I just sent my Vortex Strikefire back to Vortex for the 3rd and final time. The red dot will not turn on. It is the third time I have sent it back for this issue. Time to pony up some cash and get a high quality red dot sight. I am having trouble decidng between EOtech and Aimpoint. Any advice? I am looking the EOTech HHS I/II or the Aimpoint Comp M4/M4s w/ magnifier. Anyone have any experience with these? Durability and reliability being my main concern.
