An upper with no bolt carrier group was rested on wooden blocks. Pictures were taken with a Samsung SIII.
Eotech 552. Reticle was hard to see. Set to max brightness.
Aimpoint PRO. Reticle appeared clearer than in image.
ACOG TA01 Front sight base shadow was less visible then what the photograph shows.
Eotech 552. At max brightness (with week old batteries) I could barely see the reticle at max brightness.
The Aimpoint PRO looked better then what the photo shows.
Except for my finger in the picture, this photo well depicts the view thru the Aimpoint T1.
The ACOG reticle was crisper then what the photo shows, and the front sight base shadow less apparent.

Aimpoint VS. Eotech VS. ACOG VS. Aimpoint
I rounded up an Aimpoint PRO, Aimpoint T1 (4 MOA), an Eotech 552, and a Trijicon ACOG TA01 for a side to side comparison. To try and get an unbiased opinion, I had a friend use all 4 optics on the same firearm, shooting both groups and assorted drills.
Comparing reflex sights to magnified optics is like comparing motorcycles to semi-trucks, but the subject is of much debate online. The simple answer is that you need to select the optic that best suits your needs.
I had my friend start off by shooting groups at 25 yards. His groups with iron sights and all the reflex sights were about the same. However when he used the ACOG the group tightened up considerably. I believe that because of having magnification and a crosshair that he slowed down and focused on the shooting fundamentals.
At this point my friend most preferred the ACOG. After using the ACOG my friend stated, “This is more of a traditional scope, not a reflex or an ACOG.” I proceeded to tease my friend about this statement for the rest of the day.
As for the reflex sights, my friend preferred the Aimpoint T1 the most, and the Eotech the least. This Eotech had week old batteries and even at max brightness was hard to see in the Florida sunlight. I must note that this is an older Eotech and newer ones may be brighter.
After the grouping exercise I had my friend practice bringing a rifle up from a ready position and engaging multiple locations on a target at 10 yards. I started my friend with iron sights, then had him try the various optics. I was surprised that for my friend, he found the ACOG faster and more comfortable for quick shooting. Both the Aimpoint PRO and T1 were about the same, and the Eotech was still disliked due to it being dim and the reticle being cluttered.
Tried variations of multiple targets, and shooting left handed. All the same results. Trying to shoot left handed for my friend was awkward regardless of optic, but the reflex sights seemed to help.
While I was at the range, I got the chance to talk to a former Army officer and had him look over the various optics. Without shooting with them, he came to the same conclusion that my friend did. The Aimpoint T1 was the preferred optic, with the PRO being second choice. The Eotech was disliked due to being dim. My friend thought the Eotech reticle was cluttered and preferred just the dot in the reflex sights. While they both liked the ACOG, both would have taken an Aimpoint over it.
When I asked about the difference in dot sizes or window size preferences, neither my friend nor the former Army officer noticed a difference, but they both liked the Aimpoint T1 better.
Personally, I used to be a big Eotech fan but then I had mine fail me. Eotech’s record of failures keeps me from being able to like them anymore. While I much prefer the Aimpoint T1, I highly recommend the Aimpoint PRO as the economical optic choice. There are few bigger ACOG fans then myself, but I don’t believe that the ACOG is the right optic for most shooters, and that for the majority of people who plan to use their carbine as a home defense or close range firearm are better suited with a good Aimpoint over a magnified optic ACOG.
