I've read of a non-trivial number of people online having trouble zeroing the EPS Carry due to not enough adjustment. 507K is still the one to beat, IMHO.Let's see... f ton of notch filter, you can't adjust it for brightness or point of impact, and the 15 moa dot is gigantic. That and it's still 100 bucks. Hard pass. It's hard to beat the fully enclosed k footprint eps carry right now.
