On my 24F I use a scope (for the rifle) and see thru rings for the open sights (shotgun)
I prefer to use QD rings on Savage 24s, so the scope can be quickly removed if the shotgun barrel is going to be used. The Durasight QR rings are inexpensive and have an integral recoil lug, unlike the Warne QR Maxima rings, so they are a quick and easy on and off. They come in 2 heights, medium and high, and 2 colors, black and silver.
DS403B = high - black
DS400B = medium - black
DS403S = high - silver
DS400S = medium - silver
www.durasight.comI always run a PT&G alignment reamer through these rings before I use them, as I have run across a couple that still had a bit of mold spruce on them that would probably scratched a scope tube if they weren't removed.
EDIT: You can usually buy these rings on eBay for under $25.
