Trijicon TA02-C-100431 ACOG 4×32 LED Battery Illuminated Red Crosshair 300 Blackout Ballistic Reticle with TA51 Mount
With the same rugged precision as the legendary Trijicon ACOG, the Trijicon 4×32 Battery ACOG delivers robust engineering and enhanced user control. Powered by a single AA battery, the electronics offer an outstanding level of reliability with a straightforward brightness dial, allowing the operator to determine how much to illuminate the reticle-even in transitional lighting. The body has been optimized by moving the RMR mount forward to maximize its performance in conjunction with the ACOG. Fully night vision device compatible, the Trijicon 4×32 Battery ACOG is also compatible with most other 4×32 ACOG accessories available. The 300 blackout reticle with merged aiming points has been optimized for simplicity and efficiency. It allows the user to instantly switch between supersonic and subsonic ammunition without having to re-zero the weapon. The supersonic BDC (out to 600 yds.) has been merged with the subsonic BDC (out to 200 yds.) to provide one set of aiming points for both types of ammunition. The reticle drops are based on an average of commonly available off-the-shelf subsonic and supersonic ammunition. This BDC reticle is not limited to one or two specific bullets: a majority of commonly available ammunition will fall within the 2 MOA diamond aiming points. The 2 MOA diamonds offer a balance of speed and versatility based on the unique performance of the 300 Blackout caliber. The drops for each aiming point are provided for users who wish to develop their own handloads, or for those who wish to deviate from the recommended zero distances.

All About Scopes
Rifle scopes permit you to precisely aim a rifle at different targets by aligning your eye with the target over a range. They do this through magnifying the target by using a series of lenses inside the scope. The scope’s positioning can be adjusted to account for separate ecological aspects like wind and elevation to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle scopes have about 11 parts which are arranged within and outside of the scope body. These scope parts consist of the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other elements. See all eleven parts of a scope.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The sort of focal plane an optic has decides where the reticle or crosshair is located relative to the scopes magnification. It literally implies the reticle is situated behind or before the magnifying lens of the scope. Deciding upon the most suitable kind of rifle glass depends on what type of hunting or shooting you anticipate undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, long distance kinds 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 takes up more visual sight room than a SFP reticle
Second Focal Plane Scope Details
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. This triggers the reticle to stay at the exact same scale in relation to the amount of magnification being used. The result is that the reticle dimensions alter based upon the zoom employed to shoot over lengthier distances since the reticle measurements present various increments which can vary with the magnification. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular types of optics are useful for:
- Far away types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and proximities
- Shooters who choose a clearer optic picture with less room used up by the enlarged FFP reticle
Details on Scope Zoom
The amount of zoom a scope provides is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Rifle Glass Info
A single power rifle scope comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not adjust considering that it is a fixed power scope.
Adjustable Power Lens Rifle Optic Info
Variable power rifle scopes can be adjusted between magnification increments. It will note the zoom level in a configuration like 2-10×32. These numbers mean the zoom of the scope can be adjusted in between 2x and 10x power. This always includes the power levels in-between 2 and 10. The power adjustment is accomplished utilizing the power ring component of the scope near the rear of the scope by the eye bell.
Power and Range
Here are some suggested scope powers and the distances where they may be effectively used. Always remember that higher magnification optics and scopes will not be as effective as lower powered scopes since excessive zoom can be a bad thing. The same goes for longer ranges where the shooter needs sufficient power to see where to properly aim the rifle at the target.
Rifle Glass Lens Finishing
All contemporary rifle scope and optic lenses are covered in special coatings. There are various types and qualities of glass lens coatings. Lens finish can be a crucial element of a rifle’s setup when thinking of high-end rifle optics and targeting equipment. The glass lenses are one of the most critical pieces of the glass given that they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses safeguards the lens exterior and helps with anti glare capabilities from excess daylight and color perception.
HD Versus ED Lens Coatings
Some optic companies additionally use “HD” or high-def glass coverings that apply various processes, polarizations, elements, and chemicals to extract numerous color ranges and viewable target visibility through lenses. This high-definition finish is commonly used with more costly high density lens glass which drops light’s capability to refract by means of the lens glass. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be noticeable around items with well defined outlines as light hits the item from various angles.
Single Covering Versus Multi-Coating
Different optic lenses can even have different coverings applied to them. All lenses usually have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally functional in numerous kinds of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope maker and just how much you paid for it. Both the make and cost are signs of the lens quality.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” coated. This indicates the lens has multiple treatments applied to the surfaces of the glass. If a lens receives several treatments, it can indicate that a maker is taking numerous actions to fight various environmental elements like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This also doesn’t always indicate the multi-coated lens is much better than a single layered lens. Being “much better” hinges on the producer’s lens treatment technology and the quality of materials used in constructing the rifle glass.
About Anti-water Coating
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Many top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic covering.
Scope Installation Options
Installing solutions for scopes come in a couple of choices. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically come in quick release variations which use throw levers which allow rifle operators to quickly mount and dismount the glass.
Hex Key Rifle Scope Ring Mounts
Standard, clamp design 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 made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope install is fine for rifles which require a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and attach it to a different rifle. Numerous scopes can even be switched out if they all use a similar style mount. These types of mounts are convenient for rifle platforms which are transported a lot, to remove the optic from the rifle for protection, or for optics which are used in between multiple rifles.
Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can spoil a day of shooting and your expensive optic by triggering fogging and creating residue inside of the scope’s tube. The majority of optics protect against wetness from going into the scope tube with a system of sealing O-rings which are waterproof. Normally, 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 more than enough humidity prevention for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle on a boat and are concerned about the optic still working if it falls overboard and you can still rescue the firearm.
Gas Purged Optic Tubes
Another element of avoiding the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the scope is less influenced by temperature changes and pressure variations from the outside environment which could possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
