This Trijicon ACOG riflescope offers magnification of 4x with a 32-millimeter objective. The scope is equipped with a day/night dual-illumination Chevron Bindon Aiming Concept (BAC) Reticle that provides battery-free operation by illuminating with fiber optics during daylight and a tritium phosphor lamp at night. The ranging reticle is calibrated for 5.56 (0.223 cal) flattop rifles out to 800 meters. The Chevron Reticle is designed to be zeroed using the tip at 100 meters. The width of the Chevron at the base is 5.53 MOA, which is set at 19 at 300 meters, allowing for range estimation for silhouette targets. The scope comes with a Picatinny flat top rail adapter for mounting, a fitted neoprene Scopecoat that protects the scope when it is mounted on the rifle, and a large storage case.
Trijicon ACOG Riflescopes:
Trijicon ACOGs are internally-adjustable, compact telescopic sights with tritium illuminated reticle patterns for use in low light or at night. The Bindon Aiming Concept (BAC) scopes feature bright daytime reticles that use fiber optics to collect ambient light and automatically adjust the brightness to meet available light conditions. The ACOGs combine traditional, precise distance marksmanship with close-in aiming speed. Every feature of each scope's mechanical and optical design was chosen for a single purpose: to provide increased hit potential in all lighting conditions--without failure-prone batteries. Key features include:
- Totally Battery-Free Trijicon Tritium-Phosphor Lamp: Trijicon ACOG delivers increased hit potential in all lighting conditions--without the use of batteries--thanks to a combination of world class optics and tritium illuminated reticles that glow day and night. The fiber optics automatically adjust the brightness level and contrast of the reticle to available light conditions. The tritium-phosphor lamp glows in low-light conditions for quick target acquisition. The lamp is guaranteed to illuminate for 15 years.
- Trijicon Fiber Optics: Automatically adjust the brightness level and contrast of the Trijicon reticle to available light conditions.
- Broad Band Anti-Reflective Coated Lenses: Multi-coated lenses provide superior clarity and light gathering capabilities with zero distortion.
- BAC--Bindon Aiming Concept: The BAC allows the shooter to track and engage targets faster by utilizing an illuminated aiming point instead of traditional black cross-hairs. When making dynamic movements with both eyes open, vision naturally focuses on the unmagnified view while still perceiving the illuminated aiming point. As soon as the weapon begins to steady in the target area, the brain switches to the magnified view along with the aiming point.
- BDC--Bullet Drop Compensation: BDC is designed to compensate for the effect of gravity on the trajectory of the bullet without requiring mechanical adjustments to the sight (distance depends on model). Trijicon BDC reticles are calibrated for specific bullet rounds. When zeroed properly, the sight is ready for aim at a multitude of distances without further adjustments.
- Large Eye Volume: Allows you to quickly acquire targets, even if you're not positioned perfectly behind the scope.
- Waterproof to 500 feet/150 meters and dry-nitrogen filled to eliminate fogging.
- Military Grade Aluminum Housing: Forged 7075-T6 aircraft-aluminum-alloy housing provides for a nearly indestructible sighting system.

I used this sight in the Army during my first deployment to Iraq. Its excellent, don't know how many times my rifle and acog got banged up that year but it was plenty to break most optics, but not this one. The reticle itself is an up arrow so its easy to maintain your sight picture. Its practically useless at night for obvious reasons, unless you hook up nods (night vision) right behind it. Other than that, its great for targets 75m+

The Trijicon ACOG is the tried and tested version of the ACOG TA31 series. The sight uses the inverted 'V' reticle which is fast but allows food precision at range. The ACOG series as a whole are one of the most robust optics I have ever used since I took an ACOG TA01 ACOG to Iraq in 2004.
Though I don't recommend it you could probably hammer tent spikes in with them with little actual damage. When it comes to a very rugged fixed magnification optic that has been combat proven the ACOG has little competitions. The ELCAN M145/C79 is an option but suffers from being very heavy and also external windage and elevation adjustments. The British SUSAT does not even compare as can be seen buy the UK forces now issuing ACOGs for use on their L85s in high numbers.
The TA31F uses dual illumination in the form of fiber optics and tritium. I've found that very bright light as was common in Iraq would cause the reticle to glow too bright to be used precisely. A fix to this is to cover part of the fiber optic with gaffers or duct tape. I've found with practice the 'Bidon Aiming Concept' to be very easy to use thanks to the bright chevron. That said personally I found it easier to use with a scope cap covered blocking all magnification. This may sounds silly at first but with two eye open aiming the brain will superimpose the red 'dot' over the image the other eye is seeing. This also works with red dot style sights and is one reason ranging binoculars have ranging lines in only one monocular.
The ACOG is expensive, almost to its fault. That said due to its high quality and ruggedness you definitely get what you are paying for. Its is by no means 'better' or a replacement for a red dot style optic, it serves a different mission profile. If you need the utmost in reliability and the magnification it offers you will not be disappointed by the ACOG.

i have one of these mounted on my stag model 8. overall, the best optic i have ever used. the BAC (bindon aiming concept) takes a little getting used to. basically, it is a "both eyes open" shooting concept in which at close distances, you do not notice the magnification of the optic and the reticle is seen on the close range targets. it does take practice to train you brain and your eye to get used to this but once you have it down, it allows for quick 1x target acquisition. at close range, with-in 50 yards, the aimpoint comp m3 sight is faster but at distance over 50 yards, the acog cannot be beat. the optic is callibrated to the 5.56 cartridge and the reticle has bullet drop compensators out to 800 meters. in order to properly use this feature, you must do a proper 100 meter "zero". once the optic is zero'd in, which does not take much, its pretty close out-of-the-box, it will hold its zero when removed from your rifle and returned to the same mount point. i actually took the acog off of my rifle, placed it on my brother's bushmaster, and the thing was nearly dead center. put it back on my rifle and first shot was dead center. that impressed me.
it should be mentioned that if you are accustomed to an aimpoint or eotech, the eye relief of the acog is not as good. typically, you need to be no farther than 1.5 inches to get the full field of view in the acog, whereas the aimpoints and eotechs have unlimited eye relief. with the factory mount, it sits low on the flat-top. i would suggest to get a larue quick-detach acog mount and the 5/8 inch riser to get the optic up to a good shooting level. i bought the larue RCO mount and with the riser, the acog sits just where it needs to be to clear my rear iron sight and allow me to have proper head and cheek alignment to get the full field-of-view through the optic. with this pairing, the eye relief is not and has not been an issue for me.
finally, the only other deterrant in getting this optic is the cost. most of these with the dual illumination run about $1100-1200, which is steep, but the optic is top-notch and is, in my opinion, worth the investment if you can afford it. my shooting buddies argue for the aimpoint because of the price and quality of that optic. i've shot aimpoint and i love the optic but lets consider the true cost of it. 1: the out-of-the-box cost is $569. 2: the comp m2 and m3 do not come with a mount. to get a quality mount, you will spend another $120 for a larue or daniel defense product. 3: if you want magnification for shooting past 50 yards, you will have to spend another $500 to get the 3x magnifier. all together, the cost is pretty close.
i am not trying to push for the acog as i have used both aimpoint and eotech and cannot say anything negative about either. i just want to give my experience with the acog and some real-world input on the eotech, aimpoint, and acog, all of which i have shot extensively. depending on your requirements and shooting needs, no matter which you go for, you will not be sorry.
