Deadhold-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 scopes 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.
Adjustment Graduation: 1/4 MOA

Rifle Scope Info
Rifle scopes permit you to specifically aim a rifle at different targets by aligning your eye with the target at range. They do this through magnification by employing a set of lenses inside the scope. The scope’s alignment can be dialed in for the consideration of separate ecological elements like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to understand exactly where the bullet will land based on the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle optics have about eleven parts which are arranged inside and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other parts. See all eleven parts of optics.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the perfect type of rifle optic is based on what type of shooting you plan on doing.
Info About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This causes the reticle to increase in size based on the level of magnification being used. The result is that the reticle measurements are the same at the enhanced range 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 very same tick at one hundred yards by using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where estimations are minor
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” equations for their firearm
- Shooters who do not mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Far away styles of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and proximities
- Shooters who like a clearer optic sight picture without space taken up by the larger size FFP reticle
Rifle Optic Magnification
The amount of scope zoom you require depends on the kind of shooting you plan to do. Nearly every kind of rifle scope supplies some amount of magnification. The volume of zoom a scope offers is identified by the size, thickness, and curves of the lens glass inside of the rifle optic. The magnification of the scope is the “power” of the opic. This indicates what the shooter is looking at through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Fixed Power Lens Rifle Glass Facts
A single power rifle optic and scope will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not change given that it is set from the factory.
Adjustable Power Lens Rifle Glass Info
Variable power rifle scopes use enhanced power. The power modification is achieved using the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Optics
Here are some suggested scope power levels and the ranges where they could be successfully used. High power rifle scope glass will not be as useful as lower magnification scopes considering too much magnification can be a bad thing. The exact same idea goes for longer ranges where the shooter needs to have adequate power to see exactly where to best aim the rifle.
Optic Lens Finishing
All modern rifle optic and scope lenses are covered in special coatings. There are various types and qualities of glass lens coverings. When looking at high end rifle optical systems, Lens covering can be an essential component of defining the rifle’s capability. The lenses are among the most crucial pieces of the scope given that they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses safeguards the lens surface and assists with anti glare capabilities from excess sunlight and color discernibility.
HD Versus ED Rifle Scope Lens Coatings
Some glass makers even use “HD” or high-def glass finishes which make the most of different procedures, polarizations, aspects, and chemicals to draw out numerous color ranges and viewable target definition through the lens. This high-def covering is commonly used with greater density lens glass which decreases light’s chance to refract through the lens glass. Some scope suppliers use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious around things with hard outlines as light hits the item from particular angles.
Single Optic Lens Finish Versus Multi-Coating
Various optic lenses can also have various finishings applied to them. All lenses normally have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in numerous types of environments, degrees of light (full light VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of products used in building the rifle scope.
Anti-water Rifle Optic Lens Finishing
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Numerous top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic covering.
Rifle Optic Installing Options
Mounting approaches for scopes are available in a couple of choices. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also typically come in quick release variations which use toss levers which enable rifle shooters to rapidly install and dismount the scopes.
Rifle Optic Mounting Solutions with Hex Key Rings
Normal, clamp style 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 is developed for long range precision shooting. This type of scope install is excellent for rifles which require a durable, 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 types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a compatible style mount. These types of mounts are handy for long guns which are carried a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between multiple rifles or are situationally focused.
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle scope can destroy a day of shooting and your highly-priced optic by resulting in fogging and producing residue within the scope’s tube. The majority of scopes protect against humidity from going into the scope tube with a system of sealing O-rings which are waterproof. Usually, these water resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture prevention for basic use rifles for hunting and sporting purposes, unless you anticipate taking your rifle sailing and are concerned about the scope still functioning if it goes over the side and you can still find the gun.
Gas Purged Optic Tubes
Another component of preventing the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the scope is less altered by temperature shifts and pressure variations from the external 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 decent rifle scope to look for.
