Based on my nephews comments, one career Army Ranger with service in 1st Gulf war, Iraq and Afghansitan, the other Marine Recon, Army LERP, Iraq and Afghansitan. They both have used various red dot sights in combat and they go for the Aimpoint, not cheap but when TSHTF, why would you trust your life to a cheap sight. That is what eventually I'll put on my evil black gun.
