"YOU'LL PUT YOUR EYE OUT WITH THAT THING"
Seriously, while peep sights are best used as close as possible to the eye, and the tang peep sight the closest of all, it's not a good idea on a long gun that has a lot of comeback, as it makes the possibility of eye damage a reality.
IMO, you'd be better off mounting a reflex sight on a low Weaver base for slugs/deer, and QD it for bird hunting.
