I’m looking into buying an aimpoint to replace an Eotech 512, and I wanted to know what advantages the M2 has over the T1, other than the obvious size and weight difference, and of coarse price. I like the look of the M2 better than the T1 (go ahead and make fun of me) but need to figure out whether I could possibly be jumping into something out-dated. Also, on the M2, are they availible with anything smaller than a 4 MOA dot? One thing I love about my eotech is the 1 MOA dot in the center; makes longer range varmint shots very easy.
Since you didn’t indicate that you intend to run night vision, I would go with either the ML2 or H-1 if the 4 MOA dot is acceptable or the ML3 if you want to get it with the 2 MOA dot. I think the 2 MOA dot is crisper than the 4 MOA but that may depend on your eyes.
Personally I use the T-1 for patrol and SRT but I need the NV capability otherwise it would have been the H-1.
In my world, red dot sights would be used for CQB anti-personnel use, not for precision target shooting so a 4 MOA dot is good for me and my aging eyes.
There are very good deals to be had on previously-owned M2 models–lower asking prices than the ML2. That being he case, I see no reason not to go with the M2 even if you don’t need NV.
I have an M2 and a T1. I much prefer the T1 for its size, weight and battery life. The T1 works for me much better than any other red dot or holo sight I have ever used.
