Setting up a new rifle but have been out of the need to get a red dot for awhile and not versed on the new hotness. What is the PF group think on red dots for rifles? Been looking at Holosun HS503R, HS503CU, Vortex options, Aimpoint Pro, etc. Originally planning to spend $300ish but am flexible if the answer is "Aimpoint Pro and don't look back". If the answer is Holosun - what is the preference in switchology (dial (503R) or buttons (503CU)). I've always liked the dial on my Aimpoint T1 but I don't know what I don't know. Thanks in advance!
