Dual use for Shooting Tactical/Hunting.
EBR-2B MRAD Reticle
The EBR-2B (Enhanced Battle Reticle) is a ranging reticle using MRAD-based subtension lines for ranging, holdover, and windage corrections. Heavier windage dot references on the drop lines increase visibility at all magnifications as well as during low light conditions. Numbered subtensions on the crosshairs ensure quick and easy referencing.
Illuminated reticle provides precise aiming under low-light conditions.
First focal plane (FFP) reticles are located near the windage and elevation turrets in front of the image-erecting and magnifying lenses. This style of reticle will visually grow and shrink as you change the magnification. The main advantage of an FFP reticle is that the reticle subtensions used for ranging, holdovers, and wind drift corrections are consistent at all magnifications. The reticle is heavier at higher magnifications and finer at lower magnifications.

Optic Facts
Rifle scopes permit you to precisely aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target by utilizing a series of lenses within the scope. The scope’s positioning can be adapted for the consideration of varied environmental aspects like wind speed and elevation increases to make up 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 optic as you line up the scope’s crosshair or reticle with the target. The majority of modern rifle scopes have around eleven parts which are found within and outside of the scope body. These parts include the rifle scope’s body, lenses, elevation dials, objective focus rings, and other parts. See all eleven parts of scopes.
About Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the perfect type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Scopes
First focal plane glass (FFP) feature the reticle before the zoom lens. This causes the reticle to increase in size based upon the amount 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 distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at 100 yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are low
- Experienced shooters who have an idea for their target “hold over” and “lead” correlations for their firearms
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane scopes (SFP) come with the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away types of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots happen within shorter ranges and spaces
- Shooters who desire a clearer optic sight picture without room used up by the larger size FFP reticle
About Rifle Optic Zoom
The amount of magnification a scope provides 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 Glass Facts
A single power rifle optic and scope will have a magnification 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 scope can not adjust given that it is set from the factory.
Adjustable Power Lens Rifle Optic Facts
Variable power rifle scopes use variable power levels. The power adjustment is performed using the power ring part of the scope near the back of the scope by the eye bell.
Rifle Optic Power Level and Range Correlation
Here are some recommended scope power settings and the ranges where they could be successfully used. Highly magnified glass will not be as efficient as lower magnification glass due to the fact that too much zoom can be a bad thing. The exact same concept applies to longer distances where the shooter needs to have sufficient power to see exactly where to best aim the rifle.
Rifle Glass Lens Finish
All contemporary rifle scope lenses are coated. Lens finish can be a crucial aspect of a rifle system when considering high end rifle optics and scope equipment.
ED Versus HD Scopes
Some rifle scope producers also use “HD” or high-def lense coatings which take advantage of various processes, polarizations, elements, and chemicals to draw out different color ranges and viewable target visibility through lenses. This HD covering is typically used with higher density glass which drops light’s potential to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be obvious around things with hard edges and outlines as light hits the object from particular angles.
Single Coating Versus Multi-Coating for Scopes
Various optic lenses can likewise have different coverings used to them. All lenses usually have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you paid for it.
Some scope manufacturers likewise make it a point to specify if their optic lenses are layered or “multi” coated. This means the lens has numerous treatments applied to the surfaces. If a lens receives multiple treatments, it can show that a company is taking numerous steps to fight different natural aspects like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This additionally does not always mean the multi-coated lens will perform better than a single coated lens. Being “better” depends on the maker’s lens treatment technology and the quality of glass used in developing the rifle glass.
Hydrophobic Covering for Optics
Water on a scope lens doesn’t support preserving a clear sight picture through a scope whatsoever. Numerous top of the line or high-end scope producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It provides protection for the surface area of the Steiner glass lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Alternatives for Installing Glass on Firearms
Mounting solutions for scopes are available in a few options. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally come in quick release variations which use toss levers which permit rifle shooters to rapidly mount and dismount the glass.
Hex Key Glass Ring Mounts
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long range accuracy shooting. This type of scope mount is great for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. Several scopes can also be swapped out if they all use a complementary designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining precision. These types of mounts are useful and handy for shooting platforms which are carried a lot, to remove the glass from the rifle for protection, or for optics which are utilized between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It normally costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day on the range and your pricey optic by resulting in fogging and making residue within the scope tube. The majority of optics protect against wetness from getting in the scope tube with a system of sealing O-rings which are waterproof. Normally, these optics can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient wetness prevention for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still working if it goes overboard and you can still salvage the firearm.
Rifle Scope Gas Purging
Another element of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the glass is less impacted by temperature shifts and pressure distinctions from the external environment which could possibly enable 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.
