I’ve got the exact same set up on my .22 mag/20 gauge. It just about doubled the sighting radius and keeps the shotgun barrel usable. A scope on that o/u made the shotgun barrel all but useless for anything moving.
I didn’t realize that Savage made that silver receiver model with the barrel selector on the side like the real early 24’s. My silver 24H-DL barrel selector is on the hammer.
Nessmuk or anyone else, my buddy has an extremely nice .22 LR/410 m24DL with the silver receiver, grooved barrel and selector on the hammer that he wants to sell. He has his FFL so shipping isn’t a problem.
