I've used open sights for buff, I've used 3-10 x 50. A scope is handy peering into the shadows tracking them during mid day in the thick jess bush and other thick stuff.
20mm leaves a FOV a bit too restricted for my taste. 32mm is fine. I always thought a red dot sight would be good, but never wanted to do the durability testing to get the confidence that it would not crap out at the wrong moment.
