I like my bear burgers on the grill over a nice bed of coals. Roasts I like to do in a Dutch Oven on a grate so the juices are below the meat and the meat is not resting in the juices. They make grreat sausages too!
You'll actually like the peep on the GPR flinter. It sort of hides some of the flash in front of your eye and cocking the hammer is no problem.
I have them on my .50 and .54 GPR's and on the .50 Deerstalker flinters.
