Style: 4.3 Bullseye
Comparison of the two premier tritium powered 1x optics. I own both the Acog reflex and M21 now and I have to say it's a very tough choice which I would chose over the other. Main problem with both: Washout- these are powered with fiber optics and tritium. When it's dark, the tritium illuminates and reflects of the lens. When it is bright the fiber optics collect the light and then reflect it off the glass. So more light, a brighter reticle. Less light, a dimmer one. When shooting from a shaded or darker area, this is where the issue occurs. It is collecting little to no light and not producing a bright reticle. So if you were to aim the optic out to a brighter area, the reticle will disappear (washout). You are unable to see it and aim. Best at combating washout? Winner: Acog Reflex I own the bullseye model of the M21 and amber dot of the Acog. The color in the Acog is much richer and darker. The M21 is much lighter. In situations where the dot would wash out on the M21, the Acog was still visible. And if I took it to an extreme and pointed both at a light and covered the fiber optics up... Not an issue for the Acog ***main let down of M21*** No Polarizing Lens!!! The Acog comes with a lens that lets you adjust the opaqueness of the lens (like transitioning glasses). If it is bright out and you're shooting from a poorly lit area, you can use this lens to darken it and... You can clearly see the reticle. The fiber optics for the Acog sit at the front of it while the M21 is situated on top. So the type of light that you are shooting into will affect the reticle more on the Acog while the light your are shooting from will affect the M21 more. I have not been able to find a polaraizing lens for the M21. There is a washout remover that is available ( but requires batteries) which defeats the purpose of this type of optic. The lack of this lens is about enough for me to choose the Acog over the M21 even though I would say the M21 is superior in almost every other area. Build, feel, reticle, size, & bang for your buck. The M21 comes with a QD mount where you will have to spend another $100 for that on the Acog. The metal has a nice finish compared to the rougher texture on the Acog. The reticle type on the Bullseye model is great. Like if the Acog and Eotech had a baby. It's big and can be used for rapid acquisition where the amber dot Eotech will take some practice picking up quickly. Both are built like a tank and are in one solid piece. I do not doubt there ruggedness and would feel safe taking either one with me in the case of fall out. I have also had range time with the micro aimpoints (which are about $300 more) and would still chose either one of these over any red dot. Do. It for get both of these are still used today in combat and you won't go wrong with purchasing them. ***side note*** I also bought the MX3 magnifier that's goes with the M21. I would chose the Eotech G33 magnifier. The M21's lens has a teal hue that is ver pronounced with the use of a magnifier.

Haven't had a chance to try this unit out yet since I received it, but it seems to operate as well. The triangular reticule is much small than I thought and actually looks more like a dot. Nicely made, appears very sturdy since the body is mostly aluminum. Adapter works very well and makes taking this sight on and off very quick and easy. Will update as soon as possible. ** Aug 2013 ** OK, so I finally was able to test this sight our since I was able to acquire ammunition for my AR's (5.56 & 300 BLK). Keeping in mind that I am limited to an indoor range with a maximum 25 yard distance, I was very impressed with this sight. At that range, I was able to keep my shots clustered in a group of about 5" to 6" in diameter while rapid firing .... basically using a life size body shaped target, all rounds were kept dead center in the center of the torso where I had the triangle placed. My friend was impressed enough that he is thinking of buying on as well. Yes, there is a slight issue with washout when transitioning from a dimly lit to brightly lit area (for the target), but the triangle was still visible enough to allow me to keep 100% of my shots in the center mass of a human sized torso. ** Sept 2013 ** After working with this sight more on my various rifles & pistols, I have found it to be very accurate and has maintained zero perfectly when swapped between 5 different guns. Also it perfectly co-witnesses with my Troy Battle Sights. At nearly half the cost of a Trijicon SRS that I was considering, I plan to purchase several more for each of my rifles in the near future. My only gripes with this sight are: 1. No option to allow user to change reticle pattern or size 2. No option to change reticle color (reddish orange can be difficult to see on some surfaces) But that is all part of K.I.S.S. so have to make do with these limitations

Style: Triangle
I have a couple ACOG's and this sight. Between the two I really don't know if I could pick a "better" or "worse". The M21 is, like the ACOG, simple. It is also cheaper. I purchased the REM21 and polarizer with flash guard. I use the latter on the ACOG's as well and have been testing the REM ACOG with great results. The flash guard isn't really needed unless you are worried about the flash, the polarizer is nice to have installed and the REM's are just a "no brainer" especially on the M21 as it does not hinder any of the good things the sight does while adding really great things to it! Which would I buy if I could only have one of these sights? Tough call as I know the ACOG well and only just getting into the M21. The price point on the latter is better but the ACOG is a really solid sight. I really can't help with that dilemma.
