I have a flat top AR that I want to pick up an Eotech for. This is just going to be a relatively inexpensive, starter optic for me... So, I was going to pick up a new 512 for around $430 after tax.
Question is, I was scrolling through some local classifieds tonight and found a used 517 with a manufacture date of 9-08, that I can pick up for $400... should I consider this if it is in good shape. I had a hard time finding what advantages the 517 has over the 512, besides the control being on the side. I don't plan on magnification or night vision, by the way.
Is the 517 much of an improvement?
