Plus 1 on the peep. Before I found that scopes were the best bet for my eyes, I had a couple rifles that wore peeps only. They were my carry choice on rainy days when I was hunting the closed in swamps in northern Michigan, ... Wilderness State Park to be more precise.

When the day got short and dark I'd just unscrew the apeture and use the threaded body only as a ghost ring for the last few minutes of shooting light. But that was years ago for me. At 60 yrs old, and with my current eyesight, I'll be using scopes for just about everything now.

i do have a 6.5 X 55 Swede 94 though, and it wears a scope mounted on the old Weaver pivot mounts. Though it does not return to a perfect POI when switching it over to irons and back again to scope, it allows me to flip the scope out of the way to use the iron sights in the event I have real close shots in lousy weather when my scope is way too rained-stained.
