Versus the Aimpoint, I went with the trijicon because I just don't like an Aimpoint. My brother has a ML3 that is rapidly changing my mind though.
The Clarity is the same, one thing I do like about the trijicon vs the aimpoint is the chevron, when you're swinging up from a lowready position
the tip of the chevron gives me a bit of an edge over the aimpoint.
Also, I can use the chevron for rough range finding, the tip is set at 25 metres, place the tip just below (6 o clock hold), and boom you're on target.
At 100 meters, place the tip on your target and at 200 metres, use the inside of he chevron.
F.O.V. is about the same I still have the battery compartment blocking some but that's what starboard assisant gunners are for.
I really, really like the Unimax, I zeroed it at 25 meters, and had to do some filing on the switches to get it to fit but the brightness and pulsing really help you pick it up even in daylight. I have a tape switch on backorder, so I won't have to move my support hand to activate it.
It's really there just as a back-up to my buis. So far it's worked really well on plate runs and some CQB- type drills I've run through.
Don't lose the adjustment tools though, them suckers are way tiny!
