Actually not only did they throw the DD AR with the Aimpoint T-1 out of a helicopter from a couple of hundred feet twice (a do over was called for since their primary camera wasn't running to catch the first drop) they also blew up a car with the DD AR hanging from the rear view mirror during their thorough torture test. The tortured T-1/DD AR combo held zero until the helicopter drops, and I suspect the reason why it lost zero from the 1st and/or 2nd helicopter drop is because the AR probably landed muzzle first and that impact affected the barrel or the barrel to upper interface and wasn't actually an issue with the T-1.
I have several T-1s, T-2s, and a H-2. The only thing I've been able to find out about the difference between the T-1/H-1 and T-2/H-2 is Aimpoint claims less parallax error with the later T-2/H-2 version. I've also noted that the red dot is brighter on the highest setting on the T-2/H-2 vs. the T-1.
That Daniel Defense AR is on display in the Daniel Defense lobby. Aimpoint asked for the T-1 and DD refused to hand it over, preferring to keep it on display with their torture tested AR.
I have more faith in Aimpoint than any other brand RDS optic.
