Can’t say enough good things about eotech - EOTech 510 Series 512-A65 Holographic CQB Weapon Sight

This is my 6th EOTech. I have them on a verity of military type rifles some of which have been in service for over twenty years. At around the two decade mark I’ve had to replace the battery contact pads, a few minute replacement. Some of these rifles have seen years of competition and subjected to every type of abuse and have the scars to show for it and I’ve never had one fail.
