I've got a 24V (.223/20ga) from the '80s and a 24F (.223/12 ga) from the '90s. The 24V is the favorite. Its wooden stock has a Monte Carlo hump which makes it more of a rifle stock.
The 24F's plastic stock has a straight comb and much more drop. It's more like a shotgun stock. It has choke tubes where the 24V does not.
The guns are a mixed bag. They take some getting used to before you can break clay pigeons with them. Worse than that, you get used to one, you won't hit well with the other.
The 24V is better finished and has mirror bright bores. The polishing step must've been skipped in the 24F as both bores are rough with tool marks. Cleaning the 24F takes longer as a result. Its rifle bore never really seems clean.
The rifle barrels on both are quite accurate. They shoot MOA at 100 yards if you take your time and keep the barrel cool.
The shotgun patterns on both seem poor. Very uneven and not regulated well with the rifle sights. Not hard to see why getting hits on clay pigeons is difficult.
With 12 ga. 3" magnums, the 24F is a bruiser.
I've always enjoyed my time afield with these guns. Without a scope, they're handy to carry and you feel ready for anything. Adding a scope makes them heavy, considerably less handy, and eliminates any wing-shooting capability. But it does cash in on the rifle's accuracy potential.
One caution: Don't dry fire them without a snap cap. Broke the spring that retracts the shotgun firing pin on the 24V by dry snapping mine. Took awhile to find someone to fix it.
