rifle scope and optic lenses are coated. There are various types and qualities of finishes. When thinking about high end rifle scope setups, Lens finishing can be a crucial element of defining the rifle’s capability. The glass lenses are among the most essential parts of the optic considering that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens exterior and assists with anti glare from excess daylight and color perception.
Details on Lens Coatings – HD Versus ED
Some rifle scope suppliers also use “HD” or high-definition lens coatings which use various procedures, rare earth compounds, aspects, and polarizations to draw out a wide range of colors and viewable definition through the lens. This high-def covering is normally used with more costly high density lens glass which decreases light’s capability to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” signifying 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 is often obvious over objects with well defined outlines as light hits the object from various angles.
Single Rifle Scope Lens Finishing Versus Multi-Coating
Different optic lenses can likewise have different coverings 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.
This lens treatment can protect the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope makers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Hydrophobic Lens Finishing
Water on an optic’s lens doesn’t help with keeping a clear sight picture through an optic in any way. Many top of the line or high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the exterior surfaces of the Steiner scope lens so the water particles can not bind to it or create surface tension. The result is that the water beads move off of the scope to maintain a clear, water free sight picture.
Glass Mounting Alternatives
Mounting options for scopes are available in a couple of options. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also normally are made in quick release versions which use manual levers which allow rifle shooters to quickly mount and dismount the glass.
Rifle Glass Mounts with Hex Key Rings
Normal, 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 two separate rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long range precision shooting. This type of scope mount is great for rifles which require a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and attach it to a different rifle. Several scopes can even be swapped out if they all use a similar design mount. These types of mounts are convenient for long guns which are carried a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles.
What to Know About Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your expensive optic by causing fogging and producing residue inside of the scope tube. Most scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Glass Tubes
Another element of avoiding the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the optic is less affected by condition shifts and pressure distinctions from the outside environment which might possibly enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
