Very good quality, and seems to be pretty much "Idiot, and Bullet proof". Mounted it in a high LaRue QD mount and it co-witnesses perfectly in the bottom 1/3 of the optic.
Wih 50,000 hours of battery life, it'll be on 24/ 7 for more than 5 years. The only issue with all RDS optics, is selecting the right brightness for the condition. Fortunately it has 9 settings. 4 NVD, and 5 non NVD.
Need to wring it out in training to see iof it's as fast as my EOTech 512 F was at CQB distances. Most say not quite as fast.
I drank heavily on the eo-tech koolaid but after I actually got some time with my aimpoint I ended up liking it and becoming just as quick with my aimpoint.
