This is my 11th Holosun optic to date. Yes, I like them to start with, especially the vulcan redical. It absolutely helps, or speeds up the time it takes to find the dot. Aids with having confidence that in nerve racking situation you are going to prevail. I have both the 507c Volcan, and the 507k Vulcan. I find the smaller the firearm the more this redical is appreciated.
