I bought a Model 50 20 gauge skeet gun with VR from a friend a couple of years ago.
If you like braking targets and don't like recoil, it's a perfect gun.
Although I haven't shot it a great deal, but I've never had any mechanical issues with it.
My friend, who collected Model 50's said that the aluminum receiver guns were good for 15,000 rounds and then the receiver would crack. Mine's steel.
